ng time ago, we never noticed that we are in a situation that the water on the earth is less than before, and the consequence is continuing.
Until recently, we have started to acknowledge that we should make the bigger efforts to save water. Therefore, so save water from every single person is important. That is why we should save water at home. If every one of us saves water at home, then the water saved together would be a huge amout. And I have some suggestions following: we could cycle the water we just used them to wash clothes to water the plants or to rush the toilet; when we wash our hands, we could turn the tap off for the moment we put soap on our hands etc.
So if we want to save water sincerely, we could save it at home .
Some people think there's much water on the earth.In fact,there is only a little water for us to use now.If we don't save it,it will surely be used out some day.
Then what should we do?
First,when we finish washing the clothes,we can use the water to clean the floor.Second,if we see the dripping tap,we ought to fix the tap as soon as possible.Third,we can have a shower instead of a bath because having a bath can waste a lot of water.
In these ways,we can save not only huge amounts of water but also ourselves!
Water is very important in our life. We drink it every day and use it to cook and wash things. We can not live without water. But how can we save water? There are several ways to save water. Firstly, take shorter showers and don’t leave the tap running when we don’t need to use water. Secondly, Try to reuse water . It’s the most important way for us to save water. At last, We should not pollute water so that we willl have fresh water for years and years. If we do not save water, the last drop of water will be a teardrop. To protect water is to protect our life.
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 .
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.
Saving water means saving ourselves
Water is the basic source of life. There would be no life without water.
More and more water is needed in the modern society.
Many places are short of water; many rivers and lakes are polluted. What’s worse, many people are wasting water.
In order to protect water, let’s do something to fight against all kinds of pollution and waste of water.
