Now, even the South Pole has been polluted and destroyed. Therefore, the earth has lost the last piece of pure land. Mount Tai used to be a good place for people to watch, but now it has also become a protected area.
And we can only stand by and watch this beautiful and fragile earth disappear forever? From then on, can we see the wind blowing and grass watching cattle and sheep, and can we see horses running under white clouds? Although we are only primary school students, we can still make some contributions to our hometown and make Dingxi rise in hope.
Some students may know that there is a Lop Nur on the edge of Taklimakan desert, which is a vibrant oasis. There will be fresh air, desirable environment, full of green and jungle all year round, which makes a few people living there rekindle their hopes for an oasis in the desert. But who knows that the holy land, which lasted for hundreds or even thousands of years, was actually disappeared and destroyed by the fools there. The death toll is increasing one after another, and the forest has been seriously polluted by the air because the rotting bodies are not buried, and the forest is disappearing day by day. Through the sunshine that almost scorched the land of Lop Nur, you can vaguely see the pain of Lop Nur! Is missing, missing the past cattle and horses, green mountains and green waters; It is sighing, sighing yellow sand and Wan Li, dead trees and dead branches; It is the yearning for the source of life and the root of all things. However, human beings, a huge water-absorbing ghost, cut off its last glimmer of hope. As a result, the long green embankment built with the desire for life collapsed. ...
April 22nd is a festival of the earth every year. It has been 30 years now. Because of the "three wastes" pollution (waste water, waste gas and waste residue) and the "top ten pollution", a large number of people all over the world get sick, disabled and even die every year. However, white pollution is free. It runs amok in the sky, piercing the clothes of Air Brothers and Ozone Brothers, making the sand in the desert fly forever and disturbing people's lives. Uncle naturally did not dare to object, and left people in a hurry.
If we can't stop it, white pollution will severely punish mankind. In the end, not only rare animals and plants, but also human beings will eventually become extinct in the desert.
Students, we can't live without the earth. We are bound by the same fate. Uncle nature expects it to go home. Mother Earth entrusts the heavy responsibility to mankind, because only we can save the happiness of the earth and mankind: let the green stop sighing, let nature stop crying, let the scars of Mother Earth disappear, and make the earth more beautiful, strong and lovely tomorrow!
Now the earth is all yellow, and the green is greatly reduced. What happened? It turns out that this is because people cut down a lot of trees, which not only makes birds lose their homes, but also causes collapses and floods. Without trees, our earth seems to have no pillars.
Now all the shops are following our hobby, producing a lot of soft drinks. The "coat" of soft drinks is canned, which is a kind of pollution. Roads, parks and even schools have become their homes. Some cans are made of aluminum, which is also harmful to human body.
Do you know that?/You know what? Do you know that?/You know what? Waste batteries contain a lot of heavy metal pollutants-chromium, lead, mercury and so on. The pollution caused by waste batteries is slow and far-reaching. When they are mixed with ordinary household garbage, under certain conditions, a series of chemical reactions will slowly occur, releasing toxic substances, which will pollute the atmosphere when burning and pollute groundwater or rivers and lakes when infiltrating underground; Once it enters the soil water source, it will enter the human body through the food chain, damaging people's nervous system, hematopoietic function, kidneys and bones. Therefore, it belongs to hazardous waste. Tests show that the amount of water polluted by mercury batteries exceeds the sum of a person's lifetime water consumption.
In the past, the river was crystal clear and small fish could be seen. Now the factory regards this river as a good place to discharge sewage in order to improve efficiency. The river was polluted by sewage, and passers-by quickly left.
Saving water means protecting our environment, that is, saving resources. We should take our own practical actions to protect the environment. The simplest way is to start from ourselves and pay attention to saving water. For example, turn off the faucet at any time after use; Water the flowers with vegetable washing water, rinse the mop and flush the toilet. Don't think that a few drops of water in the tap are nothing. If a faucet drops a drop of water every second, it will lose 36 cubic meters of water a year. If a household saves one side of water every month, how much water does the whole country save in one month?
Fortunately, now people have realized that the earth is polluted, and everyone has taken action. I hope those who haven't acted will bend down and pick up the paper on the ground, so that our tomorrow will be more beautiful and tidy!

