quote: If we had another ice age (and the records seem to show they can have very rapid onset), how will we feed the worlds population? If farmers can not reasonably predidct growing seasons or areas, how will they farm? If we remove the agricultural base from the worlds economic system, will the rest of the economic system stand? Can cities continue to exist without a steady and reliable economic and agricultural base?
Well then, we'll just have to move to Jupiter. Bring on Homo Sapiens Stellaris.
