"Although disease and suffering in animals are unpleasant and, perhaps, regrettable, biologists recognize that conservation is engaged in the protection of the integrity and continuity of natural processes, not the welfare of individuals. At the population level, the important processes are ultimately genetic and evolutionary because these maintain the potential for continued existence. Evolution, as it occurs in nature, could not proceed without the suffering inseparable from hunger, disease, and predation. For this reason, biologists often overcome their emotional identification with individual victims. For example, the biologist sees the abandoned fledgling or the wounded rabbit as part of the process of natural selection and is not deceived that "rescuing" sick, abandoned, or maimed individuals is serving the species or the cause of conservation. (Salvaging a debilitated individual from a very small population would be an exception, assuming it might eventually contribute to the gene pool.) Therefore, the ethical imperative to conserve species diversity is distinct from any societal norms about the value or the welfare of individual animals or plants. This does not in any way detract from ethical systems that provide behavioral guidance for humans on appropriate relationships with individuals from other species, especially when the callous behavior of humans causes animals to suffer unnecessarily. Conservation and animal welfare, however, are conceptually distinct, and they should remain politically separate."

"The chief activities of beings, both human and non-human, are put forth, directly or indirectly, for the purpose of procuring food. The suppression, entire or partial, of one being by another for nutritive purposes is, therefore, the form of the most frequent and excessive egoism. The lowly forms of life—the worms, echinoderms, mollusks, and the like—are, for the most part, vegetarians. So, also, are prevalently the insects, birds, rodents, and ungulates. These creatures are not, as a rule, aggressively harmful to each other, chiefly indifferent. But upon these inoffensive races feed with remorseless maw the reptilia, the insectivora, and the carnivora. These being-eaters cause to the earth-world its bloodiest experiences. It is their nature (established organically by long selection, or, as in the case of man, acquired tentatively) to subsist, not on the kingdom of the plant, the natural and primal storehouse of animal energy, but on the skeletons and sensibilities of their neighbors and friends. The serpent dines on the sparrow and the sparrow ingulfs the gnat; the tiger slays the jungle-fowl and the coyote plunders the lamb; the seal subsists on fish and the ursus maritimus subsists on seal; the ant enslaves the aphidae and man eats and enslaves what can not get away from him. Life riots on life—tooth and talon, beak and paw. It is a sickening contemplation, but life everywhere, in its aspect of activity, is largely made up of the struggle by one being against another for existence—of the effort by one being to circumvent, subjugate, or destroy another, and of the counter effort to reciprocate or escape."
