Eleven countries in Africa are building a wall of trees called the Great Green Wall. It stretches across the entire continent from east to west and is being used to fight the effects of climate change. Senegal has planted 11 million trees, making it the country that has made the most progress helping to reverse desertification. The wall is also allowing women to work and get paid. The trees have enabled wells to fill up, allowing vegetable production. School attendance in local schools has also increased as people no longer have to migrate to find work.
