make many chopsticks. Trees are the Earth's lungs. They breathe in carbon dioxide, a
dangerous gas for humans, and then make oxygen for us to breathe. If we don't have any trees,
our air will have too much carbon dioxide. One of the causes of global warming is too much
carbon dioxide. Besides humans, animals also need trees. One way we can save our planet is
to carry around our own reusable chopsticks. Lots of people are doing this already. Why not
