Great Green Wall (Africa)

The Great Green Wall is a big project happening in Africa. People are planting a long line of trees and vegetation to create a kind of wall. This wall is stretching all the way across the continent of Africa and is specially designed to help make Africa a better place to live. The trees will help to stop sand dunes and desert from growing, and they'll also help to make more rain fall in areas that are too dry. The plants in the green wall will also provide food and other resources for people living in Africa.
