Mystery of interstellar migration

The whole year of 2020 will make each of us form a very good habit, that is, wearing a mask all the time when going out, which can not only keep warm and isolate the dust in the air, but more importantly, prevent the invasion of droplets carrying viruses.

No matter where you go, you need to show your health code when you take a bus or go shopping. An epidemic has completely changed our living habits. Fortunately, when the virus raged around the world, our lives were relatively normal and were not greatly affected.

This is due to the unsung hero who rushed to the front line for selfless dedication, and also benefited from the active participation and consciousness of every ordinary citizen.

Just when everyone was relaxing and preparing to go home for the Spring Festival, the virus began to rebound again, which made us feel nervous again last year.

Just now my girlfriend asked, what should I do if I can't go back this year? It has been a whole year. When will this end? I told her that 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 our human troubles have just begun in the future.

She explained that she must go home early for the Spring Festival next year. This suddenly makes me feel a little endless.

Because we humans are a whole in the face of the virus, as long as there is one virus carrier in the world, the epidemic will not end, just like when humans eliminated the smallpox virus, 1975 and 1977 the last two patients who naturally carried smallpox were cured;

And after the whole people were vaccinated with smallpox vaccine, mankind declared victory over smallpox in 1980. This is the first time that mankind has won the battle against the virus, but the process of defeating smallpox lasted for 3000 years, and human beings paid hundreds of millions of lives.

Therefore, in order to get rid of this virus disaster completely, the only way now is to realize the global comprehensive vaccination work and completely eliminate the living space of the virus, so as to win this battle completely.

Then look at the current international situation. What do you think will happen at 20 1 1? It is entirely possible to estimate that today will be another year, and we can't relax.

But in the future, mankind will encounter more troubles, which are inevitable for the normal development of mankind, and they are disastrous and even affect the survival of mankind.

1. This virus will accompany us for a long time. Always be vigilant and pay attention to protection in your life.

The reason has been said above, only by thoroughly curing the last virus carrier and vaccinating the full name vaccine can victory be declared. It can't be done in a short time anyway.

2. Humans will encounter the same problems in the future;

Although their life forms are not advanced, microorganisms are the oldest, most tenacious, richest and most widely distributed life on earth. Moreover, their mutation and innovation speed is very fast;

Therefore, from these perspectives, they are more like the masters of the earth. Because their lifestyle is mainly boarding, as long as we humans exist, as long as these microorganisms exist, we may face the risk of being invaded by new viruses again.

Throughout history, these microorganisms have brought more casualties to human beings than any disaster or war, and they have even shaped the development trend of human society. Therefore, we often say that the history of human development is a history of struggle with microorganisms.

This kind of struggle will not decrease in the future, and it will always be a human problem. In addition to the threat of microorganisms, there is also the problem of human development.

3. Environmental pollution and greenhouse effect

Air pollution, water pollution and white pollution have now become the biggest headache for human development. In a big city, if you stand high, you will see a layer of gray smog under the blue sky hanging over the whole city.

These smog are very small particles, which are difficult to disperse. They will enter people's lungs and even the circulatory system and cells in the body through breathing. Humans have to breathe all the time, which will be fatal to us.

Last year, a paper showed that carbon particles, industrial emissions and metal particles in automobile exhaust have all entered the human placenta, all of which we inhaled from the lungs.

Water resources, like the atmosphere, are the foundation of the earth's ecology. What kind of creature can get rid of the need for water? If there is something wrong with the water itself, the life on the earth can't survive naturally.

White pollution has also intensified in recent years. Scientists have found that plastic waste thrown away by human beings is not only difficult to decompose naturally, but more dangerously, these white plastics will release micron-sized particles into organisms. As a member of the biological chain, human beings are naturally inevitable.

A paper in 20 19 revealed that plastic particles were found in human feces. Last year, a paper showed that plastic particles also enter the human placenta like carbon particles and metal particles.

Now we know why in recent decades, we would rather lose economic benefits than Jinshan Yinshan, but also keep green mountains and green hills, because it is urgent to control environmental pollution.

Human carbon emissions not only cause air pollution, but also bring unimaginable greenhouse effect, resulting in a global temperature increase of 65438 0.5 degrees Celsius compared with that before the industrial age.

At present, the lowest temperature in the Arctic Circle -7 1 degree Celsius no longer exists, and now the lowest temperature is -50 degrees Celsius, which leads to the melting of a large number of glaciers and permafrost, and the colors of the land and rocks in the Arctic, even green, reveal many islands that have never been seen before.

These climate changes will intensify in the future, and we humans can only try our best to slow down this speed, but it is foreseeable that the future earth will no longer be suitable for human survival and may become like Venus.

At present, most paleontologists believe that the sixth mass extinction on the earth is happening, this time caused by human beings, which began at the end of the last ice age, about 6.5438+0.2 million years ago;

With the rise of agriculture, large-scale human civilization and industrial revolution, human pollution to the environment, destruction of the natural environment and occupation of biological habitats, the speed of biological extinction has accelerated dramatically. At present, the extinction rate of species on the earth is 500- 1000 times that of the normal background.

Judging from the past mass extinctions on the earth, the species that ruled the earth at that time were the first to suffer, so human beings bore the brunt of the sixth mass extinction.

No matter the current epidemic situation, the new virus that may appear in the future, or the ecological deterioration that human beings are facing now, human beings cannot avoid and stop it. They can only slow down the speed as much as possible and create more time for us to realize interstellar migration as much as possible.

There will definitely be more troubles in the future than now, and the frequency will be higher. These are the results of human development, so we often say that science is a double-edged sword, and we can't survive well without developing science.

However, when we develop science, we use science to transform and destroy nature, and the ultimate victim is human beings themselves. We have no choice. We can't just sit back and wait. We can't put all our eggs in one basket. We need to find another habitat.

This is exactly what Hawking was worried about before his death, and it is also a warning to mankind. He worried about the future of mankind countless times and warned mankind to find another habitat, because he knew that mankind would not live long on the earth.

This is exactly what elon musk, the world's new richest man, is doing every day. His biggest goal is to build a Mars base and send human beings to Mars, because he also knows that only by going out can human beings have hope.
