In the UK there's "Ethical Consumer" which is a magazine and website. They cover a broad range of ethical issues people are interested in (for example, I might care that meat is free range, but not care at all if it's organic or not).<p><a href="http://www.ethicalconsumer.org/" rel="nofollow">http://www.ethicalconsumer.org/</a>
I don't think you should let an organization do your own thinking. Sometimes when you dig a little you find that the situation is not black and white and that a boycott is not right or an ethical product is not that ethic after all.
