We’ve spent so long fantasising about living on inhospitable planets it’s not too much of a leap to imagine earth as one. Ala planet of the apes [spoiler alert] though, could a time traveller end up on earth in the future and mistake it for an alien planet? Could we do this with 7 billion people though? Will my children make it to this world? That’s what keeps me up at night.
