Many provinces in China will be hit by extreme weather. Why have extreme weather appeared frequently recently?

Extreme weather does not appear for no reason, and it must be related to human behavior.

1, extreme weather belongs to a kind of natural weather in nature.

Natural meteorology refers to wind, rain, hail and even tsunamis and earthquakes, which are natural laws and no one can avoid.

In other words, extreme weather can happen anytime and anywhere in nature, but the frequency of occurrence is related to human behavior. In the 1980s and 1990s, technology was underdeveloped and environmental damage was not serious. At that time, extreme weather was rare, only once every few years, but now extreme weather basically occurs once in the first half of the year or several months.

2. The behavior of human destroying the environment leads to the frequent occurrence of extreme weather.

At present, the most obvious feature of extreme weather is the frequent occurrence of sandstorms, which is mainly related to human behavior. Nowadays, people do not hesitate to destroy the environment for social and economic development, which is followed by extreme weather, such as sandstorm and unstable temperature.

It may be 30 degrees today, but it will be 20 degrees tomorrow. According to common sense, this cliff-like cooling should not occur.

Secondly, people cut down trees indiscriminately, which leads to the imbalance of ecological environment and creates good conditions for sandstorm weather. Sandstorm has two conditions. First, the airflow is strong. Second, desertification in this area is serious, and the final result of deforestation is the gradual spread of desertification.

If you want to prevent extreme weather, you can't destroy the environment.

Although extreme weather is a kind of natural weather, we can reduce the frequency of extreme weather through human efforts. In recent years, in some areas with serious desertification, planting trees and grass has been effectively controlled, and sandstorms have been prevented to some extent.

People try to travel by public transport and don't pollute the environment. Once the environment is polluted, it is difficult to control.

Generally speaking, extreme weather control, 10 day and a half can't be cured. It takes a long time to improve slowly, even the efforts of generations.
