Renewable energy tends to be de-centralizing. That is one of the reasons I like it.
Probably, and it is logical, human waste and excess is causing undesirable changes in the environment and should be corrected. This is for aesthetic, health and economic reasons. 'Nature' doesn't care, and, besides, we are nature, aren't we? Or did humans drop in from some other dimension?
Whether or not mankind is causing global warming is almost beside the point. The question is, what does it serve to excessively and uselessly consume energy and eject trash?
