There are so many trees around us that it is easy to take them for granted and forget what incredible living things they really are!
Trees have existed for millions of years. They were growing long before humans came along.
So, they know a thing or two about the planet.
Because trees are living things, they breathe. But instead of using oxygen like we do, they take in carbon dioxide and breathe out oxygen!
Carbon dioxide is a poisonous gas, and we produce lots of it. Not only from the breath of billions of people, but also from pollution created by car exhausts, planes and factories.
So we really need trees to help keep the world balanced and cool, and to reduce the greenhouse gases that cause global warming.
Trees help us in lots of other ways too. They provide many fruits and nuts for us to eat.
Also, many medicines are extracted from the bark, leaves and berries of trees.
Trees are good for us!
