In my Earth science classes, we talk about "heal(ing) the split between what you think and what you do" (from Michael Pollan's article, Why Bother) as it relates to climate change and environmental issues, but this really applies to all areas of life. I try to encourage students to find an issue that they care about and take some small step to make a positive impact on that issue, to make what they do match what they think.
I heard a great example of this today on NPR, a company called Gideon's Shoes in Australia (which as a side note has had a roaring economy recently). Gideon's Shoes was started as a profit creator to benefit a set of youth centers called The Street University for underserved areas of Sydney where young people can come to play basketball, rap, and "...realise their own innate capacity as well as their ability to affect change and to participate in the community around them." They designed some sneakers and explored their manufacturing options in Asia, but found poor working conditions in all of the sweatshops they visited, so instead they decided to have their shoes manufactured in Australia with decently paid workers and good working conditions. As a result, their shoes are a bit more expensive than some mass-marketed, mass-produced shoes, but the profits go to good working conditions and a great youth center cause. Their shoes are also made with Australian products like kangaroo leather and cane toad hide and they look sweet. If I had $170 to spend on shoes, I would absolutely get a pair of these in gold. What a sweet work shoe!
