Air America put together a list of companies that you should think twice about before handing them your money. Their research is based on descriptions from The Blue Pages: A Directory of Companies Rated By Their Politics And Practices. This is a super handy little book that tells you about companies' environmental, human rights and labor practices and also which political parties they give money to and how much. There are probably hundreds of '10 worst' (or best) lists you could come up with from the book, but Air America at least got the ball rolling.
