Pollution of environment

?These days we often hear that (our living conditions are getting more and more serious because of the destruction of our environment ).It is common that (many trees and animals are near extinction, and the all-important food chain has been destroyed.).

??Why does such circumstance occur in spite of social protects? For one thing, (the population of the world is increasing so rapidly that the world has been so crowded. ).For another,(the overuse of natural resources has influenced the balance of natural ecology ). What is more, since (the industrial revolution ),it is natural that (a great number of factories have been springing up like mushrooms. The smoke and harmful chemicals released from factories also pollute the environment). ??To solve the problem is not easy at all, but is worthing. We should do something such as (planting more trees, equipping cars with pollution-control devices and learning to recycling natural resources )to improve the present situation, and I do believe everything will be better in the future.

对环境的污染

?这些天，我们经常听到的是很常见的，（我们的生活条件越来越严重，因为我们的环境破坏）。（许多树木和动物都濒临灭绝，和所有重要的食物链已经被破坏。 ）。

??为什么会出现这样的情况下虽然社会功能保护？对于一件事，（世界人口的增加如此之快，世界已经如此拥挤。），另一个原因是，（对自然资源的过度使用已经影响了自然生态的平衡）。更重要的是，因为（工业革命），这是很自然的（大量工厂已如雨后春笋像蘑菇。工厂释放的烟雾和有害化学物质，也对环境造成污染）。 ??要解决的问题是不容易的，但沃辛。 （如种植更多的树木与污染控制设备，汽车装备和学习回收利用自然资源），以改善目前的情况，我们应该做的事情，我相信在未来，一切都会好起来。
