Defending Wal-Mart

Yeah, Wal-Mart has problems. But sometimes they're worth defending. First, there's this story (which admittedly sounds more like a press release) about Wal-Mart switching to corn-based plastic for their packaging instead of petroleum-based plastic. Sounds pretty win-win to me. I just hope the corn-based plastic isn't subsidized, but I'm sure it is somewhere along the supply chain. So it's not the best story ever, but it's better than nothing.
