How do you think the world will end?

When it is the final judgment, everything will be over.

Either hit by an asteroid/comet; nuclear war or destruction of nature due to depletion caused by our market economy which makes us consumers claim to consume ever more. There are limits. Those who do not believe that are usually uneducated folks or greedy people who only care for their own wallet and bank account, owning many cars, yachts and houses. Also, if many people and nations fight for few resources, this can lead to wars and already has led to wars in the past.

Nuclear apocalypse or robot uprising. Either way, humans will cause it.

When Judgement Day come and everything will be wiped out.

Corrupt politicians on a power trip starting a global nuclear war.
