Nanjing is a beautiful city. Our "Young Eagle Holiday Team" went to Crescent Lake Park to do environmental protection activities. We also promote environmental protection knowledge to tourists. Although our strength is small, we also hope that our beautiful city will do its part. Let's protect our beautiful city together.
There is a French fable: "There is a big lily in the pond, which grows twice as fast every day. If it is not restricted, it will cover the whole pond within 30 days and suffocate the creatures in the water. Humans won't realize this danger until they are 29 years old-because lilies have covered half the pond. However, how much time is there to save the pond?
Not only water resources are polluted, but also clean air, one of the three elements of human life and health, is doomed. Reducing pollution and purifying the air, "Give me back my blue sky and red sun" has become the common aspiration of people all over the world.
With the rapid development of modern science and technology, we humans have invented vehicles such as cars, planes and trains. Although this is a great pioneering work in our history, it has also brought us great harm. Carbon dioxide emitted by factories and cars is a colorless and odorless highly toxic gas, which is not only harmful to human health; It also brought huge losses to agricultural production. A small amount of carbon dioxide gas will affect the life function of plants. Once the rice is fumigated, the yield will drop by 85%. 9%。 From this perspective, we must protect and cherish the atmospheric resources.
The levee of a thousand miles was destroyed in the ant nest. Now the earth is sick, riddled with holes and ugly. Do we realize that the time to try our best to save the earth is short?
Our earth is so lovely and fragile. Humans are doctors. In order to save the earth on which human beings depend, and also to save ourselves, let's take action and protect the environment together!

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. It's summer. Although the sowing season 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!

The earth is the home of human beings and a big place where we live. With the improvement of the level, while people enjoy it, they also deteriorate our living environment unconsciously. Man is a member of nature, and his survival cannot be separated from nature. All kinds of natural resources are interrelated. On the one hand, it will be destroyed, on the other hand, it will be affected, thus directly or indirectly threatening the survival of mankind and punishing mankind. Therefore, we should protect nature.
Some natural resources are renewable and can be contributed to people for a long time. However, due to uncontrolled exploitation and abuse, the mineral resources on the earth are rapidly exhausted. They think that their interests have risen and their lives will be better, but in fact they have brought disaster to everyone and their future. How beautiful nature is. Qian Shan is full of water, tall buildings, flowers and trees, blue sky and green grass, but people are still unwilling. In order to survive better, they continue to use and transform nature. However, the unreasonable use and transformation of nature destroys nature and brings disaster to the future of mankind.
Our natural resources can be divided into renewable resources and non-renewable resources. Natural resources are characterized by availability, integrity, variability, uneven spatial distribution and regionality. They are the material basis of human survival and development, the source of social material wealth and one of the important foundations of sustainable development.
Natural resources can be divided into biological resources, agricultural resources, forest resources, land resources, mineral resources, marine resources, climate and meteorology, water resources and so on.
1) Environmental resources, such as sunlight, geothermal, air and natural water. This kind of resources is relatively stable, but the utilization rate is obviously reduced. If properly developed and carefully protected, water can be used continuously for human beings.
2) Biological resources, such as animals, forests and grasslands. After being used by human beings, such resources can be reproduced through their own production and reproduction. If it can be developed and utilized reasonably and managed scientifically, it can also be used for human water continuously.
3) Land resources, including agricultural land and urban land. It is the object and means of labor for human survival.
4) Mineral resources, including energy and various minerals. It was formed after a long geological age, and its reserves are limited. After development and utilization, it cannot be regenerated, and some will be less until it is exhausted.
In order to protect natural resources, we should:
1, conveniently turn off the tap.
2. Use less plastic bags
3. Use less disposable tableware
4. No spitting or littering.
Step 5 buy green food
6. Use less wooden pencils and more mechanical pencil.
7. Make full use of white paper and try to use recycled paper.
8. Refuse to eat wild animals or use wild animal products.
9. grow more plants
10, don't keep the TV station captain waiting.
Let's work together for our home!
