If there is no water component,

Water is something that nothing in the world can do without. It looks unremarkable. In fact, if there is no water, how serious it would be! Therefore, throughout the ages, people always regard "saving water is everyone's responsibility." This sentence is on the tip of my tongue. However, have you ever thought that you can't just talk without practice, but you should take practical actions. Because without water, what will we face?

The main sources of water are: natural rainfall, glacial meltwater, groundwater, hot springs and snowmelt.

When washing clothes, vegetables, etc. The water is getting dirty, just like countless tiny "bad smokers" soaking in the water, gradually dispersing and becoming dirty stains. If there is really no water in nature, how can human clothes and vegetables be cleaned? The food we usually eat must also be washed with clean water, but if there is no water in the world, our food will not be washed. In the long run, people's health will be destroyed, and worms will grow in their stomachs, causing abdominal pain and dysplasia. Think about it, do you want to see such consequences? The crops we eat are irrigated by water. If there were no water, where would thousands of crops in Qian Qian come from?

We usually see many lively and lovely goldfish in the pond of the park, so how can this beautiful and lovely little animal survive without water? Do you have the heart to make this animal disappear?

If a person doesn't drink water, there is not enough water in his body, and his body is unhealthy, as is everything in the world.

If there is no water, even chocolate and ice cream that everyone loves can only wander in our hearts, but they have disappeared!

Let's wake up and stop wasting water. Water will disappear if we don't cherish it. Without water, plants will die, animals will die of thirst, and nature will be covered with dust everywhere. How barren and terrible our world will become!

Please act: "it is everyone's responsibility to save water!" " "

"The last drop of water in the world is our tears", please don't let such black humor become a reality!

In the starry universe, there is a blue star that gave birth to life. She is the earth. For more than 5 billion years, the earth has been changing every day. About 2 million years ago, when human beings were born on the earth, this lovely planet prepared a beautiful and comfortable living environment for human beings-vast land, vast ocean, dense forests, green mountains, green grasslands, fresh air, clear rivers, charming lakes-charming nature! The eagle strikes the sky, the fish is shallow, the trees are majestic and the flowers are beautiful ... These energetic life activities are vivid poems, exciting songs and the beauty of nature!

On our lovely earth, there are choppy oceans, endless rivers, calm and charming lakes, snow-capped mountains wrapped in silver, dazzling glaciers, underground undercurrents, spewing springs, silent rain and flying snow. These are all water.

You must have seen such a public service advertisement. There is a faucet on the TV screen, which is dripping with difficulty. The dripping speed became slower and slower, and finally the water was used up. Then a pair of eyes appeared on the screen, and a tear flowed out of them. Followed by this sentence: "If human beings don't cherish water, then the last drop of water we can see will be our own tears."

Water is the source of life. If there is no water on the earth, then the earth will not give birth to our descendants from generation to generation. Because the earliest primitive life was first bred in the ocean and gradually extended to the land. Therefore, water is the cradle of life. The survival and development of human beings are also inseparable from water. Because we have to drink water every day, food growth can not be separated from water, and industrial production can not be separated from water. Water is also the "air conditioner" of nature. In the hot summer, when people feel unbearable heat, if only it could rain! Walking by the sea, the sea breeze blows gently, sweeping away the hot and irritable mood; When the cold winter comes, the seawater continuously transfers the stored heat to the surrounding land ... all these are the functions of water.

The first life was born in water. Hundreds of millions of years ago, under extremely accidental circumstances, some substances happened to combine together in a specific form in water, so the first single-celled life on earth was born. It may be the ancestor of all life on earth today.

My hometown Xuancheng is located on the bank of the Yangtze River, and Yangjiang passes through here. This is a veritable "land of plenty". The unique geographical conditions make people here have an intuitive and profound understanding of water. But we can't understand the urgency of water shortage, and the waste of water resources is more serious. In order to correct this bad habit, we should keep in mind "water-the blood of the earth".

On the surface, the water reserves on the earth look great. (m.taiks.com) The area covered by water is 380 million square kilometers, accounting for 70% of the earth's area. It is estimated that there are about 654.38+0.39 billion cubic meters. Some people even suggested calling the earth "water polo". But about 97.3% of the seawater can't be directly used by human beings, 2. 14% comes from glaciers and polar ice sheets, and 0.6 1% comes from deep groundwater. However, the amount of freshwater resources (rivers, freshwater lakes, reservoirs and shallow groundwater) that can be restored and updated to maintain the life activities of human beings and animals and plants on land is very limited, which is estimated to be only about 1.2 trillion cubic meters, less than one tenth of the total water storage capacity of the earth. This part of fresh water is the source of life for human beings and terrestrial creatures. Although dynamic balance can be maintained for a long time, its quantity is extremely limited in a certain time and space, and it is not inexhaustible as some people thought before. With the disappearance of water resources, human beings will perish, and so will the earth.

I cringe at the thought, just like Pandora's box opens at the touch, and the disaster is out of control. In the end, the world will be dark, and ugliness will become another generation of nouns. I can't help wondering who opened the box of this disaster. -Humans, pathetic humans! Seize the tail of time, cherish water resources and protect the water of life!
