Dear Poet Friends, I conclude this series on The Enigma of Time by mentioning few important features about the concept of Time according to Modern Philosophy and Science. I have used a
simple format, and also tried my best to simplify the concepts for your kind appreciation. Unfortunately, there is no provision on this Poetry Site to show Diagrams to elucidate! If you like this one, kindly repost the same for wider circulation! Thank you, Raj Nandy, New Delhi.
            
       CONCLUDING THE ENIGMA OF TIME IN VERSE:
                      PART THREE – BY RAJ NANDY
              
              TIME ACCORDING TO MODERN PHILOSOPHY

UNREALITY Of TIME : Mc Taggart’s ‘A’ and ‘B’ Series:
Now skipping through the pages I come to Modern Philosophy, with Mc Taggart the British philosopher of the 20th Century.
He had acquired a substantial following with his 1908 paper on the ‘Unreality of Time’ initially.
With his quibbling argument he states, that moments in his ‘A’ Series of Time are either of past tense, present tense, or of future tense.
It is all about human perception, since we experience the past through our memories;
Become aware of the present through our senses, while future is pretty unknowable.
Here time appears to be flowing through us, as nothing remains stable around us!

In his ‘B’ Series of Time Mc Taggart expresses differences in moments of time as either Before or After,
Without using the tenses used in his ‘A’ Series of Time.
All parts in time can be expressed equally as points along a time line, in the absence of past, present, and future tense;
While here we appear to be flying through time in a metaphorical sense!
Thus in the ‘A series’ time appears to be flowing through us, but in ‘B series’ we seem to be flying through time on a timeline created by us!
Therefore, Mc Taggart finds both the ‘A’ and ‘B’ Series describing Time to be inadequate and also contradictory;
And he finally concludes that Time is unreal and does not exist in reality!

How Mc Taggart’s Theory Was  Updated :
Modern Philosophers have re-casted Mc Taggart’s theory in term of findings of Modern Physics.
His A-Theory is updated into ‘PRESENTISM’, which holds that only thing that is real is the ‘present moment’.
In ‘Presentism’ time has no past or future, and time has no duration either!
All things come into existence and drop out of existence, and past events no longer exist;
And since the future is undefined or merely potential, it too does not exist!

His B-theory is re-formulated into ‘ETERNALISM’ or the ‘Block Universe’, influenced by the later Theory of Relativity.
‘Eternalism’ holds that past events do exist even if we cannot immediately experience them, and future events also exists in a very real way.
The ‘flow of time’ we experience is just an illusion of consciousness.
Since in reality, time is always everywhere in an eternal sense!

Theory of Growing Block Universe:
It was proposed by the Englishman CD Broad in 1923, as an alternative to ‘Presentism’ where only the present exist;
And also as an alternative to ‘Eternalism’ where past, present, and future together also exist.
In ‘Growing Block Universe’ only the past and the present exist, but not the future.
Since the growing of the block happens in the present, with a very thin slice of space-time continuously coming into existence;  
Where consciousness as well as the flow of time are not active within the past,  
But they can occur only at the boundary of this ‘Growing Block Universe’!
Few scholars this concept did criticise, saying that in this theory the word ‘now’ can no longer be used to define Time!

But according to Einstein, this perception of ‘now’ that appears to move along a timeline, creating the illusion of ‘flow of time’, arises purely as a result of human consciousness;
And the way our brains are wired due to our evolutionary process, enabling us to deal with the world around us in a practical sense.
“People like us, who believe in Physics, know that the duration between the past, present, and the future is only a stubbornly persistent illusion,’’ said Einstein.

A poem on ‘The Paradox of Time’:
Now to lighten up my Reader’s mind, I present only the first three stanzas from ‘’The Paradox of Time’’, composed by the British poet Austin Dobson:
  “Time goes, you say? Ah no!
   Alas, Time stays, we go;
      Or else, were this not so,
  What need to chain the hours,
  For youth were always ours?

  Ours is the eye’s deceit
  Of men whose flying feet
     Lead through some landscape low;
  We pass, and think we see
  The earth’s fixed surface flee,
     Alas, time stays, we go!

  Once in the days of old
  Your locks were curling gold,
     And mine had shamed the crow.
  Now, in the self-same stage,
  We’ve reached the silver age,
  Time goes, you say? - ah no!
       Alas, time stays, we go!”
            
HOW LIGHT IS CONNECTED WITH THE CONCEPT OF TIME:
Brief Background:
I commence with quotes from the ‘Book of Genesis’ - Chapter One, along with my thoughts about Light and Time,
Before concluding this series with Albert Einstein’s concept of Space-Time.

“And God said, “Let there be light,” and there was light. God saw that the light was good, and he separated the light from the darkness. God called the light “day,” and the darkness he called “night.” And there was evening, and there was morning—the first day. ……And God said, “Let there be lights in the vault of the sky to separate the day from the night, and let them serve as signs to mark sacred times, and days and years, and let them be lights in the vault of the sky to give light on the earth. And it was so.”
                                                      - BOOK Of GENESIS Chapter One.

Since ancient days, Light had acquired a religious and a spiritual significance.
Since Light became associated with goodness, intelligence and ultimate realty;
Light accompanies transcendence into Nirvana of Buddhist religious philosophy.
In due course the Sun began to be worshipped as an important live-giving deity.
As seen in the symbolic form of Egyptian Sun God Ra, and the Greek gods Helios and Hyperion as the Sun god and god of Light respectively.
In Hindu mythology Surya is the Sun god, and Ushas the goddess of Light.
Huitzilopochti, both the Sun god and god of War of the Ancient Aztecs was kept pleased with human sacrifice!

SOME PROPERTIES OF LIGHT:
Plato, during the 5th Century BC said that God was unable to make the World eternal, so gave it Time,  - “as the moving image of eternity.”
While some seven hundred years later St. Augustine in his ‘Confessions’ said,
That when God created the universe out of darkness with light, “the world was also created with Time, and not in time.”
Thus along with light, time also began to flow, while our scientists discovered a connection between the speed of light and time, few centuries ago!
To understand this connection between light and time, we must first understand something about the properties of light.
Light is the visible part of the electromagnetic spectrum* which can be perceived by our human eye.         (See Notes Below)
As seen in the red, orange, yellow, green, blue, indigo, and violet colors of the Rainbow in the sky,
When water droplets acting like countless prisms break up white sunlight!
Now this electromagnetic spectrum also contains the ultra violet and infra red spectrum which our eyes cannot see.
But this entire electromagnetic spectrum contains Photons, which are discreet packets of zero mass less energy.
In a vacuum light photons travel at 186,000 miles for second, which Einstein declared as the cosmic speed limit, and as an universal constant.
When a photon strikes the eye, it is turned into electrical energy that is transmitted to the brain to form an image which we call sight.

