Water is an indispensable thing for people, and it is something that the whole world cannot live without. All living things need water, and they can't live without it. Don't look at the inexhaustible water of our sea, there is water, everyone will not be happy.
No one is bothered by the lack of water. In fact, there are some places in our country that are very short of water, and now, isn't the south-to-north water diversion being carried out? Xinjiang, Inner Mongolia and other places where there is not much water have become deserts.
Indeed, in people's impressions, water is everywhere and serves people's production and life. It is the blood of industry, the lifeblood of agriculture, and the most indispensable assistant in life. In short, water is the treasure we live on.
Moreover, according to the survey, the earth we live in also has an alias called "Mercury", and as the name suggests, our earth is full of water. But 97 percent of this water is seawater, and half of it is in the inland sea and salt lakes. The root of fresh water is rain and dew, and only 10,000 cubic meters of water fall to the land every 49 years, and 2 3 of them are transpired by plants or evaporated by the ground, and only 1 3, that is, 10,000 cubic meters of water can be used by human beings.
Is this little water enough for us? The answer is no.
In this case, why don't people step forward and turn off the tap when they see the tap water flowing "rattling"? Why do people always have to dump all their industrial waste into the clean river? Why can't we stop wasting water and cherish every drop of water?
In fact, isn't it harmful for human beings to waste and pollute water resources without regret? Therefore, we need to use water recycling. Using a natural desalination device to desalinate seawater is environmentally friendly and cost-effective.
The problem of water source is solved, how to use it? People should invent more water-saving products such as "electrolyzed water molecular washing machines", so that they can truly save the source of life. However, not only machines, but also humans themselves have to contribute.
For example, the water used to wash vegetables can be used to flush the toilet; The water for bathing can be used to mop the floor; The water used to wash rice can be used to water flowers and so on. Although there are many water-saving products now, the most important thing is to rely on people themselves – not to waste, not to pollute water resources, so that water resources can be better protected. Yes!
Wake up! If we don't cherish water resources, if we don't strengthen our awareness of protecting water resources, then the last drop of water on the earth will be our tears in the future.

The essay on cherishing water resources should first be written around the theme of water, and it is necessary to write about saving water. Then secondly, we should give a few examples to prove the importance of water, which is indispensable in daily life, such as industrial water, and the most indispensable thing in domestic water is water resources and some of the importance of water resources. Secondly, what should be done to save water resources?
For example, how do you reflect some small details in ordinary life? For example, the size of the faucet and the reuse of water resources are described. Then there is some pollution of water resources, everyone is responsible for protecting the environment, and the waste of the factory and the garbage in daily life, please do not discard it at will, so that you can also protect water resources and cherish water resources.

If plants run out of water, if fish run out of water, if humans run out of water, then what will the world be like? There would be no humans, no plants, no animals, and the whole world would perish. And that's all because it's just a small drop of water.
About 8 litres of water are wasted in one flush of the toilet and about 40 litres in a day. And we can save 20 litres of water with a little effort: you can put a large bottle full of water in the tank; You can also use the water to wash the bowl and wash the rice.
In this way, it is convenient and economical. If there is extra water such as washing clothes, shabu mop, etc., it can be used to water flowers and brush pots, which is a double win. A drop of water can save a person; A drop of water will support the world.
Even though we are only elementary school students, we also need to conserve water.
You may be asking, "Why save water?" "Because there are many poor children now, who do not drink water every day when they want to, as we do, but watch others drink and they themselves do not drink.
How many people in water-poor mountainous areas are desperately longing for a glass or even a drop of water to moisten their dry tongues! How much every arid region needs water, but those who pollute the water, have you ever thought about the feelings of others, and you keep discharging wastewater into the river for others to use? The river has helped us, and we should help the river because it keeps us alive.
Do you know? If a faucet leaks only one drop of water per second, it can add up to a staggering 360 tons in a year; If it doesn't rain, we can only use about four years of fresh water on the earth. If you don't eat any food, people can live for a decent amount of time, and some fat people may even live for a year; But people who don't drink water can only live for more than 10 days at most; It takes more than 200 tons of water to make one ton of steel, more than 20 tons of water to refine one ton of gasoline, and even one kilogram of water to make two kilograms of bread.
In the arid regions of Africa, many people are dying of thirst because of lack of water. There is a saying on TV: don't let the last drop of water in the world be our tears.
Life is precious, but we must not be without water. If a person can save 1 drop of water in his lifetime, then there are 681807 people in the world who can save 681807 drop of water!
Please cherish the water source and protect the water source!!
Writing about the preciousness of water, the ratio of water to the ocean, from this side reflects the preciousness of water.
The source of life - water and water, a very ordinary thing; Water is a precious thing. Water is the origin of our life, and it is also the most basic resource of our life. Although the global water area is larger than the land area, 2 3 of the ocean's undrinkable salt water and 1 3 of the drinkable freshwater. >>>More
