And the harsh fact: for you to live, something else must die.
We only focus on factory farm operations and the possible illegality of filming illegal actions. Yes, there are horrible practices in many parts of industry (I would say more horrible than not).
I just got done watching a documentary about plant communication on Nature (PBS). They also seem to be able to identify self, relative, and non-self. They communicate across species about predator information. They initiate active chemical defenses against organisms that attack them. They also respond to negative stimuli (pain). All things considered, they seem to be able to think and feel similarly to the animals.
Now.. I say this why? Most people would have no compunction about killing a plant for food, yet many I know would strongly object in killing a cow or chicken to eat meat.
My point is this: plants and animals seem to feel pain and seek to minimize it. Plants and animals are both living. I would not say that any specific plant is any more or less important than an animal (including us). However, for us to live, something must, inevitably die.
I make a thanks to the beings, plant and animal, I consume before each meal.
