If man doesn't learn to treat the oceans and the rain forest with respect, man will become extinct.

Look, Chief, you can't go off half-cocked looking for vengeance against a fish. That shark isn't evil. It's not a murderer. It's just obeying its own instincts. Trying to get retribution against a fish is crazy.

Just when you thought it was safe to go back in the water.

There's nothing in the sea this fish would fear. Other fish run from bigger things. That's their instinct. But this fish doesn't run from anything. He doesn't fear.

I guess I'm a hopeful optimist, because to be a pessimist is to be suicidal.

Without sharks, you take away the apex predator of the ocean, and you destroy the entire food chain

Without the oceans there would be no life on Earth.
