I am mainly a vegetarian, though I admittedly will cheat with fish -- I feel like I'm in a grey area where I don't know if I eat it frequently enough to constitute pescatarianism, though I would respect far more faithful vegetarians telling me I'm not truly veg. I went off meat for a combination of health reasons (lifelong digestive issues, and a plant diet has done wonders for it) and personal ethics.
I'm saturated with opinions about how western society should reshape its diet -- when people ask me for advice, I usually suggest that if you don't want to give up meat eating, then to buy your meat as locally as possible. Intimate yourself with the process and support the business model that is ecologically sustainable and far less torturous for the animal involved. Honestly, the same can go for a plant-based diet. We're killing the world transporting in unnecessary produce because the local cash crops are corn, corn, and corn for cheap corn syrup and cheap factory farm feed.
I know it sucks because not everyone benefits equally from local farming (if you're in a major city, your choices are threadbare without a strong, faithful community, and even 'farmer's markets' now are rife with deceptive business where trucked in grocery store produce is resold as local, organic food, many times its original price). It's also far more expensive to do this, so the sacrifice for omnivores is to eat less meat per week. Which, in my opinion, is what we should be doing. It's unsustainable and deleterious to your health to make meat a daily thing, whether it's carcinogens from the cooking process or nitrates/salts in curing, to elevated saturated fat levels -- of course, wholly dependent on your diet and family history.
I've heard great things about Impossible meat, but haven't had a chance to try it. I'm excited to! Manufactured meat is two thumbs-up from me, because really anything is better than factory farming situation going on. It's awful. It's awful. It is nothing short of pure suffering, both for the animals and for persons who work in those facilities -- usually migrant hires. They report higher domestic violence rates among those same workers, no doubt in part of the stressful and violent work they have to do. How could it not be mentally disturbing to assembly line dispatch of animals in the thousands, every day? There's frequent reports of factory animals being neglected or tortured, perhaps as the only outlet these workers have for their stress levels. It's not a hunter field-dressing his kill, and it's not a family farmer reaping his livestock. I equate it to torture -- the same torture people support when they buy products like foie gras. Giving up grocery store meat is the best forward step anyone could take.
My opinions are legion, hahaha!
