vegetarian There are still many who abstain from animal products like milk and its preparations who are knowns as "Vegan vegetarians' Some go still further and live only on fruits, who are called 'fruitarians' In India there are lactovegetarians who generally do not take eggs
Initially the human beings may have been non-vegetarians because of living in primitive conditions and absence of agriculture But as the vegetation increased and agriculture was practised the food habit went on changing from non-vegetarian to vegetarian What is the need of taking non-vegetarian food by killing the living beings while there is abundant variety of vegetable products and food
