Specific examples of environmental damage to the planet in recent years must be detailed, accurate,

1.Antarctic ozone hole.

Due to the use of household appliances, especially refrigerators, a large amount of fluorine elements, the Antarctic ozone layer continues to disappear, so that a large cavity appears, and continues to expand, because the ozone layer can effectively block ultraviolet radiation, protect human life and health, and the destruction of the ozone layer makes the probability of human suffering from ** disease increasing year by year, making human beings more in fear...

2.The problem of nuclear radiation.

Due to the expansion of nuclear power plants, nuclear radiation is becoming more and more serious, causing pollution and destruction of resources such as water bodies and soil.

3.Garbage pollution problem.

The garbage is piled up, so that the disposal of garbage causes a lot of pollution, such as air pollution from combustion and soil pollution from landfills.

4.Wait a minute...

In a clean atmosphere, the composition of trace gases is insignificant. However, in a certain range of atmosphere, trace substances that were not originally present may have adverse effects and hazards on people, animals, plants, articles and materials. When the concentration of pollutants in the atmosphere reaches a harmful level, so as to destroy the ecosystem and the conditions for the normal survival and development of human beings, the phenomenon that causes harm to people or things is called air pollution.

The causes of air pollution are both natural and man-made factors, especially human factors, such as industrial exhaust gases, combustion, automobile exhaust and nuclear emissions. With the rapid development of human economic activities and production, while consuming a large amount of energy, a large amount of exhaust gas and soot substances are also discharged into the atmosphere, which seriously affects the quality of the atmospheric environment, especially in densely populated cities and industrial areas.

formation of lactomar eutrophication; mercury poisoning in Japan; Fluoride destroys the ozone layer; deterioration of the ecological environment of the Aswan Dam; the evil results of the application of "666" and "DDT"; The "greenhouse effect" of the planet

In 1934, the Black Storm in the western United States destroyed more than 4,500 acres of arable land; In 1963, a major storm occurred in the agricultural reclamation area of the former Soviet Union, destroying more than 300 million acres of land; The destruction of forests also led to the extinction of the ancient Babylonian civilization; The Thar Plain, between India and Pakistan, has been reduced to a desert due to deforestation, covering an area of 650,000 square kilometers; The deterioration of the ecological conditions in the Yellow River Basin in China stems from the destruction of forest vegetation in the upper reaches of the Yellow River, and the Yangtze River will become the second Yellow River. The deterioration of ecological conditions in the northeast forest area is mainly due to the unreasonable logging and over-logging of forests in the southwest and northeast forest areas.

Forest pests and diseases caused by overhunting natural enemies of insects;The killing of otters in India has led to an increase in diseased fish and a decline in fish productionIn Australia, where animal husbandry is developed, dung beetles are infested due to cow dung covering grasslands.

Garbage pollution.

Garbage encroaches on land, blocks rivers and lakes, hinders hygiene, affects the landscape, and endangers the growth of crops and human health, which is called garbage pollution.

Garbage includes two parts: industrial waste residue and domestic waste. Industrial waste residue refers to the waste generated in the process of industrial production and processing, mainly including coal grinding stone, fly ash, steel slag, blast furnace slag, red mud, plastic and petroleum waste residue. Domestic garbage is mainly kitchen waste, waste plastics, waste paper, broken glass, metal products and so on.

In cities, due to the increasing population, domestic waste is increasing at a rate of 10 per year, posing a major public nuisance.

The serious harm of garbage is, first of all, the encroachment on a large amount of land. The second is to pollute farmland. The third is to pollute groundwater.

Fourth, air pollution. Some organic substances in industrial waste residue can produce foul odors through biological decomposition at a certain temperature, thereby polluting the atmosphere. Fifth, the spread of diseases.

Domestic garbage contains germs and parasites, and if it is directly used as fertilizer for farmers, people may get infectious diseases if they eat vegetables, melons and fruits that have been applied to this fertilizer.

With the development of the economy and the improvement of people's lives, urban garbage has increased significantly. Garbage disposal has become an urgent problem in the comprehensive improvement of the urban environment.

Historically, there used to be a large area of forest on the Loess Plateau in China, but it was cut down in large quantities during the Qin and Han dynasties. Soil erosion on the Loess Plateau.

