简洁一些好.
It is well known that the global enviroment is destroied seriously with developing of the industry and the human civilization. For example, most instance of water pollution, air pollution, illegal forest cut and population density increasing are assenting local in nature. Nowadays the earth is getting warmer and warmer with rising levels of carbor dioxide. In other words, is has taken place in every country that the amount of chlorine is increasing in the atmosphere, it can allow through the atmosphere to the global surface. If its levels continue to increase all animal and plant life will face a new threat to their life or survive. In fact, it threaten straight the human being. For a simple example, now ,it is apparent that the varieties of disease are appearing and threaten the human health.
To sum up, all the threat are known by many people, but others people are still to destroy the enviroment, some factories are sidcharging the poisinous liquids or gases into the river or atmosphere of cause, human civilization become the dominant cause of charge in the global enviroment. Therefore, we must protect our ecological system!

Nowadays the earth is getting warmer and warmer with rising levels of carbon dioxide. In other words, is has taken place in every country that the amount of chlorine (is it chlorine?) is increasing in the atmosphere, it can filter through the atmosphere to the global surface. If its levels continues to increase, all animal and plant life will face a new threat to their survival. In fact, it directly threatens human beings. For a simple example, now, it is apparent that the varieties of diseases are appearing and threatening human health.
To sum up, all the threats are known by many people. But other people are still destroying the enviroment. Some factories are discharging poisonous liquids or gases into the rivers or atmosphere on purpose. Human civilization has become the dominant cause of charges into the global enviroment. Therefore, we must protect our ecological system!
