?It takes a long time ? millions of years ? to create species as fully developed as the ones around us?. We are destroying species a hundred times faster than they could be created, even if we left the natural environment alone. We are doing the equivalent of drawing down hard on our bank account; and you can?t be drawing down on your bank account at a hundred times the rate you?re putting new money in without going broke very fast.?
– E.O. Wilson
