Hare Krishna. I have been an ISKCON devotee since i was 1 year old and have been vegetarian. Seeing me, my non- vegetarian friend would also like to be vegetarian. But her only condition is that i have to explain her why should she defy the food chain ( as in snake eating rats, eagle eating snake etc) to be a vegetarian?. She says everything in this world has to be balanced. And food chain helps it to be balanced and if we stop consuming animals, we will not maintain the balance. How do i make her understand?
