Question: When will the world end?

I don’t know, but it will probably be when the sun dies (but that won’t be for billions of years).

There might be something like a massive asteroid or global warming that has a big impact on the conditions on Earth in the meantime, which might mean that a lot of species may go extinct and population sizes will go down as the Earth is less able to support the levels of life that are here today – but those types of things are unlikely to destroy the planet completely, so it depends what you mean when you say the “end” of the world.
