Examining the oyster is an accessible way to take on the issue of urban development. Even though I'm from New England, I never wanted to eat cod that much. Oysters are much better.

One of humankind's most enduring misconceptions is that of nature's bounty... the belief that nature is such a powerful force that it is indestructible.

Man wants to see nature and evolution as separate from human activities. There is a natural world, and there is man. But man also belongs to the natural world. If he is a ferocious predator, that too is part of evolution. If cod and haddock and other species cannot survive because man kills them, something more adaptable will take their place. Nature, the ultimate pragmatist, doggedly searches for something that works. But as the cockroach demonstrates, what works best in nature does not always appeal to us.

Even though various groups hold very different attitudes, it's important to all sides. It's an issue that can cut both ways.
