? But the damage caused by nuclear war may be more extensive, but it is still not enough to subvert the foundation of the whole earth's ecology, that is, the most basic microbial ecology of the earth. Microorganisms have a very efficient reproduction rate, simple genetic material and cell structure, a large number, and great survival toughness. Gene mutation caused by nuclear radiation may also accelerate the evolution of these microorganisms. Perhaps in a very short time, microorganisms can evolve physiological characteristics related to the consequences of nuclear radiation. Even if all the higher organisms on the earth are extinct, these microorganisms can still create another completely different ecology with rapid evolution.
For example, plants and some microorganisms may be more adaptable to the environment than heterotrophic microorganisms, and the top of heterotrophic microorganisms is human beings. Dependence on other creatures is the fatal wound of human beings.
If nuclear war only annihilates human beings (usually the top species in the ecological chain are more fragile) and does not harm the breeding base of other species, then nature will replace human beings more quickly. This situation is obvious in Chernobyl.
Chernobyl incident
The Chernobyl nuclear accident seems to be an accidental experiment of human regional disappearance. After people evacuated from Chernobyl, various wild animals took over the area. Although radiation has brought some side effects to the health of wild animals and plants, the reproduction of these animals continues, and those who can survive are lucky. After a small setback, the whole ecological chain is still extremely prosperous. Although human beings will feel pity for those animals with radiation variation and regret the nuclear leakage, in fact, nature doesn't care about these-
Natural disasters have never been a tragedy of life on earth (only humans think it is a tragedy). The five extinctions in the history of the earth are all nodes that rejuvenate the earth, such as the biggest extinction event in the history at the turn of Permian and Triassic, the extinction of 70% terrestrial vertebrates and 96% marine life, and the only event that caused a large number of extinctions of insects. It is estimated that 57% families and 83% genera have disappeared. In this way, insects will not be severely hit by ordinary extinction events-because they are small in size, large in number and fast in reproduction.
Human tragedy is not necessarily a natural tragedy.
The appearance of human beings is just an accidental event in nature, so even if human beings "don't do it, they won't die" and destroy themselves, it is just like an accidental event in nature. Species have been extinct at any time in the history of the earth, which may be one of the reasons, such as extinction due to nuclear war. God should not make a fuss. At the end of Permian, he wiped out the theropod reptiles that occupied the top of the food chain, supporting the upper position of dinosaurs, so dinosaurs flourished more than 654.38 billion years ago from Jurassic to Cretaceous. At the end of Cretaceous, he destroyed dinosaurs and fed mammals, which led to the prosperity of mankind in recent tens of thousands of years. The next time he accidentally exterminates human beings, the plot will probably be the same-new biological forms will replace human beings and walk on the earth.
abstract
After human extinction, it must be replaced by other creatures;
Human tragedy is not necessarily a natural tragedy;
Ecology is based on autotrophic microorganisms and organisms. As long as these creatures are not extinct, the earth will be full of vitality.
