First, the government guides the whole society to establish the concept of saving resources.
China is a country short of resources, with per capita water resources less than 1/4 of the world average, arable land less than 1/2 and forests less than 1/7. For a long time, the shortage of resources will be a major event that cannot be ignored in China's economic and social development. To this end, the state regards resource conservation as a basic national policy. In the summer of 2007, the General Office of the State Council issued a notice requiring "all units in public buildings, including state organs, social organizations, enterprises, institutions and individual industrial and commercial households", except for some special circumstances, "the indoor air conditioning temperature should not be lower than 26 degrees Celsius in summer and not higher than 20 degrees Celsius in winter". Through the details of air conditioning temperature limit, I hope to attract the attention and imitation of governments at all levels, and then amplify the coordinated action of the whole people to save resources, so that building a resource-saving society is deeply rooted in the hearts of the people and has become a common practice. Governments at all levels should set an example in saving resources. The national policy of saving resources is formulated by the government, and the implementation of this national policy also requires the government to do a lot of work. Example is more important than language. Government agencies pay attention to saving in every specific matter, which is conducive to guiding the whole society to establish the concept of saving resources and cultivating the social fashion of saving resources for the whole people.
Second, reduce automobile exhaust emissions.
The new theme of World Environment Day in 2007: the worrying consequences of glacier melting. Global warming is an important factor causing glacier melting, and all countries in the world have the same obligation to reduce greenhouse gas emissions, fundamentally reverse the global warming trend and protect human homes. Among greenhouse gases, automobile exhaust emissions are the most harmful. 1943, residents of Los Angeles, USA, found a white mist in the air, sometimes yellowish brown, which stimulated people's eyes to cry. This fog became more and more serious, but it was not until 10 years later that the real culprit-the car was found. The rapid increase of automobile exhaust makes automobile exhaust become the main source of air pollution. One of the solutions is to take fewer cars and advocate taking buses, walking and cycling.
Third, pay attention to the recycling and disposal of garbage.
According to figures released by relevant departments, the total amount of garbage in China is about 500 million tons each year, valued at 25 billion yuan, of which 32% is biological garbage, 18% is plastic garbage, 8% is paper garbage, 4% is textiles, 3% is metals, and 1.5% is glass products, and more than two thirds of these garbage can be recycled. One ton of waste paper can make 800 kilograms of paper; One ton of waste plastic can extract 700 kilograms of gasoline; Recycling cans and glass bottles can save more than 90% of the material cost; Disposable wooden chopsticks can be used to make paper; Biological waste can be made into high-quality fertilizer; Irrecoverable scraps of paper and cloth ends can still be burned to generate electricity. Therefore, garbage is both harmful and valuable. Garbage is a misplaced resource and a raw material mine that will be used one day. It has become an inevitable choice for all countries in the world to carry out classified collection of garbage to achieve the minimum discharge of garbage and the optimal recycling of resources. As the founder of the green campus, I hope that all our classmates will take action, classify and store the garbage, and protect the green home that provides us with learning with practical actions. This is our unshirkable responsibility and our duty.
Fourth, reduce plastic pollution and advocate green shopping.
When we go shopping in shops or farmers' markets, almost everything comes with plastic bags. When we get home, these plastic bags are often thrown into the dustbin immediately. As garbage, plastic bags have left our home, but they have not disappeared in this world. In most parts of China, plastic bags can be seen flying in the air and falling on branches and rivers, which affects health and city appearance. Plastic bags increase the amount of garbage, occupy cultivated land and pollute soil and groundwater. What's more, plastics can't be degraded in nature for hundreds of years, and if burned, it will produce toxic gases. If we use more environmentally friendly shopping baskets and cloth bags to buy food, we can not only reduce the environmental pollution caused by plastic products, but also save resources. German young people are proud of shopping with bags. Let's follow this "green fashion".
Fifth: save resources and protect the environment, starting from me.
Protecting the environment concerns us all. We can do many things, such as: we must abide by the regulations prohibiting littering, and throw rubbish into designated places or containers, especially don't litter waste batteries, because heavy metals contained in a waste battery will cause very serious pollution if it flows into clean water. Save water, please turn off the tap when brushing your teeth. In learning, we should try our best to save stationery and put an end to waste. For example, pencils are made of wood, and wasting pencils is equivalent to destroying forests. We should try to avoid using disposable beverage cups, foam lunch boxes, plastic bags and disposable chopsticks, and replace them with ceramic cups, paper lunch boxes, cloth bags and ordinary bamboo chopsticks, which can greatly reduce the generation of garbage.
Students, we are the little masters of the earth, and it is our bounden duty to save resources and protect the environment. We should start from now, from around us, and from small things. Through our efforts, the sky of the motherland is bluer, the land is greener and the water is clearer. Whether in the past, present or future, whether in the family, the country or the world, the environment will always be our friend. To be kind to friends is to be kind to yourself. Over the years. Our country has been seriously polluted by the environment. Repeated sandstorms in China will bury grasslands, destroy homes, seriously affect people's lives and make it difficult for us to survive. Green grass will become a desert, trees will lie on the ground forever, and we will not live happily: happiness will be gone, and even the earth on which we live will be shattered in the vast universe, just like glass falling to the ground. However, this is not just a disaster caused by sandstorms.
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. A drop of water from the tap every second loses 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!
