I wonder why nobody complains about fish. There they are, looking at you and your children with their sad, dead, milky eyes, if they still have a head, that is. Next somebody wants the fishmonger to blacken the windows of the sales counter (or however that thing is called).
Yep. It isn't possible for everyone living in a big city to hunt, but in theory, that would put the whole 'where do I get my next piece of meat' into the right perspective again.
In the past people didn't waste meat, it was too expensive and rare. They didn't eat meat every day or several times daily. They also wouldn't dream of wasting all the tasty things Andy and zombie mentioned. With my background I wouldn't eat liver, kidneys etc., even if I would still eat meat. I had the pleasure to work with those in the lab, frankly they are the garbage can of the body and today's garbage isn't anything I'd wanted to eat. And don't get me started on the number of antibiotics that didn't work on my astrocytes cultures, because the calves where the brain came from had been treated with them since day one of their existence.
Oh and rustle...does a cherry tree count if I planted it myself?
