The teens are part of the Greenagers program, which helps ninth and tenth-graders in San Francisco connect with wildlife and nature. The kids are interviewed and selected for the program, even earning a small stipend. They do a variety of cleanup efforts in their own neighborhoods. Today they are picking up trash and clearing brush away from the trail.
Disney, the parent company of ABC7, awarded a $20,000 grant to the program.
