Raising my own poultry, which is the meat I mainly eat, has reduced how much I eat.
Having to wait until a hen goes broody, 3 to 4 weeks to hatch a chick or poult, then 16 weeks to 6 months before I start harvesting. Lot of time, effort, feed and especially stress getting them there. Also taking a life is not something I take lightly.
I also eat eggs of course, and can wild salmon. Sometimes I trade turkey eggs with a farmer for pork or beef. I have a big garden and some years I grow enough veggies for most of the year....other years I would die of malnutrition if I couldn't get to the store lol
