Well, I've always thought of the Lifestream being somewhat akin to oil. Think about it. Oil is created by the compressure of fossils into a usible energy. It literaly contains old life in it. This is very similar to the Lifestream gaining new spirit energy when someone dies and their spirit energy is added to it.

Also, there's the blatant thing about sucking out Mako harming the Planet and being a limited resource, when the same kinds of quarrels are being had over oil drilling. I'm pretty sure that the game designers were trying to make that connection between Lifestream and oil. but it is just a theory.
