This Week in GOOD

Hello. Did you know that tomorrow is National Public Lands Day, the nation's largest hands-on volunteer effort to improve and protect public lands? Well you do now. If you're in the Los Angeles area, for example, then you can participate in an effort to clean up spots near (though not in, because that's not safe yet) the recently fire-damaged areas of the Angeles National Forest. Great stuff.This week, we launched an exploration of how to use technology to improve our cities, learned about canned food, pondered solutions for fixing elections in Afghanistan, scoffed at Dan Brown, checked in on the G-20, and did a whole lot more. Don't forget to send submissions for our new contest by September 30.Photo: Quiksilver paddle-boarder and big wave surfer Jamie Mitchell meets a humpback whale. Courtesy of Liam O'Brien / Jason Muir.
