Humans often intervene in the wild for anthropocentric or environmental reasons. An example of such interventions is the reintroduction of wolves in places where they no longer live in order to create what has been called an “ecology of fear”, which is being currently discussed in places such as Scotland. In the first part of this paper I discuss the reasons for this measure and argue that they are not compatible with a nonspeciesist approach. Then, I claim that if we abandon a speciesist viewpoint we should change completely the way in which we should intervene in nature. Rather than intervening for environmental or anthropocentric reasons, we should do it in order to reduce the harms that nonhuman animals suffer. This conflicts significantly with some fundamental environmental ideals whose defence is not compatible with the consideration of the interests of nonhuman animals.
