Who is destroying our earth?

We are slowly destroying our earth. Firstly, we are cutting down more and more trees for many reasons. We need trees to build houses, to clear land for different uses or to cook food. If we cut down more trees, there will be more floods. Secondly, we are producing too much dirty smoke. Smoke comes from motor vehicles and factories in many parts of the world. It pollutes the air and affects our health. Wastes from factories around the world harm also our land and water. We might not be able to grow enough food to eat in the future. We might not have enough fresh water to use. Our earth is in danger. If we don’t work together to save the earth now, it will be too late.
