Information on human destruction of the planet, concrete examples

There are various classifications of environmental pollution:

According to environmental elements: air pollution, water pollution, soil pollution.

According to human activities, it is divided into industrial environmental pollution, urban environmental pollution, and agricultural environmental pollution.

The Songhua River in my hometown was polluted with benzene from the Jilin Chemical Industry.

Alternative environmental damage – the invasion of alien organisms that destroys the local ecological environment. For example, the problem of a yellow flower in Shanghai now, and the flooding of water hyacinth in the Huangpu River a few years ago.

1. Human destruction of the earth is mainly manifested in two aspects: ecological destruction and environmental pollution.

2. Cases: (1) Ecological destruction: the Amazon rainforest has been cut down on a large scale, affecting global climate change; Soil erosion and salinization of the land.

2) Environmental pollution: smog in China; water pollution in Kazakhstan caused by oil spills in coastal areas; Garbage siege incident.

3. Knowledge expansion: Ecological damage refers to the phenomenon that the natural ecological environment such as forests and grasslands is destroyed by the irrational development and utilization of human beings, thereby deteriorating the living conditions of humans, animals and plants. Such as:

Soil erosion, land desertification, soil salinization, loss of biodiversity, etc.

4. Environmental pollution refers to the behavior of natural or man-made destruction, adding a certain substance to the environment and exceeding the self-purification ability of the environment. (Or due to human factors, the environment is polluted by harmful substances, so that the growth and reproduction of organisms and the normal life of human beings are adversely affected.) The phenomenon of changing the composition or state of the environment due to human factors, and the decline of environmental quality, thereby disturbing and destroying the normal production and living conditions of the ecosystem and human beings.

1. Ecological destruction, the Amazon rainforest has been cut down on a large scale, affecting global climate change, soil erosion and salinization of the land;

2. Environmental pollution, China's haze weather, water pollution caused by oil spills in coastal areas, garbage sieges;

3. Soil destruction, in Africa, Asia, and Latin America, due to the disappearance of forest vegetation, overexploitation of arable land and overgrazing of pastures, soil denudation is very serious. The exposed land has become fragile and unable to withstand the erosion of wind and rain for a long time. In some places, the annual loss of soil can be as high as 100 tonnes per hectare.

The excessive use of chemical fertilizers and pesticides, the fall of toxic dust associated with air pollution, the spraying of mud everywhere, and the discarding of hazardous waste everywhere all contribute to the general irreversible pollution of the land;

4. The greenhouse effect is a common name for the atmospheric thermal insulation effect. The atmosphere can make the solar short-wave radiation reach the ground, but the large liquid and the amount of long-wave thermal radiation released from the surface after heating are absorbed by the atmosphere, and the greenhouse effect leads to global warming, the increase of pests and diseases on the earth, the rise of sea level, and the desertification of the land.
