The human race is looking at a threat that will destory all living beings...How would you want the human race to end?
The Earth hurls into the Sun.

Of course I'm sure if this were ever to happen we would have some notice.I'd be on the first plane to Ireland.A wish of mine since I was a wee one.
I would love for us to nuke ourselves, leave the world to the cockroaches....

Well looking at American presidential candidates that might just happen.Oh if only I believed in reincarnation.
I'm not sure if I would want to have a lot of forewarning or something more instantaneous.
If there was a lot of forewarning, like slowly falling into the sun, I think the world would go into chaos since many people would disregard laws and the usual responsibilities. I doubt things like airlines would continue to run normally since employees in all businesses worldwide aren't going to want to keep working at their jobs if the world is ending. In the movie, Children of Men, the scenario of worldwide sterility is a very slow extinction, and shows a chaotic world caused by the lack of children.
In a fast extinction scenario, everyone goes about life as normal, and then POW everyone dies. One such possibility (although very unlikely any time soon) is a gamma ray burst aimed at Earth (http://www.space.com/scienceastronomy/astronomy/gammaray_bursts_010522-1.html). Hopefully a gamma ray burst is almost instantaneous death and not a prolonged radiation burn.
Alien invasion.
OOH! I love this thread :D
Daeth by internet addiction. We create a metaverse so appealing and addictive that we can have have anything we desire in the virtual universe. Then we forget our physical bodies and neglect eating, sleeping, dental care and procreation.
But we all go with big, cheesy grins on our faces.

The Earth's orbit takes it through a huge cloud of alcohol vapour which is drifing in space. The cloud is thin at first, then gets denser and denser.....
I'm going for the ironic ending:
A group of fundies invents a highly contagious virus to "cure" homosexuality.
However, due to a random evolutionary mutation in the virus, and an accidental release from the lab, it ends up turning everyone gay.
The human race dies out in one generation due to lack of procreation.
... but as the end nears there will be FABULOUS parties!!!
(plus, designer coffins and urns will be all the rage)

Americans become so fat that the collective weight drags the North American tectonic plate down into the mantle. In response to the loss of part of the crust, the other plates float into the big, gaping, molten hole. The massive earthquakes are enough to destroy the whole world. As the last inhabitant in the world is about to perish, he curses the heavens: "YOU MANIACS! DAMN YOU, MCDONALDS! DAMN YOU ALL TO HELL!"
I'm going to enjoy this thread...
A group of CEOs and international bankers plan a final solution: a disease that only effects the poor. As they've been shitting on the poor for decades, if not centuries, this seems the next logical step. The only cure is to pulverize thousand-dollar bills and inject them into your bloodstream. Soon all of the third world falls, then the rarely mentioned second world. Finally, as the American and Western European economies collapse due to the fact that they can't exploit labor from the third world, the CEOs and international bankers realize their great folly: the "poor" are actually the foundation of the entire planetary economy. Without them all are poor. As Paul Wolfowitz and Kenneth Lay finally start seeing symptoms of the disease, they chronicle their mistakes so that whatever species replaces humans some day will learn that being greedy and not appreciating everyone for their contributions will eventually lead to a civilization's downfall. That and biological warfare.
Entropy.
At the farthest end of time mankind, having reached its full potential will peaceably fade away as the universe finally wears down.
Or, Mother Earth, having tired of the infestation of mankind, goes through a series of catastrophic natural disasters, climatic changes, and volcanic eruptions that it fumigates itself and allows a truly sentient life-form, free of superstition and self-importance, to arise.

True but think about how ironic it would be.Something we made unmaking us all.

Will I can tell you have thought alot about this.Mommy hold me.
All of the adults on the planet have sex simultaneously and throw the orbit of the Earth off track, and we spin wildly out of the solar system. We all freeze, of course, but not until we spend some time under the covers trying to keep warm. I guess this is the final big bang.

Hahahahaha! I love it!! Oh the irony!!
Nearby supernova. The destructive radiation would reach as at the same time as the light, so we'd never even see it coming.
You read right. The entire Earth could be destroyed instantly, before astronomers even saw it coming.

You have to admit this would be a fun way to go!I wonder would there be something to cause all of this sex?Maybe a group of terrorist plant what they believe to be deadly nightshade berries (cheaper then arsenic) ,but turns out to be a harmless aphrodisiac.
I would love to see the Vogon Destructor Fleet demolish the Earth to make way for a new interstellar bypass.
Quote from: "Tom62"I would love to see the Vogon Destructor Fleet demolish the Earth to make way for a new interstellar bypass.
"There's no point in acting all surprised about it. All the planning charts and demolition orders have been on display in your local planning department on Alpha Centauri for fifty of your Earth years, so you've had plenty of time to lodge any formal complaint and it's far too late to start making a fuss about it now."

and later on find out that it wasn't needed after all.
I'd like to think that the humans could all leave the earth in relatively good condition so that nature could take hold again. I'd feel really bad if a human created cataclysm takes all animal and plant life with it. Animals do not deserve that

Of course, most animals will surely die as a result of two of those scenarios and probably die as a result of the remaining one, but as long as life itself survives, in time the Earth will probably be inhabited again, maybe by creatures more advanced than us.
Dinosuars cloned to walk the earth again.Eating every human in reach until we are all gone.Then and only then will Jesus come back!Why you ask....to ride them of course.
