The trouble has just begun. Hawking is right to worry. What will the future of mankind be like in 2021?

The whole year of 2020 has allowed each of us to develop a very good habit, which is to wear a mask at all times when going out. It can not only keep warm and isolate dust in the air, but more importantly The best thing is that it can prevent the invasion of virus-carrying droplets.

No matter where we go, when taking a car or visiting a shopping mall, we need to show our health code. An epidemic has completely changed our living habits. Fortunately, when the virus is raging around the world, our lives It is relatively normal and has not been greatly affected;

This is due to the unsung heroes who are selfless and dedicated at the front, and also due to the active participation and participation of each of our ordinary people. conscious.

Just when everyone was relaxing and preparing to go home for the New Year, the virus began to rebound again, once again making us feel the nervousness we felt during the New Year last year.

My girlfriend asked just now, what if I can’t go back this year? It's been a whole year. When will this end? I told her: This disaster is far from over. As long as the international epidemic is not effectively controlled, no one can say when it will end, and the troubles for us humans in the future have just begun.

She said that she must be at home early for the Chinese New Year next year. This suddenly made me feel like this was a bit endless.

Because we humans are a whole in the face of viruses. As long as there is still one virus carrier in the world, the epidemic will not end. It was the same as when humans eliminated the smallpox virus in 1975 and 1977. Two patients who naturally carried smallpox were cured;

After the entire population was vaccinated against smallpox, mankind declared victory over smallpox in 1980. This was the first time that humans had completely won a battle against a virus. However, the process of defeating smallpox lasted 3,000 years, and humans paid the price of hundreds of millions of lives.

So, if we want to completely get rid of the troubles of this virus disaster, the only way now is to achieve comprehensive vaccination work around the world and completely eliminate the living space of the virus. Only then can we win. This battle.

Looking at the current international situation, what do you think will happen in 2011? It can be estimated that today will still take a year of hard work, and we still cannot relax.

But humans in the future will encounter more troubles, which are inevitable for the normal development of mankind, and these troubles are catastrophic and may even affect the survival of mankind.

1. This virus will be with us for a long time. We should always stay vigilant and pay attention to protection in our lives.

The reason has been mentioned above. Only when we completely cure the last virus carrier and fully vaccinate can we declare victory. After all, this cannot be accomplished in a short period of time.

2. Human beings will encounter the same problem in the future;

Although the life forms of microorganisms are not advanced, they are the oldest, most tenacious and species on the earth. The most abundant and widely distributed life; and they mutate and innovate very quickly;

So from these perspectives, they are more like the masters of the earth, because most of their way of survival is based on boarding. Lord, so as long as we humans exist, as long as these microorganisms exist, we are at risk of being invaded again by new viruses.

Throughout history, these microorganisms have caused far more casualties to humans than any disaster or war. They have even shaped the development trend of human society. Therefore, we often say that the history of human development is A history of the fight against microorganisms.

Such struggles will not diminish in the future, and they will always be a trouble for mankind. In addition to the threat of microorganisms, there are also problems with human development.

3. Environmental pollution, greenhouse effect

Air pollution, water pollution, and white pollution have now become the most troublesome problems for human development. In big cities, if you stand high up, you will see a layer of gray haze covering the entire city under the blue sky.

These hazes are tiny particles that are difficult to disperse. They will enter the human lungs through breathing, and even the circulatory system and cells of the body. Human beings have to breathe every moment. It would be fatal damage to us.

A paper last year showed that carbon particles and metal particles in car exhaust and industrial emissions have entered the human placenta, and are inhaled through our lungs.

Water resources, like the atmosphere, are basic to the earth's ecology. Which living thing can get rid of the need for water? If there is a problem with the water itself, the living things on the earth will naturally not be able to survive.

White pollution has become more and more serious in recent years. Scientists have discovered that the plastic waste thrown away by humans is not only difficult to be decomposed naturally, but what is even more dangerous is that these white plastics will release micron-level particles and enter the living body. As a member of the biological chain, human beings are naturally unavoidable.

A 2019 paper has revealed that plastic particles have been found in human feces, and a paper last year showed that plastic particles, like carbon particles and metal particles, have entered the human placenta.

Now we know why in recent decades, we would rather lose economic benefits and lose money to keep green mountains and clear waters, because it is urgent to deal with environmental pollution problems.

While human carbon emissions cause air pollution, they also bring about an unimaginable greenhouse effect, causing global temperatures to rise by 1.5 degrees Celsius compared to before the industrial era.

The current lowest temperature of -71 degrees Celsius in the Arctic Circle no longer exists. The current lowest temperature is -50 degrees Celsius, which has caused a large number of glaciers to melt and the permafrost to melt. The color of the land and rocks has even appeared in the Arctic. Green, revealing many islands that had never been seen before.

These climate changes will become more severe in the future. We humans can only try to slow down the speed through our efforts. However, it is foreseeable that the earth in the future will no longer be suitable for human survival, and it may become Like Venus.

Most paleontologists now believe that the sixth mass extinction of life on earth is occurring, this time caused by humans, starting at the end of the last Ice Age, about 12,000 years ago Years ago;

With the rise of agriculture, large-scale human civilization and the industrial revolution, human pollution of the environment, destruction of the natural environment, and occupation of biological habitats have led to a rapid acceleration of biological extinction. , the rate of species extinction on Earth is now 500-1,000 times higher than the normal background extinction rate.

Judging from the previous mass extinction events on the earth, the species that dominated the earth at that time were the first to suffer, so humans will bear the brunt of the sixth mass extinction.

Whether it is the current epidemic, new viruses that may appear in the future, or the ecological deterioration problems faced by mankind now, mankind cannot avoid or stop it. It can only slow down the speed of occurrence as much as possible. This will create more time for us to realize interstellar migration.

There will definitely be more troubles in the future than there are now, and they will occur more frequently. These are the results of human development. So we often say that science is a double-edged sword. We do not develop science. We will not be able to survive well;

But when we develop science, we will use science to transform nature and destroy nature. In the end, it is humans who suffer the consequences. We have no choice, we cannot sit still and wait for death, we cannot put all our eggs in one basket, we need to find another habitat.

This is what Hawking was worried about during his lifetime, and what he warned mankind about. He worried about the future of mankind countless times on different occasions, and warned mankind to find another habitat, because he knew Humanity will not last long on earth.

This is exactly what Elon Musk, the new world’s richest man, is doing every day. His biggest goal is to build a Mars base and send humans to Mars, because he also knows that the only way to do it is to go out. , only then can mankind have hope.
