Is global warming really only harmful to human beings, without any benefits?

Global warming is a very bad existence, which seriously affects the ecological changes of the earth, but it is not all bad for human beings. It still has some advantages, such as promoting photosynthesis of crops, increasing production and income, and reducing viruses at high temperature.

Global warming has two sides, and there are advantages if there are disadvantages. In fact, global warming is a great increase in the amount of carbon dioxide, which is a very obvious benefit for human beings, that is, the increase in crop yield. Because crops need photosynthesis, at this time, the amount of carbon dioxide is more, and the photosynthesis of crops is stronger, so that the plants in the farmland will harvest well, even taste better, which is of great benefit to human beings who live on crops. More food can alleviate the famine problem in many areas. In addition, global warming will increase the temperature. Although it will make people feel unbearable heat on the one hand, it will also make some irresistible viruses disappear completely. Some viruses are difficult to be cured and prevented, but when the temperature rises in summer, these viruses will die one after another because they can't stand the hot weather. Therefore, the hot weather is not only unbearable for human beings, but also a difficult virus. So global warming can prevent diseases and make it difficult for viruses to survive the summer. Moreover, after global warming, the polar regions will gradually become warm and suitable, and some areas are too densely populated, so you can choose to immigrate to the polar regions, effectively alleviating the problem of high population density. It also keeps the land resources in the polar regions from being wasted, and scientists can gradually go there to study the mysteries of polar glaciers. It not only promotes scientific research, but also gives mankind a new place to live.

Therefore, global warming is also beneficial, but it can't make the global temperature rise endlessly, and it will still do great harm to mankind.
