In the following two sections, Johannsen asserts that humans have a collective obligation to intervene in nature to reduce the suffering of wild animals and evaluates the risks associated with intervention.

A symposium was held on the book in April 2021, hosted by Animals in Philosophy, Politics, Law, and Ethics (APPLE) at Queens University, featuring commentaries by Nicolas Delon, Bob Fischer, Gary O'Brien, and Clare Palmer.

The second aspect acknowledges Johannsen's perspective on the balance between lives with positive and negative outcomes, but refutes the notion that this leads to his desired conclusion due to separate justifications.

He argues that large scale interventions in nature will, in turn, change the types of animals that will come into existence and, as a result, enable harms experienced by and inflicted by these individuals.

Furthermore, Johannsen addresses the concept of identity-affecting actions and the potential generation of secondary duties, extending considerations of rectificatory justice to interventions aimed at mitigating harm to wild animals.

[7] Elizabeth Mullineaux describes the book positively, asserting that it presents well-reasoned arguments that are accessible to readers regardless of their background in philosophy, ethics, or animal welfare and contending that the book offers a blend of agreeable insights and thought-provoking ideas, fostering a deeper understanding of wild animal suffering alleviation strategies and warranting a strong recommendation for readers interested in the subject.
