We and the surrounding environment

Today, I walked around the campus After walking around, I found that there are quite a lot of garbage on campus, including plastic bags, shredded paper, ice cream wrappers... These caused me to reflect - we live in nature every day. Live in the midst of all this beauty. Mother Earth generously provides us with various unlimited and limited resources, allowing us to have "enough food and clothing", but human beings are not only dissatisfied, but also destroy Mother Earth. With the changes of the times, people's requirements have become higher and higher. They cut down big trees to make wooden boats, disposable chopsticks and other things that are beneficial to human beings, and these are always a flash in the eyes of human beings. However, what a huge damage to nature. Although people are now promoting environmental protection and calling for green everywhere, this has not stopped the vandals. Big trees are still falling down and the area of ????the desert is still expanding. Now, due to humans cutting down trees in large numbers, deserts are now devouring nature and the entire earth, people! Are you just willing to watch large areas of green being destroyed? This kind of plastic is difficult to rot and is called "white pollution". The used waste is very difficult to process. If it is buried, it will destroy the soil structure; if it is burned, it can produce toxic or highly toxic gases such as fluoride and hydride, which will harm humans and animals. I never thought that a small plastic bag could be so harmful. Before people realized the disaster they had sown, nature had already struck back angrily. The oceans and atmosphere have given humanity a warning. No matter which sea area in the world, no matter how far it is from industrial and agricultural activities, from Arctic Iceland to Antarctic continent, harmful substances are detected to varying degrees everywhere, alas! Where has the ocean I used to love gone? Green as blue, has it become a memory? I appeal: Don’t destroy our own home anymore. It is everyone’s responsibility to protect the environment. Protecting the environment starts with me, starting from now!
We and the Surrounding Environment
A series of environmental problems such as the sharp decrease in forest area and atmospheric pollution have affected human survival and economic development. Strengthening environmental protection is an important measure to implement the sustainable development strategy. Strengthening students' concept of loving the home of mankind and protecting nature from pollution is a foundational project to promote and promote environmental protection work.
A series of environmental problems such as the sharp decrease in forest area and air pollution have affected human survival and economic development. Strengthening environmental protection is an important measure to implement the sustainable development strategy. Strengthen students' concept of loving the home of mankind and protecting nature from promoting and promoting environmental protection. Forests are the cradle of life.
The forests that once covered 2/3 of the earth’s land area protected and nurtured thousands of lives, including the ancestors of humans. In ancient times, human ancestors lived in forests, using them to resist cold winds, using leaves as clothing, filling their stomachs with wild fruits, and building blocks as nests. They drilled wood to make fire and hunted animals with sticks, relying on forests to develop human civilization.
Today, the global forest coverage rate is less than 27%, and the forest area is still decreasing. Human beings have finally tasted the bitter consequences of their predatory use of forests: land desertification is becoming increasingly serious. More than 1.2 billion people around the world are directly threatened by desertification, of which 135 million are in danger of losing their land in the short term; fresh water is in short supply, and by 2O25 Fifty countries are experiencing serious water shortages; air quality has deteriorated, and the sharp increase in carbon dioxide has caused global warming. By 21O0, the melting of glaciers will raise global sea levels by 144-217 centimeters, and many coastal areas will be wiped out. Disasters; a large number of wild animals and plants become extinct, and at least one creature becomes extinct every hour around the world.
Vigorously carrying out afforestation activities can effectively delay and prevent the occurrence of the above disasters. Due to its tall shape, complex multi-layered structure, huge intertwined root system, wide distribution, large area, high productivity and long life, the forest has a huge impact on the surrounding environment during its own growth and reproduction. It affects a series of physical and biological conditions and has strong and lasting ecological and environmental effects, regulating climate, conserving water sources, preserving soil and water; preventing wind and sand, preventing and reducing natural disasters, purifying the environment, eliminating noise, etc. Function.
The forest is known as the "green reservoir". Forests are also called "human lungs" because of their great ability to decompose carbon dioxide and release large amounts of oxygen. A 40-meter-wide forest belt can reduce noise by 10-15 decibels, and green streets can reduce noise by 8-10 decibels. It can be seen that forests also have the function of "sliding noise". The function of forests in preventing floods is well known...
Afforestation can not only effectively improve the ecological environment and make our place of residence better, but also has huge ecological benefits. Take Japan as an example. The national forest coverage rate in Japan is 65%. For this reason, the annual water storage capacity of forest soil reaches 230 billion tons. The forest prevents 5.7 billion cubic meters of sediment loss, inhabits 81 million birds, provides 520 million tons of oxygen, and absorbs 5.2 million tons of oxygen. 69 million tons of carbon dioxide.
The value of these forest ecological benefits alone is equivalent to 13.8% of Japan's annual gross national product, 2.6 times the output value of agriculture and fishery in the same year, and the value of timber output H. times.
Afforestation is one of the most effective self-rescue measures for humans in the face of huge natural disasters. In order to make the earth more green and a barrier to life, let us take action. Each of the 1.2 billion Chinese people contributes a little green to the motherland, which will create a miracle in the history of world afforestation