NOTES : Gama-rays, X-rays, Ultraviolet lights, have shorter wave lengths & more energy than Visible light. But Infrared, Microwave, Radio waves, with larger wave lengths are less energetic than the Visible spectrum of light. Sir Isaac Newton using a prism had discovered the spectrum of visible light, & used the word ‘spectrum’ for the first time in his book ‘Optick’ in 1671.

EINSTEIN'S SPECIAL THEORY OF RELATIVITY 1905 :
In his Special Theory of Relativity of 1905, he stated that nothing can move faster than speed of light which is 186,000 miles per second.
This speed of light always remains the same, irrespective of its source and frame of reference.
Now the mass of an object would double if it travels at 90% of light’s speed.
But if the speed of light is reached, mass of an object would become infinite!
Since photons, the quantum particles that make up light have a zero mass, they move at the speed of light.
Even inside the World’s Largest Particle Collider (LDC), located near the French-Swiss Border,
Experiments are carried out only around 99.99% of Light’s speed, in accordance with the Laws of Physics.
Einstein had also shown mathematically that on reaching Light’s speed, Time will come to a standstill!
And should this Light’s speed be exceeded, then Time would start to travel backwards, which becomes a mind boggling concept!
Here we enter into the realm of science fiction, which has been described by HG Wells  in his popular novel ‘The Time Machine’.
But to become a time traveler shall always remain our cherished desire and dream!

NOTES: Only mass less particles like the photon can travel at light speed, photons experience no time, they do not age. Objects with mass cannot reach the speed of light since in that case its mass will become infinite. Also, one cannot see the fourth dimension because of Lorenz Contraction, which is also related to stopping of time, for at the speed of light an object will shrink to zero length! Also, particles interact with the Higgs' Field present all around to pick up mass, excepting photons which do not interact with this Higgs' Field.

Now Einstein’s theory of 1905 is called ‘Special’, because it explains how space and time are linked for objects that are moving in a straight line at a greater speed but which is constant.
Time moves relative to the observer, and objects in motion experience ‘Time Dilation’.
Meaning, time moves slowly when it is in motion, as compared to one who is standing still, -  a relative comparison.
This can be further explained by the ‘Twin Paradox’, where a 15 year old travelling in a spaceship at 99.5% speed of light for a period of 5 years,
Returns back to Earth to find himself to be only 20 years old.
But to his surprise he finds, his twin brother on Earth who was left behind, has reached the ripe age of 65 !

Limitations of Special Theory of Relativity:
It was confined to non-accelerating bodies only, and after ten years of deliberation,
Einstein added gravitational force field, space-time curvature, and acceleration, -
To formulate his General Theory of Relativity with satisfaction.

   SPACE-TIME & GENERAL THEORY OF RELATIVITY 1916 :
Isaac Newton during the 17th Century spoke about 'absolute time' and 'absolute space', accordance to the understanding of science of his Classical Age.
Space was the arena where the drama of the universe was played out, and this arena was passive, eternal, and unchanging no doubt.
Time too was absolute with an independent existence, and continued to beat independently like the heart beat of Space!
Newton also gave us the Laws of Motion, and Gravity, with more massive objects exerting more Gravity than a less massive one in reality.
Now one aspect of Special Relativity is that space and time are merged into a four-dimensional space-time entity,
They do not exist as separately as envisaged by Newton and Descartes during the 17th Century.
Some 250 years later Albert Einstein, defined Gravity as a curvature of Space-time.
Einstein also tells us that gravity can bend light, which travels along the curvature of this space-time.
Gravity is flexible, it could stretch like a fabric warping of space-time caused by objects present within it, in fact Gravity is the shape of space-time itself!
The Moon rolls around the curvature created in space-time fabric by the heavier object the Earth,
Just like the massive Sun which creates the depression and curvature around it for the planets of our solar system to orbit round the Sun. *
Einstein’s space-time has been likened to a stretched out vast rubber sheet,
Where heavier the planet, more depression it creates on the fabric of space-time along with its own gravitational field.
Einstein’s Space is not passive like that of Newton, but has a dynamic presence.
Interwoven with Time, Space tells Matter how to move, while Matter tells Space-Time how to curve - in this dynamic presence!
The constant speed of light at 186,000 miles per second, is just a measure of space of something which travels over time;
But both space and time had to adjust themselves to accommodate the constant speed of light!
Thus space, time, and the speed of light are all unified in the General Theory of Relativity,
We owe all this to Albert Einstein, one of the greatest scientists of our Century.
NOTES: **Planets orbiting the Sun do not fall back into the void of space due to the attraction of gravity, and also due to their individual speed of acceleration maintained in orbit as per Kepler's Second Law of Planetary Motion. Mercury has the fastest orbital speed of 48 km per second, Venus at 35 km per sec , and Earth at 30 km per sec. as their orbital speeds. Planets further from the Sun require lesser orbital speed.

UNFINISHED WORK OF EINSTEIN:
During his later years Einstein was secretly working to find a ‘Theory of Everything’,
Which would ultimately replace the erratic tiny micro world of Quantum Mechanics.
His Theory of General Relativity had dealt with the functions of gravity at the greater macro level of the universe only.
So he hoped to extend this theory to find an all embracing Unified Field Theory.
For at the subatomic quantum level, as the Englishman Thomson discovered in 1897,
The electrons inside an atom at times behaved in an alien fashion and were very unstable!
This world of the subatomic particles is a wondrous world where time becomes chaotic;
Where the position of the electrons cannot be predicted with certainty!
Einstein called this unpredictable and unstable behaviour of electrons as "spooky action at a distance"!
In the ‘double-split experiment’ it was seen, that the light photons behaved both like waves and as particles, -
Even though the speed of light remained constant.

EINSTEIN'S NOBLE PRIZE For PHYSICS AWARDED IN 1921:
Now despite Einstein's dissatisfaction with Quantum Mechanics it is rather ironical,
That the Nobel Prize in Physics was awarded to Einstein for his work on the ‘Photoelectric Effect’ at the Quantum level;
Which for the first time had suggested that Light travelled in Waves and also as Particles ( i.e. as photon)!
This observation led to the development of electron microscope, solar panels, night vision devices, at a later date.
Since his Special and General Theory of Relativity considered as ‘The Pillars of Modern Physics’, was still being examined by the Scientific Community;
And they could be proved and accepted only subsequently.

