Patricia Clarkson has joined celebrities like Robert Redford in decrying the Gulf oil spill and urging people to support the Natural Resources Defense Council in pressuring lawmakers to pass clean energy legislation.

The Louisiana native draws upon the memories of growing up close to the Gulf — and its relationship with the people — in a new PSA for the environmental organization.

"I remember the bay as a place filled with wildlife — birds, alligators, sea turtles, and of course abundant oyster, shrimp, and crab beds," she writes in a new blog entry promoting the video. "But since the BP explosion, the bay has become an industrial zone."

"Oil sheen covered the water as far as we could see, and in every single marsh we passed, it was as if someone had taken a giant brush, dipped it in a big bucket of paint and painted the grass black. We went over to Cat Island, where the pelicans gather. There was no place for them to land that was oil-free, so they touched down in oily water, and their bellies were covered with the stuff."

Clarkson then goes on to describe the Gulf's impact on the people who depend on a healthy ecosystem for their livelihoods — adding, "the spill is a wake-up call for all of us."
