Mass extinctions and the future of life on Earth | Michael Benton | TEDxThessaloniki

Are we really on the brink of a new mass extinction? Palaeontologist Michael Benton explains how scientists trace the history of life on Earth, examines the data on biodiversity and addresses the question we all dread to ask: Will the Anthropocene mark the end of the world as we know it?Michael Benton is the Head of the School of Biological Sciences at the University of Bristol and a Fellow of the Royal Society. A key theme in his work is the Permo–Triassic mass extinction, the largest mass extinction of all time, which took place over 250 million years ago, where he investigates how life was able to recover from such a devastating event. He has made fundamental contributions to our understanding of the history of life on Earth and he has written more than 50 books, including palaeontology textbooks for students and a children's book on dinosaurs.This talk was given at a TEDx event using the TED conference format but independently organized by a local community.

Can we get off the planet before the next one?

Denialism is another form of insanity that is prevalent these days. Despite the best efforts of the denialist community to try and refute any claim that ecological collapse is actually in progress, deep down inside they acknowledge the truth. They are fully aware that a perfect storm is now forming, but the coping mechanism for these people is just to deny every piece of evidence that becomes manifest. How more obvious can these catastrophes become--- a human population explosion as 78 million more human consumers are added to an existing population of 7.600.000.000 every 365 days while during this same time frame, thousands of animal and plant species are driven to extinction aka “6th Mass Extinction Event” due to pollution, chemical contamination, desertification, oceanic dead zones, ocean acidification, mass coral die-offs, deforestation, ground water depletion, etc.\nWhy is it so difficult for the denialists to comprehend that the Earth's life support system depends on an intricate chain of life. As mankind destroys link after link in the chain of life through species extinctions and other environmental pillaging, at some point soon the entire ecology will implode, and mankind will follow many other species into the extinction abyss. The signs are everywhere, In North America, Honey bees and native pollinators are in a steep decline. Bats are dying in the millions due to White Nose Syndrome (as with the bees, a combination of negative factors is causing the immune system of bats to crash), and has spread from the Northeast to the South and Midwest. Amphibian species around the world are going extinct in unprecedented numbers due to Chytrid. With the loss of each species, another intricate link in the chain of life is lost.

Though this bs about this T-Rex is irrelevant in my opinion, he's right. We have been fuelling a heat engine for many many decades (about 20-25 decades), and we felt like a frog in heating water, we could afford that for a long while, I think the sting will be in the tail. It will go haywire in no time at all, 12-20 years, starting within a few years from now. There is not much we can do now, which will have a positive effect, the damage has been done. Within a few hundred million years, there might have been risen a conscious out of some amphibians or insects, and they will find some of the stuff we had been making, and try to guess what killed us off. Who knows.

Trippy. It's funny when scientists bash each other over perceived intellectual superiority.

Reminds me of a temporary duty trip to thessaloniki way back in 1982 :) ...from Athens... and the Mass extinction is well under way... just look out your window at the weather. :)

Gourmet mushrooms are considered meat when seasoned & taste like it with nutrients & medicinals. never injected with drugs, etc. seasoned Maitake taste like steak, Oyster Mushrooms-Chicken. Lions Mane-seafood lobster. According to Paul Stamats research they have more protein than cattle & fish. He owns the company Host Defense, You can find him on You tube etc. A wise elder. COOK WELL while pressing down with Maitake Steak Mushroom. YUM!! neurological, brain & other benefits.

Don't limit your diet to eating 4 animals. Expand your diet to the millions of species of plants and fungus. Save the world by going vegan.
