North America's high temperature has reached a new high. Why is the earth getting hotter and hotter?

Since 265438+20th century, the "high fever" of the earth has continued, the global temperature has been rising year by year, and the phenomena such as greenhouse effect and forest fire have emerged one after another. Since June, the high temperature in North America has continued, not only the animals and plants have been seriously affected, but also the owner of the earth, "human", has suffered heavy casualties in this extreme high temperature.

In the United States of North America, the temperature has remained high. In the high temperature area of the United States-Death Valley, the temperature reached a "horrible" 54.4 degrees Celsius. The American people are in dire straits and ravaged by high temperatures. Now, 30 million American residents are deeply affected by extreme heat.

As a planet suitable for human habitation, why has the temperature become so high? The answer is simple. After three industrial revolutions, human beings once burned fossil fuels stored on the earth for hundreds of millions of years. Industrial waste gas produced by human production activities and a large number of greenhouse gases represented by carbon dioxide lead to more and more greenhouse gases in the atmosphere, especially the "increasingly serious" greenhouse effect, which urges the earth's temperature to rise continuously.

Why is the earth getting hotter and hotter? How terrible is the "greenhouse effect"? Most of us can deeply feel that since the end of last century, the average temperature has increased year by year, and the greenhouse effect has become more and more serious. At the end of last century, even in hot summer, the temperature rarely reached above 30 degrees Celsius. In most parts of China, the summer temperature often stays above 30 degrees Celsius. After the dog days, there are often "extreme" high temperature weather above 35 degrees Celsius.

The chief culprit of this situation is the "greenhouse effect". In the next few decades, if human beings continue to emit greenhouse gases, the greenhouse effect will show a "terrorist" side, the temperature of the earth will continue to rise uncontrollably, and the annual average temperature will continue to rise, which will have a great impact on human beings.

The impact of rising temperature goes far beyond the discomfort of human life, but problems such as melting glaciers and rising sea levels will seriously threaten the lives of people in coastal countries and regions. Not only that, the original bacterial viruses sealed under the ice sheets of the North and South Poles hundreds of millions of years ago will also be "released" with the melting of the ice sheets, which will have a huge and even "devastating" impact on human beings. If human beings don't stop, the film Resident Evil will be staged.

Our earth is not only inhabited by human beings, but also contains more animals and plants than human beings, and a huge biosphere built by mountains and lakes. All species on the earth are "fate", which has such a bad influence on human beings, and the biological cycle effect will be extremely terrible. Nowadays, science and technology restrict human survival on the earth, which will lead to the inability of human beings to "muddle through".

We have known since childhood that plants can absorb carbon dioxide in the atmosphere through photosynthesis and convert it into oxygen, and the Amazon rainforest, the largest tropical rain forest on earth, is in danger of disappearing.

The Amazon rainforest is cut down in an area equivalent to four new york. The tropical Amazon rainforest is called "the lungs of the earth". The oxygen it produces every year supplies a large part of the living things on the earth, which has a great regulating effect on the earth. Nowadays, the influence of human activities on the Amazon rainforest is increasing day by day. The Amazon rainforest has been severely cut down, and the living environment of animals and plants has been seriously threatened!

Nowadays, the global environment is deteriorating, but the amount of deforestation in the Amazon region is increasing year by year. In just seven months in the first half of this year, the amount of deforestation in the Amazon rainforest exceeded 17% compared with the same period. "Shocking" data tells us that the Amazon rainforest is being "destroyed" by human hands.

In the first half of this year, the amount of deforestation in the Amazon rainforest reached an astonishing 36 10 square kilometers. In new york, the United States, in half a year, the Amazon rainforest was cut down by human beings for four new york!

However, this phenomenon will not stop in a short time. If logging continues at this rate, it is estimated that the entire Amazon rainforest will lose about 12 new york after the end of this year. There is an old saying in China that "it takes ten years to plant trees, but it takes a hundred years to cultivate people". It takes at least ten years to cultivate a tree, which is only the waiting time after afforestation, and the overall speed of human afforestation has long been unable to keep up with the disappearance of forests after being cut down.

The greenhouse effect is getting more and more serious, but the trees that can alleviate this disaster are being cut down, and the number is decreasing year by year. Such a vicious circle will push mankind to a "dead end", and animals and plants on the earth will suffer.

Many experts and scholars have pointed out that the decade from 202 1 to 203 1 will be a crucial period to determine the fate of mankind. If mankind still fails to find an effective way to alleviate the greenhouse effect during this period, the situation of the earth will "turn sharply" and the fate of mankind, animals and plants will be "unimaginable"
