Why is it that when global warming begins to occur, humanity is the first to be harmed? On what basi

Because humans are the most advanced creatures on earth, they will bear the brunt of the damage, based on the fact that human beings have a more complex physiological structure than other organisms and have a strong ability to learn.

Because global warming will cause sea levels to rise, reducing the area of human life, which is what scientists have found.

Global warming will raise sea levels, some lowlands may be submerged, the climate will change, and some populations may disappear. It has been confirmed that the sea level is rising and the temperature is rising.

This is mainly related to human activities, human beings cut down a large number of trees, burned all kinds of household waste, carbon dioxide rises, causing the ozone layer to burst, resulting in an increase in global temperatures, in the long run, all kinds of human activities will be affected.

Introduction: At present, with more and more human activities, the content of greenhouse gases in the atmosphere increases, and in many cases, the gases produced by carbon dioxide and formaldehyde will increase the temperature of the entire earth's surface and intensify the greenhouse effect. The impact of global warming on human beings is actually very large, it will cause the sea level to rise, because the temperature is too high and the icebergs will melt, and the continuous melting of the sea will increase the amount of water in the ocean.

Once the sea water increases, it will also have a certain impact on the human living environment, and many cities are already facing the threat of sea level rise. Global warming will also make heat waves invade, and the frequency of heat waves is much higher than in previous years, which will lead to an increase in the frequency of fires, and the emergence of some related diseases, and will also have a certain impact on precipitation, which will have a serious impact on the human living environment. Global warming will also cause problems for the entire ecosystem, and will have a certain impact on the survival of human beings such as air, fuel, and food.

The main cause of global warming is the rapid increase in population, when people carry out some activities, such as cutting down forests, burning trees, burning coal and oil, etc., will increase the amount of carbon dioxide in the atmosphere, which will directly affect the climate change on the earth's surface. In addition, terrestrial greenhouse gas emissions have caused the temperature difference between the continent to rise and the ocean to become smaller, resulting in a slowdown in air convection, which will increase the haze in some cities, which will also affect human health.

Global warming has become a current trend, want to slow down the problem of global warming, everyone should actively respond to global warming, daily green travel, energy-saving use of electrical appliances, green shopping, afforestation, so that can help reduce a lot of carbon emissions, but also to reduce the use and waste of plastic products, especially disposable, closed to reduce unnecessary energy waste, you can participate in some afforestation activities.

Finally, although the topic of global warming has been known for a long time, many people don't care, in fact, everyone's behavior will affect the earth's environment, so protecting the environment is what each of us needs to do.

If global warming is really realized, the environment in which human beings live will also be changed, and there will be a lot of bad weather, the sea horizon will also rise, and the glaciers and early shelter in the Arctic and Antarctic will also melt, which will release a lot of ancient diseases.

Human beings may live in a relatively hot environment, and then the temperature difference will be very large, very cold in winter, very hot in summer, and the climate is very bad, and then we humans may travel for a shorter time.

Scientists point out that warming above Celsius means that people, wildlife and ecosystems are all likely to suffer more severe consequences from climate change. Preventing global warming from exceeding degrees Celsius requires us to halve global carbon emissions by 2030 and reach net zero emissions by 2050. Currently, global temperatures are already about Celsius above pre-industrial levels.

The last four decades have seen warmer temperatures than any decade since 1850. Just this year, flooding caused by torrential rains in western Europe killed hundreds. Record-breaking heat in the Pacific Northwest also led to hundreds of deaths.

Greenland's glaciers are melting on a massive scale. Wildfires raged in the Mediterranean and Siberia. Parts of Brazil have been hit by an unprecedented drought.

A global temperature of 2 degrees Celsius would destroy at least 70 percent of coral reefs, but more than 99 percent of coral reefs would die if the temperature rises by 2 degrees Celsius. This is a devastating blow to fish schools that rely on corals for feeding and habitat. A global warming of 2 degrees Celsius will also increase the impact on food production.

Global warming is causing widespread growth of mosquitoes carrying malaria and dengue viruses. A warming of 2 degrees Celsius would cause more insects and animals to lose most of their habitat and increase the risk of forest fires, which in turn would jeopardize wildlife.
