>Not saying people have to go vegetarian, but reducing meat consumption or using more efficiently produced meats (in terms of land use) would overall make the world a nicer and more interesting place.

I've seen articles and threads like this for decades at this point. And the only thing any of you have convinced me of is that I must start securing my own production of meat. This is, I think, the exact opposite of "more efficiently" at least from your point of view. I will be unlikely to reach the feed-to-gain ratios that professionals regularly achieve.

Swine and poultry already in progress, beef and more exotic stuff within the next 2 years.

shrug poultry is already several times more efficient than beef in regular production (to say nothing of if your coop just has chickens wandering around finding their own food), and healthier for you. And hopefully your swine and poultry are having overall decent lives. And, if your beef is entirely grass fed (I doubt you can afford a finishing lot) you're still overall not using cropland to fatten up cows (but maybe that's your goal, who knows)

Anyway, you do you. Just offering my opinion on this 'cause it seemed like a good place to do it.
