I am at #NatureNow in New York and have just been challenged by twins Kaitlin and Lauren Grierson to plant 1000 trees for every young person in Gabon. I already had a plan to plant a tree for every one of our 2 million citizens. Now I am being challenged to plant a billion! pic.twitter.com/R1VFpiIi0S
