But how will it be Earth, if man there never was?

Some scientists describe Earth which is ornate Forest native wilderness with species animal abundant.

“I think, Earth will become a much more vegetated place with riches animal large in size spread over all continents except Antarctica, “Trevor Worthy, a paleontologist and professor at Flinders University in Australia, told Live Science.

A world without modern humans might also mean that our extinct human relatives, such as the Neanderthals, would still exist.

And they, no doubt, will change the landscape too.

Humans have shaped the world at the expense of many species, from the dodo (Raphus cucullatus) to the Thylacine (Thylacinus cynocephalus).

They became extinct due to activities such as hunting and habitat destruction.

The rate of extinction on Earth is currently more than 100 times.

This natural decline due to human presence suggests that Earth would be a much wilder place without humans.

Along with the existence of humans, several giant animals began to become extinct, including the moa.

This group of ostrich-like birds has a height of 3.6 meters, they are

evolved in New Zealand over millions of years.

In the 200 years since the arrival of humans 750 years ago, all nine moa species have disappeared, along with at least 25 other vertebrate species, including Haast’s giant eagle (Hieraaetus moorei) that hunted moa, according to Worthy.

Soren Faurby, senior lecturer in zoology at the University of Gothenburg in Sweden, believes that humans played a key role in the disappearance of many large mammals thousands of years ago.

He led a 2015 study, published in the journal Diversity and Distributions, which showed that, without humans, Earth would largely resemble the modern Serengeti, an African ecosystem teeming with life.

For example, instead of the African lion (Panthera leo), there would still be the cave lion (Panthera spelaea), a slightly larger species that lived in Europe until about 12,000 years ago.

Meanwhile, America will be home to relatives of elephants and large bears, along with unique species, such as a car-sized armadillo relative called Glyptodon and the giant ground sloth, according to Faurby.

Large animals, such as elephants, are known as megafauna.

During the last Pleistocene ice age, (2.6 million to 11,700 years ago), the world was rich in megafauna, but most of it died out when the ice age ended, or in the thousands of years since.

For the past century, scientists have debated whether climate change is natural or activity man, like overhunting, is the main cause of the decline in numbers animal this big.

A 2021 study published in the journal Nature concluded that climate change ultimately wiped out the woolly mammoth (Mammuthus primigenius) and megafauna others living in the Arctic who survived the late Pleistocene, because the warming climate made it too wet for the vegetation they ate to survive.

However, man indeed hunting mammoths.
