There are many beautiful, cool, fashionable and expensive cars and sports cars on the market now, and many wealthy people, big and small, want to spend money to buy "face". But is this really the so-called "face"? This is vanity, waste and luxury. For a car, buy one that is environmentally friendly, elegant, dignified and practical, and that reduces carbon dioxide emissions. Environmentally friendly gasoline and diesel can improve vehicle performance. It can clean the car's engine, reduce engine friction, and enable fuel to be burned more fully, thereby reducing air pollution. In addition, I want to tell those rich people: People will not respect and admire you just because you have money and lots of money.

I remember that when I was 10 years old, my sister and I loved playing with water, and we could be called "water masters." One day, while our aunt was not at home, we started playing in the water vigorously. We first filled each basin with water to make a 'back bomb', picked up the bottles and splashed each other hard. When we were tired, we all took a rest. Unexpectedly, since my sister started playing sneak attack, I also fought back. Finally we All the clothes were soaked. I had an idea and thought of another way.

I know that the water meter will stop running if I turn the water on low. I told my sister to turn the water on low. My sister didn’t believe it and asked in surprise: “Can you really stop the water meter running?” “No. If you believe it, try it for yourself!” Sure enough, it’s exactly what I said. I mysteriously said to my sister: "Yesterday, I didn't turn off the faucet after washing my face, and the water meter didn't run either.

"My sister said happily: "Then let's collect water quickly! But I frowned and said, "But it's too slow!" "It doesn't matter, just take your time!" "After our parents came back, we scrambled to tell our parents a "secret", thinking that they would praise us. Who knew, my father said to us in a serious voice: "What are you doing?" This is stealing water. Who asked you to do this? This is a waste of water. "After listening to my father's thoughtful words, my sister and I's faces suddenly turned red.

Water is an indispensable part of human beings. We don't let the last drop of water become our tears. .

Water is an important raw material for industrial and agricultural production, and it is also a precious natural resource that human beings rely on for survival. Without water, there would be no life, no good natural environment, and sustainable social and economic development cannot be achieved. . Today's world has entered an era of water shortages, and a global water crisis has emerged. Compared with other countries in the world, the situation of my country's water resources and water environment is even more worrying: First, my country's total water resources were in serious shortage. my country's per capita water volume is 2,251 cubic meters, which is only 1/4 of the world's per capita level. It is predicted that when my country's population increases to 1.6 billion in 20xx, the per capita water resource volume will drop to 1,760 cubic meters. Second, the spatial and temporal distribution of my country's water resources will also change. It is very unbalanced. The absolute amount of water resources is less in the west and more in the east, while the per capita amount is scarce in the east and abundant in the west. Third, my country's water environment is also deteriorating, resulting in a decrease in water resource availability. With economic development, population growth and urbanization, my country's demand for water resources will further increase in the future. How to solve the problem of insufficient water supply and increasing demand has become a major issue that needs to be studied and solved. .

In today’s world, fresh water only accounts for 3% of the total water, and two-thirds of it is ice. This shows how poor the world’s water resources are now. “If there is only the last one left on the earth! A drop of water is our tears. "Every time I hear this sentence, I can't help but feel nervous, afraid that this will happen one day. Now, China is really developed: there are many factories and high-rise buildings everywhere. The population is increasing, and the water supply is not enough. Yes, saving is enough, but people waste it wantonly, and with pollution, China has become one of the twelve water-poor countries in the world.

We must save! Use water, don't let the last drop of water become our tears!
