Jimmy: I really love Leonardo DiCaprio. In addition to being a great performing artist, he is sincere in his effort to champion the world environmental cause. And not only is he an excellent spokesman, he also walks the walk even to the point of flying commercial rather than by private jets. He ranks with Ed Begley Jr. and others who live by example, and that says something to me.

Other people don't get me as excited. Now I understand that artists, entertainers and world environmental leaders have different security needs and are often bound by this, but where does the line cross between a machiavellian end justifies the means soot-belching locomotive to environmental Shangri La compared to life by example? What is sincerity and what is sophistry? And does all of this help or undermine the cause? That's the topic of our discussion.
