How much impact do human activities have on the environment?

Human activities continue to endanger the geographical environment, resulting in the transformation of the ecological environment, and such changes in turn endanger the normal daily life and physical and mental health of human beings. Technological revolution.

It has promoted the productive forces of human society.

It also interferes with and damages the human natural environment, especially the ecological system.

Since the twentieth century, with the rapid development of coal, steel, chemical industry and tourism, new cities and planning areas have continued to occur, and the urban population has increased significantly. As a result, sewage, organic waste gas, waste, and organic chemical substances such as fertilizers, radioactive elements and noise are more serious environmental pollution and cause public pollution.

Smoke Affair in London, England, Los Angeles, USA.

Photochemical pollution incident, Japanese Minamata disease, pain disease, Yokkaichi asthma and its rice bran oil incident (polycyclic aromatic hydrocarbons.

poisoned) and other important public hazards, which have taken the lives of countless people. In addition, malignant tumors that seriously endanger human life.

The increase in the prevalence and mortality of non-specific diseases has also caused us to attach great importance to it and has become a key topic of research in contemporary medicine.

The staff of natural environmental medicine uses clinical medicine, clinical medicine specialty.

and new medical education in epidemiology|The network has collected and sorted out and scientifically studied the harm of environmental elements to physical health, as well as the basic laws and methods of generation, development trend and regulation. With the development trend of environmental and ecological engineering, natural environmental medicine has gradually improved a separate course.

Protecting the ecological environment starts with me. Do not cough up phlegm, litter, open defecation, etc. Mountains and forests are the lungs of the earth, and they should be planted and protected, not cut down indiscriminately. Transportation can be ridden by sharing bicycles.

Or take a bus, try to avoid the use of private cars, and reduce carbon dioxide.

of discharge. Conserve water. In order to cherish water resources, no empty flow of tap water is allowed and bathing time is reduced; installation of water-saving faucets; Use a frugal flush toilet.

Save energy, try to avoid the use of electrical appliances, and close the door casually. Close the door of the household refrigerator at all times; Application of LED energy-saving lamps;

Purchase high-efficiency and energy-saving appliances. Turning waste into treasure, such as candy wrappers can be folded into lighting or door curtains, and old clothes can be made into mops. Applicable and participate in the ** reuse of waste paper, waste glass, waste plastic and waste metal.

Human beings have a great impact on the environment, because there will be great changes in the living environment of human beings, and because of the increasing population, it has led to serious environmental pollution, carbon dioxide emissions are getting higher and higher, causing certain damage.

The impact of human beings on the environment will definitely be unfavorable, there will be irrational use of resources, it will also change the growth of ecological species, and it will also emit a lot of toxic gases, which will lead to the greenhouse effect.

It will cause serious damage to the environment, will lead to environmental pollution, will also lead to environmental decay, and will also lead to ecological pollution, which are the effects of human activities on the environment.

Human beings are an integral part of nature, and the irrational and over-accelerated development of human society in recent centuries has made human activities the dominant negative factor affecting the stability of the natural environment in all circles on the earth.

The degradation or extinction of forest and grassland vegetation, the decline of biodiversity, the intensification of soil erosion and pollution, the emergence of the greenhouse effect in the atmosphere and the destruction of the ozone layer are all alarm bells for mankind. Human beings must be kind to nature and have some control over their own development and activities, and the harmonious development of man and nature has become one of the important contents of the scientific concept of development.

As the saying goes, "the road is walked out by people", every time people trample on the grass is an impact on the environment, and gradually you can get out of a road, it is conceivable that the impact of human activities on the environment is great.

Gases emitted from industrial production and automobile exhaust have led to the greenhouse effect, and the global temperature is rising; Indiscriminate deforestation has led to soil erosion, exacerbated desertification, changed the distribution of surface water, and led to severe arid climates in some areas; There are two kinds of impacts of human activities on the climate caused by acid rain caused by industrial sulfur-containing gases: one is the unconscious impact, that is, the impact of human activities on the climate; One is to consciously change climatic conditions for a certain purpose, to take certain measures. At this stage, the first type of influence is overwhelmingly dominant, and this effect is most significant in the following three aspects, namely: 1

Greenhouse gases and various pollutants emitted into the atmosphere during industrial and agricultural production.

