Title: 30% solution is neither necessary nor sufficient 

Speaker:Stuart Pimm  Duke University

Summary  

At COP 15, nations considered the aspirations for the next decade in terms of stemming the loss of biodiversity. The problem is easy to state: human actions are driving species to extinction 1000 times faster than species originate. Will expanding protected areas from the current 17% of the land surface to 30% help? Current protected areas are predominantly in cold, hot, or remote places, but surprisingly enough are in the right places. They protect the ranges of the most vulnerable species better than one might expect by chance globally and in China. Expanding protected areas into more wilderness will not greatly benefit biodiversity. The details matter — we need quality, not quantity. For some places, such as the Amazon, much more than 30% will be needed. Moreover, existing protected areas are fragmented and aspirations to restore nature must reconnect those fragments — the point of what Saving Nature does.
