"[I]n nature, animals suffer a lot. They are constantly in search of food; they are little protected from extreme climatic situations; they do not receive any medical assistance if they are injured or sick; they are regularly attacked by other wild animals; And so on. Moreover, almost all animals brought into the world die before they can reproduce. It is indeed necessary to realize that a population remains stable if, on average, each animal gives life to a descendant which can also reproduce. The fact that the animals that do reproduce give birth to tens, hundreds, or even many more descendants means that very few survive. This massacre shows how trying the conditions in which they live are. Certain antispeciesists therefore believe that, faced with this situation, we should try to find ways of relieving wild animals of the evils that overwhelm them."
