Science can inform individual preferences but cannot resolve environmental conflicts. Environmental goods and services, to the greatest extent possible, should be treated like other goods and services in the marketplace. People should be free to secure their preferences about the consumption of environmental goods such as clean air or clean water regardless of whether some scientists think such preferences are legitimate or not. Likewise, people should be free, to the greatest extent possible, to make decisions consistent with their own risk tolerances regardless of scientific or even public opinion.
