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.

Behavioral change is more important than individual product choices. They both have a role to play.

I'm worried about greenwashing. I think we should come down on it very, very hard, whether it's with criminal intent or actively deceptive.

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.

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.
