There are problem causes that are very hard to address. E.g. alcohol consumption causing a lot of traffic accidents.
Or massive corporations, with huge lobbying budgets, releasing toxins in the environment. Toxins that cause no obvious harm, but kill a lot of bees or cause cancer in some humans after 20 years of exposure.
Do they actually die as a result, or just continue living somewhere else? Because if the problem is just that beekeepers lose them, that doesn't seem so bad as if it actually decimated them.
