The Environmental Defense Fund opened an office near Walmart's headquarters in Bentonville, Ark., 10 years ago. It was part of a carefully plotted strategy to persuade the giant retailer that going green could be good for business. If it worked, it certainly could be good for the planet — Walmart's revenues are bigger than the entire economy of most countries.
