samudra you moron, You moron, if whole world bcomes vegetarian, then there will not be any food available to eat for these vegetarians as Earth cannot produce so much of vegetation so that it can fill 8 billion people in the world. Common grow up you moron. Be thankful to non-vegetarians becoz of home you are able to eat veggie stuff. Think logically, the people who are living in desert, how can they eat vegetarian food.
Who told you that eating non-veg food will make people violent. For your info, most of the hindus eat non-veg in India except for brahmins, jains, lingayat, etc. In fact in south India even Brahmins eat non-veg. So don't be in assumption that all hindus are veggies.
