【世界水日英語作文一】

The world is not only hungry,but also thirsty for water. This may seem strange to you, since nearly 75 % of the earth's surface is covered with water. But about 97% of this huge amount is sea water, or salt water. Man can only drink and use the other 3% -- the fresh water that comes from rivers, lakes,underground, and other sources. And we cannot even use all of that, because some of it is in the form of icebergs and glaciers. Even worse, some of it has been polluted.

However, as things stand today, this small amount of fresh water, which is constantly being replaced by rainfall, is still enough for us. But our need for water is increasing rapidly-- almost day by day. Only if we take steps to deal with this problem now can we avoid a severe worldwide water shortage later on. A limited water supply would have a bad effect on agriculture and industry. Let me give you just one small exampie of how necessary water is to industry. Did you know that to produce a single ton of steel, it takes about 91, 000 liters of water?

We all have to learn how to stop wasting our precious water. One of the first steps we should take is to develop ways of reusing it. Experiments have already been done in this field, but only on a small scale. For us, the systems are as important as the spacecraft.

it is generally believed that there is a good supply of fresh water. but to our disappointment, the fact is just the opposite.

as we can see, the world population is growing rapidly day by day. so enough fresh water is needed to feed such a big population. what's more, with the development of industry, factories and vehicles produce poisonous gases or wastes, which consequently results in the pollution of water. though fresh, a good amount of it can no longer be used.

only quite limited fresh water resource is available to human beings. so it's high time for us human beings to take quick action to protect water resource. stop pollution and save water, otherwise, we cannot survive on the earth.
