A group of scientists have counted how many trees we have cut down since the dawn of civilization. It turns out we have been quite busy. We have destroyed nearly half of all trees that were originally on earth, that’s 400 trees per person. But all is not lost. One by one we can do our part to replant our missing 400 trees.  Do your part to curb deforestation and breathe easy in the knowledge you have your full set of trees!
