The earth we live on has a history of 4.6 billion years. The earth has experienced a long period of development, billions of years of evolution, after the mass extinction, ushered in the human beings with intelligent life.
The earth gives birth to human beings, provides a good living environment for human beings, and makes human beings continue. After the earth has experienced so much evolution, the birth of human is not easy, but in the process of human development, it has caused many irreversible damage to the earth.
After the birth of mankind, today, after hundreds of years of development, we have entered the era of science and technology. Human beings began to explore the mysteries of all things in the world, studying the mysteries of biology and the universe. It’s an endless road. I don’t know how long this exploration tour will last? How long can humans survive on earth?
As we all know, it is very difficult to survive forever on earth. In the long years that the earth has experienced, countless kinds of creatures have been born. Unfortunately, they do not exist on the earth forever. In the end, they are all buried in the breath of life by nature. Even the giant dinosaur, which has dominated the earth for 160 million years, was destroyed by asteroid collision.
Human beings live on the earth. Although advanced technology has been used to maintain life, human beings are too dependent on the earth’s resources. Continuous mining, bit by bit damage the earth, leading to the earth’s resources become increasingly scarce.
If we continue to develop in this way, the earth’s climate will be more and more bad, and the ecological environment will gradually be full of pollution and haze. In the future, the earth environment is likely to threaten the survival of life, and will no longer be suitable for human survival. Scientists predict that human beings are destroying themselves and will destroy themselves when the sixth mass extinction comes.
In addition to these, our sun has entered the middle and old age stage, and the function of internal coordination system has begun to decline. It is understood that the sun, as a yellow dwarf, will have a life span of 5 billion years. According to the monitoring results of scientists, sunspots are no longer as active as before.
As we all know, sunspots are very important to the sun. Because of sunspots, the sun can absorb more energy. The decrease or inactivity of sunspots means that the internal environment of the sun changes, which will directly affect the survival of the earth.
Today’s solar environment is not as stable as before, and the earth’s environment has also suffered great changes. The recurrence of extreme climate has seriously threatened the safety of human life.
Therefore, some scientists predict that the earth is coming to an end, which also means that human civilization is about to collapse. So in order to prevent this day, scientists have also implemented a lot of protection measures to constantly protect the earth’s environment.
At the same time, scientists are still looking for the “second earth”, hoping that human beings can realize the plan of migrating to the planet in the future.
We should not be too pessimistic because of the deterioration of the earth’s environment. After continuous exploration, scientists have found many planets similar to the earth. Scientists have found the existence of water resources necessary for human beings on Mars, Europa and other planets.
Water resource is an indispensable part of life. If human beings want to survive, water resource is a necessary condition. However, Mars and Europa still lack other basic conditions, so they are unable to meet the needs of human survival.
Stephanie Olson, a professor of geophysics at the University of Chicago in the United States, said that if we want to find a planet that can meet the needs of human life, we need to focus on ocean level.
Because as long as the planet has the ocean, it will be possible to meet the living conditions of life. So if the planet has oceans, it means that there might be life on the planet.
However, just because there are water resources does not necessarily mean there will be life. We also need to have the atmosphere and other factors, otherwise life can not survive on other planets.
So far, scientists have found many livable planets, and these planets have water resources, some of which may even be more suitable for human survival than the earth. Therefore, we should face the future with good expectations. As long as human science and technology are strong enough, then the plan of livable planet can be realized!
