We need some regulation. Even the most bombastic conservatives recognize this. So everyone also should recognize that when President Obama says the GOP favors "dirtier air [and] dirtier water," he is committing the fallacy of the false alternative. The political dispute is not whether to regulate, but how much, writes A. Barton Hinkle. Everyone also can agree that if an environmental rule can prevent 1 million birth defects at a cost of only one dollar, then the regulation merits adoption—and if a regulation would prevent only one birth defect at a cost of $100 trillion, then it does not. In the real world regulations fall within narrower parameters.
