Prabhupada on the Protection of animals #Truth

He who gives permission, he who kills the animal, he who sells the slaughtered animal, he who cooks the animal, he who administers distribution of the foodstuff, and at last he who eats such cooked animal food are all murderers, and all of them are liable to be punished by the laws of nature. No one can create a living being despite all advancement of material science, and therefore no one has the right to kill a living being by one's independent whims. [S.B. 1.7.37] Prabhupada
