Of course your epiphany might not have happened yet - to clarify what I mean, I'm talking about the moment when the realisation that our way of life is, I guess, an aberration, hits you. Suddenly you're aware that we're riding on the back of a depleting energy source, one that's use is impacting the environment to such an extent that the very narrow margins of environmental norms required to sustain it are being altered.
The moment you realised that we are unsustainable to the point we may well make the lives of our children's children untenable, that we may, in our quest for convenience, inadvertantly be practising vacarious genocide and taking along with us many other species on our path to our perceived perfect life.
This is generally followed by a decision on whether to do something about it, maybe we decide it's too late to bother, or that our actions don't count ... whatever, there's usually a point in which business as usual comes to an end and we feel morally obliged to do more than recycle our aluminium cans... has this happened to you? When, how, what provoked it, and what did you do about it?
