Going back to being a teenager, I'd roughly know how to plant some kinds of crops - but I really wouldn't know how many I'd be required to plant in order to live from one harvest to the next. (Though I guess this could be alleviated a bit if the kids got some of those mass-scale agricultural vehicles running for a bit, then they might be able to get too many crops for the first harvest, at least until fuel runs out). | |

In most of South-America it is the other way around. It is definetly not. You would remove more than 70% of the population of South America. For Brazil, by far the most populous country of the region, you would reduce the population from 200,000 to about 50,000 - by 75%. Indeed, I don't think it would be "the other way round" even in Subsaharian Africa or Southern Asia. | |
