Earth Day is today. I know this because Google’s logo has been decked out in leafy greens, because Whole Foods, not content to celebrate a mere day, is celebrating Earth Month in both its stores and on its website, and because, in the last few hours, I’ve received emails from both Best Buy and Crate and Barrel advertising Earth Day-related specials. On one hand, kudos to America’s mid-level luxury brands for their ability to fold absolutely anything into their advertising message. On the other hand, I continue to be amused by the way environmentalism, in mass practice, tends to express itself primarily through retail consumption.
