Farming just Antarctica would probably produce enough food to feed the world several times over.

I'd bet a paycheck that there's no top soil worthy of the name under all that ice. Same with when people yuk it up with, "we'll just farm Canada!" Have you seen the dirt in British Columbia? I don't think that soil could grow anything other than more dirt. (Though Manitoba and Saskatchewan would probably do better, dunno.)

You don't know what you are talking about. Some of the richest soil exists in the Canadian North. I have lived on a farm and planted and raised vegetables on a Canadian farm for multiple years.
