If we apply natures rule of survival of the fittest to people living in first world countries vs those that live in third world countries; who do you think will survive in the case of some world wide disaster say like oil ran out next week. Personally I think that those in the 3rd world have a far greater potential to survive as they are far more accustomed to living without. Most people in the 1st world would die if they had to gather and find food to live. ??
