>eat well raised cow meat

It takes significantly more feed to raise a cow. The calories extracted from cow meat is extremely inefficient considering the high number of calories in (feed) and water. So, you could not use feed (vegetable death-per-calorie!) because it's something like a 8:1 calorie ratio for feed to a pound of beef. You'd have to pasture raise the cows.

There is no feasible way to ensure that all food is pasture-grazing cow meat at a price point accessible to most Americans.

There is currently no cruelty free-way to have cheap, accessible calories. If you really wanted the lowest death-per-calorie, one of the most feasible approaches would be consuming large amounts of rice.

I don't think anyone would want to subsist exclusively on a diet of rice, beans, and dietary supplements.

Maybe Americans (westerners in general actually) should simply eat less? 3 oz of meat per day is enough (5 oz of protein is recommended, but part of that can easily be filled by grains, legumes, cheese, milk, etc...). No one needs 10 oz of meat per day (current average consumption for Americans).

Not only that, the long lost art of growing it yourself. Both animals and produce. Then you have complete control over the process

I think this is a part of the problem in dominantly meat-eating cultures: they don't realize how diverse and nutritious plant life is. Treating meat and perhaps milk/eggs as real food and the rest as mostly fillers and in-betweens (I know I did).

Even without meat/milk/eggs/animal products, rice and beans, even barring all legumes and cereal grains, probably even barring all grains (e.g. amaranth, buckwheat, chia, quinoa, also sunflower, poppy, hemp..) there would still be enough plants life to have a diverse diet and probably even fully nutritiously sufficient diet without artificial supplements (a couple of micronutrients can be tricky, e.g. B₁₂).

Many, perhaps even most of the remaining diverse crops are currently notably more work to grow, but they should still have significantly less ecological impact than eating excessive amounts of meat.

If a cow is not raised in pasture, it's not a well raised cow.

Ruminant holon systems like those used by Polyface Farms (Joel Salatin of Omnivore Dilemma fame) are incredibly efficient at both producing calories and utilizing waste products.

Hmm? I am enjoying the wide variety of legumes, for one. :D I make stews out of them. :)

What do you propose? That we start eating crickets? Actually I would try some, maybe they taste like shrimp. Shrimp are another quickly reproducing species, but they're also sensitive to pollution.

I've had a dish of lemon grass stir-fried cricket. It was at a restaurant that served lots of bug based dishes. It was one of the few that we had that I'd regularly order.

They didn't taste like shrimp though. They also have a lot of chitin.
