Whole Foods shoppers probably noticed the store's countdown to Earth Day, when the chain's 270 stores stopped offering its customers plastic bags. The plan's a no-brainer for the grocers—they get green cred and endless retail opportunities (remember the Anya Hindmarch mania?) Lauren Bush, she of the ubiquitous burlap red-carpet accessory, is providing one such opportunity in the form of a (soon to be really ubiquitous) collapsible cotton-and-burlap (what else?) Feed 100 tote, available May 1. Bags are $29.99, which may seem steep, but each one sold buys 100 school meals for kids through the UN World Food Program. Now as long as Ms. Bush stops carrying her other feed bag everywhere, we'll all benefit.
