It’s also the focus of this week’s UN Biodiversity Summit where leaders and environmentalists from nearly 200 countries are meeting in Cali, Columbia to debate ways to reverse the trend and save nature. We speak with Tanya Sanerib International Legal Director with the Center for Biological Diversity.
