World On Brink Of Sixth Great Extinction, Species Disappearing Faster Than Ever Before

WASHINGTON (AP) — 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 study lead author noted 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 and 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."

    said Dalhousie University marine biologist Boris Worm,

    Well, there you have it....the king of "the sky is falling" praised it...I'll let you draw your own conclusion what I think.

    PS... It's a darn good thing man was not here to stop any of the *other* five mass extinctions...we'd be up to our ****'s in trilobites and T Rex's....:rotflmao

    I think the world will be fine without the buffy-tufted-ear marmoset, but what do I know??

    Chicken little BS.

    We still have trilobites, only now they're called horseshoe crabs!!

    Thanks for the lesson in 'forum etiquette' daddy....

    If I asked, its because I don't know. I do however agree that 7 Billion people and growing on this planet, is putting an enormous strain on our natural resources and natural habitat.

    It doesn't take a genius to figure out, as more people are looking for cheap sources of protein, our worlds oceans are under attack by increasing commercial fishing interests.

    I'm surprised no one has commented on the fact that Mr. Pimm's comments were coming from research at the Dry Tortugas....I know that bothered me....alot!.

    Although I recognize that we don't have a good handle on the actual number of species on this earth or the rate they are evolving, I'm in the "scary" camp.

    The better question, at least to me, is what, if anything, should we do about it?

    Stuart Pimm's credentials bring credibility to his research and his opinions. He has his share of awards and accolades and he his held in high regard by his piers.... at any rate, he knows a great deal more than I do about biology, ecology and the global environment. I am in no way qualified to question his assessments.
    Since I did not read the results of the study, I don't know what it states, I only read the article as stated above.
    The article states that species are disappearing at a rate exponentially greater than before humans inhabited the earth.
    That's not hard for me to believe.
    It also states that the world may be on the "brink" of extinction.
    Since the world has been inhabited by complex organisms for more than 250 million years, the "brink" could put us within a 100,00 years of mass extinction.
    I can't argue with that statement either....
    That's a long time in my paradigm.

    Drawing on my native North Miami,Florida Weekly Reader,Chamber Of Commerce and other learnings circa 1960's..........no doubt The Future Is Rosey!....three day work weeks.The Oceans will feed us.Everglades tamed. Exponential "Growth" to be accommodated by leaps and bounds in technological advancements sure to soundly address "Growth" 'problems'.
    The loss of 'specie' a given,terse acknowledgement to The Advance....and what the heck,even Science would avert Extinction .....even of our own species.
    We were destined to further embrace "Diversity" (specifically, accommodating another but one single race...think about 'dat...)
    The westward expansion of "Miami" clear across the state through Collier lands,to the Gulf likely assumed, but never openly acknowledged-until "The Jet-Port".Big Cypress Preserve.Adition Lands- et al.

    We might assume we are still in Catchup Mode

    For me, personally,it has been of great insight to ramble,camp,hunt and live among sandhills and creeks that are but 'ancient' spillways flowing out of an ancient tidal pool....and destined to flood again,relatively 'quickly',the vast majority of "Florida" awash.
    So even the foremost Hunter/Outdoor/Fisher driven conservation legacy...or lack thereof.......really does not matter.
    Hunters are present yet relatively uncommon in Florida :wink

    A "coleccioism"?
    Oh, OK.... I thought it was an "ambiguity".
    Thanks for chiming in and giving it a monicker, although I still don't know what it means, and that's fine.
    I was hoping to get some clarity on his viewpoint, but it's unimportant.
    If I really wanted to know, I suppose I could go back and look at his posts and gain some insight.
