Why are natural disasters more and more frequent in China?

China has a vast territory, complicated geographical and climatic conditions and frequent natural disasters. Except for modern volcanic activities, almost all natural disasters, such as floods, droughts, earthquakes, typhoons, wind and hail, snowstorms, landslides, mudslides, pests and diseases, forest fires, etc. It happens every year. Natural disasters are characterized by many types, obvious regional characteristics, outstanding seasonal and stage characteristics, and obvious naturalness and companionship of disasters.

For example, agriculture: Since 1990s, there have been some new features in the occurrence of agricultural natural disasters in China.

1 Climate change makes some extreme weather and climate events happen frequently, especially the development of drought situation in the north and south. For example, the flood in Nenjiang River of the Yangtze River in the last decade, the extensive drought from 1999 to 2000, the high temperature drought in Sichuan and Chongqing in 2006, the freezing rain and snow in the south in 2008, the drought in Yunnan in the winter of 2009-20 10, and the low temperature freezing injury in North China are all extreme events that have never happened in decades.

Economic globalization makes the invasion of pests and the risk of human and animal diseases increase sharply.

Natural disasters in China have four basic characteristics: First, there are many kinds of disasters. Except volcanoes, all natural disasters exist in China, including floods, droughts and earthquakes. Second, it is widely distributed. In China, more than 70% of the cities and 50% of the population are threatened by earthquakes, floods, oceans and other disasters. Third, the frequency of occurrence is very high. Affected by monsoon climate, some major climate disasters, especially regional floods and local disasters, are very serious, and basically floods or droughts occur every year; In addition, because China is located at the intersection of the Pacific Ocean, Asia-Europe and Indian Ocean plates, earthquakes often occur. The Yushu earthquake was interpreted by experts as the result of the interaction between the Indian Ocean plate and the Eurasian plate. Fourth, the disaster losses are very serious.

In recent years, due to the influence of global climate change, extreme climate often occurs, so some disasters often occur; In addition, due to crustal movement, the risk of earthquakes has also increased.

These are all theoretical things, in fact, I think it is because of the contradiction between human economic activities and the natural environment. Of course, with the development of mankind, contradictions are becoming more and more prominent. Not only China, but also other countries are suffering from frequent natural disasters. It is not the end of the world, but if the situation continues like this and mankind does not take effective measures, the end of the world will come and mankind will get the punishment it deserves. If it is too late, it will be too late.

There will be a big change on the earth, which will rebalance the unbalanced things. The extinction of dinosaurs indicates that too powerful creatures will be eliminated. If human beings don't converge, maybe the next creature to disappear is themselves.

No one can judge whether Maya's prediction is correct. But this spirit of worrying about the end of the world is absolutely rational and worth thinking about.

Whenever I think of the word doomsday, I will deeply reflect on my behavior. My heart will tremble when I see people and animals suffering from disasters.

You must be thinking about this problem, too. ......

Let us be responsible for our actions!
