Darker green areas need more work, light green areas need less work.

It looks like some people have decided to tackle the growing desertification of Africa. I wish them luck. Most all of the information I found on this project is full of useless blather about climate change and social issues. I dunno, maybe that's what it takes to get a project like this moving. Lots of talk about how 'we're all going to work together' and maybe they will. Some places have made some progress.

The idea is to plant a wall of trees 10 miles wide clear across the continent of Africa along the southern border of the Sahara desert. The idea was originally proposed back in the 1950's.

Notice that there are a bunch of rivers below the line of demarcation, the only river above the line is the Nile.
