Atmospheric pollution cartoon.
A cartoon about air pollution, showing a person breathing using an oxygen cylinder in which the oxygen is being produced by a tree.
The cartoon is about the importance of preserving trees, other plants and basically all of the natural world, if only for our own good (as in the image). Of course the natural world is important in its own right, with or without us in it!
