Natural selection
Survival of the fittest
What morals and ethics
Did our ancestors test?
How did evolution
Make us one of the best?
Psychological development,
Nature and nurture;
They knew what it meant:
We'll evolve further into the future.
But be warned of downfalls on occasion:
A reckless reaction
A spark of destruction
Might eventually be triggered
When human nature
Is more sure of its environment
than it is with itself.

Be warned. This is how world wars began.
