Have you ever wondered what is the natural enemy of human beings?

I have thought that if one day human beings are extinct on the earth, our natural enemies must be ourselves and aliens.

None of the existing creatures on earth can destroy all mankind on a large scale. So I can't think of any specific living creatures that can destroy the earth for the time being. We make our life better and better through the power of science and technology, and more and more rich human civilization is developing at a high speed.

However, in the development of the ancient universe, we didn't have a long time to thrive on this blue planet. Therefore, short-term stable development does not mean that we may be wiped out by natural enemies.

Marxist philosophy tells us that the development process of a thing must have its origin and extinction. Nowadays, the living environment of human beings has been greatly destroyed. The contradiction between the sustainable development of science and technology and the economic level, the constantly destroyed natural environment and the scarcer resources is constantly prominent.

Many natural scientists appeal that if we humans don't face up to environmental problems, the earth will become even more uninhabitable. One day we will be destroyed by the deterioration of our own environment and the war of grabbing resources and energy.

Even the foreseeable genetic mutation effect of nuclear pollution on natural organisms can lead to this result. So the natural enemy of human beings must be themselves. Everything begins with itself.

The internal reason is oneself. Then, if external causes can make mankind perish quickly, then our natural enemies are malicious and more advanced alien creatures and civilizations.

Under the absolutely advanced civilization, people on earth will be smashed into slag in seconds. This is the end of the world in many TV dramas.
