waste water is being poured wherever we go today,Who is willing to drink the polluted water? It can cause us to be ill and even to die. We can't wait for a moment to protect our water sources. The water we use comes from oceans, lakes, rivers or streams. But many of these water sources are getting seriously polluted. Towns and cities are pouring dust into the water. Many people are throwing all kinds of dirty things into the water. Factories are pouring waste material into the water. Therefore, water sources have become so badly polluted that some of the water is unfit to drink or to use. Now it is high time that we should do something to protect our water environment from being polluted.
we can find rubbish carelessly disposed. Pollution is, in fact, threatening our existence.rubbish may cause a lot of pollution. It may pollute the air, the water and the places we live in. For another, it may do harm to people's health.
So in our city, rubbish is well dealt with. First, it is sorted. Then old newspapers and glass are recycled. The harmful wastes are buried and the waste water is cleaned before it goes into the river. The government has already made laws against pollution caused by rubbish.
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.
污水不断被排入河里,污染的水会使人生病甚至死亡,有谁愿意喝这样的水呢?我们要保护水源,刻不容缓。我们用的水来自海洋、湖泊、河流或小溪,但这些水源有许多正受到严重的污染。城镇把大量的尘埃排入水中,许多人正把各种各样的脏物投进水中,工厂正把废物排入水中。因此,水源已经污染严重,其中一些不适合再饮用。现在到了.采取措施保护水环境使其免受污染的时候了。
另外,无论我们走到哪里,到处可见随意丢弃的垃圾。事实上,污染正威胁我们的生存。垃圾会导致污染。它会污染空气、水和人们居住的场所。其次,它会危害人类健康。
所以我们在城市中,垃圾得到了妥善处理。我们首先将垃圾分类,然后可将旧报纸和玻璃制品进行再生利用。有害的废物要被掩埋,污水要在净化后才排入河流。政府已经制定了规章,禁止垃圾污染。
地球是我们的家园,我们有责任为我们自己和我们的后代去照顾好它。庆幸的是,愈来愈多的人们已经意识到这些问题。政府已经采取了很多措施去解决这些问题,法律已被通过以制止污染。我希望这些问题在不远的将来能得到解决,我们的家园变得越来越好。
