"Hopeful": Historic U.N. High Seas Treaty Will Protect 30% of World's Oceans from Biodiversity Loss

The first-ever international treaty to protect the oceans was agreed to by negotiators from more than 190 countries at a United Nations conference this weekend, capping nearly two decades of efforts by conservation groups. The legally binding pact could help reverse marine biodiversity loss by establishing marine protected areas covering nearly a third of the world's seas by 2030. We hear more from one of the treaty's scientist-negotiators, Minna Epps, a marine biologist and director of the Ocean Team at the International Union for the Conservation of Nature.
