We face many polluted problems as the technology develops,and among all the pollutions, I think air pollution triggers the most problems. Firstly,owing to car's exhausting gas, the acid rain is getting worse and worse. Secondly, certain part of materials of the air conditioners bring about holes in ozonosphere. Furthermore, that makes our environment become a greenhouse effect. Lastly, more and more diseases appear because we no longer have fresh air. Therefore, when we benefit from the convenient technology, we should also find a good way to protect our own environment.
