Posted in Library, News & Publications, Papers & Publications on 05/10/18

  Originally published by Science Magazine The 1992 Convention on Biological Diversity (CBD) was one of the first international environmental agreements negotiated.

In Defense of Biodiversity


Posted in Library, News & Publications, Papers & Publications on 05/10/18

Originally published by Yale Environment 360 A number of biologists have recently made the argument that extinction is part of evolution and that saving species need not be a conservation priority. But this revisionist thinking shows a lack of understanding of evolution and an ignorance of the natural world. A few years ago, I helped lead a ship-based expedition along south Alaska during which several scientists and noted artists documented and made...

Radical ideas for conservation, and their implications’ raises some important issues for conservation, but it paints a misleading picture of the Nature Needs Half movement.

Protecting Half Is Still Possible


Posted in News & Publications, Papers & Publications on 04/14/17

If habitat conversion continues unabated, key ecosystems could collapse,...
