Overview of environmental pollution

Due to people's insufficient expectation of the negative impact of highly developed industries and unfavorable prevention, three global crises have resulted: resource shortage, environmental pollution and ecological destruction. Humans constantly discharge pollutants into the environment. However, due to the diffusion, dilution, redox and biodegradation of atmosphere, water and soil, etc. The concentration and toxicity of pollutants will naturally decrease, which is called environmental self-purification. If the discharged substances exceed the self-purification capacity of the environment, the environmental quality will change adversely, endangering human health and survival, thus leading to environmental pollution.

There are many classifications of environmental pollution:

According to environmental factors: air pollution, water pollution and soil pollution.

According to human activities: industrial environmental pollution, urban environmental pollution, agricultural environmental pollution.

According to the nature and sources of environmental pollution: chemical pollution, biological pollution, physical contamination (noise pollution, radioactivity, electromagnetic wave) solid waste pollution, energy pollution.

environmental pollution

Environmental pollution will cause direct damage and influence to the ecosystem, such as desertification and forest destruction, and will also cause indirect harm to the ecosystem and human society. Sometimes this indirect environmental impact is more harmful 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 destruction are all environmental impacts caused by air pollution. This kind of environmental effect from environmental pollution is lagging behind, and it is often difficult to be detected or predicted when pollution occurs. However, once it happens, it means that environmental pollution has developed to a very serious degree. Of course, the most direct and easily felt consequence of environmental pollution is to reduce the environmental quality of human beings and affect their quality of life, physical health and production activities. For example, urban air pollution causes air pollution, and the incidence of people is rising. Water pollution worsens the quality of water environment, and the quality of drinking water sources generally declines, threatening people's health and causing premature birth or malformation of fetus. Serious pollution incidents not only bring health problems, but also cause social problems. With the intensification of pollution and the improvement of people's awareness of environmental protection, disputes and conflicts between people caused by pollution have increased year by year.

At present, environmental pollution problems have appeared in different degrees all over the world, including atmospheric environmental pollution, marine pollution and urban environmental problems. With the globalization of economy and trade, environmental pollution is becoming more and more international. In recent years, the problem of transboundary movement of hazardous wastes is a prominent manifestation in this regard.

Protect the earth, starting with me.

Throughout the ages, Mother Earth has raised countless generations of children and grandchildren with sweet milk. It turned out that she was beautifully decorated by junior students. However, now human beings have tortured her to death for their own interests. There is only one earth for mankind; The earth is facing a serious environmental crisis. "Save the Earth" has become the strongest voice of people all over the world.

I feel heartache for the deterioration of the surrounding environment. I think: if teenagers, as future successors, don't understand the composition of human environment and the seriousness of environmental problems, ignore the laws and regulations on environmental protection, don't enhance their awareness of environmental protection, and don't consciously fulfill their obligations to protect the environment, our lives will be destroyed in their own hands, and God will severely punish us. Therefore, I am determined to start from myself and care for the environment.

How to save every drop of water

"Saving water" is not to limit people's use of water, but to prevent, let alone use water. In fact, saving water is to make people use water reasonably and efficiently. Saving water does not affect our quality of life. Everyone has the obligation to cherish resources and correct others' waste of water resources. The view that "as long as I pay the water fee, I can squander it at will, and wasting water is my own business, and others can't control it" is wrong, and the view that "water is only 70 cents, which is very cheap, and it doesn't matter if it is used too much" is even more harmful. Saving water is the responsibility of every citizen. China's water law points out that water resources are owned by the state, that is, by the whole people. All countries in the world also stipulate that water is public property. Therefore, everyone should have a sense of public water. Power resources are also very precious, which embodies the efforts of many people. Everyone should cherish and save water and oppose water pollution and waste. "Look at the former sages and their families, they became thrifty and were defeated by luxury." Running a school with diligence and thrift is a public morality and a virtue. Students, uncles and aunts, let's take action. Let's cherish resources and strive to build a conservation-oriented society.

How to protect the environment

China is a developing country. In the process of socialist modernization, conflicts often occur between economic development and environmental protection. We must protect the environment while developing the economy. 1. In order to develop the economy, it is essential to protect the environment. The purpose of economic development is to improve people's living standards. The purpose of China's economic development is to meet the people's growing material and cultural needs. China was born in a semi-colonial and semi-feudal agricultural country. The economic foundation is weak, the degree of industrialization is low, and the contradiction between economic development and environmental protection generally exists in the process of economic development. Protecting the environment includes protecting people's living environment and natural environment. In cities, economic development, especially industrial development, has a negative impact on residents' lives. In rural areas, there are problems of destroying the natural environment and ecological environment. The purpose of economic development is to improve people's living standards, but in the process of development, the destruction of the environment has affected people's lives, which goes against the original intention of economic development. Second, economic development must protect the environment, which is the requirement of sustainable development strategy. The environment in which we live, our descendants will live here. Our economic development has damaged the environment, and some of the damage is irreparable, which is a crime against future generations. Now all countries in the world attach great importance to the study of sustainable development strategy and vigorously develop green industries and pollution-free industries. China is a big country with a long history and civilization. In the process of economic development, we should pay more attention to environmental protection and leave a beautiful living space for future generations. Three, the development of economy must protect the environment is the requirement of natural law. In the process of economic development, if the natural environment is seriously damaged, then we will be severely punished by nature. The flood is the inevitable result of destroying the environment. I am afraid that the manpower, material resources and financial resources consumed in fighting floods and disaster relief have exceeded the economic development achievements at the expense of the environment. The laws of nature are merciless, and whoever violates them will be retaliated by them. We must attach great importance to protecting the natural and social environment in the process of economic development. Fourth, the fundamental way to solve the contradiction between economic development and environmental protection is to further develop the economy. Development is the last word. We can't lose the protection of the environment because of developing the economy, let alone shrink back on the issue of developing the economy on the grounds of protecting the environment. The way out is to develop the economy. We should strengthen our awareness of environmental protection and use our brains. Economic development and environmental protection are not necessarily contradictory. On the contrary, economic development should promote environmental protection. Vigorously develop high-tech, pollution-free green industries. With the development of economy, the prosperity of the country and the improvement of productivity, people's ability to conquer and transform nature will be further strengthened. People not only have the ability to protect the environment, but also can transform it. Turned the desert into a process. Developing economy is the way to protect the environment. The whole society should pay attention to economic development and environmental protection. At present, many localities and departments develop their economies at the expense of the environment. There are historical and practical reasons for this, but if we look at the problem from a development perspective, people will more deeply realize the importance of environmental protection in the process of economic development. Leaders at all levels should establish environmental awareness, understand economic development and environmental protection from a strategic perspective, base themselves on the overall situation, make overall plans, vigorously develop the economy and improve people's living standards while protecting the environment. In short, there is no contradiction between protecting the environment and developing the economy. In the process of developing economy, we must pay attention to protecting the environment. Because pollution is bound to do harm. The earth is a round world. In fact, there is no absolute waste on earth. Everything can be recycled. However, human intervention has led to the deviation of this cycle and the irrecoverable things. For example, foam lunch boxes in the early years. If so, it is a vicious circle. In this way, the resources of the earth will be consumed. Then the earth will be in danger. Protective measures should be as close as possible to the earth's self-circulation. Prevention should be to do more "farsightedness" and not always focus on economic goals. From the perspective of humanity and nature.
