题目解答
答案
Environmental problems are becoming more and more serious all over the world. Pollution is, in fact, threatening our existence.
For example, cars and factories are always giving off gases, which makes the air harmful for people to breathe in. Waste water is being poured continuously into rivers without being treated, damaging the source of our drinking water. Furthermore, wherever we go today, we can find rubbish everywhere, polluting air, water and the earth.
I firmly believe it is time for us to take effective measures to protect the environment. On one hand, the government can pass laws to make sure polluted air and waste water are carefully cleaned. On the other hand, we should stop wasting water and throwing garbage everywhere. Maybe, the most important is to develop an environmentally friendly lifestyle to reduce the growing waste pollution.
Only by our joint efforts can we make a difference to the environmental protection and leave a green earth to our future generations.
