  I hope we will be able to build a space ship to fly to other planets by then!

  I’m pretty sure we’ll find somewhere else to live, maybe on another planet, maybe we’ll just live in giant spaceships.

  Good question! I hope that if that ever happens we have learnt how to live and survive in space for long periods of time and that we’ve built spaceships that can travel from our planet to another planet. I think we’re a long way away from being able to do that at the moment so hopefully the Earth doesn’t become inhabitable soon – if it does its probably our fault because we’ve wrecked the Earth by polluting it or via global warming. If we make the Earth inhabitable soon there is a good chance that will make the human race extinct, but hopefully that won’t happen.
