In Zoopolis, Donaldson and Kymlicka argue that intervention in nature to aid animals is sometimes permissible, and in some cases obligatory, to save them from the harms they commonly face. But they claim these interventions must have some limits, since they could otherwise disrupt the structure of the communities wild animals form, which should be respected as sovereign ones. These claims are based on the widespread assumption that ecosystemic processes ensure that animals have good lives in nature. However, this assumption is, unfortunately, totally unrealistic. Most animals are r-strategists who die in pain shortly after coming into existence, and those who make it to maturity commonly suffer terrible harms too. In addition, most animals do not form the political communities Zoopolis describes. The situation of animals in the wild can therefore be considered analogous to one of humanitarian catastrophe, or to that of irretrievably failed states. It matches closely what a Hobbesian state of nature would be like. This means that intervention in nature to aid nonhuman animals should not be limited as Donaldson and Kymlicka argue.