'STRING THEORY' PROPOSED AS THEORY FOR EVERYTHING:
During the 1970s the proponents of ‘String Theory’ had claimed, They found a Theory of Everything, following Einstein’s quest.
They claimed that micro vibrating open and closed looped strings gave rise to some 36 particles at the subatomic level;
But also required 10 dimensions for this 'String Theory' to operate!
In our Standard Model of Physics we have only 18 particles as on date, therefore due to lack of scientific evidence,
There was no Noble Prize for those ‘String Theory’ proponents!
Efforts are on to find a Unified Theory of Everything, and to understand the mysteries of God’s infinite universe, -
We finite humans have just made a beginning!

Now, to reduce the length of my composition I conclude with a short verse by the famous novelist and poet DH Lawrence, -
Who had shocked Victorian England with his explosive ****** novel “Lady Chatterley’s Lover”,
Which later inspired Hollywood, and a film got made.

               RELATIVITY
“I like relativity and quantum theories
because I don’t understand them,
and they make me feel as if space shifted about like
a swan that can’t settle,
refusing to sit still and be measured;
and as if the atom were an impulsive thing
always changing its mind.”  – DH Lawrence.

THE LEGEND OF HOLLYWOOD IN VERSE
Dear Readers, I have tried to cover the salient features of this True Story in free flowing verse mainly with end rhymes. If you read it loud, you can hear the chimes! Due to the short attention span of my readers I had to cut short this long story, and conclude with the
Golden Era of Hollywood by stretching it up to the 1950's only. When TV began to challenge the Big Screen Cinema seriously! I have used only a part of my notes here. Kindly read the entire poem and don't hesitate to know many interesting facts - which I also did not know! I wish there was a provision for posting a few interesting photographs for you here. Best wishes, - Raj Nandy, New Delhi.  

                 THE LEGEND OF HOLLYWOOD :
                        THE AMERICAN  DREAM
                             BY RAJ NANDY

           A SHORT  HISTORICAL  BACKGROUND
Since the earliest days, optical toys, shadow shows, and ‘magic
lanterns’, had created the illusion of motion.
This concept was first described by Mark Roget in 1824 as  
the 'persistent of vision'.
Giving impetus to the development of big screen cinema with its
close-ups, capturing all controlled and subtle expressions!
The actors were no longer required to shout out their parts with
exaggerated actions as on the Elizabethan Stage.
Now even a single tear drop could get noticed easily by the entire
movie audience!
With the best scene being included and edited after a few retakes.
To Thomas Edison and his able assistant William Rogers we owe the invention of Kinetoscope, the first movie camera.
On the grounds of his West Orange, New Jersey laboratory, Edison
built his first movie studio called the ‘Black Maria’.   (1893)
He also purchased a string of patents related to motion picture
Camera; forming the Edison Trust, - a cartel that took control of
the Film Industry entire!

Fort Lee, New Jersey:
On a small borough on the opposite bank of the Hudson River lay
the deserted Fort Lee.
Here scores of film production crews descended armed with picture Cameras, on this isolated part of New Jersey!
In 1907 Edison’s company came there to shoot a short silent film –
‘Rescue From an Eagle’s Nest’,
Which featured for the first time the actor and director DW Griffith.
The independent Chaplin Film Company built the first permanent
movie studio in 1910 in Fort Lee.
While some of the biggest Hollywood studios like the Universal,
MGM, and 20th Century Fox, had their roots in Fort Lee.
Some of the famous stars of the silent movie era included ‘Fatty’
Arbuckle, Will Rogers, Mary Pickford, Dorothy and Lillian Gish,
Lionel Barrymore, Rudolph Valentine and Pearl White.
In those days there were no reflectors and electric arch lights.
So movies were made on rooftops to capture the bright sunlight!
During unpredictable bad weather days, filming had to be stopped
despite the revolving stage which was made, -
To rotate and capture the sunlight before the lights atarted to fade!

Shift from New Jersey to West Coast California:
Now Edison who held the patents for the bulb, phonograph, and the Camera, had exhibited a near monopoly;
On the production, distribution, and exhibition of the movies which made this budding industry to shift to California from
New Jersey!
California with its natural scenery, its open range, mountains, desert, and snow country, had the basic ingredients for the movie industry.
But most importantly, California had bright Sunshine for almost
365 days of the year!
While eight miles away from Hollywood lay the port city of Los Angeles with its cheap labour.

                        THE RISE  OF  HOLLYWOOD
It was a real estate tycoon Harvey Wilcox and his wife Daeida from
Kansas, who during the 1880s founded ‘Hollywood’ as a community for like-minded temperate followers.
It is generally said that Daeida gave the name Hollywood perhaps
due to the areas abundant red-berried shrubs also known as
California Holly.
Spring blossoms around and above the Hollywood Hills with its rich variety,  gave it a touch of paradise for all to see !
Hollywood was incorporated as a municipality in 1903, and during
1910 unified with the city of Los Angeles.
While a year later, the first film studio had moved in from New
Jersey, to escape Thomas Edison’s monopoly!    (1911)

In 1913 Cecil B. De Mille and Jesse Lasky, had leased a barn with
studio facilities.
And directed the first feature length film ‘Squaw Man’ in 1914.
Today this studio is home to Hollywood Heritage Museum as we get to see.
The timeless symbol of Hollywood film industry that famous sign on top of Mount Lee, was put up by a real estate developer in 1923.  
This sign had read as ‘’HOLLY WOOD LAND’’ initially.
Despite decades of run-ins with vandals and pranksters, it managed to hang on to its prime location near the summit of the Hollywood Hills.
The last restoration work was carried out in 1978 initiated by Hugh
Hefner of the ******* Magazine.
Those nine white letters 45 feet tall now read ‘HOLLYWOOD’, and has become a landmark and America’s cultural icon, and an evocative symbol for ambition, glamour, and dream.
Forever enticing aspiring actors to flock to Hollywood, hypnotised
by lure of the big screen!

                     GOLDEN AGE OF HOLLYWOOD
The Silent Movie Era which began in 1895, ended in 1935 with the
production of ‘Dance of Virgins’, filmed entirely in the island of Bali.
The first Sound film ‘The Jazz Singer’ by Warner Bros. was made with a Vitaphone sound-on-disc technology.  (October 1927)
Despite the Great Depression of the 1930s, this decade along with the 1940s have been regarded by some as Hollywood’s Golden Age.
However, I think that this Golden Age includes the decades of the
1940s and the 1950s instead.
When the advent of Television began to challenge the Film Industry
itself !

