I think we will end up destroying the earth with a Nuclear War

Basically global warming will kill us
e.g. people are being to greedy with money therefore company's like easyjet etc.. making more planes car company's making more cars all for money is polluting the earth and eventually there will me no oxygen left in the atmosphere

I think the world will end when the sun expands a blows up. That wont happen anytime soon.

We (mankind) will be the cause of our own demise !.

I think it will either be our own technology that kills us or it will be a war over what little resources are left on this planet.

Nobody knows, the only person that knows is god

Its gonna end from nuclear war.. I'm telling you, I just know it will. There's going to be like two more world wars and during one of those, there's likely to be a nuke launched.

Do you know what? I actually hope there is a zombie attack that way you get the chance for survival.

I think the human race will get destroyed by robots.

illuminerti gives us diabetus

When will the world end - nobody knows.
How it will end - nobody knows.
