Abstract

On April 19, 2024, the New York Declaration on Animal Consciousness was announced at the “Emerging Science of Animal Consciousness” conference held at New York University. The New York Declaration is an effort to showcase a scientific consensus on the presence of conscious experiences across all vertebrates (including reptiles, amphibians, and fish) and many invertebrates (at least including cephalopods, decapod crustaceans, and insects). Scientifically, the New York Declaration marks a significant advancement for humanity. However, it also brings heightened awareness to the moral challenges associated with animals that have conscious experiences (or phenomenal consciousness). This article will discuss philosophical approaches to the moral issue of killing sentient beings, thereby highlighting an existing moral dilemma in human society: In sustaining human survival, a species considered to have morality, we have to violate our own moral standards by killing other species with intrinsic value, consciousness, or sentience. This moral dilemma has long been present in human society. Various solutions have been proposed and implemented in practice to address this issue, such as the non-violence and vegetarian approach of Buddhism, the application of Islamic law and sacred rituals to animals in Islam, animal rights movements and voluntary extinction in Western countries, and the technology producing meat using animal cells. However, despite these approaches, we have not yet been able to fully resolve the dilemma, as sentient beings continue to be killed for our survival. We believe the most feasible solution is to change the current food consumption culture, build an eco-surplus culture to mitigate climate change, prevent deforestation, and promote peace.
