What are the beneficial effects of extreme weather on our life or the survival of animals and plants?

Global warming has advantages and disadvantages, but generally speaking, the disadvantages outweigh the advantages, especially for agriculture. Due to the frequent occurrence of extreme weather events, soil drought, increased erosion, increased pests, reduced or even extinct agricultural biological species, increased agricultural costs and investment, and so on. Climate warming will lead to the shortage of water resources, the increase of pollutant concentration, the aggravation of drought and flood disasters, the melting of polar ice and snow, the rise of sea level, the flooding of coastal areas and the subsidence of the ground. In high latitude and desertification areas, due to climate warming, the soil will become loose, leading to the decline of vegetation and the increase of dusty weather. Among the above greenhouse gases, the increase of halogen carbides will also consume ozone in the stratosphere, thus reducing the ability of the ozone layer to protect people and other living things on earth from the sun's ultraviolet rays. According to a special report of the United Nations, with the global warming, drought, flood, hunger and plague will become serious threats to mankind in the 2nd1century, and the frequency of heat waves and rainfall will accelerate, so the water level will rise, and floods, landslides and avalanches will increase. The southern region, which often lacks water, will encounter more typhoons, droughts and serious desertification. As a result, agricultural output in many countries will drop sharply, and famine and epidemic diseases may occur.

Since the industrial revolution, with the rapid development of productive forces, human beings have become one of the most active factors causing global warming. If the environment can endure and recover from the slash-and-burn and deforestation in primitive times, then with the development of human civilization and the explosive growth of population, human beings greedily ask for it from nature, and the environment will inevitably retaliate against human beings. The "greenhouse effect" is the feedback of the environment to the "gentleness" of human beings. People should not forget what consequences the global average temperature rise of several degrees Celsius will bring to mankind.

"Water can carry a boat, but it can also overturn it." Climate is one of the environments on which human beings live. It breeds human life, all the hopes and dangers. As ordinary citizens, we should regard climate protection as a quality and accomplishment, because climate is related to everyone's vital interests, even life and death. We only have one earth. Only by loving the environment, protecting the climate, adjusting the relationship between man and nature, and making scientific and rational use of environmental resources can it benefit mankind and sprout future generations. If we conquer nature blindly, we can only take mankind to the "happy grave".
