Probably familiar to many here, maybe new to some...

First of all, being a city dweller, I'm very inspired by Kevin Danaher's vision for a global citizen center. I believe this is the kind of urban synergy that can help shape a sustainable future. Check it out & watch the video!

Suprisingly, I don't recall seeing mention of Bioneers here on this tribe. Maybe I just missed it. It's an important hub of eco-pioneers. I'm excited that the big event will be beamed into Seattle this year, just a couple weeks away.

Another very important networking hub is Wiser Earth.
