Global Drylands

A vast study of semi-arid ecosystems or dry lands from every continent except Antarctica finds that biodiversity protects the soil and acts as a buffer against climate change. The findings reported in the Journal Science --> http://www.sciencemag.org/content/335/6065/174.summary are important because dry lands currently cover over 40 percent of the Earth’s land surface and support 40 percent of its human population.
