Why should be Vegetarian
Being vegetarian is not only good for India but for the whole world. Requirements for growing a vegetable or a grain are much less than that for any meat produces.
A crop takes much less water in a season than an animal consumes in its whole life time. Almost a 1000 times less to produce same weight of food.
Land needed for a crop to grow is much less than that is required for raising animals . In later case land includes not only the farms where animals are kept but also land where special crops are grown to feed them.
Storage of meat requires much complicated and expensive system than that is required for a crop. Meat requires refrigeration, preservation and quick transport system which results into consumption of large amounts of fossil fuels.
Besides above vegetarian eating is consider much healthier and can save money on your medical bills.
