Agreed, I'm not saying government is not responsible for it, they provide grants for renewable energy, create power plants, give tax cuts for people with own solar panels etc. But it's up to people how that energy and material is used, is it wasted or used efficiently. So far, we're great at wasting everything.
Absolutely, our current way of life in the western world may not be completely sustainable. We're competing for a share of a shrinking pie with growing and advancing economies across the world, economies that we are also heavily and inextricably dependent on. I think to some extent we need to accept this and figure out ways to manage the painful transition to a long-term sustainable civilization.
