Water is the foundation of all life and indispensable for social and economic development. Some people think that water is inexhaustible. In fact, their ideas are completely wrong. Let me talk about water!
Water plays an important role in forming human tissues and supplementing nutrition. There are many rich minerals in drinking water, which are beneficial to human health. At the same time, water can also help the body digest food, absorb nutrients, eliminate waste, and play a lubricating role between organs.
Many people imagine the earth as a blue planet, in which 7 1% of its surface area is covered by water. In fact, 97.5% of the water on the earth is salt water and only 2.5% is fresh water. In fresh water, nearly 70% is frozen in the ice sheet, and the rest is soil water or deep groundwater, which is difficult for human beings to use. Water from rivers, lakes, reservoirs and other sources can be easily used by us directly, but its quantity is less than 1% of the world's fresh water.
, accounting for about 0.007% of all water on the earth.
Some people just don't know how to cherish water. When they brush their teeth, they leave the tap on all the time. After taking a shower, the water is still on. A big bowl of water is enough to flush the toilet, but a big bucket is needed. When washing the car, I washed it over and over again, as if I couldn't wait to brush the body with a thin layer of "skin" before giving up. After washing, I threw Shui Pi's pipe to the ground with a bang. When the water was cut off, the tap was not turned off, and the water came and flowed, and no one came to turn it off. The phenomenon of wasting water exists all over the world.
If there is no water in the world, the land will be dry. Without water in the river, all the fish and shrimp will die of thirst, and all the crops will die of drought. We can no longer appreciate the great rivers and mountains of the motherland. A tree will wither, patches of grass will wither and flowers will wither. In the past, the forest was vast, leaving only jagged rocks. The hoarse cry for help of birds will make people cry, and the desperate cry of dogs will make people feel like a knife. All living things can't escape the terrible palm of death.
To save water, I have a trick: at home, rice washing water can be used to water flowers, and face washing water can be used to wash feet and water flowers. When washing a car, wiping with a rag is more effective than washing with water. When washing the toilet, you can use rainy water. At school, you can drink as much water as you want, and don't leave a drop. When physical education class comes back, if it is very hot, you can turn down the tap and wash your face with your little hands. When washing mops and rags, first pick up half a basin of water. Don't drain while washing, it will waste a lot of water.
Finally, I want to say, "If we don't save water, the last drop of water in the world will be your own tears. So we should not waste water in the future, but cherish, protect and save water. Only in this way will our earth become more and more beautiful. Let's act together! "
