Chandu, as far as my views goes I consider vegetarianism is principally of consuming foods that come from plants such as roots, leaves, stocks, fruits, grains, etc. Basically, any part of a plant that can be safely consumed by a human being. I don't really consider dairy products as being vegetarian in nature because that comes from cows, goats, etc and I don't consider eggs vegetarian either because those come from ducks, chickens, and geese.
As to the issue of avoiding the destruction of any life form then you are going to find that is pretty much unavoidable no matter what you eat regardless if it comes from a plant or an animal. Fruits carry the seeds required for that plant to reproduce so if you happily munch down on an orange, apple, grape, etc you are in a sense killing the plant's young. You can minimize this by saving and planting the seeds, but most people don't do that. If you cut down a celery plant to eat its stocks you are once again killing that plant to eat its stocks. If you dig up a carrot or onion to eat it you are once again killing the plant because carrots and onions are a vital part of that plants root system. Eating its roots is going to kill the plant. Grains like wheat, oats, etc are a part of a plants reproductive system so once again we are back to eating the plant's young.
Point being, if you are adopting vegetarianism out of some altruistic sense not to kill life be it fish, cows, sheep, fowl, etc then you haven't considered the fact that we kill plants all the time in order to eat their seeds, roots, stocks, and so forth. Unless a person is willing to starve to death taking life in order to survive is all a part of the natural order of things. Every animal in the world does it so I think adopting a vegetarian diet should be done out of health benefits not because someone is squeamish about killing a cow for hamburger or turning a chicken in to chicken filets.
