Being of the Christian religion myself, I think it'll end by the coming of Jesus Christ. Not necessarily "end" but rather a new beginning.

However, I am well aware of the things going on in the world right now. Earthquakes, tornadoes, all that stuff. However, think back to the San Francisco earthquake. People back then probably thought the world was gonna end. And here we are, about 99 years later.

So I believe it won't end anytime soon, but it'll definitely end. Eventually. Just my beliefs.
