Great arguments, Mohamed. I agree with you that the rainforest's shouldn't be cut down because it contains a lot of oxygen, as you said it's the "lungs of the earth".

I think the rainforest should be saved because it provides us with things we need to live. The rainforest's provide us with clothes, food, medicine, oxygen and many more. If many rainforest's were to be cut down today then we wouldn't have medicine for a lot of disease. Scientist are also looking for the cure to Cancer, Aids, Diabetes, Arthritis, and many more. If the rainforest were cut down we might never find the cure to these diseases.

The rainforest also provide us with many clothing that comes from plants. Cotton comes from a certain plant, if that plant never existed then we wouldn't have cotton clothing. The rainforest also provide us with oxygen. If the rainforest were cut down it would be very hard for us to survive with oxygen that doesn't come from the rainforest. If the rainforest were cut down we would be killing 50% of all plants and animals in this world.
