Not trying to be overly flippant... who cares? The paper opens with "to feed a growing population" without asking is that what we need? want? where we are actually heading to? Is feeding the world a real problem? I've yet to see compelling evidence that it really is except as a secondary effect of logistics, energy supply, and war. edit: I understand the environmental impacts.

Agreed. The market should decide if beef consumption is viable. Ultimately energy is the basis all food production. Cheap and plentiful energy solves the food production and distribution problem, then its just matter of preferences.

Earlier quoted context omitted.

Most cows don't eat grass like a wandering herd. Most cows eat stuff we grow on farms that could grow stuff we can eat instead. https://www.ers.usda.gov/amber-waves/2024/december/ers-data-... and https://www.ers.usda.gov/topics/crops/corn-and-other-feed-gr... Let me surface a more direct article: https://insideanimalag.org/land-use-for-animal-ag/#:~:text=1... Of the total land area of the contiguous 48 states, ~45% i…

The first link you posted says that 29% of the land is used for pasture and 15% is used for crops (which will include both human and animal). So yes, most cows are eating grass like a wandering herd.

Market also decided that the Irish could only eat potatoes.

it seems disingenuous to problematize beef. it turns grass into human energy and also requires civilizational practices that create and preserve human dignity and animal welfare. mainly, the so called problem serves to centralize the problematizer themselves. their arguments from a position of centrally planning and managing food economies are intellectual tarpits. however, that our food supply and rural ways of life have the attention of the perpetually concerned is worthy of note. when they start with their opinions, mind your wallets and assets. in short, avoid.

> If excess beef consumption were reduced to healthy quantities, as defined by the EAT-Lancet healthy reference diet, and substituted with chicken in forty-eight higher-income countries, the lost calories avoided would be enough to meet the caloric needs of 850 million people. It's really impressive how efficient chickens are compared to beef. Obviously thinks like legumes are way more efficient, but we've really bre…

It absolutely is and in some ways we've only just started! Although we definitely shouldn't move fast and break things with living animals and our food supply;)

It’s hard for the market to decide on its own when the environmental damage of meat production is left as an unpriced externality and when government subsidies are handed out like candy.
