- This is sort of what I was getting at. I know that there is no single
- answer. The question "How many?" is tied to the question "How well
- will they live?" Clearly its not a simple, monotonic relationship.
- If human impact can only be reduced so far before reduced
- industrialization hinders efficient agriculture and food distribution,
- then there is some point at which reducing impact further will
- decrease the carrying capacity.
-
- I was just wondering if there is anything out there about what
- number/life-style options are realisticly available to choose from.
- Since the population is expected to be about 6 billion within the next
- few years I find it rather disconcerting that not much attention seems
- to be directed toward controlling the size of the human population.
- Perhaps becuase there are no clear ideas on size/quality tradeoffs with
- which to choose goals. It seems to me that many of the acute
- environmental problems are secondary to population loads.
