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.

Forgo the anchovies.
For a start.
and, of course, the Squirrels.
Does anyone have a Chicken Little graphic, preferably animated, that can be used with these stories?
Something like the “Oh No, not this $#%& again” photo.
NOT my fault.
I swear it.
*Frantically trying to plug the cord back in*
/ bad joke.
These guys just cannot let go of their pseudoscience religion, can they?
But only liberals will be affected - unless they immediately leave the plant!!!!!!!!!!!!!!!!!!!!
Speculate in one hand and crap in the other, and see which fills up first.
Take away the scare story aspect and the science is essentially true. The sun and natural causes can cause the temperature to change or other aspects of the environment to change in ways that are absolutely devastating to life, including human life. The several degree temperature change that caused the Little Ice Age was catastrophic to man and that was a “Little” Ice Age. A true Ice Age would be catastrohic to us even with our technology. This is just a fact we have to live with. We aren’t as important as we think we are, either in terms of impacting the environment or being able to master it.
Na man, get laid THEN enjoy the pizza.
I thought that species were supposed to compete and the winners were to move on while the weak perished to the dustbin of history.
Isn't that what their precious evolutionary theory is all about? If so, then why does Human existence remain outside of their theory as if we are an alien race on the sidelines of evolution?
They can't have it both ways and on top of that these eco idiots have the hubris to think that we are now at the end of evolution and that any change is bad. According to their theory evolution does not stop and thus we are just moving along the time line.
These idiots need to make their thinking a little more logical if they are to be taken seriously.
Huge reset button. Google Hillary Clinton plus Reset.
We will become a third world, primitive country and worship the earth. Of course Obama and his tribe will live like royalty because running the country into the ground will be very stressful annd require enormous endurance to LIE so much and make it happen.
Same old recycled crap. Over 40 years ago it was population bomb, food supply, water supply, cycles of starvation, blah, blah, blah.
FUBO
Is seems that Liberals have only a grudging respect (if at all) for the intellectual prowess of humans. Then, they pick and choose how and where blame may be attributed to humans for everything that is wrong with the environment. How many ways can they have it?
They need to accept humanity wholly and heartily for what it is and take it from there.
Since we are all gonna die anyway, I just choose not to give a $h!+. /sarc
Start with the liberals and the lawyers!
Only if you do both simultaneously.
Multitasking....do both simultaneously.
Guess I better stop driving herds of mammoths over cliffs.
