Forests are very important to the enviroment because they use carbon dioxide (CO2) and produce oxygen. They also provide shelter and food for many different types of plants and animals.Trees are cut down for many reasons but the main reasons are to make space to build new houses and to clear land to grow grass for cows and sheep to eat, to produce dairy foods. The trees which are cut down are sold and they are made into paper and furniture.Cutting down trees is called deforestation and it can have serious effects. If animals’ homes, which are built in and around the trees, are destroyed, many species will become extinct.Deforestation also affects the climate. When rain falls on a forest, new clouds are created. If huge areas of trees are cut down, clouds do not form, rain does not fall and the land becomes drier. The CO2 builds up and adds to the global warming which is making the Earth become hotter.
