When I first saw the sea, it was still very small, and I was amazed by the vastness of the sea, and a concept naturally arose in my mind: water is endless, inexhaustible, and inexhaustible.
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 a precious treasure that we rely on for survival, and according to the survey, the earth we live in also has an alias called "water ball", 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 do people always turn a blind eye when they see the tap water flowing "rattling" and are reluctant to take a step forward and turn off the tap? Why is it that when some people throw garbage into rivers, seas and lakes, they can't imagine how polluted the water is? Why don't people feel sorry when industrial sewage flows into rivers, seas and lakes and sees the originally clear water turn into sewage?
Why when...
In fact, human beings are now slow to commit suicide, they do not regret polluting and wasting water resources, but how precious water is! If we don't cherish water now, water will be as precious as oil in the future.
Therefore, we need to do a good job in 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 machine", "electrolyzed water molecular washing machine" uses the principle of electrolysis of water molecules, so that the oxygen atoms in the water molecules absorb the booty in the clothes, and the electrolyzed hydrogen atoms can be used as fuel for environmentally friendly cars, which does not damage the clothing fibers, but also provides power energy for the car, and also does its best for the cause of environmental protection, why not?
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, the last drop of water that will fall on the earth in the future will be our own tears. Agree with 2

"Building a conservation-oriented society" is a slogan that we cherish and conserve resources. But how can we really conserve resources? Why is saving highly recommended? Hear what I have to say!
Let's start with water resources. China's total water resources are about one trillion cubic meters, ranking sixth in the world, with a per capita water volume of more than 2,100 cubic meters, accounting for only a quarter of the world's per capita level, belonging to a water-scarce country, and more than 400 of the country's more than 600 cities are short of water. In particular, the water shortage in the western region is very serious, and in some mountainous areas, it is very difficult to even drink water for people and livestock.
Our country is facing a serious problem of water use, so we must cherish water resources and save water. For example: after using up the water, tighten the faucet, so as not to cause the waste of "a river of clear water flowing eastward", if you find that the faucet is broken, you should repair it in time to avoid losing a lot of water, and don't underestimate the discarded battery, because a button battery will pollute 600 tons of water, if you throw it into the water, the water will not be drinkable.
We should collect the battery and send it to the first station, so that we can not only avoid polluting the water source, but also make the battery get the first place, killing two birds with one stone. You can't just talk about it, you have to take action!
It's not just about saving water, it's about saving forest resources. The total amount of forest resources in China is insufficient, and the forest coverage rate is only, which is equivalent to the average forest coverage rate in the world; The per capita forest area and per capita forest stock of the country are less than a quarter and one-sixth of the world per capita level, respectively. The quality of the forest is not high, and the average volume per hectare is only cubic meters, which is equivalent to the world average.
That's what Forest Resources is warning us about! We must economize on the use of forest resources, first of all, we must not throw away manuscript paper, nor take unwritten paper to fold small handicrafts such as airplanes, let alone cut down indiscriminately, trample on flowers and trees at will, plant trees, and take care of flowers and trees; Do not use disposable items such as paper cups, wooden blocks, etc. At school, we set up a "green bank" and pick up confetti, handkerchiefs, etc., that were previously discarded.
When eating out, bring your own spoon and chopsticks. Students, let's take action together to conserve and use our limited forest resources.

Hello! The survey report on human resources in the exhibition industry is divided into three parts: introduction, current situation and countermeasures. The introduction mainly summarizes the purpose, theme, method and conclusion of the investigation (abbreviated); The current situation is mainly to describe the main situations (including good and bad) found in the investigation and their reasons (write in detail); The countermeasure is to put forward opinions and suggestions to solve the problem in a targeted manner.
First, the questions raised in life have.
Many uncivilized phenomena. This time, our group conducted an investigation on some uncivilized phenomena in society. >>>More
Another important purpose of going out for social practice teaching is to cultivate students' love for China's excellent traditional culture, so that students can get out of the cultural tradition obtained from books and enter the field art investigation of magnificent rivers and mountains, and educate students to understand, accept, and love Chinese culture. Everywhere they go, students are purposefully guided to observe the evolution of local culture, folk customs, folk art, and historical and cultural relics. Observe and appreciate the scattered and orderly mountain buildings, collect local folk characteristic image materials, pay attention to the study of different regions, residential life, furniture styles, and accumulate image materials for future artistic creation. >>>More
