Similar with the artificial battle front between organic vs conventional/industrial, where each side claims the solution to sustainable food production, but no common ground is allowed.
By the way, not all children's books are equally naive. We've recently found a nice one [1] (in German) which shows small- and large-scale farms side-by-side, in a brutally honest way (including butchering).
If you're looking for similar books with realistic depictions of agriculture: No, that was a lucky find in the library.
In case you just want to practice German with media for children, I always recommend "Die Sendung mit der Maus" [1]. It's a mix of short animated stories with "how it's made" features, where they go filming in factories etc.
