A big, beautiful wall is currently being built across the entire width of Africa

When we think of walls, we usually think of a structure to keep people and/or animals out or in. But The Great Green Wall being built across Africa has an entirely different purpose.

The Sahel region, along the southern border of the Sahara desert, is one of the poorest regions in the world, and one of the most impacted by climate change so far. Persistent drought and lack of food has created conflicts over resources and forced people to migrate away from the region. The Great Green Wall project is an ambitious attempt to mitigate the environmental and economic effects of climate change in this part of Africa, utilizing nature itself to do so.

The goal is to create a 6000-mile (8000 km) "living wonder" across the entire width of the continent, from Senegal to Djibouti, restoring the degraded land and creating millions of jobs in the process. The project involves planting trees and other vegetation—hence the "green wall"—but its impact goes far beyond adding greenery to the landscape.
