E. O. Wilson of Harvard, the world’s most esteemed biologist, estimates that one half of all species on earth will be extinct by the end of this century.
Unknown to most humans, we are currently undergoing the largest mass extinction of species since the extinction of the dinosaurs 65 million years ago.
The current mass extinction is occuring at a faster rate than any of the previous 5 mass extinctions in the earth’s history.
Mass extinction is not as simple a problem as “There won’t be any wild animals left.” The earth is an interconnected system in which each species and ecosystem depends on many others. Climate, atmosphere, land, and agriculture are also highly dependent on living organisms.
