When you take in a breath, what happens? If you take a big breath, you can feel air going into your body through your mouth. But why do we breathe? We breathe because our bodies need something in the air called oxygen. Oxygen is like food for our blood. You cant see oxygen, but its there in the air, and people and animals need it to live.

Your body changes oxygen into a different gas called carbon dioxide. Carbon dioxide is what comes out of your body when you breathe out. You breathe in oxygen, and you breathe out carbon dioxide.

Trees and plants dont breathe oxygen as we do. They take in carbon dioxide and they put out oxygen  just the opposite of people and animals. So having lots of plants around is good for people and animals  plants and trees make the oxygen that we need to breathe. Wow...God knew what He was doing indeed. Without this in His design for all living things we could not have survived.
