Why Worry about How Many Species and Their Loss?

Robert M May

Working Papers from eSocialSciences

Abstract: We are astonishingly ignorant about how many species are alive on earth today, and even more ignorant about how many we can lose yet still maintain ecosystem services that humanity ultimately depends upon. The paper is important in offering an imaginative new approach to assessing total species numbers, both on land and in the sea. URL:[http://www.plosbiology.org/article/browseIssue.action].
