توضیحات
Miles overhead, a thin layer of ozone gas blankets the earth, shielding life on the surface from the sun's deadly ultraviolet radiation. But this protective cover is shrinking, destroyed by chemicals released into the atmosphere. As a result, more UV rays now reach the ground, and skin cancer is on the rise.
