Let’s learn more about it! Our silent friends From the deepest forests to our towns and cities, trees are all around us. We share our world with trees. They are our silent friends, but we often overlook them. In fact, trees are very important for all living things on Earth. To begin with, forests are a safe place for animals, insects and plants to live. Trees are also good for us humans because they take in greenhouse gases like CO2 and produce oxygen. This means they help create a clean environment for everyone on this planet. Trees make our lives more convenient. Many of the things around us, such as paper and pencils, come from trees. Just look around your room—a lot of the furniture is made of wood. Trees also provide us with delicious fruit and wonderful drinks. For example, we can make tea from the leaves of the tea tree. Trees do so much for us. We can’t imagine a world without them. However, humans are not treating trees in a kind way. We are cutting down forests all around the world. We are polluting the water and the air, and this harms trees. All these things are a big problem. We need to do more to protect trees and save our planet.
