This photo is explaining about how people destroy trees, but if the trees were not cut down, they would provide more than just paper. Trees produce oxygen, which humans and any animal, need. Trees will also make the water clean, using the evaporation system. Without trees or plants, we would have no clean water, and we would die. This picture us telling people vaguely about how trees help communities and the overall Earth if they are not chopped down, and made into paper or aspirin.
