- I don't think that these numbers are actually typical of Burma btw. I was just
- going with the example provided.
-
- But it is hard to imagine impact declining steeply enough to outweigh
- rapid growth rates. (see my concluding paragraph below)

- Ask around among your Environmentally Correct friends. You will find many
- of them making the specious argument that because overconsumption exists
- in the west, therefore overpopulation is not a serious problem. I believe
- they make this statement because they are Politically Correct in other ways,
- and are loathe to find fault with any culture other than their own.

- If per capita consumption does not decrease exponentially at a rate faster
- than the exponential growth rate of the population, it remains true. I
- recommend the arithmetic exercise to anyone unconvinced.
