What are the causes of harsh environments?

There are several reasons for the deterioration of the ecological environment:

1. The irrational development and utilization of resources is the main reason for the deterioration of the ecological environment.

2. The long-term lack of investment in ecological environmental protection and construction is also an important reason for the deterioration of the ecological environment.

3. The awareness of environmental protection is not strong, the emphasis is on development over protection, construction over maintenance, and the predatory and extensive development and utilization of resources is adopted, which exceeds the carrying capacity of the ecological environment.

4. History has long lacked awareness of protecting the ecological environment.

5. Excessive emphasis on engineering measures and neglect of biological measures.

6. Some ecological construction projects ignore the natural environment in the western region.

Peculiarity. 7. In terms of ecological environment construction and management, the policy of "protection first, prevention first, and prevention and treatment combined" has not been seriously implemented.

8. The area is vast, the natural conditions are complex, and the landform type is complex.

Diverse. 9. Weak supervision of departments and units, lax law enforcement, and ineffective management have led to many phenomena of ecological and environmental damage that have been repeatedly prohibited, aggravating the degradation of the ecological environment.

The main reasons for environmental degradation are: 1. The reason for the deterioration of the atmospheric environment is that there are more and more cars now, and automobile exhaust emissions seriously pollute the atmosphere; The air emitted from factories and air conditioners can also lead to the deterioration of the atmospheric environment. 2. The main reason for the deterioration of the water environment is the direct discharge of industrial wastewater and the direct discharge of domestic wastewater.

There are many reasons, among which the destruction of human beings is very large, such as sewage pollution, air pollution, etc., all because of the factory. Of course, there are some natural factors that are irresistible.

In fact, the most important cause of environmental degradation is people, and all activities generated by people may have an impact on the environment, such as our industry, our agriculture, our travel, and our excavation and burning of natural resources.

It's as simple as three:

1. Artificially destroying or changing the original ecological structure foundation for the sake of production and life.

2. The artificial introduction of alien species changes the original ecological chain.

3. Chemical pollution, nuclear pollution and other comprehensive damage to the ecological chain.

The amount of waste discharged into the environment by humans exceeds the self-purification capacity of the environment, resulting in a decline in environmental quality. The amount of waste that people dispose of into the environment is numerous and complex, and some wastes are almost impossible to degrade in the environment.

First, economic growth is still supported by high input, high consumption, high emissions and high pollution. According to reports, compared with developed countries, Guangdong's environment and economic coordinated development gap is very large, and the water consumption per unit of GDP is twice that of the United States, South Korea, and Mexico; The water consumption per 10,000 yuan of industrial added value is 10 times that of foreign advanced level and 4 times of the world average; Energy consumption per unit of GDP is twice that of Japan and ...... times that of the United States

Second, the discharge of sewage and waste gas is still increasing significantly. For example, last year, the province's annual sulfur dioxide emissions reached 10,000 tons, an increase over the previous year, but the installed capacity of completed desulfurization increased by only 5% compared with the previous year; The urban sewage treatment rate in the province is only 35%, the sewage collection pipe network is not perfect, and a large number of untreated domestic sewage and agricultural irrigation water are directly discharged into the rivers; The amount of urban domestic waste generated is growing at a rate of 10%, but most of them are simple landfills, no effective pollution prevention and control measures have been taken, and they cannot meet the standards stipulated by the state, causing secondary pollution to soil and water bodies.

Third, the climate is abnormal, and the self-purification ability of the environment is reduced. Last year, Guangdong experienced the worst drought in 40 years, and the climate was extremely abnormal, reducing the environmental self-purification capacity of urban air and river surface water.

Environmental pollution is caused by the discharge of a large number of harmful substances into the environment produced by human life activities and production activities; Specifically, it includes: air pollution, water pollution, greenhouse effect, noise pollution, solid waste pollution, etc

With the development of industrial production and the improvement of human living standards, the demand for fossil fuels such as coal, oil, and natural gas continues to increase, and they release a large amount of carbon dioxide gas after combustion. This is known as the "greenhouse effect".

