http://fairtradeusa.org/ "We help farmers in developing countries build sustainable businesses that positively influence their communities. We're a nonprofit, but we don't do charity. Instead, we teach disadvantaged communities how to use the free market to their advantage. With Fair Trade USA, the money you spend on day-to-day goods can improve an entire community’s day-to-day lives." Certified Fair Trade products (like chocolate) help prevent the use of slave labor as well.
