How do we motivate an economics that is consistent with a healthy environment? One way is to have the consumer pay the full unsubsidized ecological costs of his purchases. And you don't have to be a hairy anarchist to advocate this.

From a 2002 issue of Nature Conservancy Magazine.

At the 1992 Earth Summit in Rio de Jaeiro, the 48 founders of the World Business Council for Sustainable Development-among them chiefs of major U.S. firms, including 3M and Johnson & Johnson-urged political leaders to tax energy, stop subsidizing fossil fuels and move toward "full-cost pricing" of goods and services, making prices reflect the toll on natural resources.
