New study warns world is facing sixth great extinction

May 2014 ECOLOGY – Species of plants and animals are becoming extinct at least 1,000 times faster than they did before humans arrived on the scene, and the world is on the brink of a sixth great extinction, a new study says. The study looks at past and present rates of extinction and finds a lower rate in the past than scientists had thought. Species are now disappearing from Earth about 10 times faster than biologists had believed, said the study’s lead author, biologist Stuart Pimm of Duke University. “We are on the verge of the sixth extinction,” Pimm said from research at the Dry Tortugas. “Whether we avoid it or not will depend on our actions.” The work, published Thursday by the journal Science, was hailed as a landmark study by outside experts. Pimm’s study focused on the rate, not the number, of species disappearing from Earth. It calculated a “death rate” of how many species become extinct each year out of 1 million species.
In 1995, Pimm found that the pre-human rate of extinctions on Earth was about 1. But taking into account new research, Pimm and his colleagues refined that background rate to about 0.1. Now, that death rate is about 100 to 1,000, Pimm said. Numerous factors are combining to make species disappear much faster than before, said Pimm and co-author Clinton Jenkins of the Institute of Ecological Research in Brazil. But the No. 1 issue is habitat loss. Species are finding no place to live as more places are built up and altered by humans. Add to that invasive species crowding out native species, climate change affecting where species can survive and overfishing, Pimm said. The buffy-tufted-ear marmoset is a good example, Jenkins said. Its habitat has shrunk because of development in Brazil, and a competing marmoset has taken over where it lives. Now it’s on the international vulnerable list.
The oceanic white-tip shark used to be one of the most abundant predators on Earth, but they have been hunted so much they are now rarely seen, said Dalhousie University marine biologist Boris Worm, who wasn’t part of the study but praised it. “If we don’t do anything, this will go the way of the dinosaurs.” Five times, a vast majority of the world’s life has disappeared in what have been called mass extinctions, often associated with giant meteor strikes. About 66 million years ago, one such extinction killed off the dinosaurs and three out of four species on Earth. Around 252 million years ago, the Great Dying wiped out about 90 per cent of the world’s species. Pimm and Jenkins said there is hope. Both said the use of smartphones and applications such as iNaturalist will help ordinary people and biologists find species in trouble, they said. Once biologists know where endangered species are, they can try to save habitats and use captive breeding and other techniques to save the species, they said. One success story is the golden lion tamarin. Decades ago the tiny primates were thought to be extinct because of habitat loss, but they were then found in remote parts of Brazil and bred in captivity, and biologists helped set aside new forests for them to live in, Jenkins said. “Now there are more tamarins than there are places to put them,” he said. –Canada

    I believe that it is possible Bio or chemical warfare is being carried out against nature. Insects account for processing 1/3 of the food we that include apples, oranges and such (pollination).
    Controlled the food, control the person. Yes, it could also be a nature part of nature, so what is causing it, then?

    If you read the first statement in this article, we, humans could be the problem. And if the inscription on the Georgia Guide posts/stone structure are correct, 500,000,000 people world wide could live in harmony with nature. So, can we expect a large human die off?

    No, I am not paranoid. The world in which we have known is dying and a new world order is raising. The president has said so.

      Nothing lasts forever. Nothing. Not even us. Even the universe will end.

      It’s fear that causes countless people to utter such words as “It’s not going to happen.”
