Wal-Mart has 
created a website to tell the English-speaking world the truth about itself. They've even purchased a sponsored area on Google, Yahoo, and Altavista to make sure everybody will visit their new site. I've looked around but haven't found anything on the third world or pollution, but they reassured us that they 
require all contractors to follow all laws. No comment on whether 
contractors in other countries are allowed to break laws.
