Environmental protection is the conscious protection of natural resources by human beings and their rational use to prevent the natural environment from being polluted and damaged; It is necessary to do a good job in comprehensive management of the polluted and damaged environment in order to create an environment suitable for human life and work. Environmental protection refers to the general term of various actions taken by human beings to solve actual or potential environmental problems, coordinate the relationship between human beings and the environment, and ensure the sustainable development of the economy and society. Its methods and means include engineering technology, administrative management, law, economy, propaganda and education, and so on.

Its contents are mainly as follows:

1) Prevention and control of environmental pollution caused by production and living activities, including the prevention and control of the "three wastes" (wastewater, waste gas, waste residue), dust, radioactive materials and noise, vibration, foul odor and electromagnetic microwave radiation discharged from industrial production, harmful gases, liquids and noise generated by transportation activities, pollutants discharged from maritime ship transportation, toxic and harmful chemicals used in industrial and agricultural production and people's daily life, and pollution caused by smoke, sewage and garbage discharged from urban life;

2) Prevent environmental damage caused by construction and development activities, including the pollution and damage to the environment caused by the construction of large-scale water conservancy projects, railways, highways, large ports and wharves, airports and large-scale industrial projects, the damage and impact on the environment caused by agricultural reclamation and lake reclamation activities, the development of offshore oil fields, coastal zones and marshlands, the development of forests and mineral resources, and the setting and construction of new industrial zones and new towns;

3) Protect the natural environment with special value, including providing effective protection for rare species and their living environments, special natural development history relics, geological phenomena, landforms, etc. In addition, urban and rural planning, controlling soil erosion and desertification, afforestation, controlling the growth and distribution of population, and rationally allocating productive forces are also part of environmental protection. Environmental protection has become one of the common actions and main tasks of the world's leading countries and peoples today.

China, on the other hand, has declared environmental protection as a basic national policy of China, and has formulated and promulgated a series of laws and regulations on environmental protection to ensure the implementation of this basic national policy.

Top 10 environmental scourges on the planet.

The soil is destroyed. Currently, arable land in 110 countries is decreasing in fertility. In Africa, Asia and Latin America, soil erosion is severe due to the loss of forest vegetation, overexploitation of arable land and overgrazing of pastures.

Air pollution. The problem of air pollution is also the problem of acid rain. Previously, the problem of acid rain had only concerned the older industrialized countries of Europe and North America.

But now, parts of Asia and Latin America, where the economy is booming, are also being hit by acid rain. Air pollution also disrupts the functioning of ecosystems, accelerates the damage to homes, and leads to climate variability.

Fresh water is threatened. In developing countries, 80 per cent of 90 per cent of diseases and more than 1 3 deaths are caused by bacterial infections or chemically contaminated water. Today, 10,000 men, women and children die every day from water-borne diseases.

Climate change and energy waste, the greenhouse effect, seriously threatens humanity as a whole. According to a representative group of 2,500 experts, sea levels are expected to rise. Rising temperatures will also have serious impacts on agriculture and ecosystems.

Reduced forest area. Over the past few hundred years, temperate countries have lost most of their forests. In recent decades, the decline in forest area in tropical countries has also been severe.

At the current rate of forest loss, in 40 years' time, forests will be inaccessible in some Southeast Asian countries.

Reduction in biological variety. Due to urbanization, agricultural development, deforestation and environmental pollution, the natural areas where organisms exist are becoming smaller and smaller, which has led to the extinction of thousands of species.

Millions of chemical compounds from the chemical pollution industry are found in the air, soil, water, plants, animals, and the human body. Even the ice caps, which are the last large natural ecosystems on Earth, are polluted.

The urbanization of the population and the deterioration of agricultural land and poverty have prompted millions of peasants in the Third World to leave the countryside and live in the slums of large cities.

Living conditions in large cities will deteriorate further.

In October 1972, the 27th session of the United Nations General Assembly adopted the recommendation of the United Nations Conference on the Human Environment, designating June 5 as "World Environment Day" every year, so that people around the world can always commemorate it. On this day of the year, the United Nations system and States** should carry out activities to remind the world of the state of the global environment and the dangers of human activities to the environment, and to emphasize the importance of protecting and improving the human environment.

There is only one Earth.

Human habitation. Water, the vital source of life.

Attention is paid to the development of ozone layer depletion, soil erosion, soil degradation and deforestation.

A new decade, a new challenge – development without destruction.

Protecting groundwater and the human food chain, preventing and controlling pollution from toxic chemicalsCommemorating the 10th anniversary of the Stockholm Conference on the Human Environment – raising environmental awareness, managing and disposing of hazardous waste, preventing acid rain damage and improving energy efficiency, and vigilant against global warming.

In 2005, an "environmental storm" swept through Chinese mainland, and 30 projects under construction with a total investment of more than 117.9 billion yuan were halted by the State Environmental Protection Administration. The reason is that these projects have not been assessed and are illegal projects that have not been approved and built without approval, and there is no way out of environmental degradation in China. As early as the 90s of the last century, the problem of environmental pollution was very serious.

Such as the Huai River Basin. In the 90s of the last century, the five categories of water quality accounted for 80, and the entire Huai River was like a huge sewage ditch all year round. In 1995, the economic losses caused by environmental pollution reached 187.5 billion yuan.

According to the Chinese Academy of Sciences, the losses caused by environmental pollution and ecological damage have accounted for 15% of the total GDP, which means that there is an economic growth rate of 9 on the one hand, and a loss rate of 15 on the other. Environmental problems are no longer just a problem for China's sustainable development, but have become a demon that eats away at economic gains.

Second, the state of the environment in our country.

1. Air pollution is soot-type pollution, with dust and acid rain being the most harmful, and the degree of pollution is intensifying.

2. Acid rain is mainly distributed in the south of the Yangtze River, the east of the Qinghai-Tibet Plateau and the Sichuan Basin. Acid rain is the most polluted region in central China.

3. The waters of rivers, lakes and reservoirs are generally polluted to varying degrees, except for some inland rivers and large reservoirs, the pollution has become an aggravating trend, and the water pollution near industrially developed cities and towns is particularly prominent.

4. Among the seven major river systems (Pearl River, Yangtze River, Yellow River, Huai River, Hailuan River, Liao River, and Songhua River), the Yellow River Basin, Songhua River, and Liaohe River Basin are seriously polluted.

5. Total phosphorus and total nitrogen pollution in large freshwater lakes are widespread, and eutrophication is serious.

6. The Bohai Sea and the East China Sea are heavily polluted in the four major sea areas, while the South China Sea is lighter.

7. The deterioration of the ecological environment of fishery waters has not fundamentally changed, and is showing an aggravating trend.

8. Urban environmental pollution is aggravating.

9. Urban ground water pollution is generally serious and shows a deteriorating trend. The vast majority of rivers are polluted to varying degrees.

10. 2 3 rivers and more than 10 million hectares of farmland across the country are polluted.
