Answer three questions and save half the world’s biodiversity

(Wildlife Conservation Society) A growing international movement called ‘Half Earth’ calls for preserving 50 percent of the world’s biodiversity. In today’s Nature News and Views, conservationists James Watson of WCS and the University of Queensland and Oscar Venter of the University of Northern British Columbia pose three questions that need to be answered to make this bold vision a reality. The authors say the answers should provide an effective framework for reaching Half-Earth by 2050.
