Do you know what the world would be like if there were no humans on Earth?
Since human beings appeared on the earth, they have gradually built a complete biological chain and ecosystem on the earth, and created a civilized world. It can be clearly seen that almost everything on the earth comes from human beings. Hands and wisdom, the high-rise buildings and traffic in front of us, if not for human beings, these places are just flat ground. It can be seen how important the people on earth are, but if the 7 billion people on the earth suddenly disappeared, What significant changes will the earth have? What will happen to the earth in the next 100 years, hundreds of years and thousands of years? Experience what? You must be very curious too!
Experts have given guessed answers, but many people don't believe it, maybe not because they don't believe it, but because they can't accept that a civilized world created by human beings in millions of years should only take a few thousand years. Completely disappeared from the earth, even some substances that have existed for an extremely long time only need tens of thousands of years to disappear forever on the earth, and the traces of human beings seem to have been wiped out directly, which is why scientists have been speculating. Before the advent of humans, there were probably many civilizations on the earth, but the time interval between each civilization is likely to be hundreds of thousands or even tens of millions of years, so that with the current level of technology, it is impossible to The traces of their existence have been found, and human beings are likely to become one of the civilizations that descendant civilizations once wanted to find but could not find!
In the days and tens of days that human beings have just disappeared, some automated machines used for lighting on the earth will be in emergency use for about a week, but after the energy and fuel of some nuclear power plants are used up, the earth will be at night. It may fall into darkness, then in about two or three years, many high-rise buildings on the earth will rupture due to the lack of some functional devices for a long time, and will slowly collapse. , In about 100 to 200 years, the vegetation on the earth will grow wildly, and the roads on the earth will be completely covered by weeds and jungles. After about 1000 years, human beings will leave Many chemicals on the earth will gradually disintegrate!
The most important thing is that after 5,000 to 10,000 years, human beings are likely to disappear completely. I wonder what everyone thinks of this?
