Paper can have a big impact on the environment. It comes from trees, which are like the lungs of the Earth because they give us fresh air. But when trees are cut down and turned into paper, they can't be used to help clean our air anymore. The process of making paper also uses a lot of energy and water, and it creates air pollution, which contributes to climate change. To help protect our environment, it's important to use paper only when necessary and recycle or compost it when we're done.
