Is the sixth extinction coming? Scientists: In 1 billion years, humanity may face a major crisis
In the eyes of most people, the earth and the sun will always be in a stable stage, and long-term existence, but in fact, there is no immutable thing, even the earth and the sun can not do the same, every once in a while, the earth will have species changes, and the sun, life expectancy is about 10 billion years, every 1 billion years will change, its brightness will increase by about 10%, that is, after 1 billion years, the earth will lack a lot of liquid water, organisms may also become less, What about humans? Will 7 billion people still exist?
According to incomplete statistics, human beings have existed on the earth for millions of years, during which they have undergone various evolutions, and eventually developed into today's grand situation. However, the earth is not the stability of our imagination, has experienced 5 biological mass extinctions, there are rumors that the sixth species extinction or the future, not to mention, the situation in the past two years in various countries is not good, a variety of extreme weather attacks, but also accompanied by volcanic eruptions, earthquakes, tsunamis, etc., scientists are more urgent warnings, reminding human beings to remain vigilant, bluntly saying that a huge disaster is accelerating.
Although these are only speculations at present, but the earth frequently warns human beings, the global warming situation is getting worse, the rate of glacier melting is accelerating, it is difficult not to worry, if the ancient virus hidden under the glacier flows out, what will the earth look like? In addition, there is the uncertainty of the sun, from the current research results given by scientists, the sun has passed 5 billion years, life has gone halfway, and then 5 billion years, or will become a huge fireball, at that time, the liquid water on the earth or will not be able to survive, the organism will be less and less, perhaps less than 5 billion years, scientists expect that after 1 billion years, the earth will be affected by high temperatures, then, how should humans who have lost water resources survive?
In other words, in another 1 billion years, when the earth changes, what stage will human science and technology develop? In 1964, Kardashev proposed a hierarchical distinction, 10 years later human beings may reach the primary civilization, can master any resources on the earth, if it is a second-level civilization, it can travel freely to other planets, control the resources in the solar system, there is no need to worry about the risk of earth destruction, if it is a third-level civilization, it will expand to the galaxy.
As far as the current development of human beings is concerned, it is not yet up to the primary civilization, so is it possible to reach the top civilization in the universe after that? Throughout the history of human development, millions of years have developed to the present, perhaps, the future of human science and technology will have great progress, in a short period of time to reach the first level of civilization, to solve this crisis, as for the top civilization in the universe, this process is relatively long, we need to slowly explore. But our primary goal now is to protect the planet's ecology so that humanity can live forever.
