My position is this. If we can't protect sanctuaries, if we can't save the whales, the sharks, the fish, our oceans will die.

What we need now is heroes - millions of them. Sentiment without action is the ruin of the soul.

It's funny but when young people say to me "what can I study to be a force for change, should I study law or biology or business?" My answer is music, drama, journalism, communications.

I can't think of a greater legacy than, "Because you lived, another species survived."

If you don't know an answer, a fact, a statistic - make it up on the spot.

I reject the idea that humans are superior to other life forms. . . Man is just an ape with an overly developed sense of superiority.

Be a voice for the future and a voice for the planet.
