It's not stupid, they're literally exporting it.

It is stupid, because it just makes sense to have agriculture in a fertile area like the river delta in NL. And it doesn’t make sense to focus on protecting the very species that are not able to flourish without human intervention.

So, focus on protecting species that do well in nitrogen poor areas in the areas that are actually nitrogen poor.

If we move production around to average everything out we’ll end up with a more homogeneous Europe, less production and less biodiversity.

You're turning things around. These species are suffering because of human nitrogen pollution. Where does all the excess nitrogen come from that is preventing these species from flourishing? Oh hey, turns out it's mostly agriculture.

Most species we want to protect now only thrived once because people extracted nitrogen from the area, like in the case of heath fields and woodlands. Or became sand plains because we repeatedly burned down the forests for military reasons.

I don’t know if you know your history, but farmers do.

why? export within countries of the european union is comparable to export within states of the USA. i don't see the problem here.
