The earth is a world with many resources. With the progress of human science and technology, we use a lot of resources. However, if we humans don't know how to save resources, we will reduce the resources of the earth ... "Nature sometimes breeds things, land makes money limited, but people's desires are infinite." Bai Juyi, a poet in the Tang Dynasty, has a clear understanding of the relationship between ecological resources and human survival, which is still of positive significance. The era we live in is facing serious problems such as lack of resources and environmental pollution. For the sustainable development of our living environment and economy and society, conservation and environmental protection are imminent. Every one of us holds precious "resources" and the "lifeline" of the development of the Chinese nation. The invention of paper is a great contribution to human civilization. At present, there are about 500 kinds of paper produced in China. Now, we have the necessary stationery paper in our life. Paper can be seen everywhere: textbooks, exercise books, draft books, etc. Many, many. However, many students waste paper and litter everywhere on campus. Let's act together to save paper.
Saving paper means planting trees.
From study to life, we can't live without paper, and the raw material of paper making is mainly the fiber of plants such as bark, but because people cut it blindly. There are fewer and fewer trees now, so we should save paper. It is everyone's responsibility to start from the little things around us.
The concept of "saving paper" seems a bit far away from saving water and electricity for us. Few people know what is the direct relationship between saving paper and protecting the ecological environment. Each of us uses paper every day, using different types of paper. Have you counted them? How many sheets of paper do you use every day? How much paper do you need a week? How many sheets of paper do you need a month or even a year? The result is amazing. Where does a piece of paper come from? Paper is changed from a tree. It often takes decades for a tree to be used by human beings. Human beings are heartless. With the sound of a chainsaw, the tree that had grown for decades fell to the ground. Wood was transported to the paper mill and turned into pieces of paper. Paper has brought convenience to human beings, but at the same time it has also brought great influence to forests.
Trees can not only be used to make paper, but also provide wood. A large area of forest can conserve water, prevent water loss and purify the air. If there are no trees, there will be no oxygen, and there will be no place for human beings to live. The harm of forest disappearance is great: the Loess Plateau was originally a forest, lush and endless, with green waves rippling. However, due to the destruction of people, the Loess Plateau has really become a plateau with only loess, and the earth has taken off its coat and exposed its yellow skin, which is very sad. Moreover, because there are no trees, a lot of soil is lost, which leads to the extremely high sediment concentration in the Yellow River. How can human beings be indifferent to such great harm? Afforestation is imminent.
Forests are factories that make oxygen. It can absorb harmful substances, conserve water and soil, and conserve water. The canopy is like an open umbrella, which can intercept 10~20% rainfall. The water storage capacity of 50,000 mu of forest is equivalent to a small reservoir of 6,543.8+0,000 cubic meters.
March 12 every year is "Arbor Day". On this day, many people take tools to plant trees. Now the forest coverage in China has increased. This is the result of human introspection, which is gratifying. However, although the forest coverage rate has increased, it is still very low. Therefore, afforestation is an arduous task and an eternal task for mankind. Now it's summer. Although the best time for planting trees has passed, we can sow the seeds of "saving paper" in our hearts and plant trees. By the next spring, these trees will sprout and grow tall. We can go outdoors with tools, sow the seeds of trees on the earth, take good care of them and make the motherland full of green!
Saving begins with every piece of paper.
How much can an extra piece of paper be worth? It is inevitable that some people will whisper like this. In fact, saving is equal to creating wealth. I once read a message in Xinmin Evening News: At present, every ton of paper produced in China consumes 7 trees, 100 cubic meter of water. If everyone wastes a piece of paper every day, the whole country will waste 2700 tons of paper and 270 thousand tons of water. As long as most enterprises can accept double-sided copying and intensive gospel, A4 will save at least half of the paper fertilizer. What amazing news this is! Do you save paper? Do you know how to save paper? Many people only use one side of the paper and throw it away after use. They think that as long as they have money, they can buy countless pieces of paper, and they don't care about one or two pieces of white paper at all. But what a waste! If everyone wastes like this, will there still be forests in this world? Therefore, in order to protect forests and protect green plants, we should strive to be a thrifty person. Use paper as much as possible and recycle it as much as possible.
According to relevant data, every 5000 A4 paper saved is equivalent to saving wood 1 m3. If everyone in China saves 1 sheet of paper every day, it will save 474.5 billion sheets of paper a year, and a 20-year-old tree can make 3000 sheets of A4 paper. In this way, 158 1666 trees can be cut down less. It can be seen from this that saving paper is also afforestation.
Saving paper is a good way to protect the earth's resources, but how should we save resources? Here are some tips to save paper, you might as well try them:
1. Both sides of white paper and exercise book can be used for writing, drawing, calculating, etc. Used paper can be used for origami, which is more economical.
2. If the origami is not folded, you can tear it off and fold it again. Don't throw it away casually.
3. Wipe your hands with a towel at home and use less napkins.
4. When eating out and wiping your mouth with a napkin, try to spread out the paper and reduce the number of sheets of paper.
5, drink tea cups, do not use disposable paper cups.
6. Waste newspapers and books can be recycled. Don't throw them away.
7. Don't throw away cardboard fragments. They can be used to decorate other things.
These are my usual ways to save paper. As long as you pay attention, you can also find many tips to save paper.
Students, a page is a page of gold. Cherishing a piece of paper is tantamount to planting a tree. Are you far from disposable paper cups and disposable wooden chopsticks? Have you ever written on the back of a piece of paper? Have you ever wrapped the cover of a book with old calendar paper? Do you separate waste paper from garbage? We only have one earth, so let's start from ourselves, save every piece of paper and cherish and protect our ecological environment. Saving a piece of paper may save a big tree or even the whole forest ... saving is not only a virtue, but also a responsibility.
Since ancient times, the Chinese nation has always regarded thrift as a virtue worth promoting. Everyone can stop wasting things in life, and places to save can be found everywhere. If we act together with our 65.438+300 million compatriots to truly protect the environment and save resources, the strength it gathers will not only be the support for our country to move towards the future, but also a gift from our nation to the earth and mankind. Come on, for tomorrow's tomorrow, let's start saving today! Finally, I want to say something that everyone should remember, that is, saving paper is our common responsibility. Let's join hands to create a conservation-oriented society.
