You can't eat private insurance.
The consequences of not being able to produce enough calories is severe. It is much better to overproduce and everyone gets fed than producing just enough and a climate event erases out 20% of our calorie production.
The US produces an unbelievably enormous calorie surplus way beyond what is needed for the health of the country and in fact its detrimental.
The biggest is not even used as food, over half of corn acreage is used for ethanol. That's an amount of land that's truly beyond comprehension. Its a horrible program as well, corn ethanol is worse than the gasoline it replaces in terms of carbon footprint when taking land use into account. And it raises the price of food. And we even subsidize it multiple times, we subsidize the crop as corn and then we subsidize it as ethanol. Biodiesel and renewable diesel (different products) have spiked in recent years as well, most of that is made from soy, canola, or corn oil. They have similar problems though aren't as bad as corn ethanol.
Another huge negative surplus is the amount of liquid calories, mainly soda, that are consumed. Most nutrition science that I've read points to the enormous amount of liquid calories as the part of the US diet that is driving obesity epidemic. There are of course other aspects to the obesity as well.
Finally, substituting some of the US consumption of beef with chicken and some of the chicken with beans.
To recap US overproduces calories to the point that it hurts the country. It damages the land, the ocean with dead zones, the climate with carbon. We pay for it multiple times in subsidies and with higher food prices. It hurts our health which we pay for in suffering, shortened lives and health costs.
> over half of corn acreage is used for ethanol.
That doesn't mean much without more details. Corn is used as a tool in the crop rotation to enable growing foods for humans to eat. As we learned before ethanol's time in the sun, farmers are going to grow it anyway to support their rotations. The only question is if it is better to recapture that into usable energy or to let it rot out in the field.
> ... when taking land use into account
But if not taken into account? The harsh reality is that ethanol plants are unable to pay cost-of-production-level prices for corn. It now typically costs $5+ to produce a bushel of corn, while ethanol plants generally start to lose money as the price rises above $4.50 per bushel. You're not growing corn for ethanol. You accept selling corn to ethanol buyers when you can't find a better home for it.
Corn especially is a tough one to predict. A couple of years ago yields around here were nearly 100 bushels per acre higher than normal! Even if we put in the mightiest effort to grow exactly the right amount of corn for reasonable food uses, that 100 bushel surprise means a good 1/3 of your crop has no predetermined home right there. Of course, it can go the other way too. If you end up 100 bushels per acre short of what you expected...
Between needing to grow extra to protect against unexpected low yields, combined with unexpected high yields, half to the corn crop having no home (and therefore ending up as ethanol) isn't that far outside of what cannot be reasonably controlled for.

That's fair. We don't have the technology to do better, unfortunately. Maybe once LLMs free up software developers once and for all they can turn their focus towards solving this problem?
corn->ethanol is government subsidized robbery. I paid for those nutrients let them rot. Now consumers have to buy more and eat more calories to get the same nutrition. All so we can have net negative ROEI ethanol?
Your buffer here is meat. Cattle are tremendously inefficient consumers of grain. Eat your burgers in the bountiful years, then slaughter 75% of the herd in a hardship year, eat well for six months, then spend the next three, four, five years eating more grains while the herds recover.
Ethanol is another one.
That's the sensible way to do it.
Somehow I doubt that it's the way we do it... But maybe the variability is coming from world trade and developing nations.
Cattle are inefficient consumers of grain, but highly efficient consumers of grass. Most land used for pasture can't effectively be used for anything else.
This argument might sound good, but those cattle are fed crops, not just sunshine and the grass they walk on.
Most crops grown in the US are used as animal feed. They are dependent on arable land that could be used to grow food for humans directly and much more efficiently. We just like the taste, so we accept the inefficiency.

We feed the average cow >10lbs of grain and also some alfalfa for every pound of meat we get out right now.
Part of the cull would likely be shifting towards more grass fed production. Another part would simply be prioritizing chicken or pork for a while.
Americans would riot without burgers.
