Who are the natural enemies of mankind?

The natural enemies of human beings are viruses and natural disasters.

For example, in the 20th century, smallpox alone killed more than 300 million people, a staggering figure equivalent to more than three times the death toll of all wars that took place in that century; The Spanish flu outbreak of 1918 killed 34 million people and even affected the outcome of World War I.

From the development of primitive society to the present, human beings are constantly digging their own graves after countless wars, rapid economic development, etc., which are endlessly demanded from the earth, resource depletion, landform destruction, environmental pollution, disaster outbreaks, disease epidemics, etc.

Species profile

The oldest known fossil was formed in Ethiopia about 160,000 years ago. Homo sapiens in Europe appears to have replaced Neanderthals about 30,000 years ago. We don't know if this is a natural process.

The rest of the world is also gradually being occupied by Homo sapiens. They migrated to Asia and Australia at least at the same time as they appeared in Europe, but arrived in northeastern Asia much later.

The New World was the latest, not earlier than 10,000,000 years ago. Homo sapiens not only had new body structures, but also made more complex tools and kits, eventually developing Art Deco. In addition to the fossil record, there is growing detailed evidence of technological and social behavioural developments in later periods.

"Four evils".

The "four pests" refer to flies, mosquitoes, rats, and cockroaches. They all have one thing in common: they are extremely numerous. These four animals can never be counted by humans, and their distribution is almost worldwide.

Among them, mosquitoes are directly sucking human blood to transmit the bacteria and viruses they carry to humans, because of their large number, mosquitoes have become the world's most killing creatures, according to incomplete statistics, the number of people who die from mosquito-borne diseases exceeds 70,000 every year.

Humans have no natural predators

We are proud that humans are at the top of the planet's food chain.

If human beings have natural predators, there is a species in nature that specializes in preying on humans, and the energy obtained by this species is even less than that obtained by humans, and it is difficult to maintain the survival and reproduction of this species with such scarce energy, and the result is only extinction.

Therefore, theoretically, perhaps in the early days, there may indeed be a species in nature that specializes in preying on humans, that is, human natural enemies, but the energy provided by humans is far from allowing this species to survive, and the result is only extinction.

Early humans may have had natural predators, such as ferocious beasts, and it was difficult for early humans to defend against beasts by brute force alone. However, with the increase of human brain capacity, especially learning to use fire, making tools, etc., the combat effectiveness of human beings has gradually improved, and the natural enemies of human beings will gradually become extinct, and human beings have stood at the top of the food chain with their super intelligence.

Humans have no natural predators, and we are proud to be at the top of the planet's food chain. But nature never bows to any species, and human wisdom seems insignificant in the face of nature.

The concept of natural enemies was originally ** in one creature feeds on another creature, natural enemies are generally predators, what do you say can prey on humans, what should be considered human natural enemies, but because most humans live in cities, there are few opportunities to contact natural enemies, but if it is in the wild, it is different, for example, send a person to the North Pole, he is only equivalent to the snow goose in the link of the food chain in the Arctic, it can be said that many animals can kill people.
