Mass extinctions have served as huge reset buttons that dramatically changed the diversity of species found in oceans all over the world, according to a comprehensive study of fossil records. The findings suggest humans will live in a very different future if they drive animals to extinction, because the loss of each species can alter entire ecosystems.
Some scientists have speculated that effects of humans - from hunting to climate change - are fueling another great mass extinction. A few go so far as to say we are entering a new geologic epoch, leaving the 10,000-year-old Holocene Epoch behind and entering the Anthropocene Epoch, marked by major changes to global temperatures and ocean chemistry, increased sediment erosion, and changes in biology that range from altered flowering times to shifts in migration patterns of birds and mammals and potential die-offs of tiny organisms that support the entire marine food chain.
Scientists had once thought species diversity could help buffer a group of animals from such die-offs, either keeping them from heading toward extinction or helping them to bounce back. But having many diverse species also proved no guarantee of future success for any one group of animals, given that mass extinctions more or less wiped the slate clean, according to studies such as the latest one.

Or not.
Anthropo scene ping.
Creating unwarranted anxiety so as to prepare people to accept stupid political agendas.
who published this... the same people who blew up both oil rigs????
Have I got time to get a pizza and get laid?
If that still works. There's a saturation point for everything.
I’d be worried more about a massive solar storm quite frankly. This is all B.S.
My guess is that addressing this problem will require massive new taxes and draconian government control of the entire world economy.
Just a guess.
Another Discovery Channel threat?
“But having many diverse species also proved no guarantee of future success for any one group of animals, given that mass extinctions more or less wiped the slate clean, according to studies such as the latest one.”
Kind of like diversity in America.
The Anthropocene epoch- where we become less intelligent than monkeys with self-destructive philosophies that enable our own extinction. AKA-AGW.
It’s 12/21/2012 all over again!
Notice the excessive use, in the article, of “if”, “could”, “may”. Sounds like the speculative rambling of the religion of climate change and its new age goracle fear mongers.
First, kill all the children.
Second, don’t have any more.
Bingo.
In 50 years or so, “problem” solved.
Mass extinction of donkeys on Tuesday, November 2, 2010!
