Depends on where you place worth. Some people say life is precious thing, but how precious something is determined by its rarity and with 6 billion people and more joining each and every day that rarity is not readily seen so human life is loses its glitter, but if you take the scope of the universe we may be just one tiny spec of a world in an otherwise dead reality thusly in truth life is really rare.
Okay, I am rambling nonsense. BLAH!
