“………no one has the right to kill a living being by one’s independent whims.”
No, no one has the right to kill on whim. That is disturbing to most human beings. Hunting or raising meat to provide life sustenance is not ‘whim’, it is of necessity.
“God has given human society so many things to eat—nice fruits, vegetables, grain, and first-class milk. From milk one can prepare hundreds of nutritious foods, but no one knows the art. Instead, people maintain big slaughterhouses and eat meat. They are not even civilized. When man is uncivilized, he kills poor animals and eats them.
Civilized men know the art of preparing nutritious foods from milk.”
1. Many humans unable physically to consume or digest dairy products of any kind. There are many as well who cannot digest nuts or legumes.
2. Milk and eggs are acquired by exploiting the very animals you profess to save. Most of the animals that provide these are kept housed in small cages where they cannot move and this is total substance of their lives.
3. You mention nothing about fish or sea animals whose lives are also curtailed by many beasts including human beings.
4. You mention nothing about insects and other like-kind life forms who are the sustenance of many cultures.
Fruit, grains and vegetables are certainly necessary, but often not accessible to many because of the cost to acquire them in sufficient quantities. Many folks live in concrete cities or in developments who deny gardening, so these must be purchased in grocery stores.
Exploitation of animals goes far beyond just the consumption of meat however and far beyond that of beasts killed for food. Exploitation includes not just consumption but also manipulation, molestation, abuse of humans to humans as well within families and beyond. You mention none of these uncivilized conditions.
I am reminded of the parable of the Scorpion and the Frog http://allaboutfrogs.org/stories/scorpion.html and as this applies to human beings, we are what we are and it has nothing or little to do with being civilized or uncivilized…. We cannot separate ourselves as being any different from any other beast by the very nature of our design.
As I understand it, if we continue to evolve, one day we may be living energy of lights with no need to consume anything but random, floating energy. Of course, by then, someone may well tell us that to consume that energy is deviant and evil and it would be much more courteous to let ourselves just blink out of existence.
