In the desert, a single tree lay growing, from bulb, to twig, to trunk, to tree. No one had any knowledge of what the tree actually was. Nobody cared. It was the only tree in the universe, out of grass, meadows, parks, woods, there were no trees left. All animals had left to live elsewhere, but there was nowhere to live. They couldn't live in a place without trees, and this lonely desert wasn't good enough. They needed nature, and most of all, trees. Soon this will happen to our world. No trees left. People are chopping them down for no good reason. It is being burned for fun in a fire, when a radiator has been invented. Use what we have lots of, not what we have less of. Learn to control.

The message is
Don't cut down trees. We have resources, and you don't need to take them down.
