      Many, many years from now. In a few billion years the sun will start to die and the earth will probably burn up, so I’d maybe call that the end of the world because anything still living on it would probably be burnt to a crisp!

      The sun has about another 5 billion years of life left. Before it dies though, it will become a red dwarf, which means it will expand and burn up the earth like Paul says. We’ve got another 3 or 4 billion years before that happens though.

      A long long time. Thankfully I don’t think it will be happening in either of our life times.

      A few more years 😉
      I think humans will have a big effect on how life on earth is over the next few centuries, if not decades (e.g. global warming and pollution and food security)
