A landmark study by an international group of scientists has concluded that planet Earth is on the brink of a mass extinction event comparable in scale to the one that wiped out the dinosaurs 65 million years ago.
The researchers found that extinction rates are currently 1000 times higher than normal due to deforestation, changes in climate, and the depletion of ocean fisheries.
Duke University biologist and conversation expert Stuart Pimm says that “time is running out” to avert the threat of mass extinction.
If the crisis is to be avoided, humans need to make large scale changes immediately, Pimm says.
“When you look at the range of unsustainable things we are doing to the planet — changing the atmosphere…massively depleting fisheries, driving species to extinction — we realise we have a decade or two,” Pimm warned. “If we keep on doing what we are doing by the end of the century our planet will really be a pretty horrendous place.”
The study compared historical extinction rates with contemporary data collected from around the world.
“We can compare
