I've just discovered a magazine called Good, which in their words is "a collaboration of individuals, businesses, and nonprofits pushing the world forward." The articles focus on ways to keep moving forward, one step at a time, in making our world a better place to live.
A few weeks ago I linked to an article about a man in Sacramento who leads garden walks around urban areas -- he and his group pick the fruit that's ripe (with the home-owner's permission) and donate the harvest to local food banks. Good is running a similar article about people in a variety of areas all doing the same thing. The good idea is catching on!
