Pain and suffering is just part of life
Without pain you wouldn't feel the joy of relief, the joy of pleasure. You need something opposite to contrast that feeling/meaning. Happiness wouldn't exist without sadness. To me it's one in the same. They complete each other.
Doesn't mean I'm condoning the suffering of animals that we see in this documentary. But it's nature being nature. How can you expect all 7 billion human beings to be completely ethical to the treatment of animals? There is at least 5% highly irrational people on the planet and at the least 1% extremely irrational. Those numbers turn out to be 365 million that highly irrational, 73 million extremely irrational people. Which is the total of 438 million completely unstable people.
So the odds are there always going to be some form of abuse to animals and human beings. We're hard enough on our fellow man, how much more on other earthlings like animals? The pain and suffering is inevitable. You maybe able to curb it a bit. But to stop mass production of food, clothing, entertainment, wide spread experimentation on animals is impossible. Just like the war on drugs. A pointless one sided war.
And what is driving all this madness? Demand is driving this, the power of money. The same thing that drives anything that's in mass commodity.
