What environmental problems are seriously endangering human health?

1. The harm of air pollution.

A person needs to breathe air to stay alive. An adult breathes about 20,000 times a day and inhales 15 20 cubic meters of air. Therefore, polluted air has a direct impact on human health.

The harm of air pollutants to the human body is multifaceted, manifested as respiratory system damage, physiological dysfunction, digestive system disorders, nervous system abnormalities, mental decline, carcinogenesis, and disability. People call the smoke of this catastrophe the smoke of murder.

When the concentration of pollutants in the atmosphere is very high, it can cause acute pollution poisoning, or worsen the symptoms, and even kill thousands of people in a few days. In fact, even if the concentration of pollutants in the atmosphere is not high, the human body breathes this polluted air for many months, which can cause diseases such as chronic bronchitis, bronchial asthma, emphysema and lung cancer.

2. Garbage pollution.

In the garbage, toxic gases are dispersed with the wind, and the content of sulfur dioxide and lead in the air increases, which increases the incidence of respiratory diseases and poses a carcinogenic hazard to the human body. Excessive levels of pollutants in groundwater can cause diarrhoea, schistosomiasis, trachoma, for example, an epidemic of dysentery in Guiyang City, which is caused by the infiltration of groundwater by landslides and the serious exceedance of E. coli.

3. Water pollution.

Harm to people, if people drink polluted water, it will cause acute and chronic poisoning, cancer, infectious diseases and some other strange diseases, and the sensory deterioration caused by polluted water will cause inconvenience to people's lives and adversely affect their emotions.

Environmental issues. There are many kinds of them, and they can be summarized into two main categories:

One category is natural evolution and natural disasters.

The original environmental problems caused by them are also called the first environmental problems. Such as **, floods, droughts, typhoons, collapses, landslides, and mudslides.

Wait. The first is the secondary environmental problems caused by human activities, also known as the second environmental problems. Secondary environmental problems are generally divided into two categories: environmental pollution and ecological damage.

For example, the destruction of forest vegetation caused by indiscriminate logging, the degradation of grasslands caused by overgrazing, the desertification and desertification of land caused by large-scale grassland reclamation, and the deterioration of the atmospheric and water environment caused by industrial production.

So far, the environmental problems that have threatened the survival of mankind and have been recognized by mankind are mainly as follows:

Global warming. Ozone layer depletion, acid rain.

Freshwater resource crisis, energy shortage, sharp decline of forest resources, land desertification, accelerated extinction of species, garbage disaster, toxic chemical pollution and many other aspects.

Hazards: 1. Water pollution caused by all kinds of domestic sewage and industrial and agricultural wastewater;

2. Industrial smoke and exhaust gases, vehicles.

air pollution caused by the exhaust gases generated;

3. All kinds of noise pollution;

4. Pollution caused by various residues, heavy metals and wastes;

5. Soil erosion and deterioration of the ecological environment caused by overgrazing and indiscriminate deforestation;

6. Stratum collapse and soil structure damage caused by overexploitation of various underground resources;

7. Depletion of energy resources caused by the massive use of non-renewable energy.

What are the environmental problems around us and what are the dangers to people's health?

Hello pro has the following environmental problems: environmental pollution 1, environmental pollution adverse effects on organisms Environmental pollution has a very adverse impact on the growth, development and reproduction of organisms, when the pollution is serious, the morphological characteristics of organisms, the number of survival and other aspects will undergo obvious changes. The following describes the harm of environmental pollution to organisms in four aspects: acid rain, harmful chemicals, heavy metals and eutrophication of water bodies.

2. Environment and human healthWith the increasing severity of environmental pollution, many people breathe polluted air, drink polluted water, eat agricultural products grown from polluted soil, and sound ...... in their earsEnvironmental pollution is a serious threat to human health.

Environmental problems are still harmful to human health, the first is the emission of automobile exhaust, the second is the emission of pollutants from factories, and the third is the noise of the environment.

Due to environmental pollution, the harm to health is particularly great, such as plasticizers produced by plastics, waste water, and waste gas pollution.

We are affected by environmental problems every day, such as air pollution, and resource pollution.

The past one has been working well for more than a year.

It is very harmful to people's respiratory tract and body, and in severe cases, it may suffocate.

The message record of the departure of street w said that it was not acceptable, no, no, no, no!

the use of rare and protected animals, care and protection of wild animals and plants; Afforestation, take care of every inch of green space, every flower, every tree around us.

Water conservation advocates the use of a basin to wash your face, and the water used to water flowers and mops after washing your face or clothes. Take care of water-saving facilities, close the faucet, and consciously cherish water sources. To save electricity, it is recommended to use natural light as much as possible, turn off lights, computers and other electrical equipment, and turn off the power in time after use, reduce standby loss, and use electrical appliances reasonably.

Green consumption should use disposable paper cups as little as possible, advocate bringing your own water cups, less disposable plastic bags, and recommend using cloth bags, which can be used many times to reduce "white pollution". Garbage disposal garbage should not be thrown on the ground, try to put it in the adjacent trash can, but pay attention to garbage classification, mineral water bottles can be reused as much as possible. Less deforestation, more destruction, more protection, support, protect the small creatures in the forest, so that their lives can continue.

What are the dangers of environmental problems to people's health? problems, which are very harmful to people's health. For example, on the respiratory tract of people.