First Academy Award:
On 16th May 1929 in the Roosevelt Hotel on Hollywood Boulevard,
the First Academy Award presentation was held.
Around 270 people were in attendance, and tickets were priced at
$5 per head.
When the best films of 1927 & 1928 were honored by the Academy
of Motion Production and Sciences, or the AMPS.
Emil Jennings became the best actor, and Janet Gaynor the best actress.
Special Award went to Charlie Chaplin for his contribution to the
silent movie era and for his silent film ‘The Circus’.
While Warren Brothers was commended for making the first talking picture ‘The Jazz Singer’, - also receiving a Special Award!
Now, the origin of the term ‘OSCAR’ has remained disputed.
The Academy adopted this name from 1939 onwards it is stated.
OSCAR award has now become “the stuff dreams are made of”!
It is a gold-plated statuette of a knight 13.5 inches in height, weighing 8.5 pounds, was designed by MGM’s art director Cedric Gibbons.
Annually awarded for honouring and encouraging excellence in all
facets of motion picture production.

Movies During the Great Depression Era (1929-1941):
Musicals and dance movies starring Fred Astaire and Ginger Rogers provided escapism and good entertainment during this age.
“Ginger Rogers did everything Fred Astaire did. She just did it
backwards and in high heels,” - the Critics had said.
This compatible pair entertained the viewers for almost one and
a half decade.
During the ‘30s, gangster movies were popular starring James Cagey, Humphrey Bogart, and Edward G. Robinson.
While family movies had their popular child artist Shirley Temple.
Swashbuckler films of the Golden Age saw the sword fighting scenes of Douglas Fairbanks and Errol Flynn.
Flynn got idolized playing ‘Robin Hood’, this film got released in
1938 on the big screen!
Story of the American Civil War got presented in the epic ‘Gone With The Wind’ (1939) with Clarke Gable and Vivian Leigh.
This movie received 8 Oscars including the award for the Best Film, - creating a landmark in motion picture’s history!
More serious movies like John Steinbeck’s ‘Grapes of Wrath’ and
John Ford’s  ‘How Green Was My Valley’, were released in 1940 and 1941 respectively.
While the viewers escaped that depressive age to the magical world
of  ‘Wizard of Oz’ with its actress Judy Garland most eagerly!
Let us not forget John Wayne the King of the Westerns, who began
his acting career in the 1930s with his movie ‘The Big Trail’;
He went on to complete 84 films before his career came to an end.
Beginning of the 40s also saw Bob Hope and the crooner Bing Crosby, who entertained the public and also the fighting troops.
For the Second World War (1939-45) had interrupted the Golden Age of Hollywood.
When actors like Henry Fonda, Clarke Gable, James Stewart and
Douglas Fairbanks joined the armed forces temporarily leaving
Hollywood.
Few propaganda movies supporting the war efforts were also made.
While landmark movies like ‘Philadelphia Story’, ‘Casablanca’, ‘Citizen Kane’,
‘The Best Years of Our Lives’, were some of the most successful movies of that decade.  (The 1940s)
Now I come towards the end of my Hollywood Story with the decade  of the 1950s, thereby extending the period of Hollywood’s Golden Age.
Since having past the Great Depression and the Second World War,  the Hollywood movie industry truly matured and came of age.

                        HOLLYWOOD  OF  THE  1950s

BACKGROU­ND:
The decade of the ‘50s was known for its post-war affluence and
choice of leisure time activities.
It was a decade of middle-class values, fast-food restaurants, and
drive-in- movies;
Of ‘baby-boom’, all-electric home, the first credit cards, and new fast moving cars like the Ford, Plymouth, Buick, Hudson, and Chevrolet.
But not forgetting the white racist terrorism in the Southern States!
This era saw the beginning of Cold War, with Eisenhower
succeeding Harry S. Truman as the American President.
But for the film industry, most importantly, what really mattered  
was the advent of the Domestic TV.
When the older viewers preferred to stay at home instead of going
out to the movies.
By 1950, 10.5 million US homes had a television set, and on the
30th December 1953, the first Color TV went on sale!
Film industries used techniques such as Cinemascope, Vista Vision,
and gimmicks like 3-D techniques,
To get back their former movie audience back on their seats!
However, the big scene spectacle films did retain its charm and
fantasy.
Since fantasy epics like ‘The Story of Robin Hood’, and Biblical epics like ‘The Robe’, ‘Quo Vadis’, ‘The Ten Commandments’ and ‘Ben-Hur’, did retain its big screen visual appeal.
‘The Robe’ released on 16th September 1953, was the first film shot
and projected in Cinema Scope;
In which special lenses were used to compress a wide image into a
standard frame and then expanded it again during projection;
Resulting in an image almost two and a half times as high and also as wide, - captivating the viewers imagination!

DEMAND FOR NEW THEMES DURING THE 1950s :
The idealized portrayal of men and women since the Second World War,
Now failed to satisfy the youth who sought exciting symbols for rebellion.
So Hollywood responded with anti-heroes with stars like James Dean, Marlon Brando, and Paul Newman.
They replaced conventional actors like Tyron Power, Van Johnson, and Robert Taylor to a great extent, to meet the requirement of the age.
Anti-heroines included Ava Gardner, Kim Novak, and Marilyn Monroe with her vibrant *** appeal;
She provided excitement for the new generation with a change of scene.
Themes of rebellion against established authority was present in many Rock and Roll songs,
Including the 1954 Bill Hailey and His Comets’ ‘Rock Around the Clock’.
The era also saw rise to stardom of Elvis Presley the teen heartthrob.
Meeting the youthful aspirations with his songs like ‘Jailhouse Rock’!
I recall the lyrics of this 1957 film ‘Jailhouse Rock’ of my school days, which had featured the youth icon Elvis:
   “The Warden threw a party in the county jail,
     The prison band was there and they began to wail.
     The band was jumping and the joint began to sing,
     You should’ve heard them knocked-out jail bird sing.
     Let’s rock, everybody in the whole cell block……………
     Spider Murphy played the tenor saxophone,
     Little Joe was blowing the slide trombone.
     The drummer boy from Illinois went crash, boom, bang!
     The whole rhythm section was the Purple Gang,
      Let's rock,.................... (Lyrics of the song.)

Rock and Roll music began to tear down color barriers, and Afro-
American musicians like Chuck Berry and Little Richard became
very popular!
Now I must caution my readers that thousands of feature films got  released during this eventful decade in Hollywood.
To cover them all within this limited space becomes an impossible
task, which may kindly be understood !
However, I shall try to do so in a summarized form as best as I could.

BOX OFFICE HITS YEAR-WISE FROM 1950 To 1959 :
Top Ten Year-Wise hit films chronologically are: Cinderella (1950),
Quo Vadis, The Greatest Show on Earth, Peter Pan, Rear Window,
Lady and the *****, Ten Commandments, Bridge on the River
Kwai, South Pacific, and Ben-Hur of 1959.

