After reading "Is Humanity Suicidal" I decided to draw a poster that promotes the growth of trees. People are clear cutting forest left and right. This affects not only the animals that live there, but ti affects humans too. Without trees, what other way can we reduce atmospheric carbon dioxide? Every day we are burning fossil fuels, and therefore putting CO2 into the air. This CO2 breaksdown the ozone layer. If people plant trees, we will have a natural way to reduce at lease SOME of the CO2 in the atmosphere.
