What would you say are the most likely ways the world will end?

[chrono]

Oh there's only 1-way

The Sun will die,

Sure, we may set off a number of nukes, or there may be a large scale earthquake that kills everybody in California, or a commet may hit killing everybody, but the earth and life of some sort will go on until the sun dies.

If the ts means how will the world end then this is your answer.

Now if the ts means how will mankind end...then i say through disease or climate change natural or not.