However Taking The Entire Decade Of 1950s Collectively,
The Top Films Get Rated As Follows Respectively:
The Ten Commandments, followed by Lady and the *****, Peter Pan, Sleeping Beauty, Bridge on the River Kwai, Around the World in Eighty Days, This is Cinerama, The Greatest Show on Earth, Rear Window, South Pacific, The Robe, Giant, Seven Wonders of the World, White Christmas, Twenty Thousand Leagues Under the Sea, Sayonara, Demetrius and the Gladiator, Peyton Place, Some Like It Hot, Quo Vadis, and Auntie Mame.

Film Debuts By Rising Stars During The 1950s :
The decade of the ‘50s saw a number of famous film stars making
their first appearance.
There was Peter Sellers in ‘The Black Rose’, Marlon Brando in
‘The Men’, and actress Sophia Loren in ‘Toto Tarzan’.
Following year saw Charles Bronson in ‘You Are in the Navy Now’,
Audrey Hepburn in ‘Our Wild Oats’, and Grace Kelly, the future
Princess of Monaco, in her first film ‘Fourteen Hours’. (1951)
While **** Brigitte Bardot appeared in 1952 movie ‘Crazy for Love’; and 1953 saw Steve Mc Queen in ‘******* The Run’.
Jack Lemon, Paul Newman, and Omar Sharif featured in films
during 1954.
The following year saw Clint Eastwood, Shirley Mc Lean, Walter
Matthau, and Jane Mansfield, all of whom the audience adored.
The British actor Michael Cain appeared in 1956; also Elvis Presley
the youth icon in ‘Love Me Tender’ and as the future Rock and Roll
King!
In 1957 came Sean Connery, followed by Jack Nicholson, Christopher Plummer, and Vanessa Redgrave.
While the closing decade of the ‘50s saw James Coburn, along with
director, script writer, and producer Steven Spielberg, make their
debut appearance.

Deaths During The 1950s: This decade also saw the death of actors
like Humphrey Bogart, Tyron Power and Errol Flynn.
Including the death of producer and director of epic movies the
renowned Cecil B. De Mille!
Though I have conclude the Golden Age of Hollywood with the 50’s Decade,
The glitz and glamour of its Oscar Awards continue even to this day.
With its red carpet and lighted marquee appeal and fashion display!

CONTINUING THE HOLLYWOOD STORY WITH FEW TITBITS :

The British film director Alfred Hitchcock who came to
Hollywood later;
Between 1940 and 1947, made great thrillers like 'Rebecca', ‘Notorious’, ‘Rear Window’, and ‘Dial M for ******’.
But he never won an Oscar as a Director!

THE GOLDEN GLOBE AWARD:
This award began in 1944 by the Foreign Correspondence Association at
the 20th Century Fox Studio.
To award critically acclaimed films and television shows, by awarding a
Scroll initially.
Later a Golden Globe was made on a pedestal, with a film strip around it.
In 1955 the Cecil B. De Mille Award was created, with De Mille as its first
recipient.

THE GRAMMY AWARD:
In 1959 The National Academy of Recording and Sciences sponsored the
First Grammy Award for music recorded during 1958.
When Frank Sinatra won for his album cover ‘Only The Lonely’, but he
did not sing.
Among the 28 other categories there was Ella Fitzgerald, and Count Basie
for his musical Dance Band Performance.
There was Kingston Trio’s song ‘Tom Dooly’, and the ‘Chipmunk Song’,
which brings back nostalgic memories of my school days!

CONCLUDING HOLLYWOOD STORY  WITH STUDIOS OF THE 1950s

Challenge Faced by the Movie Industry:
Now the challenge before the Movie Industry was how to adjust to the
rapidly changing conditions created by the growing TV Industry.
Resulting in loss of revenue, with viewers getting addicted to
their Domestic TV screen most conveniently!

The late 1950s saw two studios REPUBLIC and the RKO go out of business!
REPUBLIC from 1935- ‘59 based in Los Angeles, developed the careers of
John Wayne and Roy Rogers, and specializing in the Westerns.
RKO was one of the Big Five Studios of Hollywood along with Paramount,
MGM, 20th Century Fox, and Warner Brothers in those days.

RKO Studio which begun with Fred Astaire and Ginger Rogers in the ‘30s,
included actress Katherine Hepburn who holds the record for four Oscars
even to this day;
And later had Robert Mitchum and Carry Grant under an agreement.
But in 1948, RKO Studio came under the control Howard Hughes the
temperamental Industrialist.
Soon the scandal drive and litigation prone RKO Studio closed, while
other Big Four Studios had managed to remain afloat!


PARAMOUNT STUDIO:
Paramount Studio split into two separate companies in 1950.
Its Theatre chain later merged with ABC Radio & Television Network;
And they created an independent Production/Distribution Network.
Bing Crosby and Bob Hope had been Paramount’s two biggest stars.
Followed by actors like Alan Ladd, William Holden, Jerry Lewis, Dean
Martin, Charlton Heston, and Dorothy Lamour.
They also had the producer/director Cecil B. De Mille producing high-
grossing Epics like ‘Samson & Delilah’ and ‘The Ten Commandments’.
Also the movie maker Hal Wallis, who discovered Burt Lancaster and
Elvis Presley - two great talents!

20th CENTURY FOX:
Cinema Scope became FOX’s most successful technological innovation
with its hit film ‘The Robe’. (1953)
Its Darryl Zanuck had observed during the early ‘50s, that audience  
were more interested in escapist entertainments mainly.
So he turned to FOX to musicals, comedies, and adventure stories.
Biggest stars of FOX were Gregory Peck & Susan Hayward; also
stars like Victor Mature, Anne Baxter, and Richard Wind Mark.
Not forgetting Marilyn Monroe in her Cinema Scope Box Office hit
movie - ‘How to Marry a Millionaire’, which was also shown on
prime time TV, as a romantic comedy film of 1953.

WARREN BROTHERS:
During 1950 the studio was mainly a family managed company with
three brothers Harry, Albert, and Jack Warren.
To meet the challenges of that period, Warren Bros. released most of
its actors like James Cagney, Humphrey Bogart, Oliver de Havilland, -
Along with few others from their long-term contractual commitments;
Retaining only Errol Flynn, and Ronald Regan who went on to become
the future President.
Like 20th Century Fox, Warren Bros switched to musicals, comedies,
and adventure movies, with Doris Day as its biggest musical star.
The studio also entered into short term agreements with Gary Copper,
John Wayne, Gregory Peck, Patricia Neal, and Random Scott.
Warren Bros also became the first major studio to invest in 3-D
production of films, scoring a big hit with its 3-D  suspense thriller
‘House of Wax’ in 1953.

