It hasn't changed my life, but it made me a little more mindful of my impact - a story in Bitter Chocolate tells of the problem with banning the products of child labour in the garment industry (which I had always thought was the solution - just don't import it), and how the children were all sacked and then had to be prostitutes and work rock crushing (and a lot then died, as the work is dangerous). So it's left me thinking, and mindful when in the shopping aisles...
