Human civilization may face a major threat before 2050. What should we do?
These fossil energy sources will bring a lot of greenhouse gas emissions and other harmful gas emissions, coupled with the pollution caused by a large number of garbage generated by the increasing population, the ecological environment of the earth is deteriorating step by step. I believe that in recent years, with the global temperature rising and natural disasters increasing, you can also feel it.
Maybe we ordinary people don't really understand the impact and threat brought by the deterioration of the ecological environment. People still continue to destroy the environment and don't take it seriously. They think that such a huge earth is not bad for themselves. However, for scientists who are at the forefront of human civilization, they are very worried about the great threat brought by the deterioration of the ecological environment to human civilization, and some scientists even put forward serious warnings.
Some time ago, scientists made a simulation experiment of the disastrous consequences caused by the earth's climate change. Through simulation experiments, scientists have come to a terrible conclusion: human civilization may collapse completely before 2050. Why did scientists come to such a terrible conclusion? Mainly through the statistical analysis of the current global temperature rising trend.
The main reason for the global temperature rise is that the carbon dioxide emission brought by industry makes the carbon dioxide in the atmosphere rise continuously. In recent 10 years, all countries in the world have strengthened environmental protection and carried out various purification treatments for chemical plants with serious carbon dioxide emissions, which has led to the continuous reduction of carbon dioxide emissions and the continuous improvement of emission standards for automobile and other exhaust gases. However, in 20 19 years, scientists found that the content of carbon dioxide reached a new high by detecting atmospheric components. In other words, our efforts over the years have not reduced carbon dioxide emissions, but accelerated them. Why?
In fact, if you think about it carefully, you will understand that although various environmental protection measures have been continuously introduced and various purification treatments have been added to industrial production, the pace of human science and technology development is accelerating, and the subsequent industrial production is also accelerating. Although the quality has improved, the quantity is also exploding. Taking fuel vehicles as an example, the emission standard of exhaust gas has been greatly improved compared with that of 10 years ago, but now the number of vehicles is many times that of 10 years ago, and the total emission of exhaust gas has increased.
In addition to the carbon dioxide emissions caused by industrial production, there are other human activities that have also aggravated the global temperature rise, such as the acceleration of urbanization. Some people may not understand why the acceleration of urbanization will raise the global temperature. The reason is actually not complicated. Imagine that high-rise buildings, asphalt roads and other materials in the city have the function of absorbing heat. After heat is absorbed, it is released into the atmosphere at night, making the surface a steamer. It is strange that the weather is not hot.
The impact of global temperature rise will become more and more obvious and serious. Perhaps in many people's cognition, the global temperature rise is nothing more than unbearable heat in summer, as long as we turn on the air conditioner during the day or don't go outdoors. But is it really that simple? Of course not. The impact of global temperature rise is terrible.
Perhaps the current global temperature has not yet reached the time of natural disasters, but with the increase of temperature, once it breaks through a critical point, the real disaster will come. Researchers say that if the average temperature of the earth continues to rise by 2℃, most parts of the world will face the threat of drought and desertification, and the land of 1/3 of the world and 55% of the population will suffer from deadly high-temperature heat waves, which is enough to cause a devastating blow to human civilization today.
As the temperature rises, tropical and subtropical regions will be seriously affected first. There will be severe drought and fire, and many virgin forests may disappear because of the fire. I believe everyone knows the biggest Amazon rainforest fire in the world this year. In fact, in recent years, fires have occurred in these virgin forests every year, and they are on the increase.
By then, the Amazon rainforest, the Arctic Circle and coral reefs will be completely destroyed in this catastrophe. However, serious desertification will occur in southern Africa, southern Mediterranean and western Asia, and China will also be affected by severe drought. At the same time, the summer monsoon may disappear, and the resulting disaster is very serious.
Once such a disaster occurs in this region, the whole world will face a devastating impact, and there will be no crops in areas that were originally suitable for crop growth, which will lead to global famine and turmoil. On the other hand, the food crisis will have a serious impact on the country itself, making it face an unprecedented humanitarian crisis.
This is the influence of the ground. What about the ocean? As many people know, the global temperature rise will cause the continuous melting of global glaciers, and the subsequent consequence is the rise of sea level. Some scientists have said that if all the glaciers in the world melt, the sea level may rise by about 50 meters. At that time, the global flood that occurred in ancient times will come again, most of the land will be submerged, and the earth will usher in a new round of extinction.
In fact, the catastrophe caused by the rising temperature of the earth occurred in the dinosaur era. At that time, the rising atmospheric carbon dioxide led to a sharp rise in global temperature, which led to the melting of global glaciers and global flooding. Scientists found some evidence by finding many ancient fossils. Some scientists even think that the extinction of dinosaurs may not be caused by asteroid impact, but by the global flood.
Global temperature rise will revive ancient bacteria and viruses that have been frozen for tens of thousands of years, which is an unknown threat to the earth's ecological environment and human beings. It can be seen that scientists warn that mankind may encounter a huge crisis before 2050, not without certain scientific and technological basis.
If the global temperature continues to rise at the current rate, it is entirely possible to raise the temperature to a terrible level within a few decades. At that time, the earth's ecosystem will collapse, and the real crisis will come. Of course, decades later, human science and technology will certainly go further and make greater progress and development.
With the help of science and technology, human civilization will not be threatened by global floods or other natural disasters, but it may still be severely damaged. If land rarely fails to meet the needs of human survival, we can only build a marine city to live in. Of course, it is not difficult for technologically advanced human civilization to build a marine city.
No matter what happens in the future, human beings want to deal with all kinds of disasters that may occur. We can only rely on science and technology. As long as science and technology are sufficiently developed, we can cope with global sea level rise or other natural disasters. Even if the earth's environment deteriorates to the point where it can't survive in the future, we can emigrate to other livable planets, provided that we master interstellar navigation technology.
