I understand what you're talking about and from time to time I find myself at the same point. But then the every day life pulls me back to normal (?) and I think, there's nothing I can really change. And few hundred years later we crash into the sun and everything will be fine. Until then, I'll buy my organic food, avoid plastic bags and try to give my family as much love as I can.
I can feel your painting and it makes me sad.
