As insect farming scales up for food, feed, and research, the question of insect sentience and welfare is moving from philosophical curiosity to practical policy question.
Insect welfare is one of the most challenging frontiers in animal ethics. The uncertainty about whether insects are sentient, and to what degree, creates a genuine moral dilemma: insect protein is presented as a sustainable alternative to conventional animal agriculture, but if insects suffer, scaling insect farming could represent the largest expansion of animal suffering in history. The precautionary principle — taking protective measures in proportion to the probability and severity of potential harm — argues for developing welfare standards for insect farming now, before the industry reaches the scale at which reform becomes politically and economically difficult.
