These parameters are probably not linearly related.  If the population
in Burma continues to grow at its current rate, it is likely that per
capita consumption will decrease since their economy does not generate
the wealth to increase consumption at that rate.  Although poor
countries may have increasing GNP's per capita, physical consumption
tends to decrease with large population growth rates.

I do think that biodiversity problems are concentrated in these
countrues.  Part of this is due to presures to supply exports to
consumptiojn in the developed countries but I do not know how this
component compares to that driven by poverty.

I agree that it is incorrect but I was not aware that it is common.
It isn't among the people I know.  There is a "fond" attitude about
low-teck lifestyles, but I wasn't aware that they were tied to
continuing population growth.

If per capita consumption is kept constant, that would be true.  I don't
think that that is the case, however.
