This is just plain wrong. I have been writing about Tides for over two years. The Tides Foundation was organized in 1976. They are primarily funded by the Pew Charitable Trusts (Sunoco money).
NRDC was organized in 1970, predating Tides, and is far more influential. NRDC doesn't need organizational help from anybody.
GreenPIECE was founded in 1971, also predating Tides. They don't need Tides to money or organizational help to survive either.
The Union of Concerned Scientists was founded in 1969, also predating Tides.
EWG and the Ruckus Society are Tides projects.
Get your facts straight before posting, please.
