The whole sugar/candy industry is unethical in my mind. It may take some decades for society to catch up, but eventually eating sugar the way we do today will be seen like smoking and the tobacco industry.
Why not extend this to basically everything not essential to life? Traveling to tropical destinations is clearly harmful for the world, living in big homes spaced out from each other is another one that causes unnecessary pollution. Selling alcohol, foods high in saturated fat (butter), etc.
