> Around me, its seems like slowly everyone is starting to doubt/deny the impact of nitrogen and whether it's something we need to care about.

I'm not sure why that's surprising. Our food supply depends on using nitrogen at the moment. You can't just ban it cold-turkey without transitioning to an alternative that doesn't threaten the food supply. Particularly with inflation issues, further destabilizing the food supply is insane at this time. The whole climate change agenda will be in jeopardy if this isn't handled well.
