On the current environmental problems of our country 40

Nothing can be used with confidence!!

Environmental issues. The main categories are as follows:

1. According to environmental elements: air pollution, water pollution, soil pollution;

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

Radioactivity, electromagnetic waves.

Solid waste pollution, energy pollution.

The main causes of environmental problems:

First, the one-sided pursuit of economic value and the neglect of ecological value cause environmental problems. Pollution caused by industrial wastewater, waste gas, and waste residue generated by industrial development;

Second, the rapid decline of vegetation causes environmental problems. In order to ensure rapid economic growth, excessive reclamation at the expense of the environment has led to extremely serious land degradation.

Third, environmental problems caused by urban development. A series of environmental problems due to urban development have brought many inconveniences to people's life and production.

The fundamental way to solve environmental problems:

Population surge, economic development, and scientific and technological progress are the root causes of environmental problems, and the solution to environmental problems must rely on controlling the population, strengthening education, improving the quality of the population, enhancing environmental awareness, strengthening environmental management, and relying on strong economic strength and scientific and technological progress. First of all, population control has a special and important role in solving contemporary environmental problems, and at the same time, it is necessary to strengthen education to raise their environmental awareness and solve environmental problems through various technical means, especially environmental management. To solve environmental problems, we must have considerable economic strength, require huge financial and material resources and long-term efforts, and must also use scientific and technological progress to solve environmental problems.

Solution: First, change the production mode and vigorously develop the circular economy.

Transform the traditional production model "resource-product-waste" into a circular economy production model "resource-product-renewable resource". Traditional.

The faster the economic development of the production model, the greater the environmental cost to pay, not only wastes resources, but also the waste produced occupies arable land, affects soil quality, and reduces the output of agricultural products. The circular economy overcomes this shortcoming. Transform waste into "renewable resources", improve production and ecological efficiency, obtain maximum economic output and produce minimum environmental pollution with the least consumption of resources, and establish a sustainable production and consumption model.

Second, it is necessary to improve the level of allocation of scientific and technological resources and the efficiency of operation. Through the development of new science and technology, improve the efficiency of resource use, and establish a conservation-oriented social and economic system. That is, China's industrialization is required to achieve a "low input, high output, less pollution", a circular development mechanism.

Through the development of science and technology as the support, the establishment of a harmonious science and technology system between people and the environment.

Third, on the basis of conservation, the natural environment should be restored.

Although the development of a conservation-oriented economy can reduce the impact on the environment to a certain extent, in order to essentially improve the environmental problems, they must be repaired on the basis of conservation. In the process of revegetation, emphasis is placed on the use of natural laws.

Make full use of nature's self-healing ability, combined with local artificial measures, to achieve the purpose of restoring the environment. These include the restoration of forests, wetlands, and farmland ecosystems. Forests and wetlands play an important role in alleviating floods, preventing droughts, and conserving water sources.

1. Air pollution: The situation facing the atmospheric environment around us is very severe, and the total amount of air pollutant emissions remains high.

2. Water pollution: China is a country with serious drought and water shortage, and people are still wasting water resources while making scientific progress.

3. Garbage disposal: China's annual production of industrial solid waste reaches 100 million tons, and the comprehensive utilization rate is about 46%. China's annual production of municipal solid waste is 100 million tons, which meets the requirements for harmless treatment of less than 10%. White contamination from plastic packaging and agricultural film has spread across China.

4. Biological destruction: China is a country with serious damage to biodiversity, with 4,000-5,000 endangered or near-endangered species of higher plants, accounting for about 15%-20% of the total number of species owned by China, higher than the world average of 10%-15%.

Environmental problems in our country.

The main manifestations are: large pollutant emissions, much higher than the self-cleaning power of the environment; Industrial pollution is serious, urban life pollution has increased significantly, and some places that have been treated have recurred; In many areas, agricultural water quality and soil pollution are serious, and harmful residues of agricultural and sideline products exceed the standard, affecting human health and product exports; Soil erosion, increased desertification, biodiversity.

Sharp reduction, reduction of land resources, freshwater resources.

Odd shortage, and so on. At present, the environmental protection situation in China is still severe, and potential environmental problems are still emerging.

1. Air pollution.

China's sulfur dioxide emissions rank first in the world. Air pollution is currently the number one environmental problem in China.

2. Water environment pollution.

The pollution degree of China's seven major water systems is: Liaohe River, Haihe River, Huai River, Yellow River, Songhua River, Pearl River, and Yangtze River, of which 42% of the water quality exceeds the 3 categories of standards (can not be used as a drinking water source), and 36% of the urban river sections in the country are inferior to 5 categories of water quality, which has lost its use function. The water quality of large freshwater lakes (reservoirs) and urban lakes is generally poor, and more than 75% of the lakes have increased eutrophication, mainly caused by nitrogen and phosphorus pollution.

3. Garbage disposal problems.

At present, the comprehensive utilization rate of industrial solid waste in China is about 46%. Less than 10% of the country's municipal solid waste meets the requirements for harmless treatment. White contamination from plastic packaging and agricultural films has spread across the country.

Ways to protect the environment:

1. Save water and close the faucet to prevent dripping.

2. Use detergents with caution and use soap as much as possible. Reduce water contamination by chemicals in detergents.

3. Try to use as few disposable items as possible. Use durable goods, reduce white pollution, and bring your own shopping bag or basket.

4. Do not litter waste batteries, waste plastics and other garbage; Waste sorting and putting waste into treasure and recycling.

5. Do not hunt, use rare animals and protected animals. Afforestation, take care of every inch of flowers and trees.

I think it's supposed to be smog.

Hello, China's current urban environmental pollution situation is serious. (1) Serious air pollution: Although China's air pollution has been effectively controlled in recent years, the problem still exists, especially in winter, haze days will always appear, which has a lot to do with the long-term use of coal in China, and the large consumption of coal has led to serious acid rain pollution in some areas, especially in the southwest and southeast acid rain areas.

2) Deterioration of water environment pollution: nearly half of the country's major rivers and lakes are seriously polluted, nearly 90,010 urban water quality exceeds the standard, almost all the fish in thousands of kilometers of river sections are extinct, about 50% of the small and medium-sized rivers do not meet the fishery water quality standards, and the economic losses caused by the annual pollution and death of fish accidents are as high as 400 million yuan, which seriously threatens the economic interests of the country and the people. (3) Noise and solid waste pollution are still serious

Urban road noise pollution is serious, and many cities are deteriorating, according to relevant data monitoring, most of the urban noise level exceeds the standard.

Air pollution, water pollution, garbage disposal, land desertification and sand disasters, soil erosion, drought and floods, biodiversity destruction, WTO and the environment, environmental problems in the Three Gorges Reservoir area, persistent organic matter pollution, etc.

Governance: To implement environmental protection work, it is necessary to rely on scientific mechanisms. The environmental protection working mechanism is responsible for the environmental quality of the jurisdiction, the environmental protection department implements unified supervision and management of the environmental protection work, and the relevant departments are responsible for the division of labor.

Ecological and environmental problems can generally be divided into three categories:

1) Ecological damage caused by the irrational exploitation and utilization of natural resources. It mainly includes the sharp decline of biological species, soil erosion, land desertification, etc.

2) Environmental pollution. For example, the "three wastes" (wastewater, waste gas, waste residue) pollution, noise pollution, pesticide pollution, etc., caused by urbanization and the high development of industry and agriculture; Global warming, acid rain pollution, ozone layer depletion.

3) Shortage of resources. Water shortage, land resource shortage, etc.
