Ken Adelman Corralitos, California Retired Internet entrepreneur and California coastline protector, age 39
"It started in 1996, when I made a call to the Sierra Club offering the use of our helicopter in the Clubs fight to protect the California coastline. My wife pilots while I take aerial photographs. One of the frustrating things early on was seeing something stupid that somebody had done and realizing it would have been nice to have a before picturebefore that part of the coast had been destroyed. But the only way we could get those photos was to shoot the entire coastline. Thats what weve done. The Web site we launched last year (www.californiacoastline.org) contains about 12,100 digital before pictures taken roughly every 500 feet.
"The only part of the coast weve not shot is a 50-mile stretch around Vandenberg Air Force Base. We cant get permission to fly over it. But were getting ready to begin the second round of photographs of areas weve already covered.
"Theres 1,100 miles of coastline in California. I divide it into three categories: North from San Francisco to the Oregon border is remote and basically not threatened. Then theres the urbanized coastline, especially from Santa Barbara to San Diego and also Santa Cruz, which has already been ruined. Finally, there are the in-between areas. Typically, these are under development right now, with housing and cities nearby expanding toward the coastline. These in-between areas are where we need to focus our conservation efforts.
"Our photos let the California Coastal Commission see whats happening. The commission frequently uses our photos for development decisions or enforcement action, since they bring truth to the process. Citizens use the photos to fight developments all along the coast.
"I do it because its my home, and I dont want to see people destroy it."
