Corn in the US is mostly used for harmful purposes. It's used for producing fodder for intensive cattle farming (which of course produces lots of CO2). It's used for biofuel production, which as the article observes releases more CO2 than that it saves. And it's used for producing corn syrup which is an ingredient that nobody needs in their diet. The rest, which would be usage for e.g. corn bread or other staples of…

> Nothing wrong with e.g. organically farmed corn. There is nothing wrong with “factory”, “industrially”, or “sustainably” farmed corn either. Farming at scale is the only thing that allows all 8 billion people to eat.

The romantic view people have of peasant farms is ruining all discourse about agriculture. I blame the books people read to toddlers.

Peasant farms were labor intensive, disease ridden, high risk, low reward businesses that shortened lives and ruined families. But somehow for a lot of people this episode in the history of farming is seen as the optimal blueprint for sustainable farming. They ignore the fact that all "successful" examples of small scale circular farming are making their revenue from donations, venues and from "selling" the model. Not from produce.

Maybe repurpose the subsidies to have those farmers do something that actually is more productive and less harmful. So once we've put all the farmers out of work and declared success, what do you suggest they do that is "more productive"? Should they lease their corn fields to crypto bros?

Why can’t farmers just get real jobs? Work in a coal mine or something instead.

I am unimpressed by the idea that we can solve this with more technology. Some of those billions of people feed themselves. Theit biggest problem isn't minmaxing an 8t/ha yield to 11t/h. Their problem is getting from 1t/h to 6t/h which is entirely possible with just manure, some crop rotation and good quality seeds that can actually be resown.

The idea that e.g. hybrid rice is going to solve world hunger is absurd.

Wouldn't the CO2 from corn be drawn from the atmosphere in the first place? Sure, if you grow corn and let it die, parts of its CO2 content would be bound in the soil. But does that calculation make sense when we look at our fossil fuel consumption? Sure, every bit helps...

Making ethanol involves more steps than just letting corn grow on its own, and those steps burn fossil fuels.

Well a lot of conventional farms that are hyperoptimized barely make enough money to get by. It is quite weird how we can't maintain something as basic as food security with a market based economy.

Putting PV on the fields produces a lot more energy per hectare than you get from energy crops and you don't need fertilizer, pesticides or heavy machinery.

Unemployed farmers should just join an afforestation project and produce more farmland.

Farming at this scale allows people to eat meat for every meal.

Or... and I'm just spitballing here... perhaps switch to more productive crops? I would hope that no one believes we need fewer farmers here in the U.S. (we need more, IMO), but don't incentivize them to produce more of a given type of crop than actually makes sense.

Switching to more productive crops wouldn't end subsidies. In face, we'd - at first - need more just to make sure folks have the proper equipment. If you currently grow corn and soybeans* then your equipment will be specialized for them, generally. I don't know about the current landscape, as it has been years since I've lived in the states, let alone mingled with farmers in the US, but at one point, they would pay f…

I don't think anyone arguing that subsidies in general are bad, just that subsidising corn is bad...

Whoa there chief. The whole 'that would be a good thing' is an overreach. There are 'better' ways to spend that subsidy but having a steady surplus of food subsidy or not is a way better position for a country to be in than implementing some JIT mechanism with supply/demand set purely by market prices. Just because agriculture makes up a small % of GDP compared to tech we can more easily get rid of Google than we can get rid of grain.
