Locust control programs raise complex welfare questions given the enormous numbers of insects involved and the genuine humanitarian urgency of protecting food security from swarm damage.
The welfare implications of locust control involve genuine ethical complexity. Pesticide spraying kills billions of insects but protects food supplies for millions of people who would otherwise face starvation. The moral weight of these tradeoffs depends significantly on the contested question of insect sentience and the capacity for suffering. Developing more targeted control methods that reduce total insect kill while protecting crops, and investing in the science of locust sentience, represent proportionate responses to this welfare uncertainty under conditions of genuine humanitarian urgency.
