Electric vehicles. Carbon-capture devices. Replacing cattle with bison. Lots of ideas have been tossed around for addressing climate change, but a new study suggests that one of the most effective solutions is pretty simple: Just plant more trees—a trillion of them to be exact.
The research, conducted by the Swiss university ETH Zurich, found that around 0.9 billion hectares (roughly 2.2 billion acres) of land is suitable for reforestation around the globe. If it were populated with trees, they could capture about 205 billion metric tons of carbon: That’s two-thirds of all the human-generated carbon emissions released since the Industrial Revolution.
“We all knew that restoring forests could play a part in tackling climate change, but we didn’t really know how big the impact would be,” professor and study co-author Thomas Crowther said in … Read the rest
