Mass Extinction: Examining the Current Crisis

Our understanding of mass extinction of our planet's species is right now where our understanding of global climate change was a few years ago: We've amassed just about enough data to document that we are in fact, not just maybe, but well into the sixth great mass extinction in our planet's history; that unlike previous extinction crises, human activities are driving this one; and that it's quite clear what needs to be done to change course but not at all clear that doing so will be enough to prevent the loss of half or more of Earth's species.Andryszewski, Tricia is the author of 'Mass Extinction: Examining the Current Crisis', published 2008 under ISBN 9780822575238 and ISBN 082257523X.
