More Of The "Now How Green Is This?" Puzzle

As I've noted here before, like many people, I do my bit for the environment, but like many people, I often wonder: What's "right"? You know: The plastic v. paper puzzle.

Anyway, on that subject, two puzzlers for you to ponder.

First from The Green Lantern at Big Money on the rent-film-by-mail v. drive-to-video-store.

Second, cogent reflections from the always-cogent Patrick Emerson at the Oregon Economics Blog, in which he ponders a worthy question: whose cleaning products should he buy? Ones from the politically correct company, or from the non-PC company with bigger clout? (Patrick, by the way, violates my no-black-background rule, but I love what he does, so -- he gets a pass.)
