Canada's relationship with Mexico

Another general thought seems to be that 'Indians' lived on meat or fish. No one can live on those alone. Just watch "Alone" and see how those folks make out!
Makes sense to grow your food and keep it handy, rather than traveling to go get it all the time.
Hope that helps. Cheers

As far as I know, the Eskimos on the North Slope of Alaska only survive on meat and fish, since nothing edible (for humans) grows at those latitudes. The caribou make do with what grows on the tundra.
