Chocolate

It would be great to say that it's little things that really make people stand up and take notice. It's not obviously true, though, if previous Crisis period are any guide. There was nothing little about Pearl Harbor. Secession wasn't a minor issue. Maybe the original Boston Tea Party, where the tax on tea becomes symbolic of larger problems. A huge fleet heading for your homeland is the opposite of small.

Still, the possibility that chocolate might become unavailable seems like something that could get people to pay attention to what's going on around them, and possibly to demand changes.
