Reading this again, I was wondering if perhaps a shorter statement might be more purposeful, and allow wiggle-room...  like, "Helping make the Upper East Side more environmental sustainable by bringing together a community of neighbors interested in positive improvements to our neighborhood's relationship with the environment."

Just thinking in terms of brevity & avoiding negative, scolding-like connotations, but I'm just a hack.  Maybe the question of a mission statement would make a nice ice-breaker at the first Upper Green Side meeting :)

Off-topic, I'm reading a new book by Kim Stanley Robinson, Fifty Degrees Below, which you and other peak oil/global warming interested people might enjoy... it's science fiction, the second book in a trilogy about science and politics, in which global warming causes abrupt climate change.  Washington DC gets flooded, animals are freed from the zoo for their safety... it's beautiful.

Yeah, I like that. Someone else emailed me that they like the idea of promoting "positive" impact instead of curbing negative impact.

I've applied for a few grants through another organization and they seemed pretty hopeful that it would work out. If so, we might have some $$$ to spend on a membership drive and community survey of environmental issues.
