Not just trees

Picture
 You probably didn't know that most of the oxygen in our atmosphere doesn't even come from trees. It comes from offshore plankton blooms. Every spring phytoplankton (plant plankton)  zoo  plankton (animal plankton, like hatched eggs) release literary tons of oxygen into the air. That is why spring air smells a certain way, it has more oxygen than any other season. And it also give the ocean varying shades. Darker or lighter green and in some parts of the ocean it leaves red pathways along the currents. That doesn't mean trees aren't important. In fact they provide most of the fall and winter oxygen, without them and other plants we would probably be breathing air that would be thin like it is at the top of mountains. So take care of forests and the ocean because without them we would only have carbon dioxide.
