What do cork, coffee cups, lettuce, and excessive travel have in common? They are all areas of personal choice that have an environmental impact, and they are all things we discuss with our guest on Sea Change Radio. Lloyd Alter is a design professor as well as an editor at TreeHugger.com. On this edition of Sea Change Radio, he expounds on the virtues of cork, a surprisingly sustainable alternative to fossil-fuel-based products for sound-proofing, insulation, home-building, and, of course, bottling wine. We also talk about the waste generated by ubiquitous coffee-to-go, the diminishing need for travel in the era of electronic communication, and what Alter posits to be the idiocy of lettuce.
