If people wanna just eat veg, cool, its a lifestyle choice, go for it. Howvere, it is un-natural, so do not preach to me about it.
So you know what is natural?
A real "natural" life for you would be to die @ childbirth because of a pesky bacteria infection or bad hygiene later on or no medicine or a short, brutish nomad lifestyle or dying because of starvation well long before your 80th birthday. THAT would be NATURAL.
We are not living in a natural world anymore, we are living in an artificial, human-created environment, where everyone can grow old and die of "natural" causes instead of leading a hard nomad hunter-gatherer-lifestyle like the last 10,000 years before penicillin and all the other things like tap water, electricity and superior medical care were invented...
If you wanted to eat meat in a nomad's world, you had to go to great lengths or be quite rich.
Today, even the poorest jerk can just go to the supermarket, because we have a huge un-natural supply of cheaply mass-produced meat for you to swallow there.
If you think that eating something that has been pumped full of growth hormones is healthy, go ahead, yummy-yummy, fill your tummy.
After all, you are what you eat,
You are what you think,
And you are what you do.
