A couple of years ago, after sending my five-year-old daughter off to school, she came home reciting the same cheerful environmental mantra I was taught in elementary school.

"Reduce, reuse, recycle," she beamed, proud to show off a bit of rote learning.

The moral virtue of recycling is rarely questioned in the United States. It has been ingrained into the American psyche over several decades. On a recent trip to the Caribbean, my friend's wife exhibited nervous guilt while collecting empty soda, water, and beer bottles destined for the trash since our resort offered no recycling bins.

"I feel terrible throwing these into garbage," she said, wearing a pained look on her face.
