The current methods of farming, both animal and plants, needs to change to a sustainable regenerative model. Any system that requires external inputs (especially petrochemical inputs) wont work long term. Plants and animals work together to regenerate topsoil and are essential to the biocycle.

I’m glad its working for you, but consider the larger implications of 7 billion people going all meat. Or even just the entirety of the US.

Great point, I'm glad you brought it up! Let's examine this.

Remember when people adopt a strict keto / carnivore lifestyle, they are not mindlessly snacking all the time, eating becomes intentional, people simply eat less (and no need for grains).

For the average adult male (lets assume all 7 billion people are males for simplicity) - they require about 500g of animal food per day (after adapting to a fat based metabolism) - don't forget most of the energy on a carnivore diet comes from fat, most of which we throw away now, so that is extra yield per animal)

Given that the current world fishing capture feeds 1 billion carnivores annually.

and Current world meat production could feed about 2 billion carnivores annually.

There is a gap in current production (3billion vs 7 billion), but the health of the people depends on closing this gap (more focus on range land, de-vilifying animal nutrition). Right now we are not prioritizing meat production and people's health is suffering, I hope we can rectify that.

Also worth noting that the majority of the worlds vegetarians are economic vegetarians (they don't have access to animal foods). But that speaks to a historical trend - the rich and elite eat meat, and the peasants eat plants (i.e. robin hood's Sherwood forest).... which is just another spin on economic vegetarians

Industrial agriculture in all its forms, including monocrop agriculture, is terrible for the environment.

"The environment" in and of itself is more complex than just emissions. Things like the water cycle and latent heat have to be considered too. Look at sustainable and regenerative farms. Ruminants regenerate the topsoil, irrigate ground naturally, and sequester carbon in the soil. This offsets their methane emissions. Also soil health and biodiversity in particular, I suspect, is something that we don't care about enough.

FWIW, I've been learning about how to become a regenerative farmer. There's a lot of learn about in terms of how one can contribute to the good of society by improving the environment around oneself. By looking for a plot for a farm, I've learned that there are laws here for land that can be used to farm crops, and land that cannot. A lot of that land can however support grazing animals.

On an aside, on the topic of "meat farming" vs plants, we should also consider essential amino acid yield and nutrient density when doing environmental impact assessments, and not just crude protein yield. Otherwise it's not really a fair comparison.

Agreed. Also, I should keep this in mind more:

But…Most conscientious people when discussing carnivore, always add… “we don’t know the long term effects of this diet”

I think I'm still somewhat in the "too enthusiastic about my diet" phase.
