Global Exchange has a classroom kit on educating children that other kids their age are slaving for their sweet tooth. as well as a list of certified free-trade chocolate companies.
You can also send a fax to M & M/MARS. I told them that I thought execs should take a small pay cut so families on the other side of the world can get a fair price for their cocoa. Oh that and I said that AMERICAN CHILDREN EAT CHOCOLATE TAINTED BY SLAVE LABOR AND DISEASED WORKING CONDITIONS.
Love that CAPS LOCK.
