http://m.phys.org/news/2010-06-humans-extinct-years-eminent-scientist.htmlEminent Australian scientist Professor Frank Fenner, who helped to wipe out smallpox, predicts humans will probably be extinct within 100 years, because of overpopulation, environmental destruction and climate change.
Fenner, who is emeritus professor of microbiology at the Australian National University (ANU) in Canberra, said homo sapiens will not be able to survive the population explosion and unbridled consumption, and will become extinct, perhaps within a century, along with many other species. United Nations official figures from last year estimate the human population is 6.8 billion, and is predicted to pass seven billion next year.
Fenner told The Australian he tries not to express his pessimism because people are trying to do something, but keep putting it off. He said he believes the situation is irreversible, and it is too late because the effects we have had on Earth since industrialization (a period now known to scientists unofficially as the Anthropocene) rivals any effects of ice ages or comet impacts.

This isn't to say that the human population won't go down a lot. I do expect that to happen in the next few hundred years.

(135,425 posts)The population will ebb and flow. The way to reduce the population is to bring more people out of poverty, out of the grind of manual labor, so they need fewer offspring to survive. Many countries, like Japan, aren't reproducing in sufficient numbers to replace themselves. They have to rely on immigrants to keep their population up.

A global increase of that magnitude, in a relatively brief period of time, will not give most ecosystem on the planet time to adapt.

(36,063 posts)a cultural appetite for mineral resources. This makes us tremendously disruptive to natural ecosystems
Early on in my ecology training, I got the misguided notion that being generalists was good, because it protects against specific resource shortages. Likewise I had the notion that organisms living in mutualistic relationships with reciprocal benefits was a good thing since all members of the mutualism benefit.
I was dreadfully wrong. As I came to better understand the dynamics of community ecology I realized omnivory and mutualism are actually very DESTABILIZING to communities.
Humans exploit the biota at almost every level and we don't shift from one resource to another. We are the most omnivoric omnivore on the planet. We consume whatever is consumable at all levels and do it simultaneously. We not only exploit for food, but we exploit for shelter, clothing and cultural supports. We've even turned to consumption of minerals for energy and materials subsidies. Our vagility, ability to disperse, has spread our direct impacts globally. Just think about how a tiny nation in the nw pacific, exploits endangered populations of marine mammals in the extreme southern oceans. That consumption takes not only an appetite for something other than rice, that takes technology, mining/smelting, huge fossil fuel subsidies etc.
Through domestication we have developed a wide array of mutualisms which have expanded the 'footprint' of humans and their mutuals. And I am not talking about humans and their dogs and cats. I am talking about humans, livestock, and row-crops. Among the three greatest causes of extinction so far along this great extinction event are habitat alteration/destruction and desertification. Both are mostly a consequence of the impact of agriculture based on domesticated mutualisms. Modern maize basically can't survive without humans and we can't survive without it (although we'd be healthier without corn-syrup).
As a species with capacity to exploit minerals, we also consume geological features for energy and materials. Some for traditional needs like shelter, but also for tools, transportation and storage...we make an amazing array of plastic bottles and soft-metal containers. Our exploitation of minerals greatly disrupts habitat, exposes mineral toxins to erosion and surface contamination, and by providing energy and material subsidies helps us expand our search for further exploitable minerals to every corner of the planet and now we are eyeing off-planet opportunities.
Of course, all this human and agricultural activity impacts nutrient cycles and we are well aware of their local and even regional impacts. But because of the dysfunctional nature of our pro-growth prowess we're also overloading our human modified (mostly simplified and industrialized) global environment at a global level. Our planet's atmosphere and our oceans are changed because of humans collateral production of toxic detritus.
And we've done it -not- because we are an apex species at the top of a food-chain, or the top of a community pyramid shaped food web. Humans have done this because we are vagile mutualistic generalist consumers engaged in geotrophy (consuming minerals).
We are the most dangerous species on the planet because we -are- omnivores with an aptitude and a culture for consuming -everything- and making and leaving a global-sized mess as we do.

