Yep, but unlike yeast we are a much more adaptable critter. Since the last mini ice age we have made vast steps forward with horticultural technology. With the abundance of manufacturing industries having been "outsourced" we have an abundance of large scale industrial buildings which could be retrofitted to act as massive indoor gardens. Nuclear & Geothermal technology could ensure a consistant source of power with which to produce energy for lighting these grow houses. And for the rural areas, theres always the hothouse and / or bio-dome options. Somewhat pricey yes, but when faced with a potential global catastrophy and the consequences of failing to act in the best interests of our species survival it's likely that society will learn to adapt. Either as a whole, or as wingnuts living off in the hills, using the shells of old mobile homes as private or co-op large scale terrariums. Come to think of it, it might be good to refocus our beef industry over to raising Buffalo (nothing against your pimp assed ride aumbrella ) I think they're more cold hardy creatures. Of course all this only applies if we do indeed slip into a deep freeze. Thou even for now, the indus-terrerium would make interesting use of currently existing vacant warehouse space.
