Is mankind really going extinct?

It is undeniable that some scientists have done a lot of research work, which proves that human extinction is possible.

Everything will be destroyed one day, nothing is eternal, and so will our earth. According to estimates, our earth has been born for 4.6 billion years, and the universe has been born for almost 654.38+038 billion years, and everything will eventually end.

Since there is a birth, there will be an end, just like the day when we humans are born and face death, but this is only a process in the middle.

Four ways of human destruction

First, asteroids hit the earth.

My earth often meets many uninvited guests, because there are many asteroids and meteorites in space, and these meteorites often visit the earth. The Tunguska Big Bang may have been caused by meteorites or asteroids.

In 2.5 billion years, the sun will devour the earth.

According to scientists' estimation, after about 5 billion years, the hydrogen in the sun will be exhausted, and the inside will collapse and expand into a red giant. At that time, the volume will be dozens of times that of now. Such a huge red giant will devour all the planets in the solar system. Since the earth is going to be destroyed, mankind is going to be destroyed. If human beings can develop into interstellar immigrants, they may be able to continue the spark, provided that there must be a suitable planet.

Three, the deterioration of the earth's environment, nuclear radiation caused by human beings can not survive.

Compared with the past decades, our earth has been seriously polluted. Automobile exhaust from various factories has caused the greenhouse effect. The Fukushima nuclear power plant in Japan also discharges sewage into the Pacific Ocean. It is said that it will be discharged for another 30 years, and the marine ecosystem will definitely be affected in the future, which will also endanger human health and safety.

Fourth, resources are exhausted and the natural environment is deteriorating.

The progress of human science and technology cannot be separated from the exploitation of the earth's resources, which are limited and will be exhausted one day. In just a few hundred years, human beings have consumed a lot of resources, the vegetation of the earth has also been destroyed, the environment has begun to deteriorate, and the global climate has begun to warm up. It may not be obvious now, but after tens of thousands of years, the earth is probably no longer suitable for human survival.
