Fossilized termite nests in Africa reveal that the insects were the world's oldest farmers, practicing a type of agriculture millions of years before humans came onto the scene.
Deep in their mud mounds, termites are doing mysterious things regarding temperature change.
As climate change encroaches on already arid ecosystems, the threat of drought and eventual desertification is very real. China's north and Sahelian Africa, for instance, have both created "Great Green Walls" of trees and bushes to keep the desert at bay. Now new research suggests that termites, of all things, can also help.
