In distant past, when ozone layers did not exist on the earth, large amount of ultraviolet rays reached the surface of the earth directly and no creatures could live there. However, the emergence of ozone layers reduced the amount of ultraviolet rays, leading to the earth of today, where many kinds of creatures live. Now, the ozone layers, which protect the earth from ultraviolet rays, are being destroyed by humans and are going back to what it used to be before living things emerged. If ozone layers were to be completely depleted, ultraviolet rays would reach our skin directly, which would cause cataract or skin cancer. The earth would become an inappropriate place for creatures to live in. We always have to be thoughtful about our environment. Of course we should not only avoid emitting CFCs but also consider other environmental problems. Today the earth is suffering from many kinds of environmental problems. Why don't you start with small things around you to protect our planet Earth?
