It has always been believed that the earth's land, sea and air are infinite, so there is no need to worry about dumping100000 tons of waste gas into the ocean sky and wasting hundreds of millions of tons of garbage. We all think the world is so big. What kind of waste is this? Actually, we were wrong. The earth is very big, but only the creatures living on the seabed from 8 km to 1 1 km above sea level, accounting for 95% of the creatures can only live about 3 km in the middle, and the pollution of the limited living environment is carried out in a three-pronged manner.
Marine pollution: mainly crude oil leaked from oil tankers and oil wells, agricultural pesticides and fertilizers, sewage discharged from factories and acidic solutions from mines; Most of their marine lakes have been polluted. As a result, not only the victims of marine life, but also birds and humans have been poisoned by these creatures.
Land-based pollution: garbage cleaning has become a major city with 1 10,000 tons of garbage every day. Even better, it is not burning or rotting, such as plastics, rubber, glass, aluminum and other wastes. They became the number one enemy of the first city health.
Air pollution: this is the most direct and serious, mainly from carbon monoxide and hydrogen sulfide emitted by factories, automobiles and power plants. Every day, people are infected with the respiratory tract and come into contact with these polluted air or visual organs. If we still ignore the warnings of experts, we will be reduced to the point where we can live without half an inch of pure land in the future.
Environmental pollution refers to the phenomenon that people directly or indirectly discharge substances or energy that exceed their self-purification ability into the environment, which reduces the environmental quality and adversely affects human survival and development, ecosystems and property. Include water pollution, air pollution, noise pollution and radioactive pollution. Water pollution refers to the change of chemical, physical, biological or radioactive pollution characteristics due to the intervention of certain substances, which affects the effective use of water, harms human health or destroys the ecological environment, resulting in the deterioration of water quality. Concentration of air pollution, harm degree of air pollutants, harm to ecosystem and normal survival and development of human beings, harm and biological phenomena. The phenomenon that the environmental noise produced by noise pollution exceeds the national environmental noise emission standard and interferes with the normal work, study and life of others. Radioactive pollution refers to radioactive substances or rays that exceed the national standards on the surface or inside of materials, manpower, workplaces and environmental media caused by human activities. For example, many countries and local governments have formulated pollutant discharge standards and failed to take measures to prevent spilled and leaked loads from transporting oil or toxic goods and goods from falling into the water, causing water pollution, and illegally discharging toxic and harmful substances into the atmosphere, causing air pollution accidents, and so on.
With the development of science and technology and the improvement of people's living standards, there is more and more pollution to the environment, especially in developing countries. Environmental pollution has increasingly become one of the world topics.
Not enough, because people expect that highly developed industries and the prevention of adverse negative effects have led to three major global crises: resource shortage, environmental pollution and ecological destruction. Humans constantly discharge pollutants into the environment. However, due to the diffusion, dilution, redox and biodegradation of air, water and soil. The concentration and toxicity of pollutants will naturally decrease, which is called environmental self-purification. Material discharge exceeds the self-purification ability of the environment, and the environmental quality changes adversely, endangering human health and survival and polluting the environment.
Pollution to the environment will reduce biological productivity and aggravate environmental damage.
The main sources are as follows:
1) Waste smoke, waste gas, waste water, waste residue and noise discharged by the factory;
2) Environmental pollution, waste gas, noise, sewage and garbage caused by waste gas discharged in people's lives;
3) Exhaust gas and noise generated by vehicles (all fuel-fired vehicles, ships, airplanes, etc.). );
4) A large amount of water produced by chemical substances such as fertilizers, pesticides and herbicides is used for farmland irrigation.
) Mine wastewater and waste residue.
The harm of water pollution is self-evident. Water pollution and water quality deterioration have brought serious environmental protection problems to human health, human life and production, which is the biggest problem faced by human beings in modern life. To solve this problem, we must start from the foundation.
First of all, a lot of publicity has been carried out to improve people's awareness and understanding and their awareness of environmental protection.
Secondly, waste recycling can reduce the felling of forest trees. We should also strengthen the control of white pollution and use less plastic products.
Finally, in order to improve cleanliness. A cleaner city.
For the future of the earth, we must work hard to protect the environment from now on. In this regard, we make the following suggestions:
Sorting and bagging garbage not only reduces the workload of sanitation workers, but also has better effect, because waste utilization reduces pollution and saves resources. such as
Buy food, reduce the use of plastic bags and try to use bamboo baskets.
Try to use interchangeable refills for pens to reduce the waste and waste of ballpoint pen shells.
Try not to use disposable lunch boxes when eating.
Planting green technology, sowing hope for excessive garbage and waste recycling, environmental problems and comprehensive utilization of resources, waste recycling and resource utilization (Part II) bathroom
Bottled drinking pure water reminder
Nowadays, drinking water is becoming a trend. Despite the shortcomings of the media more than once, the drinking water tribe is still growing.
Drinking water not only refers to pure water, mineral water, distilled water and space water, but even we grow up drinking tap water and become non-drinking water. We not only play a certain role in excluding drinking water speculation, but also reflect that the water body is seriously polluted and inedible.
Second:
Bright and clean classroom, sitting by the water, walking by the clear lake and driving, the shade is like grass on the football field, I will feel happy.
