What are the natural enemies of mankind?

The natural enemy of human beings is human beings themselves. Since the development of primitive society, countless wars and high-speed economic development have endlessly demanded from the earth, such as resource depletion, landscape destruction, environmental pollution, disaster outbreak, disease epidemic and so on. And humans are constantly digging their own graves. The natural enemy of mankind is natural disaster.

The history of mankind has always been a history of fighting infectious diseases, and the harm of infectious diseases to human beings can be said to be incalculable. For example, in the past 20 centuries, smallpox alone claimed more than 300 million lives, which was equivalent to more than three times the death toll of all wars in that century; 19 18 The Spanish flu outbreak killed 34 million people and even affected the war situation in the First World War.

Natural enemies

People are primates. Primates love rainforests, mainly living in trees, avoiding large predators, and natural enemies are less harmful. Five million years ago, the ancestors of early apes entered the grassland and suddenly met many predators, such as lions, leopards and crocodiles, which may be the natural enemies of early humans.

Early humans exercised and learned to use tools, weapons, etc. The emergence of these early cultures has largely protected the threat of nature to mankind. Humans further developed their culture, and weapons such as stone axes appeared (2 million years ago), and they knew how to use fire (10 million years ago). Culture separates human beings from nature. After the agricultural society (10,000 years ago), human beings completely broke away from the biological food chain.

Nowadays, we live in an artificial environment completely wrapped by culture. Looking around, computers, desks, clothes, cars, pets, cats and dogs, concrete floors, road green belts and artificial forests in parks all belong to natural ecosystems.
