My friend Anna sent me this:
"bill gates' foundation invests their billions and billions in companies like dow chemical whose factories are literally killing people kilometers away fromwhere there are gates-funded clinics and ngo's. SO DUMB. it made me call my investor guy and switch all my meager holdings immediately to socially responsible funds, where i suppose they should have been in the first place, but anyway it goes right to the heart of the problem. the next one in the series was about warren buffett's money and its sleazy connections - to darfur-funding chinese petrol companies. great! party on, wayne. party on, garth."
Check the articles. They're a bit long, but they make a fascinating read.
