So the article says that there are currently about 3 trillion trees, down from about 6 trillion when humans started with agriculture, and then cites an ecologist about how insane this is. But, if you go back even further, wouldn't there be less trees again? I watched the documentary "The Green Planet" a while ago. If I remember correctly, it said that before humans greatly reduced the number of grazing animals in Europe by hunting, the forests in Europe were not dense like today. They were more like parks, with many grassy fields, since obviously many trees did not get the chance to grow tall before being eaten by those grazing animals.
