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.

The ocean is the only alien and potentially hostile environment on the planet into which we tend to venture without thinking about the animals that live there, how they behave, how they support themselves, and how they perceive us. I know of no one who would set off into the jungles of Malaysia armed only with a bathing suit, a tube of suntan cream, and a book, and yet that's precisely how we approach the oceans.

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.

Oceanography is a terrific career because gradually we seem to be coming around to realize that we had better become as acquainted with the seventy percent of our planet that is covered by water as we are with the dark side of the moon.

Sharks don't target human beings, and they certainly don't hold grudges.

The great fish moved silently through the night water.
