It’s natural, like metastatic cancer. If a society consumes and kills and reproduces as quickly as possible, it will outcompete a society with longer-term vision.
The world desperately needs a rational, new economic system designed against this root cause.
According to Robin McKie
Tigers, coral reefs and all the marine life they support, amphibians such as the golden frog of Panama, orang-utans, sharks, mountain gorillas, the marine iguanas of the Galápagos, albatrosses, chimpanzees and thousands of other creatures now face obliteration: hunted, rendered homeless, and poisoned by humans.
More to the point, this predation has been going on, not for hundreds of years, but for tens of thousands of years.
Whenever Homo sapiens has moved into new territory, this has been followed quickly by the disappearance of most large land mammals, palaeontologists have found. For example, the Clovis people, ancient hunters armed with fearsome stone-tipped spears, arrived in North America 12,000 years ago.
A total of 75 species, including woolly mammoths, mastodons, four-horned antelopes and lumbering sloths the size of giraffes were killed off almost immediately. A thousand years later, the slaughter continued in South America when humans arrived there.
The glyptodon (a giant armadillo-like animal), several species of rodent and various llama-like animals were wiped out. And a similar bloodbath occurred in Australia with the arrival of the first members of Homo sapiens.
