Great Green Wall

The Great Green Wall of Africa is a strip of trees being planted across Africa to stop the Sahara desert from moving south. The Sahara desert moving south is affecting countries such as: Niger, Chad, Sudan, Mali and many more. The expansion of desert areas may affect the lives of up to 19 million people, including more than 1 million children. 
The strip of trees is planned to be about 15 kilometers wide. 
Unfortunately some people, when they see these trees, gather wood as timber for them to make fire or other uses.
