Man accelerated species extinction rate a thousandfold, study says


Research was published in the print edition of the journal Science. Despite the alarm, technology gives hope to preserve biodiversity.

A new study published this Friday (May 30) in the print edition of the journal Science states that human action has accelerated the rate of extinction of plant and animal species on the planet by 1,000 times compared to the natural rate. .

Data from biologist Stuart Pimm of Duke University in the United States indicate that before humans, the rate of extinction was one species every 10 million a year. These numbers are currently 100 per 1,000 per year.

Despite alarming numbers, the researcher says he is optimistic that new technologies allow environmentalists to step up efforts to maintain biodiversity.

Among them is the creation of a map, developed by scientist Clinton Jenkins of the Institute for Ecological Research, located in Brazil, showing where the most vulnerable species live.

The method helps to set conservation priorities for these sites and thus prevent the disappearance of animals or plants.

Historically, the earth has experienced five major extinctions, which annihilated more than half of the planet's life.

There is currently a debate among scientists who wonder whether humanity will be the cause of the next massive destruction of species.

However, it is already in the “guilt account” of the human being the disappearance of the bird Dodo (Raphus cucullatus) of the Tasmanian wolf (Thylacinus cynocephalus) and the Falkland Wolf (Dusicyon australis).
