“ Richard looked up at the beautiful, big pines spreading over them, illuminated in the firelight. A spark of understanding lit in his mind. He saw the branches stretched out with murderous intent in a years-long struggle to reach the sunlight and dispatch its neighbors with its shade. Success would give space for its offspring, many of which would also shrivel in the shade of the parent. Several close neighbors of the big pine were withered and weak, victims all. It was true. The design of nature was success by murder. ”
