I propose we deal with them with belt-feds.Mass migration will become worse as civilizations collapse due to volatile climate conditions. Civilization was built in large part because we built a lot of complex systems that gave us relatively predictable access to food, water, and safe shelter from the elements. If access to food, water, and shelter becomes less predictable due to meteorological events or wars caused by scarcity, then civilization falls apart. We need to be prepared to deal with the impending collapse of governments and societies around us.
