Here I will take a look at the causes of pollution in the water environment.

There is a problem of water pollution.

What are the root causes of pollution in rivers and lakes? There are three main causes: exogenous pollution, endogenous pollution and loss of ecological functions of water bodies.

The first is exogenous pollution, mainly from industrial wastewater, domestic sewage and initial rainwater.

Wastewater discharged directly or secretly from factories and domestic sewage from cities are directly discharged into natural water bodies through pipe networks, or overflow into natural water bodies when sewage treatment plants are overloaded and their treatment capacity is insufficient, thereby destroying water quality and causing serious river and lake pollution. When it rains, the initial rainwater reaches the ground through the atmosphere, and when it washes the ground, it brings harmful substances such as road pollutants and heavy metals into the pipe network and discharges them into natural water bodies, further aggravating the pollution of rivers and lakes. The exogenous pollution composed of industrial wastewater, domestic sewage and initial rainwater is the root cause of water environmental pollution.

This is followed by endogenous pollution, mainly from river and lake sediment, decaying aquatic flora and fauna, and coastal garbage.

Sediment pollution is when the water body is polluted, some pollutants in the water are stored in the sediment through precipitation or particulate matter adsorption, and re-released under appropriate conditions, becoming a secondary pollution source. In addition, the decay and decomposition process of animals and plants in the water will have a certain impact on the water quality, which may cause hypoxia in the water body, which will lead to pollution. The entry of coastal garbage into water bodies will further increase pollution.

Finally, there is the loss of ecological functions of water bodies. When the exogenous pollution and endogenous pollution are too heavy, the ecological function of the water body is destroyed, the water ecological function is lost, the self-repair and regulation ability is reduced, and the pollution is aggravated, forming a vicious circle.

According to incomplete statistics, at present, more than 90% of the water bodies in cities across the country are polluted to varying degrees (data** in the "River and Lake Pollution Status and Treatment Countermeasures" released by the Water Facilities Management Institute of Zengcheng District, Guangzhou in January 2019). In addition to more scientific development of urban water environment governance, as a member of the earth, our future destiny is closely related to the development of the ecological environment, and we should treat the ecological environment like life, implement the most stringent ecological environmental protection system, and firmly follow the civilized development path of production development, affluent life and good ecology, so as to build a beautiful China, create a good production and living environment, ensure global ecological security, and provide a strong guarantee for the sustainable development of mankind in the future!

As follows:

1. Environmental damage! Pollution of the air (e.g. burning of garbage, war), pollution of water sources (e.g. chemical plants, paper mills).

2. Pollution of the ecological environment! Plants and animals face extinction (e.g., whaling, hunting of Asian elephants) and deforestation (e.g., clearing of trees, deforestation and farming).

3. The destruction of the entire earth's environment by war! The main ones: nuclear, biochemical, (conventional missiles** are not counted for the time being).

4. Request! People all over the world excavate and exploit various non-renewable resources of the earth (such as oil, coal).

Nature is the home of human life, and human survival and development must depend on the natural environment and natural resources. Due to the exploitation and utilization of nature by human beings, the original living environment has been changed, and the interdependence between man and nature has become an antagonistic relationship, the natural environment has been seriously damaged, the ecological balance has been broken, and resources have been overexploited.

Since China's reform and opening up, due to the extensive use of agricultural science and technology in agricultural production, agricultural science and technology have affected the natural environment of rural areas, the original ecology of rural areas has lost balance, the large-scale development of rural resources has caused serious waste, the relationship between man and nature has become the relationship between subject and object, the ethical order of harmonious coexistence between man and nature has been seriously damaged, and natural ecological ethics is facing a serious crisis.

The problem of environmental pollution in China is getting bigger and bigger, so what are the causes of environmental pollution in China? Let me tell you the causes of environmental pollution in my country!

What are the causes of environmental pollution in China?

1. Developed countries.

of enterprises polluting the environment have relocated to developing countries in large numbers.

In some of our places, in order to develop the local economy, a large number of such enterprises have been introduced, and various preferential policies have been given.

2. Some small and medium-sized enterprises in China do not pay attention to environmental protection.

Even the equipment that purifies pollutants is just a decoration, which is set up to cope with inspections, and it is usually discharged at will.

3. The relevant departments only pursue economic indicators and do not care about the lives of the people.

All major pollution incidents are related to the dereliction of duty of the relevant departments.

4. For the enterprises that cause pollution, the treatment is not effective. If there is a major pollution accident, it is only a symbolic fine, which does not play a warning role, and the local government even covers up and condones it.

5. The handling of foreign garbage smuggling is not effective, so that some places and some people dare to make money by engaging in foreign garbage from abroad, but pollute their own environment.

6. The blind expansion and development of the city, ignoring public transportation.

The impractical development of private cars has caused traffic jams and serious pollution of the atmospheric environment due to motor vehicle exhaust emissions.

7. Excessive use of pesticides and fertilizers.

8. Urban garbage is not properly disposed of and collected separately, resulting in garbage pollution.

How to take care of the environment

1. Do a good job of waste classification.

It is necessary to comply with the regulations on the prohibition of littering all kinds of waste, and dispose of the waste in the designated place or container, especially do not litter the waste battery, because the heavy metals contained in a waste battery are caused by it if they flow into clean water.

Pollution is very bad.

2. Resolutely prevent waste.

In learning, try to save stationery supplies and eliminate waste, for example, pencils are made of wood, and wasting pencils is equivalent to destroying the forest. In life, it is necessary to save water, paper, and use less disposable products. At work, we should pay attention to the energy saving of the computer and the printing paper.

use. 3. Handle the chewing gum well.

Although bubble gum is a very popular candy for children and is a food that is beneficial to human health, it is important not to throw the chewed gum base around, as it will stick everywhere. When eating, you can put away its wrapping paper to wrap the spit out of the gel, and then throw it into the waste bin.

4. Do not hunt or eat beneficial insects.

Don't kill wild animals at will.

In particular, don't eat the frog, a good friend of humans, because 1 frog is within 1 year.

It can eat about 10,000 insects, mainly pests.

5. Insist on greening.

It is necessary to take care of flowers and trees, not to destroy urban greenery, and actively participate in greening and tree planting activities.

6. Less electricity. When leaving the room, turn off the lights and unplug the television, stereo, computer, etc.

Environmental pollution is now generally divided into three categories: air pollution, water pollution, and pollution caused by solid waste.

Air pollution is mainly caused by various types of exhaust gases, such as industrial exhaust gases, automobile exhaust gases, other toxic gases caused by combustion, and biological exhaust gases.

Water pollution is mainly the wastewater pollution generated by various industrial processes, such as the wastewater generated by steel, petroleum, printing and dyeing, papermaking, chemical and other industries, as well as domestic wastewater.

Solid waste can produce a large amount of untreatable garbage, resulting in the occupation of the earth's space, polluted soil and water pollution, such as discarded household appliances, fluorescent tubes, computer motherboards, waste sludge and waste residue in industrial production.

The above mainly summarizes some of the main causes of environmental pollution, and of course other noise pollution.

1.The soil is destroyed.

2.climate change and energy waste.

4.Freshwater resources are threatened.

5.Chemical contamination.

6.The overexploitation of the oceans and the pollution of the coastal strips.

7.Nuclear contamination.