Freon is the culprit of ozone layer destruction, Freon is a colorless gas or volatile liquid at room temperature, slightly fragrant, low toxicity, chemically stable Often used as a refrigerant, foaming agent and cleaning agent, widely used in household appliances, foam plastics, daily chemicals, automobiles, fire equipment and other fields

It can be said that there are all walks of life in the deterioration of the environment caused by man-made, medicine, electronics, agriculture, light industry, heavy industry, and life, which are the reasons for our getting worse and worse.

We can also feel the deterioration of the environment around us, with less and less sunny and cloudless weather, dusty roads, constant noises in our ears, rivers and lakes no longer clear in color, invasion of alien species, more and more diseases, and an increase in the deformity rate of children......Wait a minute.

Xie Zhenhua, head of the State Environmental Protection Administration, said that China's ecological environment situation is still grim, mainly due to the extensive economic growth model.

He said: Since the beginning of reform and opening up, China's economy has made great progress, but it has also paid a heavy price. The environmental problems encountered by developed countries in the course of 100 years of industrialization have occurred rapidly in China in just 20 years. Now we have to face the environmental problems caused by excessive consumption in developed countries, and the ecological damage caused by underdevelopment and poverty in developing countries.

Due to the irrational economic structure, the traditional mode of resource development and utilization has not been fundamentally changed, the idea of emphasizing development over protection and construction over management and protection is still widespread, and the phenomenon of sacrificing the ecological environment in exchange for immediate and partial interests is still serious in some areas. Rapid economic growth has put tremendous pressure on the ecological environment.

In addition to the above reasons, the ecological protection system is not smooth, the foundation is weak, and the strength is insufficient.

In addition, the people's awareness of environmental protection is not perfect, and economic interests are always the priority, which has led to many disasters. For example, sandstorms, desertification, water pollution, algae overflow, invasion of alien species, increased floods and droughts, and agricultural and industrial pollution.

For the sake of future generations, I think that at least from the new generation, we should pay attention to environmental protection, and do not wait until it is irretrievable to remember that we should have established a sewage treatment project at that time. The fact that global warming has become apparent, that people's original weather has begun to change significantly, and that our Taihu Lake has just erupted with blue-green algae is really shocking.

Environmental pollution refers to the phenomenon that due to human factors, pollutant substances enter the environment, so that the composition and state of the natural environment have changed, the structure and function have been destroyed, the environmental quality has deteriorated, the ecosystem has been destroyed, and the production and life of human beings have been harmed. Specifically, environmental pollution refers to harmful substances, mainly industrial"Three wastes"Pollution of the atmosphere, water, soil and organisms (exhaust gases, waste water and waste residues). Environmental pollution includes air pollution, water pollution, soil pollution, biological pollution and other pollution caused by substances and pollution caused by physical factors such as noise pollution, thermal pollution, radioactive pollution or electromagnetic radiation pollution.

Some heavy and light industries such as fertilizer factories, as well as food processing, paper industry, coal mining processing, petroleum refining, etc., are more likely to pollute the environment.

The most important cause of environmental degradation is people, and all the activities generated by people may have an impact on the environment, such as our industry, our agriculture, our travel, and our excavation and burning of natural resources, all of which may produce some things that deteriorate the environment, including our air and water pollution, as well as the rapid change of the entire climate, which are related to human activities.

Therefore, we must first be ourselves and not do things that damage the environment.

1. Land pollution: The cleaning of garbage has become an important problem in major cities, and many of the tens of millions of tons of garbage every day cannot be incinerated or corrupted, such as plastic, rubber, glass and other human enemies.

2. Marine pollution: leakage from oil tankers and oil wells, pesticides and fertilizers used in farmland, sewage discharged from factories, acidic solutions flowing from mines; The cause of the poor environment of the earth Answer: Human beings continue to improve their quality of life while causing inevitable damage to the environment, big or small, over time the problem will be big, and nature will begin to retaliate against human beings, we will find that the earth's environment is bad!

There are many reasons for the poor environment, the most important is littering, and there is also the pollution of the environment by some chemical plants.

The excessive predatory use of natural resources and the uncontrolled and uncontrolled discharge of industrial waste are all the driving forces behind the poor environment.

Hello The main reasons for the poor environment are, the pollution of factories, the carbon dioxide caused by the cutting down of trees and the destruction of nature.

