 The cases from the literature on letting oneself do harm may seem contrived. This may lead one to think that accounting for such cases is not a central issue for an account of the doing /allowing distinction. Charlotte Franziska Unruh (2021) argues that such cases of letting oneself do harm are merely a subset of cases involving complicated causal chains where the agent is relevant to harm in more than one way. Moreover, she argues, such cases arise frequently in cases involving future generations, for example, when we must make decisions about whether to mitigate climate change resulting from our past carbon dioxide emissions.
