If we leave the earth, will we humans be able to survive? Why?

It should be able to survive, but so far I haven't found a living environment similar to the earth! The universe is big and limitless, and the earth is just a drop in the ocean! After the continuous exploration of human beings, we will definitely find the corresponding living environment! Whether it's Jupiter.

Saturn, Venus, etc. are not suitable for human habitation! But in the near future, a planet suitable for human habitation will definitely be discovered.

We humans cannot survive without the earth, because there is no planet other than the earth that can be habited for the time being.

If it is to be suitable for living things, then the planet must meet the following points:

1. The atmosphere of the planet must have basic elements such as hydrogen and helium, which provide the basic conditions for the creation and survival of life.

2. The activity should be carried out continuously, so as to meet the conditions for the formation of the original atmosphere and water in 1!

3. Luck! If you can be in the safety of the asteroid belt, being hit by one or two may speed up the progress of evolution.

Of course, human beings do not have enough civilization, and even if there is such a planet, it can only be reached in the dust.

With the current level of technology, there is no way for us humans to survive outside of the earth, because there is no oxygen and no food in outer space**.

In the universe, there are many planets that resemble the Earth's environment, but they are too far away from us. If you can get there, you should be able to survive as well.

Organisms change to adapt to different environments, which means that humans adapt to the environment of the earth. If humanity leaves the planet, it will either change the environment or change itself.

1.Change the environment.

In fact, the Moon Village is this kind of concept, artificially building a small ecological circle on the moon to accommodate human survival.

In fact, it is much more difficult to leave the earth and build such an environment on another planet than to open up the wasteland. Some planets have extremely harsh environments. For example, Saturn's lightning storm is up to about 10 times a second, and the strong lightning storm compresses the structure of carbon in the atmosphere to produce fine diamonds.

There are also planets with strong acids, and some planets with perennial volcanic eruptions, so I won't list them all in this article. It is conceivably difficult for humans to build an ecosystem in these environments. It's much harder than turning a desert into an oasis on Earth.

2.Change yourself.

There are two types of this. The first is not getting rid of biological features. In other words, metabolism is still needed, and many conditions such as temperature, water, and food need to be met.

In this case, the only way to evolve is to change the DNA according to the environment. Through genes, we target a certain environment (such as Mars) and adapt humans to survive there.

The second is to get rid of living organisms. Now the cutting-edge biotechnology metal cell has subverted the human definition of life. Biologists have reservations, but the lab has proven that it is still unknown whether this inorganic life can be hereditary and evolutionary like organic life.

There is no air in space, and human beings need a lot of air to survive, and organisms will make changes to adapt to different environments, and human beings have long adapted to the environment of the earth and cannot change in a short time.

How long will humans survive on Earth? The scientist gave the answer, and it was unacceptable to read it!

Scientists in the field of astronomy and outer space research have two main views on whether human beings should leave the earth: one is that it is better for human beings not to leave the earth, but to stay on the earth to seek sustainable development, and should not extend their hands too much to outer space; The other is that human beings should leave their homeland on earth, actively explore outer space, look for traces of extraterrestrial civilizations, and plan for the further development of mankind. At present, the two views are at odds, the main reason is that the current level of science and technology is limited, and there are too many unknown areas in outer space, so scientists can only make conjectures and judgments based on their existing knowledge, which naturally arouses the thinking and reverie of the entire human community.

The famous physicist Stephen Hawking also expressed his opinion on this, he believes that human beings should not easily send signals into outer space, nor can they respond to various signals from outer space. Because he believes that there is a great possibility of a higher-level alien civilization, once he learns that there are abundant resources on the earth, he will inevitably come to the earth, and it will be a disaster for mankind at that time.

This idea is similar to the law of the dark forest in Liu Cixin's "Three-Body Problem", which states that if a certain cosmic civilization exposes its spatial coordinate position in the universe, then it will inevitably be hit by other higher civilizations, which will be a disaster. However, Hawking also proposed that human beings should find another home as soon as possible, believing that human beings' excessive exploitation of the earth's resources has disrupted a certain balance, and it is likely to lead to extinction due to some kind of disaster. Such a statement may sound creepy, but more scientists and people are optimistic.

