the animals thank you
LOL, no they don't.
Without predation the balance gets screwed up.
Populations get so far out of whack it starts having a negative effect on the species (humans?).
Just imagine for a sec that humans stopped eating animals.
Cows will still be making more cows and eating.
Pigs will still be making more pigs and eating.
Chickens will still be making more chickens, even more if we are not harvesting their eggs...and eating.
So now you have cows, pigs and chickens disease ridden and starving.
Human consumption keeps their numbers in check.
Now this is total BS. These animals are mostly BRED to have enough for human consumption. If we all stopped eating them we'd simply not breed any more and things go back to how they should naturally be.
Lots of farmers would get in trouble and would have to find something else, but that's another discussion.
As for not eating meat cos you feel sorry... in a way I can follow, but these animals come in for that purpose. Without it they don't have the chance to live.
Like many human souls come in with the purpose to die in a war or disaster etc. animals also come in with a purpose.
Many people still need meat in order to remain healthy as we need certain things that are not in plants.
But as we get further as a species -and we are- more and more won't need meat anymore and will stop doing so at some point.
If you can afford it you can buy bio-bred meat and take the time to thank the animal who gave its life for your meal is always good (that's what praying is actually about).
The rest will sort itself out in due time.
