Not meant to be a Downer Debbie thread. Humans, like any other critter, will become extinct at some point in time. Curious as to what you folks think.

Quoted: Not for a very long time. While it's all well and good to say this, a meteor strike of only 2Mi in diameter (a relatively mediocre sized one) would cause the extinction of every life form on the planet that required photosynthesis and or survived as a product of photosynthesis. We could all die tomorrow, or we may not see a meteor strike for millenia. |

There have a few mass extinctions of unknown cause, but that is something different. Humans are just getting started, and there has not yet been such a successful adapter. |

Typical mammal species survive for about 2 million years and then go extinct, typically a cousin species takes over the nitch. There are always exceptions.
The round faced bear lived in some for or another for about 10 million years. It became extint during the last ice age. Modern brown bears and black bears migrated to north america some 700,000 years ago. Brown bears are and endangered species and may not survive. Black bears are thriving better than ever and will likely continue to thrive no matter how conditions change. |

On the whole, when the dinosaurs went extinct, it's hypothesized that a very large meteor struck the earth which threw up a dust plume that blocked the sun out for years. Add to this ash buildup from erupting volcanoes due to the impact, then you have a nuclear winter scenario. Such an event will almost surely kill off mankind due primarily to starvation, disease and the elements. Many scientists have hypothesized that photosynthesis globally actually ceased. How it was restarted I have no idea, but here's an interesting and brief read on the subject. http://serendip.brynmawr.edu/exchange/node/1883 |

The decedents of our species may well survive until the heat death of the universe. But humanity won’t last much longer.
We are finding ways to manipulate and control our own genetic code. We are also finding ways to integrate ourselves into machines and computers. If this trend continues then humans won’t likely be recognizable as human a thousand years from now. We will have effectively become a new species. |

Unless science/engineering comes up with the necessary technology to ensure our existence, I don't see us getting to far beyond another 1,000 yrs.

If a giant rock doesn't kill us all before we can move out of the solar system, i'd guess a few billion years.

In December 2012, Mahmoud Ahmadinejad will hurl a large comet from the sky the size of Texas piloted by Al-Qaeda aimed directly at Israel = end of the world.

Humans are very adaptable. For instance, we evolved in a time when the earth was warm but yet survived during the ice age.
Our intelligence will serve us well for adaptability. We can live almost any place on earth while most other species are confined to smaller areas. At least a few of us will be around for a long time barring a major event but “a long time” is not forever. |

If the human race evolves enough and leaves this planet spreading throughout the universe, then never.

Quoted:
If the human race evolves enough and leaves this planet spreading throughout the universe, then never. Not physically possible. Entropy will eventually increase to maximum. |

Humans will never go extinct we are too adaptable. We are the universe's virus we will eventually move out from earth and begin the domination of all other systems and planets. Humans are the demons of the universe that all other life forms will eventually come to fear. We are the future of the universe.
This is our destiny to be the conquers of the universe. Our species is one of violence, war and domination thus we are the universes perfect weapons. Human history is dominated by our endless need for war. We have been at war since our very birth. That is what makes humanity special we are the warrior race. Be not ashamed be proud of our ability to crush, kill and destroy. Long live humanity, long live our forever war. God bless us in our holy crusade to crush the heathens of the universe for the glory of gods creation HUMANITY |

I gotta be an optimist. My first thought was to post Aenima by Tool. |

I'm guessing that humans will go extinct once the last human dies.

Terrible poll, doesn't even allow for a 'never' answer, already betrayed by the OP's use of 'WHEN' in the title.
The base premise is wrong. We're a helluva lot more capable than the animals that 'go extinct'. The OPs question utterly ignores that, thus equating humanity with animals. It's a very leftist viewpoint (whether he's aware of it or not), holding that we are not of any importance, deserve no special consideration, incapable of any great / worthy achievement or future. Just march along to the showers / ovens / abattoir, you sheep. Forget those crazy ideas about having any greater purpose or worth. Practically reeks of emo / nihilism. |

I have faith the human race will survive and spread through our galaxy with the aid of technology. Humans are explorers. We love to discover.

Whenever it is I sure hope they give me some notice, I have a library book coming close to being overdue.

There just isn't all that much compelling evidence for these "huge disaster" hypotheses for extinctions. While there is good evidence that a meteor hit Earth at that time (one big enough to do some serious damage), most of the rest is story telling and stacking hypotheses to reach conclusions. The one for the extinction of ice age megafauna is particularly bad. |

When it happens it'll be an unexpected bolt out of the blue; most likely a pandemic of some sort.
Maybe in a hundred thousand years, maybe tomorrow. Unless we spread our species beyond the confines of this planet first. |

Unless we spread our species beyond the confines of this planet first. A pandemic will not cause the extinction of the human race. Maybe back when there was only a couple thousand of us living on the planet...not now. Anything short of a severe asteroid hit or other global catastrophe that has serious impacts on the climate will not be able to take us ALL out. |
