What's Your Consumption Factor?

I missed this Jared Diamond op-ed in the New York Times earlier in the month about how consumption, not population, is the crucial factor when thinking about resource depletion. He gets it all more or less exactly right, especially when he explains how the last few years have finally put to bed the central lie of globalization, that the "rising tide" can or will lift all boats:

Per capita consumption rates in China are still about 11 times below ours, but let’s suppose they rise to our level. Let’s also make things easy by imagining that nothing else happens to increase world consumption — that is, no other country increases its consumption, all national populations (including China’s) remain unchanged and immigration ceases. China’s catching up alone would roughly double world consumption rates. Oil consumption would increase by 106 percent, for instance, and world metal consumption by 94 percent.

If India as well as China were to catch up, world consumption rates would triple. If the whole developing world were suddenly to catch up, world rates would increase elevenfold. It would be as if the world population ballooned to 72 billion people (retaining present consumption rates).

Some optimists claim that we could support a world with nine billion people. But I haven’t met anyone crazy enough to claim that we could support 72 billion. Yet we often promise developing countries that if they will only adopt good policies — for example, institute honest government and a free-market economy — they, too, will be able to enjoy a first-world lifestyle. This promise is impossible, a cruel hoax: we are having difficulty supporting a first-world lifestyle even now for only one billion people.

Diamond also has good things to say about the ways in which reducing consumption in the West need not be understood as an apocalyptic disaster, but as an opportunity for efficiency, simplicity, and even a better life:

Real sacrifice wouldn’t be required, however, because living standards are not tightly coupled to consumption rates. Much American consumption is wasteful and contributes little or nothing to quality of life. For example, per capita oil consumption in Western Europe is about half of ours, yet Western Europe’s standard of living is higher by any reasonable criterion, including life expectancy, health, infant mortality, access to medical care, financial security after retirement, vacation time, quality of public schools and support for the arts. Ask yourself whether Americans’ wasteful use of gasoline contributes positively to any of those measures.

More on this in the coming week, I'm sure...
