The Dutch government has botched implementing these environmental reforms quite a bit in the past, which has caused right wing / anti enviromental parties to swoop in and claim the bigger environmental rules are the problem, instead of the way they were implemented.
There’s this one big ‘farmer’s party’ and a lot of farmers have bought into their lie of representing actual farmers, but the party was founded by lobbyists and their biggest donators are chemical companies who would benefit a ton from being allowed to pollute
You’re correct on your analysis, older governments and the farming industry alike essentially ignored the problem hoping it would go away (spoiler: it didnt).
Luckily that farmer party is not big anymore. They do still hold quite some seats in the Dutch senate from the 1-2 elections they were big (which they will lose in a couple of years), but not in the house anymore, where they are essentially only a small party now and hold / are projected no more than 2-4 seats of 150 seats in total. (Sadly most of their voters jumped ship to the next group of populists, the anti immigration party 🥲)
