This collection investigates the evolving moral obligations humans hold toward non-human animals and the broader natural environment. Dale Jamieson, a prominent scholar in environmental ethics and bioethics, compiles twenty-two essays spanning three decades of academic inquiry. He argues that our current ethical frameworks are insufficient for addressing contemporary ecological crises and proposes a more inclusive moral philosophy that accounts for the intrinsic value of non-human entities.

Experts recognize this collection as a significant contribution to the field of environmental philosophy, noting its clarity and accessibility for both students and academics. Readers frequently highlight the author's ability to bridge complex theoretical debates with practical, real-world ethical dilemmas.
