How the Great Green Wall Is Holding Back the Sahara Desert
The Great Green Wall being built in Africa to halt the southern progress of the Sahara Desert is a favorite public works project of mine — it’s massive, ambitious, long-term, important, and if it works, the effect will repay the cost many times over. This video takes a quick look at some of the work being done on the wall in Senegal.
