i had never seen anything like that, couldn't even imagine it except in maxfield parrish storybooks. but there it was: this unbelievable view, this pure view that nature carved itself. and i thought, "i just can't believe this." and it wasn't that i was looking at it like a postcard. i went beyond that; i went to the point of, "i have to be a part of it. i just want to be a part of this." and that was an impulse when i was 11, and that began something that grew and grew into what eventually became a very active concern for the environment. you know, we had harry belafonte here not long ago, and it was interesting to hear him talk about how the causes he believed in and the culture he pursued-- his work-- initially were not combined, but they grew together in a way that he began to make career choices that were based on his beliefs. as a young actor, you would not have had that option early on. you did television shows, twilight zones, guest appearances. at what point did you recognize that you had enough star appeal, enough clout to begin to make choices that reflected your values? w
