Climate change is critical to me because I'm a parent; I feel a sense of responsibility to the future. I'm not going to be around to see its worst effects, which are going to be hitting in the 2030s, '40s, '50s, but my kids will.

Hope is not a strategy. Luck is not a factor. Fear is not an option.

I lived in a small town. It was 2,000 people in Canada. A little river that went through it and we swam in the - you know, there was a lot of water around. Niagara Falls was about four or five miles away.

I had read tons of science fiction. I was fascinated by other worlds, other environments. For me, it was fantasy, but it was not fantasy in the sense of pure escapism.

So my message is in whichever realm, be it going into space or going into the deep sea, you have to balance the yin and yang of caution and boldness, risk aversion and risk taking, fear and fearlessness. No great accomplishment takes place, whether it be a movie or a deep ocean expedition, or a space mission, without a kind of dynamic equipoise between the two. Luck is not a factor. Hope is not a strategy. Fear is not an option.
