Recent atmospheric studies have shown that constantly increasing levels of carbon dioxide and other gases are capable of raising the earth's average temperature. Although no one is certain how serious global warming may become, the threat can no longer be ignored. The best way to reduce these gasesis to make consumers pay the full environmental costs of various energy sources. The greater the amount of pollution a given energy source generates, the higher the consumer price should be. In addition to curtailing the use of environmentally destructive power sources, a program based on such marketplace incentives would spur efforts to develop less harmful alternatives.
