If you don t cherish water resources, the last drop of water in the world is your tears

Trample on my head today, plant your grave tomorrow!

Water, especially freshwater, is the root of the earth's spirits!

The grass is green, and the feet are merciful. Please, please choose me.

Don't let our tears become the last drop of water in the world, this is to tell us that we should take care of water resources, because if you don't cherish it now, the last water resources will be gone, and in the end we can only cry ourselves. Here's an extended look at tears.

tears (yǎn lèi) is a liquid, a liquid that flows from the eyes of a person when they are sad or overly excited and happy, with a slightly salty taste. Normally, a small amount of clear, salt-containing solution secreted by the lacrimal glands diffuses between the eyeball and eyelids, making it moist and easy to move, and usually enters the nasal cavity through the nasolacrimal duct. It is a weakly acidic, transparent, colorless liquid, most of which is composed of water (, and contains a small amount of inorganic salts, proteins, lysozyme, immunoglobulin A, complement system and other substances.

Causes. Tears do not exactly indicate a change in mood. When a foreign object such as dust falls into our eyes, a large number of tears are generated and the foreign body is washed out. In addition to a large amount of water, there are lysozyme, immunoglobulins, complement system, lactoferrin, -lysin, etc., which have the effect of inhibiting the growth of bacteria.

Therefore, tears have another very important function - defense.

Charles Darwin, the founder of the theory of evolution, once speculated that tears were some kind of evolutionary "relic" and had nothing to do with the competition for survival in the evolutionary process. When you cry, the microvessels around the eyes become congested, and the small muscles contract to protect the eyes, causing the lacrimal glands to secrete tears.

Darwin believed that for the human body. Tears themselves are meaningless "by-products".

The American anthropologist Ashley Montago had the opposite view of Darwin. He believed that tears had benefits for the human body, and that this benefit had an impact on evolution. Thus being preserved from generation to generation through natural selection, human tears are the result of the survival of the fittest.

For example, he said: Tears contain lysozyme, a self-defense substance that protects the nasopharyngeal mucosa from bacterial infection. Dry crying without tears has been observed to dry out the nasopharyngeal mucosa and become infected.

A growing number of scholars agree with Montago that tearing may have some benefits for the human body.

The last drop of human water is its own tears.

To cherish water resources, people often destroy the environment nowadays, and if this continues, the only water left for human beings will be their own tears. Therefore, through this advertisement, we must not destroy the ecology and destroy water resources.

Calling on people to save water fully illustrates the importance of water to human beings.

This sentence means: cherish water resources and save water.

As the saying goes, "A person can go seven days without eating, but he must not go without drinking water for seven days" Yes, water is one of the indispensable conditions for human survival, and without water, there will be no life.

Seventy per cent of the Earth's surface is covered by water, but freshwater resources account for only one of all water resources, nearly 70 per cent of which is fixed in the ice of Antarctica and Greenland, and the rest is mostly soil moisture or deep groundwater, which cannot be used by humans. Less than 1% of the earth's freshwater or about water can be directly used by human beings, and the per capita freshwater resources of Chinese account for only a quarter of the world's per capita freshwater resources.

Although we continue to advocate for the protection of water resources, we still do not know what the consequences will be if we continue to waste water without protecting it.

Just look around us, there are many little children who play with water guns, and they probably think it's fun to play in the water. Running around with a water gun every day, spraying around, and having a special time. They don't even care if they become "soup chickens", they don't know how much water they will waste.

It doesn't matter if we waste a little water every day, if our 1.3 billion people in China waste one drop of water a day, then our country will waste 1.3 billion drops of water a day, which is not a small amount.

1. Start from yourself and don't destroy water resources with others. It is also necessary to start with the family, so that the family understands the danger of destroying water resources, so that they do not destroy water resources. And let others protect water as you do.

2. Be diligent and thrifty in using water at home. Do not pour out the water after washing the vegetables, it can also be used for watering, watering flowers, etc. Parents should also be asked to conserve water at work.

Don't think it's a worker. Water can be wasted. This is a sign of improper water conservation.

It is also a sign of irresponsibility.

3. If you see someone deliberately destroying the water source, you should bravely persuade him and explain that destroying the water source will bring us great danger. And let him protect water resources in the future. Those who refuse to listen to dissuasion, and the circumstances are severe, should be reported directly to the relevant departments, and the law should be used to punish them.

4. In school, we should be a role model for Yuntanla students and a role model for them. Let students also have a sense of responsibility to protect water resources. Like mopping the floor, students waste a lot of water when they are making mops.

If you waste it like this, you have to waste a lot of water! Two pools of oaks should be set up in the place where the mop is flushed, one for the dirt and one for cleaning. When the students finished mopping the floor, there was a lot of dirt on it, so they went to the pool to flush the dirt and wash it off.

I rinse it in a clean place. In this way, a lot of water is saved, which not only saves water, but also flushes the mop clean, which is really a double win!

Friends, let me take action and make an effort to protect water resources and nature! Let us start from the beginning, and develop the awareness and habit of cherishing, saving and protecting water, not only for mankind, but also for the tomorrow of each of us! Don't let that last drop of water be our tears.

