Humans destroyed 83% of all wild mammals, study finds

Imagine all animals on Earth: lions and giraffes, monkeys, penguins and bears. All of these exist, of course, but you are much more likely to find cows, chickens, cows and more cows.

This is how Ron Milo, a biologist at the Weizmann Institute of Sciences in Israel, decomposed a new global study for The Guardian. Work a census of life on Earth, found that 83% of all wild mammals disappeared in the midst of the rise of human civilization.

With more humans came the demand for more livestock, think of pigs and cattle, which now accounts for 60% of all mammals, as measured by biombad. the study found. And poultry now make up 70% of all birds on Earth.

Only 4% of all mammals live in the wild.

The study, which highlights the "radical ecological effects" of humanity, published this week in the Proceedings of the National Academy of Sciences.

While humanity grew for a short time through agriculture, livestock and the Industrial Revolution, the authors point out that humans now represent a relatively miserable 0.01% of all life.

But that speck of humanity has a huge impact: the intense hunting of whales helped to decimate 80% of all marine animals, and half of all plants on Earth were lost.

"I hope people take this (work) as part of their global vision of how to consume," said Milo, a study author, The Guardian . Now eat less meat, he said.

Researchers extracted hundreds of studies from the first badysis of their kind, according to the newspaper, using data from satellite scans and gene sequencing to calculate biombad on Earth. [19659002] Read more about the study in The Guardian .
