I may miss something but the linked studies say that neonicotinoids are bad (which I 100% believe), but don't actually say anything about the effectiveness of the bans.

E.g. it is possible EU agriculture replaced these pesticides with different ones which are just as bad, or with larger amounts of different ones.

I'm not saying we shouldn't have banned these substances, I'd just like to know if we have data showing this was actually useful.
