As we know, the nature is the most important to human. People depend on the nature to live and human need fresh air, water, vegetable, which al come form the nature. The industry need fuel, raw material, which also root form the nature. What’s more, human also belong to the nature, he is high animal existing in nature. As a consequence, if we destroy the nature, in some extent, we will diminish ourselves.
However, human beings haven’t paid more attention to this argument. They upset the ecological balance and destroy the environment surrounding. For example, smoke stacker have disgorged poisonous gases into the atmosphere; factories have dumped waste into rivers and streams; forests have been felled out; citizens haven dumped rubbish everywhere; groundwater have been drawn out unrestrictedly. As the scientists predict, it become dangerous to us if we continue to do so. And in some day, human being will destroy the whole earth and can’t to live any longer.
