They have chapters in: New York, Austin, Canada, Portland (of course) and Twin Cities.
Here is a bit of their mission statement:
"Worldchanging was founded on the idea that real solutions already exist for building the future we want. it's just a matter of grabbing hold and getting moving."
Its about finding real solutions to cleaning up our environment and living a more sustainable way...like riding a bike...duh.
Lifetime artist, environmentalist and local community activist Wendy Brawer had this to say about biking in NYC
"It's November 1, 3:30 pm and I'm about to get on my bike and ride uptown. At 67 degrees, it's a perfect day for biking - not (just) for my personal comfort, but the shock of the warmth reminds us that the city should be doing all it can to encourage more bicycling everyday. NYC's sustainability plan inexplicably does not seem make non-polluting mobility a priority, despite our low air quality/high asthma rates, our perfect flat tight terrain for cycling and the growing number of people of all ages and backgrounds on two wheels in any weather."