MINOR STUDIOS were mainly three, - United Artists, Columbia, and
The Universal.
They did not own any theatre chain, and specialized in low-budgeted
‘B’ Movies those days.
Now to cut a long story short it must be said, that Hollywood finally
did participate in the evolution of Television industry, which led to
their integration eventually.
Though strategies involving hardware development and ownership of
broadcast outlets remained unsuccessful unfortunately.
However, Hollywood did succeed through program supply like prime-
time series, and made-for-TV films for the growing TV market making
things more colorful!
Thus it could be said that the TV industry provided the film industry
with new opportunities,  laying the groundwork for its diversification
and concentration;
That characterized the entertainment industry during the latter half  
of our previous century.
I must now confess that I have not visited the movie theatre over the last
two decades!
I watch movies on my big screen TV and my Computer screen these days.
Old classical movies are all available on ‘You Tube’ for me, and I can watch
them any time whenever I am free!
Thanks for reading patiently, - Raj Nandy.

In this chapter, the researcher reviewed the opinion of some past and recent writers on the subject and also added their own ideal under the following sub-headings:
- Conceptual frame work
- Theoretical frame work
- Empirical frame work
- Summary

2.1. CONCEPTUAL FRAME WORK
CONCEPT OF ZOOLOGICAL GARDEN

The concept zoological garden is a form of ex – situ conservation, which primarily involves keeping of animals alive outside their natural environment for aesthetic educational researches and recreational purpose (Varadharajan and Pythol 2000). Nigeria is blessed with abundant wildlife species which needs to be properly managed in a sustainable basis to prevent depletion (Opara et –al 2010). Hence the need to adapt strict management of resources, repopulation of endangered species and conservation of wildlife park and zoological garden and management strategies (Ajebede et – al 2010).
Throughout history, human have given value to other species of animals as means of entertainment, education and spirituality in addition to being source of food and clothing (front 2011, 69) collecting and exhibiting and exhibiting animals originated from Ancient Egypt where private collection were reserved for the higher class population as a symbol of wealth and power (wearing and jobberns 2011, 19 – 50). In the 1900’s, zoo’s based themselves as conservation movement, with focus on scientific study of endangered species. In the beginning of the 20th century, zoo became an attraction of mass audiences (Beardworth and Bryan 2001, 88). By the late 1900’s there was a shift in the natural of zoo with public attitude and interest changing nature and conservation, with concern for ecosystem and awareness as they protect endangered species (Wearing and Jobbern 2011, 50.

ROLES OF ZOOLOGICAL GARDEN
(Mason 2011, 189) reveal that the roles of zoo are:
a. Educating people about animals.
b. Conservation of endangered species
c. Safeguarding the welfare visitors
d. To generate revenue
e. Providing visitors facilities such as catering and merchandising
f. Re – introducing captive breeding into the wild and carrying out zoological and veterinary research to improve animal welfare in the wild and in captivity.
On the other hand, zoos served as scientific research, for example, zoologist learn more about animals habit and diseases by studying them in zoos studies of animals living kin zoo, together with examination of those that have died have provide zoologist with information about the structure and function of animal bodies (Usher M.B 2000). Keeping wildlife animals in captivity bring visitors from different parts of the world for different purposes such as to provide sources of recreation in the city, to provide biological specimen to constitutes, a learning resource for secondary school, colleges, and universities. It also provide employment and game reserve, provides sources of protein revenue, esthetics recreation, education and scientific values (Presley 2001). The captive animal propagation is one way of encouraging growth of depleted wildlife species population and so properly planned program of zoo establishment and development is considered as one of effective method for conservation of wildlife (Okpiri 2005). Educational environment study and conservation of the  environment have become a subject of major importance all over the world, not only from the point of view of preventing population, but also from the point of conserving water supplies by protecting water shed, conserving soil, vegetarian and Fauna. (Comphell 2007). Comphell also stated that conservation zoos can provide an important facility for research at both pure and applied levels in both the field and laboratory in colleges and universities. Bigot (2000) emphasized that the primary function of zoo curators is to make visit a leaving experience. The attention and effort given to wildlife conservation and tourism in both state and federal levels have been noted.

CONCEPT OF TOURISM
According to UNWTO 2020 defined as the study of man away from his usual habitat. Activities of a person traveling to and staying in places outside their usual environment for not more than one consecutive year for leisure, business and other purposes, tourism contributes to specie conservation, communities project in developing countries like: Nigeria, environmental education, awareness and economies development (Klutzy, 2000). Filton et al (2000) reported that 20 – 40 percent of international tourism is related to wildlife. In Nigeria, tourism contributed 3.3 percent of total GDP in 2011 with forecast of a 10.8 percent increase for 2012 (WTTC 2012). Smith et al (2012) recognized the role of wildlife tourism as building breeding species management and influencing visitor’s behavior for the benefit of wild animals. Fibs (2007) underscored the value of zoo visitors and their feedbacks for the planning and designing of zoo and more importantly to decision making in zoo management by showing on – going treads. He therefore stands to reason that visitors’ preferences should be seriously considered by policy makers and management of zoo and other similar institutions. An area in which visitors’ preference is highly important for a zoo in particular is choice of animals desired. Woods (2000) observed that humans have definite preference for different species of animals. Knowledge of visitors desires in terms of animals and the features that make the animals appealing will assist zoo management in animal acquisition and also in development of education and interpretation programs listening physical features, behavioral characteristics as factors influencing animals preference (Wood 2000, Wentworth 2012). Wild tourism can be described as tourism undertaken to view and or encounter non – domesticated animals in captive, semi – captive or in their natural environment (CRC 2001, Newsome et al 2005). According to Durbary (2004), it could be non consumptive such as viewing, photographing and fishing.

CONCEPT OF ZOO AND EDUCATION
In zoo and education, a study by Patricia et al 2007 states that conservation and education are key elements in the mission statement of zoos. A survey conducted by the Association of zoo and aquarium (AZA) reveals that the general public rate conservation and education as the most important role of zoo (Frasers and Stickler 2008). Zoo primarily deals with three aspects of conservation practice i.e practice, advocacy and research. Conservation practice entails captive breeding, species rein-introduction programs, species survival plans and the use of zoo revenue for conservation programs in wild. Conservation advocacy include: public engagement, promoting awareness, advocacy, stewarding and fund raising events and schemes, a good example of which is like “Adopt animal scheme at most modern zoos”. Moreover, conservation research is conducted on wildlife biology, population dynamics, animal behavior, health and welfare and there are also publications generated by zoos animals care captivity. The preservation of animals in zoos makes it easier for more people to see them.
As well, zoos have been used to preserve various endangered species. However, zoos have become powerful educational tool for many scholars, biologists and researchers (Falk and Dierking 2000).  Individual who visit a zoo get the rare opportunity to examine the relationship between man and animal (Wagoner and Jenson 2010). Students can learn a lot about certain animals that might not be locally available. Many specimen and animals (Wagner and Jensen 2010) argue that zoo makes it possible for researchers to conduct their studies, for instance, researchers can use caged animals to make various observation about wildlife or animals. The acquired knowledge can be used to support the survival of the wild animals in their natural habitats. It is therefore agreeable that zoos have an important educational role in every society. This because, learning is ever – changing process (Falk and Dierking 2000). In the 1970’s the primary educational target for most American zoo was elementary level children. The idea was that building understanding would lead to appreciation which would eventually produce a generation that was concerned about wildlife and the environment (Wheatly 2000). Wheatly emphasized that although children are still a primary audience, zoos are extending themselves to reach many others audience that can make difference in action today. This initiative includes the membership, governance and employee of zoo.

