Economic Growth-The Essence of Sustainable Development
Anderson, Terry L., Huggins, Laura E., Reason
Thirty years ago, a group of academics known as the Club of Rome put forth the "limits to growth" theory, predicting disaster for humankind unless natural resource--depleting economic and technological progress were abandoned. This gloom-and-doom theory has been resurrected under the guise of sustainable development, calling for changes in virtually every aspect of our consumption and production.
"Sustainability," a seductive though vague term, argues that resource use today should leave future generations at least as well off as current generations. Of course nobody wants to make future generations poorer and less healthy, but this definition provides no guidance for how this result can be avoided. There is no way to know what resource use is acceptable today and no way to know what future generations may desire. Yet because of its deceptive simplicity, sustainability is applied to anything from agricultural practices to energy use to mining.
Implicit in the calls for sustainable development are two fundamental assumptions. The first is that we are running out of resources, thus leaving future generations with less; the second is that market processes are the cause of these depletions. But in fact, several studies offer evidence suggesting the opposite.
Resources are becoming less, not more, scarce. Agricultural yields for rice, corn, and wheat have increased for decades. Known reserves of oil, natural gas, and coal have been expanding, and accessible stocks of aluminum, zinc, iron, and copper have grown as technology develops more-conservative production techniques and the price mechanism encourages exploration and new discoveries of underground reserves. Moreover, life expectancy, housing, nutrition, and education levels are improving in both the developed and the developing world. In short, the prosperity we enjoy today is leaving future generations better off, not worse off. …