But there is a long-term crisis lurking around us, and maybe one day this beautiful scenery will leave us. All this is caused by human beings themselves. The key to the gate of heaven and hell, the key to the door held by human beings. Students should consciously fulfill their responsibility to protect the environment, improve their awareness of environmental protection, enhance their legal awareness and their ability to implement environmental protection actions. Be a "little guardian of civilization".
Our earth is a beautiful planet, but soil erosion and desertification still plague human land and maintain people's crazy occupation. According to statistics, deserts and wasteland on the earth expand and extend fields at the rate of 270,000 hectares of desertified land in China every year? Every year 1560 km2. At present, the area of desertified land and potential desertified land in China is nearly 6.5438+0.5 million square kilometers. Park1280,000 square kilometers. Desertification has become the most serious global environmental problem.
I have seen this comedy. After patrolling two cars on the screen, people beat gongs and drums. In front of a car, a red letter reads: Good news, the output value of the chemical plant is more than 3 million yuan. Passing cars frowned, and a note read: I am worried that 300,000 Jin of grain production will seriously endanger nearby residents due to chemical pollution, and several surrounding rivers cannot be used. The court ordered rectification within a time limit and imposed a fine. High is worrying and obvious. These are all warnings from nature, reminding us not to forget the severe punishment and painful lessons of nature. This will promote the future and we must protect the environment.
Environmental pollution will do harm to our bodies and spirits. In order to protect our health, we need to improve and strengthen the social awareness of environmental protection. The earth is our mother, and we should have a lot of sewage veins, and a lot of garbage is buried in its meat. The earth is not a dump. We can't spit, litter, scraps of paper, cigarette butts and other sundries in public places. Note that black spots are covered with green glue and throwing plastic bags will cause "white pollution", but it will also turn this place into a barren, dirty and muddy world everywhere. These actions completely violate socialist spiritual civilization and social morality.
The knife cuts bread and fingers. Solution manufacturers, if humans can protect trees in time, save water and reduce environmental pollution caused by wastewater discharge. We high school students should take an active part in voluntary labor. Let's work together to protect the living environment, make the campus clean first, and make contributions to the cleanliness of the city. Friend, a love problem and effort! We must start from ourselves, from the small things around us, and protect the environment we depend on through our own actions. The mistake of destroying the ecological environment cannot be made.
We are citizens of the motherland and masters of the 2 1 century, so our own country and a responsible society are our home. The quality of social members directly reflects the culture of the whole society. China's country has a history of 5,000 years of civilization, and as a gift, it is our traditional virtue in China, such as the country and every member of society. "Virtue produces good habits, and good moral quality fosters civilization. Only a small number of "thoughtful people" are civilized, orderly and have good living habits. When they grow up, they may act consciously.
"It's not too late to mend." We hope that all people have sounded the alarm, as we said, we only have one earth! We must protect our home. From now on, we should take urgent action to control pollution, green the environment and prevent the recurrence of pollution tragedy. Be a "little guardian of civilization".
Article 3:
I love the earth and the home where we live. Love her mountains, love her green grass and blue sky. ......
In the field investigation, fragrant flowers and butterflies play, laugh and laugh, dense forests, birds chase and sing with me. In the early morning, I walked lightly into the field and walked like a mist covered with white gauze. Suck the flowers, welcome to enjoy the sunshine bath, I am intoxicated in the intoxicated dream; In the evening, I sat in the fragrant rice in the farm yard, watching the bright stars and listening to the cicadas and frogs, feeling as if I were in a fairy tale kingdom. In spring, I sit in the back row of the bull market, listening to the endless grassland pastoral. In summer, I sat in a boat and let the oars beat the green lake to watch the seagulls cross the vast lake; In autumn, I stand under the tree and look forward to it with my heart. In autumn and winter, I stood at the window and watched the snowflakes flying in the air. My heart is drunk in this picturesque paradise on earth!
For a period of time, people who cut down trees indiscriminately were destroyed, so the ecological balance of nature. Dunes have swallowed up thousands of hectares of fertile land, lovely homes have been washed away by floods, and nature's revenge has stunned people. Wei said, unnatural, this is not human, this is a simple truth, blindly plundering and conquering nature will only destroy the ecological environment, and we can only blame ourselves. Mankind is on the verge of difficulties. This does have some advantages, and people will not lose face. Naturally, of course they won't fall behind. The flood in 2000 and the sandstorm in 1998 are actually human nature.
Once upon a time, friends who killed people were arbitrarily arrested and trampled. "Qian Shan birds fly, killing the consequences of thousands of miles without leaving footprints, this is the most true portrayal. From college students to bear events, crazy hunters who cheat them should also be under their own guns? Please remember that protecting animals means protecting ourselves.
Once upon a time, the outbreak of war destroyed the survival of this planet. Firefighting vegetation and nuclear radiation damage life, although Hiroshima mushroom cloud disappeared in Nagasaki for more than half a century, it is still barren. Therefore, green peace is an important prerequisite for mankind.
I can't imagine what kind of tragedy the world will be if this continues. The ground is barren, the sky is dusty, human demons scream, and piles of bones. Then we can only say that man once belonged to the earth, but the earth will never belong to man again.
Gu once said that every man is responsible for the rise and fall of the world. The historical task of protecting the environment and maintaining ecological balance will fall on the shoulders of a generation in the next century. Let's care for nature, the earth, hand in hand, shoulder to shoulder, heart to heart, jump from a green river bank, defend resources, protect the environment, protect the earth and protect our beautiful home!
