>Well, that's definitely a scary framing. Does anyone have sources for this specific prediction?

I read somewhere that the energy required to produce a unit of basic food products (say, wheat) has been multiplied multiple times over the last centuries because of overuse and pollution - despite the high efficiency of current machines and chemical fertilizers. I can't find the source but would be glad to find it or a refutal.

I don't believe that study was regarding climate change but rather the unsustainable nature of modern agriculture. I am a hobby farmer and have done some study into the nature of fertilizer, problem is that our fertilizers destroy the soil and so each year it requires more ferts than the prior year. I believe that the study was referring to this trend.

I agree. The more I read about climate change, the more I realize it's only one part of the anthropocene - so I often end up mixing the two. Anyway, if you do have a source for the diminishing returns of energy use to produce food, please share!
