The Haber-Bosch process consumes around 1% of energy the world generates. "Industrial farming is tapping underground aquifers faster than they can be replenished, threatening global water supplies. Nitrates from fertilizers contaminate drinking water. Agricultural runoff rich in nitrogen and phosphorus has created hundreds of dead zones in coastal waters around the world. And then there's the toll taken on the Earth from the sheer number of human beings we can now feed." https://phys.org/news/2014-06-humans-derailed-nitrogen-track.html https://phys.org/news/2014-06-humans-derailed-nitrogen-track...
