The main cause of climate warming

The main causes of global warming are human factors and human factors.

The specific reasons are as follows:

1, population explosion factor: population explosion is one of the main factors leading to global warming. At the same time, it also seriously threatens the balance between the natural ecological environment. With such a huge population, the amount of carbon dioxide emitted by itself every year will be an amazing number, and the result will directly lead to the continuous increase of carbon dioxide content in the atmosphere, thus directly affecting the climate change on the earth's surface.

2. Atmospheric environmental pollution factors: The increasingly serious environmental pollution has become a major global problem, and it is also one of the main factors leading to global warming. The research on global climate change in 2 1 century has clearly pointed out that the temperature of the earth's surface has been rising since the end of last century.

3. Deteriorating factors of marine ecological environment: sea level changes are on the rise. According to the prediction of relevant experts, the sea level may rise by 50 cm by the middle of the next century. If no measures are taken, it will directly lead to the destruction and pollution of fresh water resources and other adverse consequences. In addition, a large number of toxic chemical wastes and solid wastes produced by land activities are continuously discharged into the sea; Major oil spills in seawater and the destruction of coastal ecological environment by human activities are the main factors leading to the destruction of seawater ecological environment.

4. Land destruction factors: the main cause of soil erosion and desertification is inappropriate agricultural production. As we all know, good vegetation can prevent soil erosion. However, by the current year of 20 14, due to excessive deforestation, land reclamation for agricultural production and overgrazing, human activities are still seriously destroying vegetation. Land desertification, 40-70 thousand tons of soil erosion. Soil erosion reduces soil fertility and water retention, thus reducing soil biological productivity and its ability to maintain productivity; It may also lead to large-scale floods and sandstorms, causing huge economic losses to society and deteriorating the ecological environment.

5. Factors of sharp decline of forest resources: Worldwide, due to natural or man-made factors, the forest area has decreased sharply.

6. Hazard factors of acid rain: The impact of acid rain on the ecological environment has attracted more and more attention from all countries in the world. Acid rain will destroy forests, acidify lakes and endanger living things. In the 20th century, acid rain around the world was mostly concentrated in Europe and North America, and most of them occurred in developed countries. In some developing countries, acid rain also occurred and developed rapidly.

7. Factors that accelerate species extinction: Life on earth is a precious resource for human beings, and the diversity of life is the basis for human survival and development. But the biological species on the earth are disappearing at an unprecedented rate.

8. Water pollution factor: According to the water quality monitoring project of Global Environmental Monitoring System, about 65,438+00% of the monitored rivers in the world are polluted. Since the beginning of this century, the water consumption of human beings is increasing rapidly, and the scale of water pollution is also expanding, forming a contradiction between supply and demand of fresh water. Therefore, the treatment of water pollution will be very urgent and important.

9. Toxic waste pollution factors: The increasing toxic chemicals not only pose a serious threat to human survival, but also bring harm to the ecological environment on the earth's surface.
