Stop the Traffik
At a church service for Christian Aid Week last night, my attention was drawn to this organisation, which is a group of organisations campaigning for the abolition of present day slavery - people trafficking, sex trafficking, call it what you like. You can sign a pledge on their website (also available as a postcard, which you can order), and also find out more about children being trafficked to Cote d'Ivoire to work on cocoa plantations (for chocolate). A substantial proportion of cocoa for chocolate comes from Cote d'Ivoire.
The site is at www.stopthetraffik.org - sign the pledge, see if your organisation can sign up en bloc, and read about where to buy slavery-free chocolate.
