I became a vegetarian 55 years ago, and I think it's one of the more important behavioral changes I ever took. The more I see of the beef industry and so on, I believe that to be true.

So, you could call me optimistic and hopeful and probably just a little bit naïve, but I'm coming from the space that the best way to predict the future is to get out there and just do it yourself.

Any prudent business looks at the reality and how to maximize our investment.

I'm part of the consumer culture. I was part of the baby boom generation. I have a car when I shouldn't, a couple of computers; I can't be anti-consumerist in that sense.

The biggest weakness of the green-consumer movement, always, is that we tend to pick the easy-to-do things because that's where we can most readily engage people. It doesn't cost them very much to switch products or whatever it happens to be.

I think consumerism breeds dissatisfaction, and I think that the advertisers play to that. So I cannot be comfortable with that. On the other hand, the cornucopia of products and innovation - I love Apple, for example. That's a temple of consumerism in many ways.
