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