The Green Gate had its origin in frustration. Staff members at NRDC's San Francisco office were having trouble finding information about the Bay Area's environment. No comprehensive information source seemed to exist, and the materials we did turn up often provided fragments of the story rather than the whole. If professional environmentalists were having a hard time piecing together a picture of our area's environment, we concluded, other concerned citizens were probably stymied, too.

So NRDC decided to gather this data ourselves, and present it in a website, along with information to help users act on what they learned. The Green Gate is the result. Here you'll find a wealth of information on the health of the San Francisco Bay Area environment -- about air and water quality, wildlife, energy use, population trends, even the voting patterns of our government representatives. The site brings together information on environmental "indicators" in five categories (air, water, wildlife, urban living, and health). It tells you the basic facts, explains recent trends, suggests steps for protecting our natural resources, provides links for more information, reviews fiction and nonfiction about the region, and offers advice on ways to get outside and enjoy the Bay Area's many natural wonders. The Green Gate covers the nine counties of the San Francisco Bay Area: Alameda, Contra Costa, Marin, Napa, San Francisco, San Mateo, Santa Clara, Solano, Sonoma.

About NRDC
The Green Gate is a project of NRDC, the Natural Resources Defense Council. NRDC uses law, science, and the support of 1.2 million members and online activists nationwide to protect the planet's wildlife and wild places and to ensure a safe and healthy environment. For more than three decades, NRDC lawyers, scientists and other environmental experts in our San Francisco office have been working to protect the Bay-Delta ecosystem, improve the Bay Area's water and air quality, limit oil development in the region and encourage energy conservation. NRDC staff have also attacked pesticide use, myriad threats to children's health and many environmental issues beyond the Bay Area and California.