CONCEPT OF ZOO AND CONSERVATION
In zoo and conservation, according to Max – Planck Gesell Chaft (2011), Zoology garden breeds animal from threatened populations and and thus makes greater contributions towards biodiversity conservation. According to UN (2020) on global biodiversity warned that 1 million species are at risk of extinction with decades, putting the world’s natural life support system in jeopardy. Unfortunately, loss of plants and animals habitat leads to from species extinctions and loss of diversity from ecosystem. Fortunately, not all of the extinctions occur at once. Conservation action may still be able to save threatened species (John M et al 2016). At October 2010, meeting of the Convention on Biological Diversity (CBD) in Nagoya, Japan, delegates discussed a plan to reduce pressure in the planet’s biodiversity. Key targets include expanding coverage of protected areas, halving the rate of loss of natural habitats, and preventing extinction of threatened species. Species whose habitat is severely threatened, however, the outlook is so bleak that the International Union for Conservation of Nature (IUCN), the US Endangered Species Act and the CBD (Article a) recognize that In-Situ conservation action (ie, in the species natural habitat) will need to be combined with Ex-Situ approaches, such as captive breeding in zoos, aquariums and so on (Conde et al 2011).

THE THEORETICAL FRAME WORK
The animal welfare and management (Dakin 2001) is a state of being that can be measured, recognized that its ranges from very poor to very good, introduces the concept of coping, allow measurement separate from moral consideration and refer to feeling as well as physical and psychological health. The definition of welfare that we use also emphasizes that it relates to an individual and thus welfare can differ between different members of the same species, even when exposed to the same condition (Horsey et al 2009). In the case of zoo animals, which have often come from very heterogeneous background, individuals may vary greatly in this previous life experiences and this can influence their ability to cope with certain challenges, by using each animal as its environment and thus an individual’s welfare can be measured.
There are also some species – specific characteristics that have evolved to enable animals cope with different, environment and thus we should also consider welfare at the species level; such species level adaptation could relate to dietary needs, hearing sensitivity, thermo-regulatory needs and so on. The theory of evolution by natural selection, first formulated in Darwin’s book “On the origin of species” in 1859, this theory states Organisms change over time as result of changes in heritable physical or behavioral traits. Changes that allow an organism to better adapt to its environment will help it to survive and have more offspring. The physical and behavioral changes that make natural selection possible happen at the level of DNA and gene, such changes are called Mutation. “Mutations are basically the raw materials on which evolution act. Pobiner said, mutation can be caused by random error in DNA replication or repair, or by chemical of radiation damage. According to Chinaka (2019) in the book concept of evolution, Charles Darwin proposed the concept of natural selection as the mechanism of evolution. The main postulates of Darwinism are:
1. Geometric increase: According to Darwinism, the populations tends to multiply geometrically and the reproductive powers of living organism (biotic potential) are much more than required to maintain their numbers.
2. Limited food and space
3. Struggle for existence
4. Variation etc
Both natural animal populations and those in captivity are subject to evolutionary forces. Evolutionary changes to captive populations may be an important, but poorly understood, factor that can affect the sustainability of these populations. The importance of maintaining the evolutionary integrity of zoo populations especially those that are used for conservation efforts including rein-introductions is critical for the conservation of biodiversity.
Greater appreciation for an evolutionary perspective may offer important insights that can enhance the reproductive success and health examples and associated strategies that highlight this approach, including minimizing domestication (ie genetic adaptation to captivity), integrating natural mating systems into captive breeding protocols, minimizing the effects of translocation on variation in photoperiods and understanding the interplay of parasites and pathogens and inflammation. Captive populations can adapt rapidly to captive environments through demonstration, in which human impose artificial selection in order to increase the prevalence of desired traits in the domesticated population.
For domestic animals, human breeders choose to breed only those individuals that thrive in the captive environments, leading to trans-generational changes that result in a population that is adapted to breed and survive in the conditions imposed by the breeders. Among captive population of animals, zoo populations are unique in that they are maintained to educate the public regarding wildlife and their habitat or to preserve critically endangered species through captive breeding and reinforcement program. Although assessment and preservation of genetic diversity is a top priority for most conservation breeding programs, fundamental to these goals is the maintenance of the genetic variation of these captive populations (Lacy 2009). Whether used to further educational or conservation goals, it is critically that these captive population are representative of the natural populations from which they are desired (Ashley et al 2003). However, maintaining captive population, such that they are reflective of the wild phenotype of the animals, can be challenging in zoos because of the mismatch the environments that the zoo population is originally from and the captive content in which they are been housed. Hendry et al 2015 carol et al 2014, for example, solitary animals with large territories that only encounter sexually mature counterparts during estrus may be housed in proximity of their mate year round, potentially leading to the behavioral issues, including ****** aggregation or ****** incompatibility. Other stressor can exist in captive environments for which animals are not adapted, including the acoustic environments, physical substrate and even availability of food (Morgan and Tromborg 2007). Minimizing the mismatch between the natural environment and the captive environment and they should limit the decline and poor performance of captive populations (Hendry et al 2011; Carrol et al 2014). Captive environments are very different from the wild and can impose different selection pressures that can lead to genetic adaptation in the captivity that affects behaviors (eg: temperaments; MC Douglas et al 2006), morphology (eg; size, skeletal morph metric O’ Regan and Kitchener 2005); and reproductive output (eg; age at ****** maturity, letter size). In particular populations of species with short generation times will adapt more rapidly to captivity than those with long generation time (Frankham 2008).
Social learning theory is the idea that children from observing. According to the learning theory, learning is based on social interaction with the environments (Nwamuo et al 2006). As children walk around the zoo, they are exposed to words and concepts. It also encourages dialogue between parents, siblings, friends and zoo guards (Jessica 2014)  visiting the zoo help the children and other visitors to understand the importance of taking care of the environments as it has a significant impact on lives and welfare of animals and importance of conservation and animal care which will never be forgotten. According to (Nwamuo et al 2006) social learning theory plays a big role in how people and especially learn. There are four elements to social learning theory including:
• Attention: Children can’t learn if they aren’t focused on the task. Students who see something unique or different are more likely to focus on it, helping to learn just as in zoo.
• Retention: people learn by internalizing information later when we can recall that information later when we respond to a situation in the same way which we saw.
• Reproduction: in the way we are able to reproduce our previously learn behavior or knowledge when it’s required. Practicing our response in our head or in action can improve the way we response.
• Motivation

