Humans ‘eating species to extinction’
Print Edition
SOME 300 wild mammal species in Asia, Africa and Latin America are being driven to extinction by humanity’s voracious appetite for bushmeat, a world-first assessment released yesterday concluded.
The species at risk range from rats to rhinoceros, and include docile, ant-eating pangolins as well as flesh-ripping big cats.
The findings, published in the journal Royal Society Open Science, are evidence of a “global crisis” for warm-blooded land animals, 15 top conservation scientists concluded.
“Terrestrial mammals are experiencing a massive collapse in their population sizes and geographical ranges around the world,” the study warned.
This decline, it said, was part of a larger trend known as a “mass extinction event,” only the sixth time in half a billion years that Earth’s species are dying out at more than 1,000 times the usual rate.
Besides eating them, humans are robbing mammals of their natural habitats through agriculture and urbanization, and decimating them through pollution, disease and climate change.
According to the Red List of endangered species produced by the International Union for the Conservation of Nature, a quarter of 4,556 land mammals assessed are on the road to annihilation.
For 301 of these threatened species, “hunting by humans” — mainly for food, but also as purported health and virility boosters, and trophies — is the main threat, according to the comprehensive review of scientific literature. The likelihood of extinction, the team found, depends on body size: the bigger the animals, the greater the danger.
“These species will continue to decline unless there is major global action to save them,” Bill Ripple, a professor at Oregon State University and lead author of the study, said.