Earth, my mother. How great you are, you have nurtured us as human beings, and you have selflessly provided humanity with the water it needs ... And we are wreaking havoc on you, abusing chemicals, and changing your beautiful and magnificent face beyond recognition.

You're scarred. What you never expected was done by the thousands of children you raised. Rest assured, Mother Earth, you will not be hurt again, because I want to declare to the world that "to protect the earth is to protect yourself".

We should protect nature's air, soil, mountains and rivers. Trees and animals that protect nature, especially rare plants and animals. Conservation of nature's resources ......

To protect nature is to protect the environment on which human beings depend, and everyone must care about it and do their best.

Let's take action quickly to protect our planet. We should lead by example and not throw garbage away. If everyone throws away a little garbage, the earth will be full of garbage, and the earth will be hopeless.

If everyone planted a tree, it would add a lot of green to the earth, and then our home Ashishi Garden would become a green paradise.

Once we didn't know how to cherish, now we can't regret it, if we can do it all over again, we must protect the earth.

1.Soil erosion on the Loess Plateau.

In addition to some natural causes, the main human causes are the irrational use of land by human beings, the destruction of ground vegetation and stable terrain, and the rapid population growth leading to acute contradictions between man and land.

2.Desertification of land in the northwest.

Human activity. The pressure of population growth on land is the direct cause of land desertification. Overgrazing, extensive management, blind reclamation, irrational use of water resources, excessive deforestation, and unreasonable mining in arid land are the main manifestations of accelerated desertification expansion by human activities.

Indiscriminate digging of Chinese medicinal materials and deforestation are human activities that directly lead to land desertification. In addition, irrational irrigation methods have also caused secondary salinization of cultivated land.

Geographical and climatic factors.

Arid and semi-arid and sub-humid arid regions are located deep in the hinterland of the continent, and are the most arid and fragile environmental zones with the least precipitation and the largest evaporation in the same latitude in the world. Desertification develops when the climate dries out, and when the climate becomes wetter, desertification reverses. In recent years, sandstorms that frequently occur in northwest China and north China (north) have aggravated the desertification process in these areas.

In addition, there are also things like the degradation of wetlands in Northeast China and the salinization of land in North China.

Hope it helps

Examples of how humans have been destroying nature are as follows:

1. Overgrazing; 1 3 of the world's rangelands are being drastically degraded due to overgrazing, which is the leading cause of land degradation. Among the countries with the greatest damage and the largest proportion of overgrazing, Pakistan, Sudan, Zambia, Somalia, Iraq and Bolivia are the most affected.

Often, the first sign of unsuitable pasture management is the disappearance of the most delicious herbs and grasses.

2. Excessive reclamation; Rapid population growth has made food shortages an increasingly obvious problem. As a result, humans have destroyed forests and grasslands on a large scale. However, irrational land reclamation and cultivation have caused large-scale soil erosion, desertification, and sandstorms.

3. Enclosing the lake to create fields; Since 1960, China's Honghu, Poyang, Dongting, Dianchi and other lakes have been reclaimed on a large scale, which has exacerbated the environmental and ecological deterioration of the lake area. Honghu Lake in Hubei Province, in 1964, there were still 10,000 acres of paddy fields, and the total amount of 300,000 acres after many rounds of the lake, and the existing water surface was 530,000 acres.

Due to the decrease of lake capacity, the disaster control and storage function of the lake area is seriously weakened, resulting in frequent waterlogging disasters in the flood season, deterioration of the soil environment of low lake fields, and a decrease in efficiency.

Relationship with the natural environment:

On the one hand, we need to ask the natural environment for all kinds of materials and energy we need for survival and development, including air, water resources, mineral resources, land resources, biological resources, and so on.

On the other hand, in the process of using various substances and energy from the natural environment, some wastes will be generated, which cannot be reused and digested within human society, so they need to be discharged into the natural environment.

When human beings take too much material and energy from the natural environment, they often produce problems such as resource shortage and ecological damage. When human beings discharge too much waste into the natural environment, thus exceeding the self-purification ability of the natural environment, environmental pollution problems often occur. <>
