For several years, chocolate barons have devastated forests to make room to plant cocoa, a crop that naturally grows in shade. Now, a report from Mighty Earth—a nonprofit that works to conserve threatened landscapes—shows new evidence that illegal deforestation is occurring in protected areas; specifically, in the national parks of West Africa.

The Ivory Coast and Ghana produce a combined 2.6 million tons of chocolate—60 percent of the world's supply. It's no wonder so many of these nations' protected lands are at risk. According to Mighty Earth's report, 10 percent of Ghana's tree cover has been replaced by cocoa monocultures. The Ivory Coast, once heavily forested and extremely biodiverse, has lost seven of its 23 protected areas to cocoa. Due to habitat loss, its chimpanzees are now endangered, and its elephants are nearly extinct. This means that companies like Mars, Nestlé, Hersey's and Godiva are on the hot seat for making products using cocoa grown by uncertified sources.
