he 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.
Many people believe that the world’s supply of fresh water will never be used up. They think that fresh water comes from such a variety of sources that it is always sufficient for use. Such an opinion leads to a shocking waste of water.
As a matter of fact, the earth is short of fresh water. Furthermore, with the rapid growth of the world population, the rising demand for water by industry, and the serious pollution of our surroundings, the world is facing the ganger of running out of fresh water. Actually, in some big cities, fresh water can not meet the daily needs.
Therefore, to find new ways to save water is an urgent task. First, we should pass strict laws to control any waste of water. Second, scientists must work even harder to purify sea water, and try to find substitute to reduce the use of fresh water.
Maybe the last water is our tears
As we know water is made up of our life,we could not leave without water.No water will no we.
Water is needed more and more,because our industry and agriculture produce developed fast.Somewhere water are scare,and some rivers are no water in them.But just little water is polluted,more waste water did not handled and discharge into river.
Around us there are a lot of students don't pay attention to save water,for example: after they washing their face and rinsing the mouth,they don't turn off the water tap .Let the water flowing day and night. What a pity!
Expect the tings I just mention,there are more and more in our life.So now I hope our students take care of wate.And the same time we need do things to prevent water pollute as we can do .That's what I want to say.Why not do it right now,come on .
