More at risk of extinction, but we know how to help

A new report saying one of every five vertebrates (fish excepted) is at some degree of risk also highlights success stories. The authors of the study, led by the United Nations Environment Programme, estimate 18% more species would be at risk without conservation efforts. Success stories include the whooping crane, Przewalski's horse, the California condor, and humpback whale. The best way to help: habitat conservation. It can be expensive, but it does work. As Ana Rodrigues of France's Centre d'Ecologie Fonctionnelle et Evolutive put it, "Conservation is working, there is just not enough of it. Now is the time to scale up conservation."
