Gus Speth: Well, you have to start with this paradox. The paradox is that we've got stronger, more sophisticated and the environment kept going downhill. And so you ask why has that happened. The things that we've been doing, have to do with raising public awareness about issues, developing really interesting well thought out proposals for dealing with these issues, lobbying to get them enacted into law, litigating to get the law effectively carried forward. So this is really working within the system. This says that the system will deliver. If we try hard enough, we work within the system, things will be fine, we'll eventually succeed. We're swimming upstream, but we'll get stronger and we'll prevail against the current. Turns out, that's not what's happened. We've certainly made some big improvements. The world would be a much more threatening place than it is today even without this environmental movement, so to speak. But we haven't succeeded, by and large, is my conclusion. And so you have to say, well, then we're up against a system that's condemning us to losing. We're playing a loser’s game and we have to ask, then, don't we need to challenge the system? Rather than always swimming upstream against that current, don't we need to ask what's making that current get stronger and stronger as we get stronger and stronger, so we're not making real progress, we're drifting away. And the system that we're operating in, in my book, I refer to, you know, put the label on it, it's today's capitalism. It's capitalism as we know it today. And we are not-- I think we are fundamentally incapable of prevailing against that system, so we need to change the system. Clearly, we don't try to find a socialist alternative to today's capitalism, but we do need to look for a non-socialist alternative to the capitalism that we have today. And the book is really an exploration of that alternative.
