<>We all know that severe air pollution can cause respiratory diseases at least and plant the root cause in the body. The causes of air pollution are all aspects, and we have also taken relevant rescue measures many times, such as strictly resisting some polluting enterprises, paying attention to the conversion of emission gases, and ensuring that the air is pollution-free as much as possible.
And one of the most useful countermeasures today is "green travel". With the improvement of our country's economic level, people's living standards are getting better and better, and cars have become a necessary means of travel for almost every household. The construction of wider and wider roads symbolizes the speed of economic development in our city, but at the same time, the appearance of more and more vehicles also has a profound impact on our living environment.
Vehicle exhaust emissions are also one of the important factors causing air pollution.
Nowadays, everyone is accustomed to driving when they go out, no matter what they do, no matter how far or near the road they are used to driving, and the vehicle is not only our means of transportation, but also our "legs". According to the calculation of two trips per household a day, there are so many families in the world, and the daily car exhaust emissions will be a rather terrible number, that is, these exhaust gases continue to pollute our living environment, and the air quality is getting worse and worse, and over time it is harmful to ourselves. Therefore, we must always pay attention to "green travel" and reduce environmental pollution.
Green represents hope and rebirth, in the face of environmental problems, we must give the greatest hope, and make the greatest efforts to make the environment "reborn", and give all of us a green and quiet place to live. Green travel is actually very simple, we must always pay attention to establish the concept of green travel, especially for children, to tell them the meaning of green travel from an early age. We can also set an example for them by taking public transportation such as buses, subways, and now the popular bike-sharing.
Of course, when we choose vehicles and fuels, we should choose new energy vehicles as much as possible, and choose models with high energy-saving and emission reduction performance. Sometimes some short routes, we can reach them by walking, cycling, etc., to reduce the use of cars as much as possible.
Students, green travel is not a matter for any of us alone, we need to work together, and every family can pay together to return the earth to a green place! Protecting the environment and going green, starting from now, we must work hard to persevere!
O human! You are growing so fast, and you are greedily sucking the Earth's resources. However, this is a point of no return!
Admittedly, no one wants to give up the reinforced concrete building and move back to the thatched house; No one wants to give up the electric light and light a kerosene lamp for a long night; No one wants to give up a car and ride on their feet or a donkey, and not only that, but the vast majority of people want to have better and more technological products after they have basic satisfaction. And all this material enjoyment comes at the cost of the environment.

<> now that the earth's environment is getting worse and worse, many people still don't take him seriously. Garbage is flying all over the sky, floating on the branches, in the river, everywhere, polluting the river, the small fish and shrimp that used to play in the river have disappeared without a trace, and the birds that used to sing on the branches are gone. People cut down a lot of trees, and China currently produces and discards 45 billion pairs of disposable chopsticks every year, which is equivalent to 25 million adult trees being cut down!
Many plastic products have to be buried in the ground for thousands of years before they can be decomposed, and greenhouse gases are constantly being released during this time! Seeing this, will you still be indifferent?
We should start from small things, do not litter, do not spit, drive less private cars, go out to take a car, it is best to do a bus, a variety of flowers and trees, go out to carry chopsticks and bags, avoid using disposable chopsticks and plastic bags, etc.
At one point, I didn't go green. That night, I wanted to throw away the used homework, but my mother saw it and said to me: "These papers can still be reused, what a pity to waste them, the back of the paper can still be used, you can use it to make straw paper."
I lowered my head and realized my mistake, and from now on, I was not wasting anything.
The earth is our great mother, although she is forty-five billion years old, but the earth's'Youth and aging are not measured by age, as children of the earth, we should let our mothers be young forever! Come on, let's work together, I believe that if everyone makes an effort, small forces will come together into great power, so that our mother earth will surely regain its former health and beauty!

1. Environmental protection slogans.
1) Conservation of biodiversity.
2) Cherish life, protect the environment, and benefit mankind.
3) Soil consolidation and sand control, grass and trees are the master.
4) Trash is a misplaced resource.
5) Bit by bit environmental protection, earnestly strong national heart.
6) Be kind to nature and balance the ecology for all generations.
2. The content of the hand-copied newspaper for environmental protection: fairy tales about environmental protection.
A little rabbit jumped up and down to play in the park. There are many animals in the park, including bulls, hippos, baby squirrels, elephants, zebras, ......It looks like it's been turned into a zoo. Some of the animals are walking in the cave, some are exercising, and some are ...... activities
The little rabbit walked over to a chair and sat down. Then, he took out the packet of cookies he had brought with him and ate them with relish. The little rabbit was very hungry, and at once he finished the bag of biscuits, threw the bag in his hand, and threw it on the grass and walked away.
After a while, the little rabbit saw a sign on another meadow that said, "Everyone has a responsibility to protect the environment." The little rabbit read these eight words and understood: you can't litter, and the littering environment will be damaged.
So, the little rabbit hurriedly ran back to the place where he had just thrown the bag, picked it up, and threw it into the trash.

