In this Newsweek piece, Sharon Begly advocates collective action and legislation for environmental responsibility instead of just feeling nice after buying a Prius:
…We reduced acid rain by restricting industry’s sulfur emissions, not by all going out and sprinkling bicarb on sensitive forests and lakes. Leaded gasoline was banned by the Environmental Protection Agency in 1996, not by everyone choosing to buy cars that run on unleaded. Ozone-chomping CFCs were banned by the 1987 Montreal Protocol, not by everyone deciding to forgo spray cans and air conditioning.
The gases had to be banned, people. All environmental progress has come through national- and international-level regulation—to be blunt, by forcing people and industry to stop doing environmentally bad things and start doing environmentally good things, not by relying on individuals’ green good will or even the power of the marketplace.