To sum up, it can be seen that the existing scientific means cannot prove and ** the future of the earth, for more people, the earth is the home of mankind, is the mother of mankind. What human beings can do at present is to conduct in-depth scientific research to understand themselves, the earth, and the universe, and at the same time need to re-examine the relationship with the earth so that human beings can achieve better development.

Since the evolution of human beings, all our physiological functions are based on adapting to the earth's environment for evolution, whether it is our brain, respiratory system or sensory system, all of this, let us change ourselves, and human beings, especially the most adaptable to the environment and famous, so if human beings want to embark on the universe, they must completely change the direction of our evolution in the long cosmic journey, painfully change their genetic status.

In the process of depicting space travel, those pilots all had severe anxiety disorders, and many people began to have cosmic deep-sea claustrophobia, in the face of the blank universe, in the face of a dead and silent environment, normal earth human beings simply cannot adapt, human beings may need to go through more than ten generations to truly become a space species, but this process is really full of unknowns.

According to the scientists' cosmic modeling, we can know that in fact, the entire universe has been in a boiling state, whether it is a galaxy running at high speed, or a trend of stars every few seconds, there is a crisis everywhere in this environment, and the speed of this crisis is very fast, as long as any object steps into it, it is difficult to escape, in comparison, Our Earth and the solar system are just too safe.

Therefore, on the basis of this point, scientists believe that human beings should cherish the existing living environment, if they really want to go to the universe, maybe they will encounter more dangers, and even we will go to destruction, if it is more exaggerated, maybe we will meet other cosmic partners, but these partners have experienced the law of the dark forest, maybe they will also become our nightmares.

But because of the above two reasons, so scientists have been advocating at this stage, human beings should not be too obsessed with outer space, it is very likely that outer space is full of more dangers, the earth is our real safe harbor, I think what they said is still very reasonable, but we must also clearly understand that human beings are originally a race that faces difficulties, we have learned to achieve their own innovative breakthroughs in the difficult process, if we know that the external world is full of dangers and do not try it, Then human civilization is dead, so we can be fearful and reverent of the outside world, but we must not stop walking towards them.

One is that it is better for human beings not to leave the earth, but to stay on the earth to seek sustainable development, and should not stretch their hands too much into outer space; The other is that human beings should leave their homeland on earth, actively explore outer space, look for traces of extraterrestrial civilizations, and plan for the further development of mankind. At present, the two views are at odds, the main reason is that the current level of science and technology is limited, and there are too many unknown areas in outer space, so scientists can only make conjectures and judgments based on their existing knowledge, which naturally arouses the thinking and reverie of the entire human community.

Because in fact, scientists still have conservative thoughts, the earth is now the most habitable planet for human beings, and they don't know what will happen on alien planets, so scientists say it's best not to leave, and they don't say they won't leave here, all of which still need to wait for detailed data testing before making a judgment.

Because the earth is currently the most suitable planet for human habitation, other planets more or less do not meet the conditions for human survival, for example, the research Mars has detected traces of water, but there is no protection of human atmosphere, there is no air, unsuitable for human habitation, if you need to artificially create these conditions, it still needs to make great efforts.

1. Human destruction of the earth is mainly manifested in two aspects: ecological destruction and environmental pollution.

2. Cases: (1) Ecological destruction: the Amazon rainforest has been cut down on a large scale, affecting global climate change; Soil erosion and salinization of the land.

2) Environmental pollution: smog in China; water pollution in Kazakhstan caused by oil spills in coastal areas; Garbage siege incident.

3. Knowledge expansion: Ecological damage refers to the phenomenon that the natural ecological environment such as forests and grasslands is destroyed by the irrational development and utilization of human beings, thereby deteriorating the living conditions of humans, animals and plants. Such as:

Soil erosion, land desertification, soil salinization, loss of biodiversity, etc.

4. Environmental pollution refers to the behavior of natural or man-made destruction, adding a certain substance to the environment and exceeding the self-purification ability of the environment. (Or due to human factors, the environment is polluted by harmful substances, so that the growth and reproduction of organisms and the normal life of human beings are adversely affected.) The phenomenon of changing the composition or state of the environment due to human factors, and the decline of environmental quality, thereby disturbing and destroying the normal production and living conditions of the ecosystem and human beings.
