What we’re talking about here — this the cost of inaction, the cost of not doing much — is a transformation of where we can be. Over a hundred, 120 years, we can’t be that precise, a serious risk of global war, really, because you’ve got hundreds of millions of people, perhaps billions of people moving. That’s the cost of inaction. It’s potentially immense.
