Even now, on the very eve of extinction, we continue to move forward with strength, courage and determination to complete the task of annihilation with the almost certain knowledge that our own demise is part of the package.
There are many signs today that we may be in the early stages of a new mass extinction. The climate is changing very rapidly, plus we're seeing an extraordinary number of extinctions among land animals.
Unfortunately for us, earth has experienced at least five mass extinctions during the past 540 million years. Some scientists believe it may be as many as twenty. In other words, mass extinction events are not uncommon.
