Barnosky, Anthony D

The author, a paleobiologist, presents the idea that unless we rethink how we generate the power we use to run our global ecosystem, where we get our food, and how we make our money, we could trigger what would be the sixth great extinction on Earth.

Discusses connections between future centuries and the end of the last ice age, covering the fast pace at which plant and animal species are changing and disappearing and the steps humanity can take to try stopping global warming.
