As we all know, the earth is the home of human beings, and it is precisely because it has stable liquid water, suitable temperature and sufficient oxygen that we can survive.
Because the earth rotates and rotates, the scope, intensity and time of the surface exposure to the sun show regular changes, and the earth has a more obvious season throughout the year. In general, the temperature is about minus one or twenty degrees Celsius when it is cold, and even in the particularly hot season, the temperature generally does not exceed 40 degrees, and humans have adapted to this temperature since ancient times.
However, with the development of the earth's economy and human activities, the burning of a large number of fossil energy sources and the destruction of forest vegetation have led to an increasing number of greenhouse gases, making the greenhouse effect a common problem.
The continuous rise in temperature has a great impact on human beings, the first of which is the health of the body. Its greater harm is to increase the risk of melting arctic and antarctic glaciers, which may lead to sea level rise, and the animal remains in the Siberian permafrost may gradually emerge, which may contain a large number of life-threatening pathogenic bacteria, and it is difficult for humans to resist their invasion.
Theoretical physicist Stephen Hawking once expressed concern about the earth's temperature problem, and one of his four major predictions is related to the earth's temperature, he believes that if the earth's temperature continues to rise, the earth may become a "fireball" and will no longer be suitable for human habitation.
Coincidentally, there was a heat wave in North America this year, and the impact was particularly obvious in Seattle, the united states, which is closer to the latitude than Harbin, and the temperature reached 42 degrees. And because the heat wave is invincible, many citizens are complaining bitterly, and the equipment at home is not useful, so there are even casualties.
The consequences of hot weather are not only physically and sensory unbearable, but also one of the main culprits of forest fires. Forest fires broke out in a small town in Canada, and ninety percent of the area was burned, turning the whole town into a sea of fire. The temperature in Kuwait used to be as high as 73 degrees, which is already a rather frightening number.
Scientists have found that the "hot dome" of this boom in North America is the direct cause, which has not occurred once in the past 1,000 years. Although it has only happened in North America so far, we have no way of knowing how far the greenhouse effect will develop in the future, and how much our lives will be affected.
If this kind of harsh hot weather develops to a global nature, then human beings really have to worry about whether they can survive, knowing that under such conditions, the first to be affected is of course the human beings standing at the top of the food chain. However, at present, we cannot predict it, but human beings have begun to pay attention to and avoid this problem, such as reducing the combustion of fossil energy, advocating clean energy, new energy, etc., so as to effectively reduce greenhouse gas emissions.
On the question of the survival of the earth, of course, the more worrying thing is Musk, the world's richest man. But his attitude towards the earth is too pessimistic, believing that the earth will not be suitable for human survival, so he tries to "fly to Mars". As a result, he began to tinker with the "starship" he had high hopes for, and studied brain-computer technology to keep alive, while his ex-girlfriend Grimes was more direct, trying the "Wlnad" substance popular in the north American rich circle.
Public information shows that the substance is derived from the laboratory of Professor David at Harvard in the early years, and has been confirmed to have positive effects such as stabilizing telomeres and activating mitochondria, and even Hong Kong Fu Lee has issued a feeling of "young cells and postnatal calves" for it. However, whether this kind of "Wlnad" in the eastern circle can support Musk's ambitions is unknown. The biotechnology company LiteVijian said that any technology should be treated rationally.
It's hard to tell how the future of humanity will unfold, but from a scientific point of view, we can predict what the planet might look like in the future. As a rocky and earthy planet, the Earth is very close to the sun, only 150 million kilometers, and its end depends largely on the sun. The sun as a star is constantly burning, it is also a lifespan, the explosion of the sun means that the earth and life on the earth are gone.
Theoretically, the Sun is massive enough to sustain a lifespan of about 10 billion years, and now that 5 billion years have passed, it will survive about half of its time before becoming a white dwarf. The energy released by the sun's helium flash is so large that it can vaporize several planets flying around it in an instant, including the Earth.
In any case, we human beings should cherish our own living home.