The source of life, water, with which all things in the world come into being; With it, there are beautiful mountains and rivers of the motherland; clear streams; Clear blue oceans and lush forests.

We often say that water is the source of life, the blood of industry, and the blood of cities, but in daily life, the member of "water saving" seems to have been eliminated by people for a long time, and human beings have invisibly developed a habit of wasting water, constantly hurting our dearest friend - water.

Once, the sky was still blue, the sea was still clear, and thousands of plants and animals lived happily in the embrace of the ocean, living a happy life.

Gradually, the nightmare came.

More and more smoky factories have appeared around us, and the once cheerful streams have been mercilessly filled, resulting in the towering buildings of today. The sound of the "whooshing" of the water no longer exists. And now people only know that "every inch of land is valuable", but they forget"Drink water and think about the source".

Not long ago, I saw a scene in a TV series where a hotel waiter just put a drink bottle full of water in the toilet tank in every room. This may seem like a simple move, but it saves a lot of water for the hotel.

And in our lives, some people don't know to turn off the faucet after washing their hands, and even if they reach for it, they don't close it tightly. When you hear "tick, tick, tick" one day. When the water drops sound, please stop your hurried steps, do what you think is insignificant, and reach for the faucet to turn it off, you know?

The sea is also made up of thousands of droplets. Please use your own behavior to influence the people around you, as Mr. Lu Xun said, "Hope is indifferent, it doesn't matter, this is the road on the ground." In fact, there is no road on the earth, but when there are many people walking, it becomes a road.

Just as we save water, if we save "one drop of water" per person, then our "global village" will become extraordinarily beautiful.

"Water" is like human life, when water resources are gradually scarce, it is like human life slowly passing away, maybe on that day, we will understand what it means to "want to cry without tears" and "difficult to collect when covered with water". All that remains is regret and regret! Don't let the last drop of water become a human tear!

Summary. It's an eco-friendly advertisement: the last drop of water on earth will be human tears!

Original words: It was a brief paragraph: "Some of the world's major rivers are in danger of drying up due to climate change, pollution and other factors; About 41% of the planet's population lives in these watersheds, at least 20% of the 10,000 species of freshwater animals and plants are extinct, and 700 million people are suffering from water scarcity in 43 countries around the world, with more than 3 billion people suffering from water scarcity by 2025.

But that could be a terrible conclusion, that the last drop of water on Earth could be our human tears.

It's an eco-friendly advertisement: the last drop of water on earth will be human tears! Original words:

It was a brief quote: "Some of the world's major rivers are in danger of drying up due to climate change, pollution and other factors; About 41% of the planet's population lives in these watersheds, at least 20% of the 10,000 species of freshwater animals and plants are extinct, and 700 million people are suffering from water scarcity in 43 countries around the world, with more than 3 billion people suffering from water scarcity by 2025.

1. Water is one of the most basic conditions for human survival and development.

2. Human activities consume a lot of water, but freshwater resources are not abundant, and human production and life also cause pollution of limited freshwater resources.

3. Save water and protect water resources.

The biosphere is a general term for surface organisms, including microorganisms and their bottom-up environment. The biosphere encompasses all living things and their living environments. In the largest ecosystem, the destruction of any link will have a direct or indirect impact on human life, and if the biosphere is out of balance, it will be difficult for humans to survive on the planet.

It is impossible not to kill, the meat we eat is to kill the life of cattle, sheep and pigs, and properly killing these animals that are not frequent animals and reproduce quickly is not a big harm to the environment.

The protection of the biosphere is of great significance, and to sum them all up, in a word, is for the survival of human beings themselves.

The biosphere is destroyed, even if human beings can survive by luck, without other organisms, human beings will not only immediately lose food**, but also, because the biological balance is broken, biodiversity is lost, causing a series of chain reactions such as air pollution and water pollution, human beings will slowly hang up. Man is not a creature that dominates the earth, and he cannot dominate other creatures, because we depend on them for survival.

Humans depend on other organisms for survival, and other animals depend on the environment for survival. In the final analysis, it is human beings who wantonly destroy the environment in which they live, but it is also inevitable that the environment will be damaged by natural factors such as volcanic eruptions. So, what we can do is not just to protect the animals that are most frequently affected – the most important thing is to manage the undamaged environment, and repair the damaged environment, so that we can avoid more animals from becoming extinct.

What we can do is not something shocking, but something that is at hand. Throwing away a paper towel, passing by a store when you're thirsty, wasting a plastic bottle less, spitting out a piece of gum, walking a few more steps and using a motor vehicle are all things we can do easily and should do.

Protecting the environment starts with you and me, starting with the little things. It is not that human beings are generous for the sake of the whole planet, and it is selfish to say that human beings protect the environment for the sake of human beings.

If we don't take measures to cherish every drop of water, save water, protect water resources well, and not be polluted, in the end water resources will be depleted, or because of serious pollution, we can't use them at all, even if we leave tears of remorse, it won't help.

It is to let human beings not waste water when they still have water available, so as not to deplete water resources, and when there is no drop of water, the only water that exists in the world is human tears.

Hehehehahaha
