How people harm nature millions of years ago?

Millions of years ago there were no factories and cars, but still hurt nature

It's hard to realize, but in every moment of its existence, mankind is destroying nature. We cut down the forests, pollute the air with factories and cars, as well as daily throw away tons of plastic waste. There is therefore nothing surprising in the fact that the temperature of our planet rises gradually and raceplay glaciers, and inside the huge whales and fishing nets. It is noteworthy that the detrimental effect of man on nature and animals began not tens or even hundreds of years ago. People harm the environment more than a million years. But how is this possible if the ancient people had cars and they did not produce plastic waste?

According to the study, the results of which were published in the scientific publication , to harm nature and animals started by our ancestors. In the course of the study found in East Africa, fossils of Swedish scientists noticed that the numbers began to decline considerably after our ancestors grew a brain. According to biologist Daniel Silvestro, preying on the herbivorous animals, ancient people deprived of the food of predators, leading to their gradual destruction.

When man began to destroy nature?

According to the scientists, similar to modern humans primates appeared only about 200,000 years ago. But our ancestors like Australopithecus emerged earlier and lived much longer. Studying the fossilized remains of humans and animals, scientists have found that the number of predators decreased practically synchronously with how the ancient people developed brain. It turns out that the more skills mastered, the people, the better they were animals.

the Ancient people could leave some predators without food

The Researchers noted that the greatest environmental damage people have caused, when it mastered so-called kleptoparasitism. This term is commonly understood as a survival strategy when one animal takes food from other species. This behavior can be observed almost everywhere. For example, seagulls and monkeys sometimes like to steal human food, and even lions and hyenas often eat someone else's prey.

This is a very convenient and practically devoid of risk survival strategy, so the ancients are probably very willingly used it. Only now eating someone else's prey, they could doom them to certain death from hunger. How many carnivorous animals were destroyed during the existence of reasonable people is unknown. But surely there were so many.

With all this, scientists believe that the harm ancient people were just miserable in comparison with what damage to nature apply we are today. To understand the magnitude of the problem, it is enough to read our material on how much and how .