Anyway, on topic, I can easily see the near extinction of all life on this planet. We're already pushing farming in some places, and if the climate becomes unsuitable in the so called "bread basket" areas, what happens then? Total disruption of the food chain, with massive expenditures needed to retool and relocate.
I would die without air conditioning. I don't sweat like most people, and get overheated quickly, even in the winter. If the grid went out in the summer, I likely wouldn't last long, and it wouldn't be a pleasant way to go.

(15,376 posts)Too warm a winter, we lose orchards (apples, cherries, nuts, peaches, etc...) because it's not cold enough to set blossoms. An warmer than normal or inconsistent late winter/spring, we can lose a high percentage of our grains, animal fodder and early vegetables as they start sprouting before the spring thaw is over or flooding can mess with fields. Not enough snowpack, drought - there's not enough water to take agriculture through to winter.
And you aren't going to get most American farmers and Agri-businesses to suddenly change their farming practices for more drought-compatible practices "overnight" because: 1) most American farmland is already tilled, which makes it more water dependent as the soil drains too quickly to keep the roots moist, 2) most American independent farmers can't wait out the three/four years it takes to properly restore their farmed soil for drought resistant farming, 3) Most agri-business pretend that their patented "drought resistant" seeds are truly drought resistant by themselves, and they don't have to change their farming practices as well as their crop rotation processes in America to maintain the level of production they have now, and 4) most farm animals aren't able to handle the physical stress of both temperature increases and climate change along with the current "cost effective" farming/ranching practices.
That means food shortages and high prices. Which means population stress which increases both social morbidity and general craziness.
We in the US are really very selfishly nasty when it comes to not being able to just get what we want when we want it, especially when the financial interest of those who control most of the resources for survival outweighs their social interests so all the mitigations we could put in place to correct the problems and make life better/easier for everyone become "just too expensive". Culturally, we tend to tell ourselves it's better to get rid of the weakest links in society, totally forgetting that as we start getting rid of the "dead-wood" beneath us, we're going to eventually find ourselves with nothing below us and those above us will cut us
out as dead-wood in their efforts to stay on sound footing.
Psychopaths (including organizational constructs that are now considered "people"
don't care what happens to anything or anyone so long they can survive in comfort one day longer than whatever is around them. If they're the last ones left standing before burning up the world, so be it.
And we as a species tend to put psychopaths in charge, because they're so damn impressive in their displays of wealth and confidence...they must be better than us, look how rich they are!
So yeah, if things keep going the way they are going - without a radical change happening right now - I can see humans and most species on earth as we know it going extinct. Maybe not in 100 years, but I still doubt the generation of my grand-daughter's grand children will have much of a world left for them to live in. And it'll be the collective "our" fault, because we prefer to just throw money at our "problems" and try to buy them off than spending time, curiosity, effort, and informed sacrifice.

With all this evidence about climate change, we've had the most normal year in 2015 that we've had in nearly a decade. Now we're looking at an unusually warm winter (it's been in the 70s, in December, about 20 degrees above normal), and who knows what that's going to do for the crops next spring.

If they did bring enough worker-bees to maintain them at the level they think they deserve for the generation or so "until things settled down" underground or in a bio-containment area, the society they thought they were building would implode. People don't do well in isolated communities over a long period of time as it is; add the danger of rigid safety and social mobility rules to avoid environmental degradation or contamination in that isolated community is a recipe for disaster. If you can't "go outside" or get away occasionally just to let off steam, the society will go crazy.

(6,960 posts)It seems that Pres. Obama's messages about the critical importance of the global warming issue have fallen on deaf ears.
Of course, as President, publicly he can't be anything but optimistic.
But the science is telling us a very dire future awaits us if we don't adopt crisis procedures now to mitigate climate change.
The belief that somehow, some way technology will miraculously pull us back from the brink at the very last moment is instilled pretty deep in 21st century Americans. We just cannot imagine any differently than that tomorrow will pretty much be the same as today -- our great flaw as an intelligent, thinking species.

