Tropical forests face a lot of threats, particularly from the logging and agriculture industries. Their continued disappearance from the face of the Earth is therefore no great news — but new research suggests that they may be disappearing even faster than we thought. And that could have big implications for the global effort against climate change. A new report from the Center for Global Development, released Monday, warns of what will happen if world leaders don’t take stronger steps to cut down on deforestation — that is, if we follow a “business-as-usual” trajectory.