Operant conditioning of behaviors theory of B.F Skinner, enclosure design and environmental enrichment strategies have all been suggested to improve the welfare of zoo animals by reducing stereotypical behavior and rein-introduction success of wildlife species. (WAZA 2015). Thus, the use of these strategies has important consequences for zoological collections. Despite the recognition and wild-scale implementation of such strategies, however, concerns around global zoo animal welfare remain and behavioral pathologies are common in many species. (Luhrs 2010) using operant conditioning, some of the barriers to delivering positive welfare experiences through holistic behavioral management strategies to zoo animals and make recommendations for institutional approaches towards improving zoo animal welfare using examples of Abnormal Repetitive Behaviors (ARBs) through targeted behavioral management.

EMPIRICAL FRAMEWORK
According to P.A Anadu (2000) on his study wildlife conservation in Nigeria: problems and strategy a case study of wildlife reserve of University of Benin, the major treats to nature conservation in Nigeria and he reviewed critically the measures adopted for the protection of wildlife. According the study, the major problem includes habitat degradation (through uncontrolled logging, agricultural projects, industrial plantations, highway and urban development’s and exploitation for fuel wood) over hunting and poaching.
He suggested that to protect wildlife include the creation of more game reserve, enactment of wildlife laws, signing of international treaties and manpower development. According to his research through interview with about 10 workers or staff of the wildlife reserve, the major treats to the area include poaching and hunting, indiscriminate feeling of forest trees, low funding, inadequate game laws and weak enforcement of the existing legal provisions.
It is suggested that the Federal Government should intervene more positively in favor of conservation by creating more national parks and assuming joint responsibility with the states for formulating wildlife laws. Furthermore, the role of nongovernmental organizations in influencing conservation policies and mobilizing public opinion will be cruial in different years ahead.
In the journal “A synopsis of wildlife conservation in Nigeria by Timothy A Afolaya  2009, this article emphasized the recent developments in the overall conservation program in Nigeria as it describes the important role which wildlife is playing in helping to feed the nation, in creating employment opportunities, in education in research, in recreation and in local medicine. Inadequately of Nigerian wildlife legislation and of the trained manpower to protect and manage the wildlife resources are among the crucial wildlife management problems identified. It is also stressed that the basic information for effective management is often lacking where Nigerian wildlife reserved are concerned. It also stressed that the main problems facing wildlife conservation in Nigeria include poaching, over exploitation, lack accurate data, bush burning that destroys wildlife habitat. There is adequate reliable database to facilitate forestry planning and development. Weak forest policy and implementation, forest policies lacks legal backing and hence its enforcement is difficult. The Nigeria forestry policy Act, 1937 is subsumed in the National Agricultural Policy of 1988. Forest tariffs are relatively low and are not revised frequently penalties under most laws are low and seldom enforced. It suggested that Nigeria forestry policy act should be reviewed or renew and encourage the government to implement the policies adequately and enforce penalties on the offenders.
Jonathan (2009) in his own study animal wildlife conservation under multiple land use system in Nigeria reveals that out of 6 selected zoological garden and game reserves in six geopolitical zones in Nigeria. The situation of wildlife in Nigeria is nevertheless different. Except in the Yankari, upper Ogun and Kwiabaha, Game Reserves and the Kainji lake National park, little efforts have been made to protect the Nigerian animal wildlife resources from human pressure and wide spread extinction. To many, what remains of the wildlife animals are best seen in the few state owned zoological gardens in Nigeria?
However, because most indigenous large animal species including Elephant, Buffalo, Chimpanzee, Gorilla, Rhinoceros, Leopard and Ostrich have not been able to reproduce in the various zoological garden so far, the hope to conserve this animals are brittle.
According to his work, animal wildlife is a declining resource in Nigeria because of unplanned land use practices. For example, land uses in game reserves are often conflicting and contradictory for land uses, timber extraction, hunting; food crop production and settlement are simultaneously going on in game reserves with little or no control measures and with no management plans. The excessive demands for land these conflicting uses have greatly disturbed the ecosystems involved, thus making the survival of the wild animals uncertain. Specially, the problems of wildlife conservation in Nigeria are:
a. Poaching
b. Indiscriminate burning of the vegetations
c. Uncontrolled grazing activities in the reserves
d. Intensive logging for domestic and industrial uses
e. Users rights on the reserves enjoyed by the traditional owners of the land before reservation
f. Lack of adequate fund to manage the reserve
g. Ineffective legislation
h. Lack of trained manpower
i. Urban sprawl
j. Infrastructural development of roads, electric and telegram lines and irrigation schemes.
k. Lack of modern enclosure or caging
l. Inability of animals to breed within the captive environment.

He then emphasized that the picture for Nigerian animal wildlife depends on the nation’s ability to conserve what is left either in their natural habitat or at least, in zoological gardens. The game reserve should be reduced to manageable numbers while state governments should win public sympathy through adequate conservation publicity and the provision of sufficient vehicles and personnel to manage the game reserves. The policy of land use in game reserves should be conducted on:
a. The number and species of animals hunted per year
b. The population of animals species in the game reserves and their habitat sustainability
c. The endangered and extinct animals species and specific reasons for the decline in their population
d. Human problems peculiar to each reserve and ways of minimizing them.
e. Establishment of rein-introduction programs.

SUMMARY
The establishment of zoos in a society is premised partly on the idea of bringing man close to wild animal’s species (Yager et al 2015). This establishment has various roles to play in the ecosystem and all endeavors of life. The role of zoological garden as well as wildlife conservation is as follows:
1. Education: zoos are established for the preservation of animal to make it easier for more people to see them and learn their characteristics and habitat. Zoo animals are used for specimens both for secondary schools students and tertiary institution as well as teaching the public the benefit of wildlife. A survey conducted by the Association of Zoos and Aquarium (AZA) reveals that, the general public rate conservation and education as the most important role of zoo (Fraser and Stickler 2008).
2. Conservation: of endangered species to avoid extinction of such animal.
3. Tourism:  it serves as a centre of tourism as people from different parts of the country visit to learn about nature at their leisure.
4. Generating revenue for the government as well as provides employment opportunities individuals etc
Most problems encountered in Nigerian zoos include:
• Poaching
• In availability of breeding species
• Lack of trained personnel’s
• Lack of fund by the Government
• Lack of infrastructure and conservation facilities.
