Time doesn’t have to be 1:1 between a host and a simulation. The host can take as long as it wants to render the next step in a simulation, and any observers within the simulated universes would not be able to discern the choppiness of their flow of time.
Ruminants like cows repair our depleating topsoil via regenerative farming (our current approach of using petroleum-based fertilisers is not sustainable)
A single cow’s life can feed a human for 1 to 2 years, compared to the many incidentally killed animals (insects, rodents, frogs, birds, etc.) during the growing and harvesting of crops, plus the destruction of entire ecosystems to create the mono-crop farms in the first place
Humans need to eat lots of fat to be physically and mentally healthy, and beef provides lots of fat (the low-fat high-carbohydrate diets recommended by various agencies — starting with the US’s department of agriculture in the late '70s via the food pyramid — are making us sick, with once-rare diseases such as cardiovascular disease, diabetes, depression, and dementia now commonplace)
