I'm vegetarian and reluctantly accept that I'm a hypocrit as I still have (limited) dairy products. Milk is a by product of the meat industry.
I try my best, I don't any actual animals, only free range eggs and even though dd is not veggie I get her high welfare meat.
I don't wear leather, sheepskin or wool and wouldn't wear fur even if I could afford it.
I don't use make up toiletries or household products that are tested on animals.
Like a pp where I struggle is with medication, I request gelatine free wherever possible, take as few meds as possible but the few I take literally keep me alive. I regularly petition for animal testing of pharmaceuticals to be stopped.
But - if I or my child were at risk of starvation, especially my child, I would kill to eat. I'd try to do so as humanely and quickly as possible.
I do think many people now are absolutely clueless about where their food comes from especially as in the uk so much of what we eat is so processed it bears no resemblance to the original ingredients.
That fuels
poor animal welfare
the safety of food for human consumption - BSE, salmonella, the e-coli outbreak, horse meat being sold as beef (ethically I see little difference as a veggie BUT consumers had a right to know, plus what if someone allergic/intolerant to horse meat had eaten it)
food waste - because not only is it not appreciated but people no longer trust themselves to judge if food is "off" because the don't KNOW what it should look/smell/taste like.
Out of necessity I do a lot myself. Home maintenance, cut mine and dds hair, repair clothes, make simple garments, grow herbs, I used to grow veggies but no garden here, cook and bake from scratch. Some of which I've only learnt in the last 15 years since splitting with dds dad. But some I was taught by my parents who both grew up VERY poor. Sometimes I've thought I'm stuck due to some item breaking/wearing out and a chat with mum or dad and they say "have you tried doing X y z" and I haven't but hey I may as well cos otherwise the things only fit for the bin anyway... It's quite empowering.
To answer the op I think it would reduce meat consumption not because people aren't up to it but because most have become so detached from the reality.
