Its rules are evolving, as Mr. Beavan will tell you, but to date include eating only food (organically) grown within a 250-mile radius of Manhattan; (mostly) no shopping for anything except said food; producing no trash (except compost, see above); using no paper; and, most intriguingly, using no carbon-fueled transportation.
Toothpaste is baking soda (a box makes trash, to be sure, but of a better quality than a metal tube), but Ms. Conlin is still wearing the lipstick she gets from a friend who works at Lancôme, as well as moisturizers from Fresh and Kiehl’s. When the bottles, tubes and jars are empty, Mr. Beavan has promised her homemade, rules-appropriate substitutes. (Nothing is a substitute for toilet paper, by the way; think of bowls of water and lots of air drying.)
Eeeuuuw! Me, I like to get the thickest toilet paper imaginable--and the biggest rolls. Have you seen these? They're the size of wagon wheels.
