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.

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.

What people say often precedes what they think. Some people sometimes say, "I have to hear myself talk before I know what I think." I think language sometimes, because it opens new channels, it opens new doors, is enormously important.

I think people often underestimate the power of consumers. But I equally say that consumers are like shock troops: You can't keep them agitated and motivated and committed and active forever. There are pulses where they switch on to a particular issue, and just inevitably they switch off.

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

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.

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.
