The Great Green Wall of Africa | Atlas Obscura
The Sahara is currently the second largest desert in size, only smaller than Antarctica. However, unlike its frozen relative, the Sahara is actually expanding. The United Nations estimates that, by 2025, two thirds of Africa's arable land will be covered in Saharan sand, vastly expanding the current 9 million square kilometers. Even if these predictions prove aggressive, the effects of farmland destruction on a continent already hard-pressed for food would be devastating on any level.
