Trees are cut for lumberDuring last years, trees are cut because we want to build or construct.We don’t care about trees because we want our homes, our furniture and our business. But anyone of as asked the animals, the forests if they want that?

Our activities harm the environment because without trees we don’t have oxygen and without oxygen we can’t breath.Slide4

Forest arsons are very bad because they destroy environment and the oxygen is reduced.Slide5