1. Dig river sand.

Over-exploitation of groundwater, over-exploitation and beneficiation, artificially destroying geological landforms, resulting in the deterioration of the natural environment.

2. Cutting down trees, destroying forests and wetlands, and causing abnormal climate change.

3. Hunting and killing wild animals.

The imbalance of the natural biological chain has led to the deterioration of the ecological environment.

4. Establish polluting factories that emit a large amount of polluting gases and cause air pollution.

5. Industrial wastewater is not up to standard, polluting water resources.

The phenomena that damage the environment include indiscriminate logging, overgrazing, the establishment of polluting factories, the emission of large quantities of polluting gases, the arbitrary killing of wild animals, the continuous development of new elements, the production of a large amount of pollution, the development of a large number of cultivated land, the development of a large number of tourist areas, the destruction of the natural environment, the cutting down of forest land, and the construction of a large number of high-rise buildings.

The white light pollution in big cities is very serious, especially in summer, when the day is empty, the appearance of high-rise buildings is white light, and the cement bricks on the ground reflect high temperatures, which is really unbearable.

Let our human lives be seriously threatened, and the home on which we live will no longer be beautiful. It's scary to think about, and I hope that protecting the environment starts with me.

Global warming, acid rain, sulfur dioxide, maybe continue to pollute, human beings will not be able to survive on the earth, how serious the pollution of a waste battery is, or to protect the environment a little bit of small things around you.

The environment is harsh, causing water pollution, various diseases are complicated, cancer is cold-like, and many Chinese people do not have this awareness on the issue of drinking clean water.

It's really terrifying, the environment is harsh including climate, soil, atmosphere, etc., now the main thing is the climate, climate changes bring us a lot of environmental changes, such as the colder the winter, the hotter the summer, uneven precipitation, drought in some places, some floods, food production reduction, directly affect our lives. The presence of extreme temperatures has also led to an increase in the number of people who have fallen ill. ‍‍

In addition to the direct damage and impact of environmental pollution on the ecosystem, the accumulation, migration and transformation of pollutants will also cause a variety of derived environmental effects, causing 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.

Except. For example, the greenhouse effect, acid rain, and ozone layer depletion are environmental effects derived from air pollution.

Rising disease rates, unclean air and water, soil erosion, desertification, greenhouse effect, abnormal climate, other disasters, deterioration of seawater, extinction.

Specifically, harmful substances or harmful factors enter the environment and diffuse, migrate and transform in the environment, and interact with the elements of the ecological system, so that the structure and function of the ecosystem change, and have an adverse impact on the survival and development of human beings and other organisms. For example, due to the combustion of fossil fuels, the concentration of particulate matter and SO2 in the atmosphere increases, which endangers the health of humans and other organisms, and at the same time, it will corrode materials and cause losses to human society; The discharge of industrial wastewater and domestic sewage deteriorates the quality of water bodies and endangers aquatic life.

The water body loses its original ecological function and use value.

The harsh environment can pollute the water, and through the drinking water or food chain, pollutants can enter the human body, causing acute or chronic poisoning. Arsenic, chromium, ammonium, benzo(a)pyrene, etc., can also induce cancer. Water contaminated with parasites, viruses or other pathogenic bacteria can cause a variety of infectious and parasitic diseases.

Water polluted by heavy metals is harmful to human health. Water and food contaminated by cadmium can cause kidney and bone lesions after human diet, and ingestion of 20 mg of cadmium sulfate will cause death. Poisoning caused by lead, causing anemia and nervous disorders.

Hexavalent chromium is very toxic, causes ulcers, and has carcinogenic effects. Drinking arsenic-containing water can cause acute or chronic poisoning. Arsenic inhibits or inactivates many enzymes, causing metabolic disorders, keratinization, and cancer.

Organophosphorus pesticides can cause neurotoxicity, and organochlorine pesticides will accumulate in fat, causing harm to the endocrine, immune function and reproductive function of humans and animals. Most of the fused aromatic hydrocarbons have carcinogenic effects. Cyanide is also a highly toxic substance, and after entering the bloodstream, it binds to the cell's pigment oxidase, interrupting breathing, causing respiratory failure and suffocation.

80% of the world's diseases are water-related. It's really horrible.
