Conservation International explains how better choices about coffee can protect biodiversity. For years, biodiversity protection was focused on the protection of endangered species. That needs to continue, but it is not enough. Environmental geographers and ecologists also now focus on hotspots -- places that still have a lot of biological diversity, but where land-use change threatens that diversity. It turns out that many of those places produce coffee, and the way the coffee is produced can make a tremendous difference in whether that diversity is protected.
