I, for one, love to talk about zero emission food production. It's not scary, and in fact it will be somewhat straightforward to replace our nitrogen sources with zero emission production methods. Electricity can be used to produce ammonia in many ways. The most obvious is electrolysis of water to hydrogen, and then through the Haber process. Large scale production is already being planned, for example by Fertiberia in Spain, who will deploy many MW of electrolyzers soon. Spain's target for electrolyzers is 4GW by 2030! We couldn't even build 4GW of nuclear by 2030, but we will be able to do elecrolyzers and the solar to power them. There is also a startup (blanking on the name) that creates ammonia on site, off grid, using high voltage in a box. This eliminates the transport cost of nitrogen, which is not insignificant. By focusing on small scale production on site a small startup can break in to a huge commodity market. I didn't downvote your comment, but your unnecessary pessimism does not accurately reflect the future that we can see already!