The impact of human activities on the environment is still relatively large, otherwise, there will be no global warming, the greenhouse effect, the thinning of the ozone layer and other adverse changes.

For example, industrial pollution is a great impact on the environment, because the clear river water is also very turbid, and there are special plastic lunch boxes when going out for a picnic, which is not easy to volatilize when thrown on the ground.

Now the impact on the environment has reached a very serious level, such as white pollution. In addition, the exhaust emissions of automobiles are particularly affected.

The existence of the earth is very important, and the existence of human beings and the earth exist in each other, human beings depend on the earth, and the earth is also dependent on human beings.

An irrational human activity is likely to lead to the extinction of a species, which will slowly threaten humans.

Polar bears are living in fewer and fewer areas, and Antarctic penguins are becoming strained to live on land. Animals are innocent.

For example, the current greenhouse effect, I think most of it is caused by people cutting down and deforesting.

The impact of human activities on ecology has two major aspects: one is to benefit or improve the living environment of other organisms; Second, it is not conducive to or destroys the living environment of other organisms. For now, most of the activities are destructive. This destruction can be divided into two main categories:

One is direct destruction, such as excessive logging, reclamation, grazing, hunting, fishing, etc. The second is indirect destruction, such as: industrial pollution, greenhouse effect, ozone layer destruction, atmospheric warming, sea level rise, etc., destroying the living environment of organisms.

The more organisms evolve, the worse their ability to resist environmental changes (the SARS epidemic is the best example).If it is said that living things in nature will eventually die out, the death of man is certainly not the last.

The impact of human activities on the natural environment will cause serious soil erosion, sediment, gravel and gravel siltation, degradation and extinction of forest and grassland vegetation, decline of biodiversity, and the emergence of the greenhouse effect in the atmosphere and the destruction of the ozone layer.

The impact of human activities on the natural environment will cause changes in the quality of the natural environment, which in turn will affect the normal life and health of human beings.

The irrational use of nature by human beings and the environmental pollution caused by the development of industry and agriculture are all factors that cause damage to the natural environment by human beings.

With the improvement of productivity and the progress of human society, the relationship between man and the natural environment is getting closer and closer, so we must be kind to nature and control our own development and activities, so that man and nature can develop harmoniously.

1. Worship nature.

About 3 million years ago, humans began to appear, and people living in this era mainly lived by fishing, hunting and gathering, and the level of productivity was extremely low. At this stage, human beings are very dependent on the environment, and the environment has a strong restrictive effect on human beings, and human beings can only passively adapt to the environment. At this stage, human beings worship and revere nature, and the rudiments of various myths and stories and rudimentary beliefs also appear in this stage.

2. Utilize and transform nature.

By about 8,000 years ago, agricultural civilization began to appear, and when agriculture appeared, the population began to increase dramatically, because of the ability to produce, store food, and at the same time know how to cooperate, human beings have gradually become the most powerful species on the planet. At this stage, human beings have mastered certain tools of labor, possessed certain production capacity, and gradually became the masters of nature. However, the survival and development of human beings still depend on nature.

3. Conquer nature.

Around the 18th century, the beginning of the Industrial Revolution led to the rapid development of mankind again, and the population exploded. With the rapid development of science and technology, human beings are trying to become conquerors and masters of nature, using and exploiting natural resources in advance.

However, the greed in human nature makes human beings do not know how to stop in moderation, so with the overexploitation of natural resources, the environmental damage is becoming more and more serious, environmental problems are becoming more and more prominent, and the contradiction between human beings and nature is also rapidly intensified at this stage.

4. Coordinated development.

As the environment in which humans live becomes unlivable, people are beginning to realize the harm of self-greed to the environment. More and more environmental protection ideas have begun to emerge, advocating that we should change our concepts, adjust social behavior, be kind to nature, respect objective laws, coordinate the relationship with nature, and take the road of sustainable development, so that human civilization can continue.
