Background In 1926, Fritz Jahr described bio-ethics (German: bio-ethik) as“the assumption of moral obligations not only towards humans, but towards all forms of life.” Jahr summarized his philosophy by declaring, “Respect every living being on principle as an end in itself and treat it, if possible, as such!.” Bioethics was thus originally an ethical system concerned with the “problems of interference with other living beings... and generally everything related to the balance of the ecosystem” according to the 1978 Encyclopedia of Bioethics. This defnition was predicated on the work of Fritz Jahr, Menico Torchio, and Van Rensselaer Potter. Methods In order to proceed with depthful analysis of the origin and major bioethical fare up, we will use criti cal analysis of existing literature, followed by a study trip to relevant bioethical localities (collecting photo and other documentations regarding Menico Torchio). Results While Jahr and Potter are typically given intellectual credit for developing the feld of bioethics, the eco ethical contributions of Menico Torchio have been forgotten.This article will frst trace the origins of“bioethics” – now commonly bifurcated into“biomedical ethics” and“environmental bioethics.” The former was developed by Tom Beauchamp from the Philosophy Department and James Childress of the Religious Studies department at George town University and is based on principlism, with a narrow focus on medical settings. The latter addresses the envi ronmental impact of the medical industry and climate change health hazards. Second, we will present a panorama of Torchio’s signifcant intellectual contribution to bioethics. Menico Torchio’s concept of bioethics synthesized work of both Jahr and Potter, advocating “the need to expand our ethical obligations and embrace the most developed groups of animals, not only physically but also psychologically.” Third, we will refect on the lasting legacy of“bioethics” on biomedical and environmental bioethics today. Thematic elements such as interconnectedness of planetary health and human health, dedication to living in harmony with nature, and emphasis on systems and symbiosis remain unchanged from the legacy of Tochio onward. Our conclusion will underscore the necessity of understanding the connections between planetary, environmental, and human health.
