It is undeniable that the worsening environment has become the biggest concern of the present-day world. Land resources are dwindling because of water loss and soil erosion.

Waste gases poison the air we breathe. The rivers and lakes are polluted by waste dumped in them from factories. It is probably no exaggeration to say that deterioration of the quality of the environment threatens the existence of mankind itself.

Some people are of the opinion that the environmental problem is the price we have to pay for economic development.

But I do not think that this argument is valid. After all, what is the point of economic growth if people's lives are adversely alfected by worsening environmental pollution ?

结尾：总之，保护环境是一项非常重要的任务，我们每个人都应该积极参与，尽力减少对环境的污染和破坏。让我们共同努力，为了我们的子孙后代和地球的未来，共同打造一个美丽、清洁、和谐的世界。

保护环境，人人有责责，地球是我们唯一的家园，我们要像爱护妈妈一样去爱护它
