Action Without Borders
A great organization that supports people's passions and promotes collaboration is called Action Without Borders and they run Idealist.org.
Here is their vision and mission (from their website):
We would like to live in a world where:
All people can lead free and dignified lives.
Every person who wants to help another has the ability to do so.
No opportunities for action or collaboration are missed or wasted.
Idealist connects people, organizations, and resources to help build a world where all people can live free and dignified lives.
Idealist is independent of any government, political ideology, or religious creed. Our work is guided by the common desire of our members and supporters to find practical solutions to social and environmental problems, in a spirit of generosity and mutual respect.
Action Without Borders has a lot of similarities with White Root Media and is one of my favorite nonprofits. Visit their website to learn more.
