Protect the earth
There are three pictures: the first one is a car that producing the polluted air; the second one is a place that is sinking into the sea, maybe the earthquake happened just now; the last picture is a thunder over the sea. Just as the picture shows, environmental problems are becoming more and more serious all over the world. So there is no time for us to delay in protecting the earth.
First of all, we need to know how we destroyed our environment. With the development of industry and agriculture, more and more natural resources were exploited. And many more cars and factories appeared. But, cars make the air unhealthy for people to breathe and poisonous gas is given off by factories in the meantime. Trees on the hills have been cut down and waste water is being poured continuously into the rivers. Furthermore, wherever we go today, we can find rubbish carelessly disposed. Pollution is, in fact, threatening our existence.
In the second place, we have to know what we can do to protect our environment. Here are some ways. First, we can stop driving our personal cars. We can go to work or school on foot or by bus. Not only can it protect our environment, but also it is good for our health. Second, we are not supposed to drop litter anywhere, we should put them into the trash bin. And it is the best to pick up the litter on the ground when we see them. Third we should save the paper, the water, the food and so on. Fourth, we should protect the trees and we should plant more. Last but not least, it is necessary for us to resist the disposable chopsticks and plastic lunch box.
The earth is our home and we have the duty to take care of it for ourselves and for our later generations. Fortunately, more and more people have realized these problems. Measures have been taken to cope with these problems by the government. Laws have been passed to stop pollution. I hope the problem will be solved in the near future and our home will become better and better.
