For Shah, migration has always been the rule rather than the exception, but it will become even more common as the planet warms. The low-lying country of Bangladesh has a population of more than 150 million.

Those 30 million will be forced to move, and when they do, it will matter how they’re regarded. As “Bangladeshis” perpetually out of place, they will likely struggle to find safe berth. It would be better, Shah suggests, to drop the labels, recognize human beings as a migratory species, and build institutions around that fact.
