Georges-Louis Leclerc, Comte de Buffon on Wild animal suffering

“Born to destroy those beings which are subordinate, we should exhaust Nature if she were not exhaustless, and by a fertility superior to our depredations, renovates the destruction we continually make. But it is so ordained that death should contribute to life, and that reproduction should spring from destruction. However groat, therefore, may be the waste made by man and carnivorous animals, the total quantity of living matter is never diminished, and if they hasten deaths they are also the cause of new births being produced.”

“The stag, and most wild animals ... who suffer much from want in the winter, have no superabundance, nor are in a state to engender till they have recruited themselves during the summer; and it is then the rutting season commences, and during which he exhausts himself so much that he remains the whole winter in a state of langour. His flesh and blood are then so impoverished that worms breed under his skin, which still adds to his misery; and which do not perish till the spring, when he recovers new life from the active nourishment he is abundantly furnished with by the fresh production of the earth.”

“Plants are only reproduced once a year, whereas in insects, especially among the smaller species, one season gives birth to several generations. Among insects there are numbers who live upon other insects; there are some, as the spiders, which devour with indifference their own as well as other species; they serve for food to the birds; and fowls, both wild and tame, are destined for the nourishment of man, or the prey of carnivorous animals. Thus violent deaths seem to be equally as necessary as natural ones; they are both modes of destruction and renovation; the one serves to preserve nature in a perpetual spring, and the other maintains the order of her productions, and limits the number of each species.”

“Let us consider any of the inferior species which serve as food to others, herrings, for example, present themselves in millions to our fishermen, and after having fed all the monsters of the northern sea, they contribute to the subsistence of all the nations in Europe for a certain part of the year. If prodigious numbers of them were not destroyed, what would be the effects of their prodigious multiplication? By them alone would the whole surface of the sea be covered. But their numbers would soon prove a nuisance, they would corrupt and destroy each other. For want of sufficient nourishment their fecundity would diminish, by contagion and famine they would be equally destroyed, the number of their own species would not be increased, but the number of those that feed upon them would be diminished. As this remark is alike applicable to any other species, so it is necessary they should prey upon each other, the killing of animals, therefore, is both a lawful and innocent custom, since it is founded in nature, and it is upon that seemingly hard condition they are brought into existence.”