The earth is rich in water resources reserves, and there is a saying that the land is divided into three parts and the water is divided into seven parts. Then why repeatedly emphasize "save every drop of water" and "don't let tears become the last drop of water"? Is it necessary? Yes, of course. The so-called "three points of land and seven points of water" includes ocean water, glacier water, groundwater, lake water, river water and other water bodies. Sea water accounts for 96% of the earth's total water. 53%, because it is salty, it is not suitable for drinking and domestic water. We only use fresh water resources. Freshwater resources account for 2. 68 out of 53%. 69% glacier water and 30%. 06% of underground fresh water, due to technical reasons, only a small part of fresh water resources are used by us: lake fresh water, river water, shallow underground fresh water and so on. Therefore, the fresh water resources that can really be used by us are very small. It is no wonder that the CPC Central Committee has called on us to save water. In recent years, due to the enhancement of human activities, a lot of sewage has been discharged, which has polluted water bodies and reduced our water consumption.
Take the Yellow River as an example! It was not originally called the Yellow River, but called Dajiang, which is our mother river like the Yangtze River. Due to the felling of trees on the loess high slope, soil erosion turned yellow from the Tang Dynasty, and now we are "a bowl of Yellow River water, half a bowl of sand".
Similar to the Yellow River, the water in my hometown was originally very clear. When my father was a child, the river was crystal clear, and it was easy to look directly at fish and fine stones. In summer, dad plays with his partners and keeps up with the water kung fu competition. In recent years, factories have been set up in my hometown, and everyone has built new houses. The living standard has improved, but this quality is not as good as it used to be. Sewage is discharged indiscriminately, garbage is dumped indiscriminately, and a good river has simply become a stinking ditch. So no one will come here to wash vegetables and clothes, only dirty things like pesticide bottles will be cleaned. The old country river has left. I remember that once my father wrote an essay called Lost Dreams, which was about this river.
Man is the spirit of nature. He thinks he is the master of all things and can transform nature at will. It took hundreds of millions of years for nature to establish harmony, and it took less than a hundred years for human beings to collapse. You know, other animals also have the right to live. Water is one of the most basic substances needed by all life. In order to protect life on earth, the most important thing is to protect water first, the water we live in.
Take the protection of water resources as our most glorious mission to complete and realize!

Everyone has his own home, the forest is the home of wild animals, the pond is the home of small fish, the sky is the home of small clouds, and the earth is our human home.
The earth has given us water and forests, beautiful environment and fresh air. But how do we humans treat our homes?
Listen to mom and dad, the earth used to be beautiful, full of beautiful scenery, birds and flowers, fresh air, making people relaxed and happy. But now, what has the earth become? Because of human selfishness, they plundered forests and water resources, did not cherish them, lavished and abused chemicals, resulting in a series of ecological disasters. As far as I know, factories and power plants all over the world emit 5 billion tons of carbon dioxide into the atmosphere every year; The emissions of harmful gases such as sulfur dioxide and carbon oxides are also quite large. There are many kinds of exhaust gases entering the atmosphere, including 100, which have caused harm and attracted people's attention. A large amount of waste gas entering the atmosphere will inevitably destroy the original chemical organization and properties of the atmosphere and cause great harm to the human environment. It can make us die of lung cancer, make the world face the danger of warming, melt icebergs, reduce the baldness of the whole earth, make a large number of crops migrate with climate change, and make many crops reduce production. In a word, air pollution is a disaster for mankind.
Protecting the environment is everyone's responsibility! Although we are only primary school students now, we can't make a great contribution to the environment of all mankind, but we can start from the little things around us and protect the school environment. Students, we are the masters of 2 1 century, and environmental awareness is the symbol of modern people. We should have a sense of responsibility for the times and make our due efforts to beautify and purify the campus. "Don't do it because of small evils, and don't do it because of small goodness." Let's protect and cherish the earth, our common home, let the breeze blow the green willows forever, and the clear water will always accompany Cangshan!

A gust of wind rolled up the dust all over the sky, and the raised plastic bags were fiddled with by the wind. My heart always thinks: Please give me a green home! Okay？
I saw the dust flying all over the sky polluting the green home, and a pile of dust polluted the clear and sweet spring water. In addition, people chop down trees and throw "white garbage" ... making it difficult for green to resist the yellow desert, and the "plan" of desert pollution has been taken. If human beings don't take timely measures to plant trees and green the environment for the earth, it will be too late to plant trees in the desert, and all life will become a desert, which is impossible. Dude, open your eyes! Planting trees for nature! Make your home better!
Soon, the county government launched the "urban and rural cleaning project", planting trees to green the environment and destroying the "plan" of desert pollution. Now the area of green space is three or four times that of desert! The air is fresh, the forest is lush and the grass is beautiful! I hope it will be better in the future!
There is only one earth for human beings, and the ecological environment of the earth is the most basic condition for human survival. Protecting the earth's ecological environment is the basic guarantee for the sustainable development of human society. Protecting life on earth, especially green plants, protecting life on earth and protecting an earth that belongs only to human beings is the most sacred mission of the earth people.
Give me back a piece of blue sky and a piece of green land. Let's act together to protect the environment!
