Nature has its own rules, from which we emerged*. As in any great metabolosm, cycles of construction and destruction interact to build and release. We can help our natural environment - for which we depend on greatly for services like water cleaning, deionizing, provision of oxygen (what happens if the world is desertified - at what point are we in trouble for oxygen??)
*If you want to say that God/Yahweh/Allah/Great Spirit created nature, i'm perfectly fine with that.
