Do you think this sort of scenario where the concept of borders and nations changes as we move forward into this climate crisis, do you think that's a realistic way to look at things? I think we're going to have to change the way we look at human labor moving across borders. And if you don't like this as a solution, then what is your alternative solution? Because is it going to be increased conflict? One thing that struck me, Gaia, is that your book is a combination of climate science, this and sociology, anthropology, economics, it's a lot in there. But of course, we very much do live in the real world.
