John Renesch (I see this post may register as anonymous and I do not know what to do so I am identfying myself here.
I recommend www.WiserEarth.org as a resource for finding organizations and people who are activists attempting to correct critical global issues…collectively what its founder Paul Hawken likens to the world's immune system. You can search by issue or name…last time I checked they had well over 10,000 orgs.
reIt could be the largest directory of global organizations dealing with global issues and, therefore, a place to check to see if you'd be reinventing the wheel. I am a big believer in working together whenever possible as opposed to starting a similar project that competes (for funding, volunteers, etc.). If an issue isn't getting attention and it warrants it, then VOILA! Start one…like the think tank of global transformationalists I'm in the process of starting.
The issues we will be covering (the starting list) includes:
Climate
Commerce/business
Consciousness/thought process
Economics
Education
Energy
Environment/sustainability
Future scenarios
Gender relations
Governance
Human Relations
International Relations
Media and Communications
Social Justice
Systems Dynamics
Youth
