Raised organically and murdered brutally.
Murder is a human intentionally killing another human. Animals that are killed for meat (at least in white owned humane places) are stunned first and/or bolted in the brain so that they don't feel pain.
If it is humane to reduce the amount of pain, how is it ethical to kill?
We are predators. Our eyes are in the front of our heads, we have canine teeth, our brains work off of fats and we are most healthy when we eat meat. There are many predators that all exist to keep the number of herbivores in check. The way non human predators kill their prey involves a lot of pain and suffering, and sometimes they prey is eaten alive. We are part of the balance. If predators did not kill prey, the prey would increase unchecked. Becauee the weak are not being picked off, they would breed and generate a weaker species. They would increase in numbers to where they eat all of their food and would die off. They would completely ruin their own ecosystems. Look at what happens to a pond in a city when Canadian geese are there. There are no predators so every mating couple breeds a dozen geese, then their shit causes algae blooms in the water, choking out the sun and killing everything under the water. We are not herbivores, it is our duty to keep the balance for all species on this planet.
