The Clean Water Act and the Clean Air Act are early examples of sweeping legislation that only a dedicated environmental agency could properly oversee.

The Aspen Institute, a nonprofit dedicated to fostering leadership and dialogue on wide range of topics, recently unveiled a list of "10 ways the U.S. Environmental Protection Agency has strengthened America over the past 40 years."
The home runs on the list--which was compiled by a group of more than 20 environmental leaders, including several former EPA officials--include: banning the widespread use of the pesticide DDT, which was decimating bald eagles and other birds and threatening public health; achieving significant reductions in sulfur dioxide and nitrogen oxide emissions that were polluting water sources via...
