According to almost every religion on the planet. And pretty much anything can. An asteroid. The sun going out in 3-4 billion years. Global warming. Nuclear weapons. Sorry but that's a really broad question. Anything, like I said, could do the trick. And this was not a happy post... Hmmm...
The world will end several billion years from now when Sol runs low on fuel and swells up to a red giant. Human civilization will end looong before that, and the world will be a much better place as a result.
The Earth will be around for a LONG time to come. About 4.5 billion more year, and it's end won't come from asteroids, nuclear war or any other man made causes. It's end will come when our suns supply of hydrogen runs out causing it to burn it's supply of helium and become a red giant star. Swelling up to around 3 times its current size and swallow the Earth. It is inevitable our sun is going to die and when it does Earth will be destroyed. But just because the Earth will be fine for a long time, doesn't mean humans will be.

Of course it will, I presume the world will end of a Nuclear war sometime in this century. I've seen humanity enough to see what power it could unleash for an insane reason. But if a miracle happens and Earth doesn't have a Nuclear war(Highly unlikely) then the Sun will increase in size and either devour the planets or explode and destroy the inner planets.
