" Gardening is like cooking. It is tempting to cook only with the goal of achieving great taste, with no thought of healthy eating, but that often results in tasty concoctions so full of fat, sugar, and salt that they are deadly in the long run. Similarly, it is tempting to garden only for beauty, without regard to the many ecological roles our landscapes must perform. All too often, such narrow gardening goals result in a landscape so low in ecological function that it drains the vitality from the surrounding ecosystem. "
