I love our planet as much as the next person, but I despise efforts by companies and people to get credit for caring about the earth with empty gestures. Like Pepsi's ridiculous Aquafina press stunt . Or all this black screen Earth Day nonsense . Or bringing in goats to eat your lawn . Or banning black cars . But I can't find anything wrong with Frito Lay's creation of a 100% biodegradable bag for SunChips. It will completely compost in 14 weeks under ideal conditions. I can imagine a day when most of our trash goes into our own back yard, simply to melt away into the ground.
