As some one mentioned above, eating meat is necessary for the food cycle to be complete. Or you will have to be content with cows, goats & chickens roaming your street and laying eggs in your porch. But, then you would complain that the Government doesnt do anything to control these animals. Have you heard of culling? why seals or deers are culled (read killed) Because they cause environmental havoc with their large numbers. If we dont eat the chicken and goats, we will have a similar problem in India.
And all so called proofs of vegeterianism being better is based on the assumption that you have a steady supply of plant based "alternatives" to meat which can never be possible for India's 1 billion children.
Again, no scientific study has proven that vegeterian diet is superior to a non veg diet. They all state one thing , that you can get the nutrients of meat by choosing the correct(hard to get) veggie diet.
