@lrockhq However, as one cannot disprove anything to 100% we use approximations when it "goes beyond all doubt" - and plants have never proven to possess intelligence, while the animals we eat most certainly feel and suffer from pain and stress which humans cause and would likely be better off if they were not bred for the sole purpose of being slaughtered.

An interest case is chicken farming (in Sweden at least) - surprisingly many (I don't remember the numbers, but a significant amount of the total number bred) are transported off to be killed (gas chambers), never being consumed in any way. Given all the medicinal issues with mass industrial breeding (disease, antibiotics etc.) they even need to be handled specially and can't just be dumped or burned as ordinary waste products.
