The most sci-fi moonshot project going on right now isn’t the hyperloop—it’s the Great Green Wall. They are literally fighting a battle to hold back the desert with a gigantic created forest that cuts all the way across Africa. It’s like the Wall in Game of Thrones, but with heat and not cold. The African Union has been building it since 2005 (I don’t know how to get across how huge it is) and I love it and will always post news stories about it. Hats off to Senegal particularly.
