My dear , Srila Prabhupada explains in his purport to Srimad Bhagavatama, 1st Canto, Chapter 10, Text 4 the importance of protecting cows:'
"It is said here that the cows used to moisten the pasturing land with milk because their milk bags were fatty and the animals were joyful. Do they not require, therefore, proper protection for a joyful life by being fed with a sufficient quantity of grass in the field? Why should men kill cows for their selfish purposes? Why should man not be satisfied with grains, fruits and
milk, which, combined together, can produce hundreds and thousands of palatable dishes. Why are there slaughterhouses all over the world to kill innocent animals? Mahārāja Parīkṣit, grandson of Mahārāja Yudhiṣṭhira, while touring his vast kingdom, saw a black man attempting to kill a cow. The King at once arrested the butcher and chastised him sufficiently. Should not a king or executive head protect the lives of the poor animals who are unable to defend themselves? Is this humanity? Are not the
animals of a country citizens also? Then why are they allowed to be butchered in organized slaughterhouses? "
We must convince these cow eaters and cow killers to give up their heinous activity which causes all havoc to be manifested with the so-called human society. I say "so-called" because these rascals are not humans. They are less than animals. What animal kills that animal who nourishes it with milk?