Give me: We should learn about environmental protection, search for some knowledge about environmental protection on the Internet, we should give more water, we should take care of every green leaf, every grass, and every flower. Love the earth, protect the environment, green campus, let green life inspire us to love life, let us work together, let the seeds bloom, let the seedlings become green, with practical actions into the March "tree planting, love green, green protection" activities, from their own side, to prove to the whole society that we are a high-quality generation, we really know how to cherish the green and love the green, we all know that due to the excessive demand of human beings to the natural world, has led to the ruthless revenge of nature:
Hurricanes, torrential rains, blizzards, floods, droughts, insect pests, extreme heat, forest fires, ** and other disasters are unexpected, and the number of displaced refugees due to drought and other reasons in the world is expected to reach 100 million by 2025. Man grows in nature, and green is the color of nature. How precious green is!
It is life, hope, and happiness, let us take action to cherish and care for the green to create green. Many human activities discharge harmful substances into the atmosphere, water, soil and other natural and artificial environments, causing environmental pollution; Some changes in nature also affect the quality of the environment. Environmental monitoring is to carry out qualitative and quantitative tests on the discharge of pollution sources and environmental conditions in accordance with various national or local environmental standards for pollution prevention and protection of environmental quality, and provide a basis for scientific research, decision-making, legislation, handling of pollution accidents and environmental supervision and management.
Environmental monitoring is the "eyes and ears" of all environmental protection activities. In practice, environmental monitoring can be divided into two categories. The first is pollution source monitoring, that is, the monitoring of pollutant discharge.
Generally, samples are collected regularly and at fixed points at the pollutant discharge outlet, and the concentration, emission and temporal and spatial distribution of different forms of harmful substances are analyzed and determined. The second is environmental monitoring, that is, the analysis and monitoring of pollutant substances in the environment and their change laws and environmental impacts, clarifying their values, scope, and pollution degrees, and describing the environmental quality status and development trend through comprehensive analysis.

There are various classifications of environmental pollution:
According to environmental elements: air pollution, water pollution, soil pollution.
According to human activities, it is divided into industrial environmental pollution, urban environmental pollution, and agricultural environmental pollution.
Environmental pollution will cause direct damage and impact on the ecosystem, such as desertification, deforestation, and indirect harm to the ecosystem and human society, and sometimes the harm of this indirect environmental effect is greater than the direct harm caused at that time, and it is more difficult to eliminate. For example, the greenhouse effect, acid rain, and ozone layer depletion are environmental effects derived from air pollution. This kind of environmental effect derived from environmental pollution has a lag, and is often not easy to detect or predict at the time of pollution, but once it occurs, it means that environmental pollution has developed to a very serious point.
Of course, the most direct and easily felt consequence of environmental pollution is to reduce the quality of the human environment and affect the quality of human life, physical health and production activities. For example, air pollution in cities causes air pollution, and people's morbidity increases. Water pollution deteriorates the quality of the water environment, and the quality of drinking water sources generally declines, threatening people's health, causing premature birth or malformation of the fetus. Serious pollution incidents not only cause health problems, but also social problems.
With the intensification of pollution and the improvement of people's environmental awareness, the number of disputes and conflicts among people caused by pollution is increasing year by year.
At present, environmental pollution problems have occurred to varying degrees in the world, and the aspects with global impact include atmospheric environmental pollution, marine pollution, and urban environmental problems. With the globalization of the economy and the world, environmental pollution is also increasingly internationalized, and the transboundary transfer of hazardous wastes in recent years is a prominent manifestation in this regard.

Overview of environmental pollution.
Due to the lack of anticipation and prevention of the negative impact of highly developed industry, it has led to three major crises around the world: resource shortage, environmental pollution, and ecological destruction. Human beings are constantly emitting pollutants into the environment.
However, due to the effects of diffusion, dilution, redox, biodegradation, etc. of the atmosphere, water, soil, etc. The concentration and toxicity of pollutants naturally decrease, a phenomenon called environmental self-purification. If the emitted substances exceed the self-purification capacity of the environment, the quality of the environment will undergo adverse changes, endangering human health and survival, which will cause environmental pollution.

A good environment can give birth to a good mood and lead a better life. Tidying up your room is actually the beginning of a better life. Writer Yang Daxia Yang Ke analyzed that creating an atmosphere is to lead oneself.
1.Every flower and grass is life, and every branch and leaf is always about 2Laughing in the flowers and plants, enjoying its appearance outside the garden 3Take three or five steps around to leave the grass green. 4.When trees are green, the earth has its pulse5The red flowers and green grass are planted all over the garden, and the wind sends flowers and fragrant dishes when they come.
Caring for the environment, there is no price, but it makes people's hearts noble; Care for the environment, there is no volume, but it makes people broad-minded; Caring for the environment, there is no weight, but it makes people lift weights like light.
