"If this were an invasive species (like murder hornets or malarial mosquitos) problem that could be stopped before it started or a temporary measure to prevent life and death (rather than wealth accumulation) for a significant number of people" I wonder what recent event governments could have used to show that this was a reasonable course of action to take. One that they could manage easily when it is in its early stages, having been warned about it. Perhaps one that affects humnans? What thing could they have managed better that would make us trust our government in the UK to be using this known bee killer to manage a disease for a greater good later on?
