Long ago i read ''somewhere'' that :

If you observe the teeth of herbivorous animals like the cow, goat and sheep, you will find something strikingly similar in all of them. All these animals have a flat set of teeth i.e. suited for herbivorous diet. If you observe the set of teeth of the carnivorous animals like the lion or tiger, they all have a pointed set of teeth i.e. suited for a carnivorous diet. If you analyze the set of teeth of humans, you find that they have flat teeth as well as pointed teeth. Thus they have teeth suited for both herbivorous as well as carnivorous food i.e. they are omnivorous. One may ask, if Almighty GOD wanted humans to have only vegetables, why did He provide us also with pointed teeth?

On other hand --> plants cannot feel pain, therefore killing a plant is a lesser crime when compared to killing an animal. Today science tells us that even plants can feel pain. But the cry of the plant cannot be heard by the human being. This is due to the inability of the human ear to hear sounds that are not in the audible range i.e. 20 Hertz to 20,000 Hertz. Anything below and above this range cannot be heard by a human being. A dog can hear up to 40,000 Hertz.

I don't like killing so looks like I WILL LIVE ON WATER :-(