(76,635 posts)Or is it just reasonable disagreement with the time line proffered? Despite the warming of the atmosphere and the acknowledged effects of it on land, farming, and the human body, 100 years seems an awfully short amount of time to me too.
I don't doubt the science at all. But, i question where 100 years to EXTINCTION comes from. That means NOBODY survives, despite the broad genetic diversity sperad among 7 billion people. That defies credulity, whether i believe in the catastrophic effect of radiation absorbing gasses entering the atmosphere (and i do) or not.

A Planet Full of Hitlers
The world's billionaires, led by the Bush "madministration," are acting like a planet of full of Hitlers. They are willing to invade whatever region in the world has what the world needs most -- oil.
Black gold. Texas tea. Petrodollars.
They figure they have all the money. And basically, apart from a Soros here and a Gates there, they do.
And thus, the worlds billionaires and their hounds of the BFEE want to spend it all before they die. And they have the plan and cash on hand to do so.
Consider the Bush agenda: All War. All the Time. Government spending for the MI-Complex, transferring trillions to the wealthy corporate owners, war and all.
These are the likes of the industrialists Mussolini, Franco and Hitler so loved.
And like the fascist trifecta, the American fascists of the BFEE have bought all the political power. Don't just think Tom Roach Motel DeLay and Mr. Friskie Frist. Remember Prescott Bush and Averell Harriman and Allen Dulles and Rheinhard Gehlen and Igor Orlov.
What can we do about it? Theyve bought all the legal power, built law schools for Federalist Society AND Opus Dei judges. Think Bill Eagle Eye Rehnquist and Antonin Fat Tony Scalia.
These turds of the BFEE have worked all the tax breaks and bankrupty laws for the rich. Uncle Sam reverse-Robin Hoods wealth to the top 1-percent of country.
And what do these rich turds who prop up Bush use their tax savings on? They certainly haven't invested it in making America a better place to work or live; they've invested in "off-shoring."
Lots of the tax money goes to buy more vacation homes, yachts and jet planes. Most goes offshore to the Caymans and Switzerland.
And of course they want more without having to pay for the damage to the environment. Farmland depletion in the USA. Rain forest depletion around the globe. Oceans getting acidic. Fish stock depletion. Global air pollution and water shortages.
Well. OK. Maybe a case can be made its the rich folks money. They can do what they want. But they should pay their fair share of taxes! After all, the rest of society helps keep them in their position. And its our brothers and sisters in the armed forces who are giving their lives to keep their oil and power and privilege.
Budget red ink means no money for middle class. No money for schools. No money for cities and suburbs and farms. No money for roads. No money for science and R and D. No money for the future.
And the media? What media? What Fairness Doctrine?
They cover up their materialism and venality with all the talk about Faith-based this and Conservative-values that. But the reality is these are sinister wolves and satanic bed-wetting bastards in sheep's clothing we are dealing with.

Wasnt that what Bush really meant when he told Bob Woodward History? Who cares about history? In a hundred years well all be dead.
Just like Hitler. And just like Hitler, Bush wants to take us all with him.

But homo sapiens is a tough and adaptive species, which is why I don't think extinction is inthe cards.

I don't worry about rising sea levels and tensions so much as about disrupted agriculture and infrastructure. I remember an unusually big snowfall just a few years ago. Roads were closed for only 24-36 hrs in our area (a small city) right before Christmas. We could get around in our 4-wheel drive but suppliers couldn't. One day's disruption and the shelves were bare. One Day! It illustrated just how fragile our system is.

I don't think any amount of enlightenment would be able to allow us to overcome our basic selfish egotism. Face it, we are a poor design and will go down in history as the least successful mammal that ever lived, in terms of enduring. Our 200,000 to 300,000 year stand is laughable in evolutionary terms. We will be the "Short-Gevity" champions. (the opposite of "longevity".)

The ability and wherewithal to worry about the future is unmatched in our time and is only getting stronger. It might be or might not be conscious desire at any one time, but moreover it's a strong genetic trait many seem to miss.
