Hundreds of years ago, after more than 5,000 years of continuous development, human civilization finally embarked on the path of technological development. Technology has freed our hands and entered the industrial age from the handicraft era. The power of industry has given wings to human civilization and can fly higher, faster and farther.
Mankind has also enjoyed a lot of benefits brought by technology. It can be said that each of us is very grateful for technology. Mankind is grateful for the health, convenience and endless benefits brought by technology. But for nature, it dislikes technology very much, because the rapid development of industry has brought more and more serious consequences to the ecology of the earth.
We all know that the ecology of the earth is very perfect. Although there have been many ecological drastic changes in history, they are all natural and normal evolutions. However, the ecological changes brought about by human industry are obviously abnormal. In just over 200 years since humans entered the industrial age, the earth’s environment can be said to have been deteriorating.
Industry can generate a large number of greenhouse gases and various pollution sources. Greenhouse gases have caused the greenhouse effect to intensify and the global temperature continues to rise. Some people may think that the temperature of the earth has risen, but we will feel the heat. However, human beings have the power of science and technology. The rooms where we live can be cooled by various means such as air-conditioning without causing too much harm.
If you think so, you are wrong. The heat caused by rising temperatures is only a manifestation of the first stage of the greenhouse effect. The truly terrible disasters have not yet come, but with the advancement of industrialization, global warming is also increasing. According to some reports published by scientists this year, the earth may experience an unprecedented warming in the next 50 years. process.
In 50 years, in 2070, more than one-fifth of the earth will become as hot as a desert. At that time, one-third of the earth’s population may experience extreme heat, and people’s lives will become very sad.
Regarding the Earth’s climate change in the next 50 years, scientists are not completely guessing. Instead, a number of scientists have participated, referring to climate change data obtained from archaeology and various historical records since written records. By inputting these data into a computer model, simulations have obtained huge changes in the earth’s climate in the next 50 years.
The simulation results show that if mankind does not strictly control greenhouse gas emissions in the next few decades, then mankind will encounter unimaginable serious consequences in 50 years. According to research, there will be at least 20% of the land at that time, and the climate will rise to a hot climate similar to the Sahara Desert.
It should be understood that the average temperature of the Sahara Desert is higher than 29 degrees Celsius. If these lands become such an environment, it means that the average temperature will be higher than 29 degrees Celsius.
At a temperature higher than 29 degrees Celsius, only 0.8% of the Earth’s area currently conforms to it, and this average temperature area can be regarded as a forbidden zone for life, and it is a terrible condition not suitable for human survival. There is not much land on the earth, accounting for only 29% of the world’s area, and one third of it is desert.
If another 20% of the land is not suitable for human survival in 50 years, then we will have fewer places to live, and we must not forget that the global population is also increasing. The current global population is more than 7 billion. By 2070, it may increase to 10.5 billion.
Some people may say that rising global temperatures may not necessarily reduce the land available for human survival. You must know that the North and South poles used to be land of ice and snow, and the temperature was very low, which is not a good place for human survival. However, as the temperature continues to increase, 50 years later, the temperature in the north and south poles may be very mild, and large tracts of land can be suitable for human survival.
So is Harvest really that simple? That’s right, the large areas of land in the north and south poles are very likely to become a warm place in 5 billion years due to rising temperatures. The warm climate is indeed suitable for human survival, but at that time will we migrate to the north and the south in large numbers? The possibility is very small, why is this?
As we all know, the north and south poles are the two coldest regions on the planet, which have been covered by snow and ice in the past. The earth’s temperature is constantly rising, and the ice and snow at the poles are also melting. After 5 billion years, all the ice and snow will melt, and there will become a huge lake and ocean. Especially the bottom of Antarctica is basically located in the ocean. Once it all melts, Antarctica will become more of an ocean.
Instead, the Arctic is a large area of land, but these land is basically ancient permafrost. I believe many of my friends have heard of the permafrost layer. It has been continuously formed after tens of millions of years of extreme cold weather. It is not only a piece of frozen soil, but also a natural giant biological museum.
In the permafrost, not only a large amount of methane and other greenhouse gases are sealed in ice, but also a lot of ancient biological corpses. More importantly, there are scary ancient bacteria and viruses of unknown quantity and unknown species in the permafrost. We all know the horror of viruses. Since ancient times, viruses have always been the most terrible enemy of mankind.
The life form of the virus looks very simple and primitive, but its spread and harm are very terrible. So far, human science and technology have no absolutely effective way to deal with various viruses. No matter how modern viruses mutate, they are always within our comprehensible range, and we can quickly develop methods and drugs to deal with them.
However, the ancient viruses tens of thousands of years ago are very different from the current viruses, and they may be types that we don’t understand at all. Once they are harmful to the earth’s ecology and humans, we may not have a way to deal with it. As the global temperature continues to rise, these permafrost layers in the Arctic are constantly recovering, and a large amount of methane gas is continuously emitted, making it even more dramatic. The greenhouse effect.
At the same time, frozen corpses of ancient creatures are also constantly appearing. Scientists have found many ancient bacteria and viruses in the unsealed permafrost and brought them back to the laboratory. Some of them can be revived. This shows that the vitality of ancient bacteria and viruses is far beyond our imagination, and they are very likely to wake up in large numbers as the frozen soil layer continues to melt.
It can be seen that even if the temperature in the north and south poles has risen to a level suitable for human survival in 50 years, it will be difficult for us to live here. It is possible that the Arctic at that time became a forbidden area instead, a large amount of methane was continuously emitted, various ancient creatures continued to appear, and a large number of ancient microorganisms continued to recover.
The rising global temperature will also change the earth’s ocean environment. Scientists have found that the North Atlantic warm current goes deeper into the Arctic than before the Industrial Revolution. This means that warmer waters will reach farther north and will change the temperature pattern of the entire northern hemisphere together with the atmospheric circulation.
The Arctic region has become a warmer region in the future. Such changes in the climate pattern may also make the contradictions within human beings more intense. It is important to know that a large part of human resources comes from the ocean, and with the resources of land resources, humans’ dependence on ocean resources will become more serious in the future.
Changes in the climate pattern have led to the expansion of resources to the two poles, so the competition for resources in the northern hemisphere may become fierce, and resources have been the fuse of war since ancient times. Therefore, this fierce competition for resources may cause another world war to break out of mankind. The current war is very terrible. Once the outbreak evolves to the later stage, it may evolve into a nuclear war.
Once a nuclear war breaks out, it will be even worse, and it may directly degrade mankind from a technological civilization to a primitive civilization. The more serious consequence is the complete end of the entire civilization, which disappeared in the long river of history like the dinosaurs 65 million years ago.
This shows how serious the changes brought to mankind by the rising global temperature will be. And this time may not be too long, and 50 years is also very short for humans.
