For some time we've had our eyes on proposals to build a monumental wall of trees across Africa to hopefully stop or at least slow the Sahara spreading southward. Well, the Great Green Wall has been given the green light. As Mongabay reports, in total about $3.1 billion has been now promised to fund the project.
The plan is to plant a nine mile wide swath of trees crossing from Djibouti in the east, through Ethiopia, Eritrea, Sudan, Chad, Niger, Nigeria, Burkina Faso, Mali, Mauritania, then ending in Senegal. More info on the project: The Guardian
