水被污染会给人类带来灾难作文100字
环境污染会给生态系统造成直接的破坏和影响，如沙漠化、森林破坏、也会给生态系统和人类社会造成间接的危害，有时这种间接的环境效应的危害比当时造成的直接危害更大，也更难消除。
例如，温室效应、酸雨、和臭氧层破坏就是由大气污染衍生出的环境效应。
这 种由环境污染衍生的环境效应具有滞后性，往往在污染发生的当时不易被察觉或预料到，然而一旦发生就表示环境污染已经发展到相当严重的地步。
当然，环境污染的最直接、最容易被人所感受的后果是使人类环境的质量下降，影响人类的生活质量、身体健康和生产活动。
例如城市的空气污染造成空气污浊，人们的发病率上升等等；水污染使水环境质量恶化，饮用水源的质量普遍下降，威胁人的身体健康等。
严重的污染事件不仅带来健康问题，也造成社会问题。
随着污染的加剧和人们环境意识的提高，由于污染引起的人群纠纷和冲突逐年增加。
让我们都来关爱自然，热爱地球吧，手挽手、肩并肩、心连心地铸起一道绿色环保的大堤，捍卫资源、捍卫环境、捍卫地球、捍卫我们美好的家园吧

急需一篇写水污染的英语作文 100字
Water pollution 水源污染 个 以随意选择喜欢的文字~ Water is used in homes, in farming, and in manufacturing. The water used by the people comes from oceans, lakes, rivers, and streams. Many water sources are becoming polluted. People are throwing things into the water. Factories are dumping waste materials into the water. Cities are dumping sewage into the water. Some water sources have become so badly polluted that the water cannot be made fit to use. Would you like to drink water that came from a source that had been so badly mistreated? Now is the time that we should take up our responsibility to protect our environment from being polluted. -------------------------------------------------------------------------------- Water pollution is caused by waste from factories and cities. Oceans are able to clean themselves, but certain seas, once they become dirty, are not able to do so. One example is the Mediterranean which lies between Europe and Africa. It has onlyeone narrow entrance to the ocean in the west. On quarter of the shores of the Mediterranean are polluted and are no longer safe for swimming, as a lot of diseases are present in the water. In most places it is not safe to eat the fish. Lakes also have the same problems. Lake Baikal in Asia was once the cleanest in the world, with over 700 different kinds of plant and animal life. Now, however, the waters of this great lake, which is also the world\\\\'s deepest (over 1,740 metres), have been dirtied by waste from a chemical factory. In 1989 an oil tanker hit a rock off the northwest coast of Alaska. 35,000 tons of oil poured into the sea. The accident was one of the worst in history. More than 34,000 birds and 10,000 animals were killed. 4,800 square kilometres of ocean were polluted. -------------------------------------------------------------------------------- Spring is the best season of the year. The weather gets warmer and warmer. My clas i\\\\'amates and I took a one-day sightseeing around our city.The scene was pretty. But when we saw the rivers along our city, I felt very sorry, and thoughit a lot. With the development of modern agriculture and industry, more and more waste water is being poured into rivers. It has caused serious pollution. The river is becoming so dirty that no living things can live in it. The river is giving off a terrible smell. We make an urgent appeal that measures should be taken to cope with the situation. Our government should start building various facilities such as sewage treatmentplant and encourage scientists to work out more and better ways to reduce the pollution of water. Water is tho source of our lives. It is very important to protect water. -------------------------------------------------------------------------------- My classmates and I had an outing this spring. We had a good time. But meanwhile I noticed that water pollution in our city was becoming more and more serious. On our way, we could see women washing clothes in the river. Litter was floating on the river. Waste water produced by a chemical factory was being discharged into the river. We did not see any fish in the river. The fiver was not so clear as before. Water quality was very bad. I am worried about it because water is important to all living things. Man can not live without water. I hope people pay more attention to this problem, especially the government. Try to control the pollution of water as early as possible. At last I would like to say, To protect water is to protect life.
保护水污染的感想100字
小作文啊，首先看图片，主要看污染的程度，然后可以根据自己的想象（不能太离谱），接着写出未来会是什么情况，主要是这样。
要自己概括
关于水的作文100字，描写性的
水，是生命的源泉，是滋润着世间万物的重要“人物”。
可是，我们呢
一再的浪费它，污染它…… 现在想想，在缺水的地区：她们做饭、喝水不都要用水吗
有时她们连喝一口水都难。
而我们这边的生活好的却开始浪费水了，工厂排的污水、垃圾……纷纷流入了小河、大海…… 我想，如果我们保护环境，更加珍惜水资源，那么，小河的应该谁是清澈见底的吧
大海应该是碧绿色的吧
每当你在浪费水时，就想想贫困山区的人们吧，告诫自己：别浪费水了。
不然，最后一滴水将是人们的悔恨泪。
