If you can, catch the series The New Heroes on PBS, which profiles "social entrepreneurs" -- individuals who've taken the initiative to create positive change in their communities and societies. I saw the first installment, and it was very heartening. It profiled Kailash Satyarthi, an activist fighting industrial slavery in India, both by rescuing slaves and by marketing Fair Trade Indian rugs; Mimi Silbert of the Delancey Street Foundation in San Francisco, which helps ex-cons, ex-addicts and others learn marketable skills and regain a sense of dignity and competence; and Zambian Moses Zulu, who is creating a self-sustaining village for AIDS orphans.
As someone who finds myself frequently angered and frustrated by the utter crap -- the constant fluff, fear-mongering and PR churnout posing as journalism -- presented in the American media, this program was like a breath of fresh air. Check it out. You'll feel happier for having watched these programs.
