Five times in the history of 450 million years of Earth, a huge percentage of the species in the planet has been wiped out in mass extinctions, and now it’s happening again, claims a new study report.

Earth’s 6th mass extinction is underway with Humans as the cause

Earth’s 6th mass extinction is underway with Humans as the cause

Bringing the most frightening nightmare or the fact that people read all day, researchers and scientists at Stanford University, report that the new evidence suggest the Earth to be on the brink of its sixth mass extinction, like the mass extinction that wiped out the Dinosaurs, that is the first days of a great and much sneakier type of extinction are underway. And the ones to be blamed for this planet to be on the verge of another great biological extinction, is not the usual cause – collisions with giant meteors, but the humans through global climate disruption and habitat destruction.

According to the report, in the last 5 centuries around 322 species in the planet have gone extinct, while there has been a decline in abundance in the remaining land-dwelling species of vertebrates, by around 25 percent. In case of invertebrates, the situation is likely a dire with over 45 percent decline in all the monitored species, which in turn points out that the Earth to be in the early days of another mass extinction event.

Lead author Rodolfo Dirzo, a biology professor at Stanford University, citing actions like habitat destruction and overexploitation of resources to be harmful human activities resulting in the extinction of species, said “We tend to think about extinction as loss of a species from the face of Earth, and that’s very important, but there’s a loss of critical ecosystem functioning in which animals play a central role that we need to pay attention to as well.”

Dirzo continued “Ironically, we have long considered that defaunation is a cryptic phenomenon, but I think we will end up with a situation that is non-cryptic because of the increasingly obvious consequences to the planet and to human wellbeing.”

Pointing to potential trickle down effects, “Where human density is high, you get high rates of [animal decline], high incidence of rodents, and thus high levels of pathogens, which increases the risks of disease transmission,” Dirzo said in the statement, adding, “It can be a vicious circle.”

This is not the first instance for a report to point to sixth mass extinction in Earth as back in May this year, Biologists from Duke University, citing the difference between the past and present rates of extinction, reported that the planet is on the verge of the sixth mass-extinction event, as the animal life as well as plant life are going extinct 1,000 times faster, at the present rates compared to the rates before the arrival of human populations.
