Another theory for the extinction of species on Earth has emerged

The movement of animals causes the extinction of certain species

Humans are responsible for the extinction of species of animals and birds on Earth. It was they who were directly or indirectly responsible for the extinction of a number of living creatures on the planet.

According to Livescience, not long ago, the Wandering Pigeons (Ectopistes migratorius), which are more like clouds due to their number, were flying in the sky, flying from place to place. However, people began commercial hunting of these birds in the 19th century, and by 1914 they were completely extinct.

"Traveling pigeons are a prime example of how quickly and effectively humans can wipe out even the most common species," the article says.

Animals are also involved in species extinction. However, in this case, there is a condition - they must be moved to a habitat that is not typical for them. And here again, "the human factor comes into play."

"Some animals are capable of interspecific extermination if people place them in the wrong place, and they become invasive species that cause environmental or economic damage to their non-native environment. For example, Burmese pythons (Python bivittatus) from Asia eat everything that moves in the Everglades Nature Reserve in Florida (USA). According to the Florida Museum of Natural History, the local population of pythons began as pets that were released or escaped," the authors of the article cite an example.

As British biology professor Tim Blackburn told Livescience in an interview, the most typical example of an invasive species is the domestic cat.

"Cats have contributed to the extinction of dozens of bird species," he said.

Blackburn gave the example of the disappearance of the Stevens Island sparrow (Traversia lyalli) in New Zealand. He believes that the birds disappeared because of the cats brought there.

He also noted that, according to the American Bird Conservancy, cats are a direct cause of the death of a number of bird species in the United States and Canada.

"Humans are responsible for the movement of predatory cats and giant snakes across the planet. Anything they do after that will be our fault," Blackburn emphasized.

According to the professor, animals tend to naturally disperse in adjacent areas where species are generally similar and, accordingly, respond adequately to each other, so unequal clashes usually do not occur, unlike human-initiated relocation.

The scientist emphasized that he does not know of any examples of natural animal invasions when one species absorbed another to the point of complete extinction.

According to him, humans are clearly driving species to extinction through actions such as excessive hunting, environmental destruction, and the introduction of invasive species.

"The fact that the impacts are so dramatic is in itself almost compelling evidence that these processes are real and very different from what has happened before," Blackburn said.
