In this paper, following the taxonomy developed by Mackenzie, Rogers and Dodds of different sources and states of vulnerability, I claim that wild animals are inherently and situationally vulnerable. This is because they can experience suffering as a response to certain internal and external states and have a high exposure to, and a low capacity to cope with, harmful natural processes. From this it follows that we have a moral obligation to support and assist individuals who are occurrently vulnerable and (...) to reduce the risk of dispositional vulnerabilities becoming occurrent in the future, by endorsing some form of what I call ‘environmental enhancement’. Finally, I pay critical attention to how to prevent interventions aimed at ameliorating vulnerability from paradoxically generating pathogenic vulnerabilities. (shrink)
