I need to be careful about making statements about meat production being wasteful, however. As a third generation city-dweller, I read statements like that on vegetarian websites and don't have the background to critically filter their arguments. Thank you Finny and SampleMan for enlightening me, and others.
Gracious, elegant reply! Therefore I STAND CORRECTED regarding my post 39 in that there are some (very very few) exceptions, and I’m very glad that you’re a “lucky one” for whom this approach works (I once had a roommate who had a rare genetic condition where even once piece of bacon would raise her cholesterol level to a dangerous state). But it will be interesting to see if, ten years from now, your vegan-and-artificial-supplement approach hasn’t had some rather serious side-effects, like increased allergies and mental instability (lack of B12 takes years to manifest). One thing I expect is that you’re smart and open-minded enough to introduce meat and animal protein into your diet if and when you need to. Blessings to you.
