    As long as we don’t put more CO2 in the air, it’s not that big of a problem, but I think we’ve got more than enough nitrogen in our biosphere already. The excess nitrogen is causing pollution problems by itself.

      Yes. Part of the inputs to Haber bosch process is natural gas and a ton of process heat. The hydrogen source has to be switched to H2 from electrolyzers and the plant can’t burn the NG for heat. So the energy cost for switching is very steep. This transition is huge, as it would decouple production of food from fossil fuels.
