As much as I feel like a jerk to be saying this, but theres no denying to the fact that somebodys gotta die for the other to live. Its a constant process, its just a matter of who has the upper hand. In the jungle carnivores have the upperhand, in the civilized world, humans have the upper hand. Just like Darwin said "struggle for existence"!! At the same time, think of what will happen to the balance of ecosystem if we didn't consume other animals. Think of what will happen if lions and tigers started chewing grass..... think of the over population of our "food" animals if they are not eaten up. I love meat, I eat meat bihaana, diuso, saanjha, beluki... all the time, why not??? We eat whatever is in easy supply and edible. You might say its causing pain to the animals but would you like it the other way around then?
