End of the world prediction?

When do you think the world will end and how?

The fact that no one has touched this yet is interesting. I'm interested in how materialists think on this subject.

revolution of a civilisation or an outer space object collision

Im not too sure man, maybe space invasion? or a meteor hits the earth again

year 5000 maybe with the world overpopulated and the lack of water and food for everyone and the ozone layer gone making earth into venus or worst
