How to save water 1 Water is very important in our life. As human beings, we are an organization based on water and oxygen, just like many organizations on earth. Without water, we will die of dehydration.
The crust accounts for less than 1% of the earth, and all the oceans on the earth are in the crust. Therefore, water accounts for less than 1% of the earth. "A drop of water is a drop of life." The human body is about 70% water. We depend heavily on water for survival.

How to save water We are now paying more attention to many environmental problems we have created before, one of which is the shortage of water resources. A long time ago, we never noticed that we were in a situation where there was less water on the earth than before, and the consequences were continuing.
Only recently did we begin to realize that we should try our best to save water. Therefore, saving water is very important for everyone. This is why we should save water at home. If each of us saves water at home, the water saved together will be a huge amount. I have some suggestions as follows: we can recycle the water we just used to wash clothes, water flowers or flush toilets; When we wash our hands, we can turn off the tap when we put soap on our hands.
So if we really want to save water, we can save water at home.
The world is not only hungry, but also saves water. This may be a little strange to you, because nearly 75% of the earth's surface is covered with water. But about 97% of this huge amount is seawater, or salt water. Humans can only drink and use another 3% of water, that is, fresh water from rivers, lakes, underground and other sources. We can't even use them all, because some of them exist in the form of icebergs and glaciers. To make matters worse, some of them have been polluted.
However, as far as today's situation is concerned, this small amount of fresh water is constantly replaced by rainfall, which is still enough for us to use. But our demand for water is growing rapidly-almost every day. Only if we take measures to solve this problem now can we avoid serious water shortage in the world in the future. Limited water supply will have adverse effects on agriculture and industry. Let me give a small example to illustrate how important water is to industry. Do you know that it takes 9 1 1,000 liters of water to produce one ton of steel?
We must all learn how to stop wasting precious water resources. The first step we should take is to develop ways to reuse it. Experiments have been done in this field, but only on a small scale. For us, these systems are as important as spaceships.
If the world is not only hungry but also short of water. This may be strange because nearly 75% of the earth's surface is covered with water. But about 97% of this amount is seawater, or salt water. People can only drink it and use another 3% water-water from rivers, lakes, underground and other sources. We won't use it, because some or even all of them are in the process of iceberg and glacier formation. To make matters worse, some of them have been polluted.
However, due to today's situation, this small amount of fresh water, some of which are constantly replaced by rainfall, can be adjusted to be enough for us to use. However, in Aarmo, our demand for water is increasing day by day. Only when we take measures to solve this problem now can we avoid serious water shortage in the world in the future. Limited water supply will adversely affect agriculture and industry. Let me show you how small this industry is. Do you know that it takes about 9 10000 liters of water to produce a ton of steel plate?
We must all learn how to stop wasting precious water resources. As a first step, we should adopt the method of development and reuse. Experiments in this field have been completed, but only on a small scale. For us, it's just that the system is an important spacecraft.
