Actually, I think this is a conversation that needs to happen here--both
because ecologists need to be engaged in this discussion, and because a truly
ecological perspective is sorely missing from the population debate.
May I submit that, from a process-function view, that population is not the big
problem for planetary carrying capacity--rather we need to be watching
consumption and pollution, and that includes GHG emissions.
Ehrlich and Holdren and Commoner gave us I=P*A*T. As a life-long Third
Worlder, I would suggest there are real reasons why population cannot be the
wedge we use to get at carrying capacity. But at least, read Kates,
Population, Technology and the Human Environment: A Thread Through Time.
I'm sure we have a carrying capacity problem. But a sustainability frame
includes equity. Making this about population puts the problem of carrying
capacity on the shoulders of the Third World. In effect, we externalize the
problem onto "them," and can then sit back and enjoy the "fruits of Western
Civilization" for ourselves. Making this about consumption, and to some extent
about pollution, puts the problem squarely where I believe it belongs, on us.
Think about it. The world population is at 6.7 billion (and most likely to
stabilize around nine billion). America has a population of 300 million and is
said to use 30% of the world's resources. India and China have a population of
over 2.5 billion, and they want what we got--mainly because we've spent decades
telling them that what we got is what they ought to want. Hollywood ensures
that the American "way of life" be the ideal that all civilizations shoot for,
in order to show that they too are modern.
Its roosting time, folks. Anything we can possibly do about population will
have a lag time of decades. Anything we do about consumption and pollution can
have immediate impacts. The choice is ours.
And yes, innovation, though taken differently than Julian Simon meant it, is
still the answer.
Cheers,
