The Great Green Wall
You've no doubt heard of the Great Wall of China, but did you know there will someday be another great wall — the Great Green Wall?  If the project is successful, it will be the largest living structure in the world — three times the size of the Great Barrier Reef.  As the name suggests, it will be a wall of trees.  At least that's what it was intended to be.  
 
The idea was to grow a line of trees all the way across Africa in the Sahel region at the southern edge of the Sahara Desert.  According to the original plan, this Great Green Wall would eventually be 10 miles wide and 4,350 miles long, and it would stop or possibly reverse desertification. But things did not go exactly as planned.
 
As anyone might have predicted, many of the trees that were planted died.  In fact, less than 20% of the trees that were planted have survived.  But that doesn't mean the project is a failure.  Over time, local farmers in each area have figured out what works for their particular area.  They have found better ways to conserve and harvest water, and they now protect trees that sprout up naturally.  Now trees are thriving here and there.  Farmers are able to grow other plants in the soil around these trees. 
 
So far, the Great Green Wall is just a patchwork of these small, randomly growing, green areas.  In these patches, the land has come back to life.  This is a welcome change in the Sahel region, which is one of the poorest areas on earth.  It has long suffered from drought and lack of food, and conflicts over dwindling natural resources have caused many people to flee the area.   As these green patches grow, there is more food security and better job security, which means more stability. People in these areas are feeling more optimistic about the future.
