The future of the earth a deep night, I go into the sweet dream, I dream of the future of the earth. I dream of the summer of 2199, ultraviolet light passes through the thousand million holes in the ozone layer, shoot to earth, if people want to go out, get a special umbrella or wear special clothes. The earth's plants and animals have been extinct for tens of thousands of species, the rest are near death. In the hospital, the patient does not stop him, than simply have the Spring Festival also busy. The cars on the highway are whining to spray the smell, the original air pollution add a pollution. Oil companies to drill, the earth drilling a hole, the Earth billions of years of savings to dig out. And - - - - - - I was dream wake up, I can not help thinking: why do humans broken earth? Why? I see light suddenly: does the human have not seen a systemic disease, ugly earth crying? The earth is too lovely, also too easily broken, human is the best doctor, we should save earth, save ourselves.
