Petrichor
Lured us to the forest floor
No stone left unturned
With hollow throats we yearned
Yet no critter, no creature stirred
Extinction thus had the final word
The Earth is losing animal species at 1,000 to 10,000 times the natural rate, and as many as 30 to 50 percent of the planet's species may be extinct by 2050, the Center for Biological Diversity describes. The natural rate is around one to five species lost each year.
