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!
