We only have ten years to save the oceans

The environmental movement, like all political processes, reacts best to disasters. But these are very slow, very gradual disasters in the making.

I let my [past] life in peripherally, because I'm interested in what's over there; I want to keep going forward.

I was going through so many changes in my life - separation with my wife, having an affair - that was all very messy and public. It felt like if I really wanted to rock my boat and make changes in my life and who I am and how I am, that would also mean moving on from Cheers.

The biggest danger we face is overfishing. We literally could fish out our oceans, some scientists believe, in the next 40, 50, 60 years. We are fishing out the top of the food chain, and it's pretty crucial because about 200 million people depend on fish and fishing for their livelihood, and about a billion people, mostly in poorer countries, depend on fish for their protein. So this is a big problem. Good news is, it's fixable.
