What is the most likely incident to happen to wipe out all of man kind?

Answer 1

Most likely? Makes me sad to say it but Nuclear War, to many evil people have access to that technology now :(

Answer 2

A super eruption at Yellowstone Park or one of the other Supervolcanoes.
Or a catastrophic extinction like the one that killed off the dinosaurs.

Here is something I once heard:
If there is anything we can learn by looking at the history of life on Earth. Is that nothing lasts forever. And we humans are just another large mammal.

Our species was nearly wiped out before when Lake Toba erupted 74000 years ago.

Answer 3

There are plenty of possibilities, each with different probabilities. Here is my take on the question:

*Sun going supernova - Would definitely do the job, but it's so far in the future that it's unlikely that we would still be around

*Nuclear war - Relatively likely to happen, but I could see the human race surviving this one

*Meteor impact - Again relatively likely, and a fairly good chance of causing a mass extinction possibly including the human race

*Disease - Has potential to kill hundreds of millions even with todays' science, but probably wont lead to an extinction of the human race.

*Supervolcanoes - Relatively likely, and those not killed in the initial eruptions would probably die of hunger or poisoned in the following weeks/months/years. This is my favorite... After years of laying waste to the planet, Earth rises up and wastes the human race.

Answer 4

We know that the sun will burn out eventually and will destroy the earth in the future so that means that this planet already has a limited lifespan.

At the rate we are going it will be mankind who destroys itself unless we persuade the US and China to cut their emissions. Failing that it would only take the nuclear powers (France, UK, USA, Russia, India, Pakistan, Israel, China, North Korea, South Africa) to declare nuclear war on each other and it's goodnight planet.

A large meteor could destroy the planet (Armageddon anyone?)

If a large leakage of a virus such as Ebola or Smallpox got out (probably by terrorist means) then this could wipe out the planet. ( like in Stephen Kings - The Stand)

Answer 5

Huge meteroid.

'Approximately 20 to 50 rock-like objects fall every day over the entire planet, said Carlton Pryor, a professor of astronomy at Rutgers University'

..."We know that meteors have struck the Earth hundreds of times," Ellwood said. "If I had to guess, I would say that once every 5 million years a meteor big enough to cause a mass extinction hits the Earth.

Answer 6

Either a meteor hitting the earth that is large enough to cause a nuclear winter over most if not all the earth, or several countries launching bombs at each other at the same time.

Answer 7

George Bush

Answer 8

The Sun going Supernova.

Answer 9

There are probably two. Either we anihalate ourselves through war or we manage to trigger a major climate change, similar to the little ice age that occured only a few thousand years ago. temperatures dropped just enought that crops failed and diseases ran rampant.

Answer 10

A meteor hit large enough and similar to the one that wiped the dinosaurs out....
