This fascinating and sometimes devastating book chronicles the previous mass extinction events that have occurred on our planet, and the modern, man-made one we find ourselves in the middle of right now. Through interviews with scientists, researchers, and explorers, the author conveys the changes that are occurring to our planet’s ecosystem while keeping the prose simple and understandable for the general reader. If you have an interest in conservation, or are simply curious about the ecological history of our planet, I highly recommend this page turner of a book.
