Who is at fault for an infestation of rats in NY? Rats or the environment (trash system)? And what is the best way to solve it - try to change rats (read: change people's individual culture, which might be fine by itself somehere else, but is problematic in NY) or to change the environment (trash collection)?
Rats do what they do, nobody is blaming them per se. They are just not welcome in places they are a nuisance.
