The Sixth Extinction (2002)
Throughout the history of evolution, five great catastrophes have affected the earth’s surface. Each caused massive die-offs, with many species going extinct and, after each of them, life had to re-organize itself around the surviving species.
Today, 27,000 species disappear each year, a figure that equals or exceeds the rate of die-offs that devastated the earth during the previous extinction processes. Are we facing the sixth extinction? Are human beings responsible for this ecological disaster?
