Sure I use lithium ion batteries too, in the developed country I live in, I can't go and live in a cave. But I won't buy a SUV that weighs 2 tons to sit alone in it most of the time and have it parked 95% of the time in a garage.

The "what have you done" attack is a bit too easy and, really, this is not about me.

We should strive to be sober, to buy repairable goods whenever possible, to educate ourselves on environmental impact of things, and perhaps more importantly to teach this to our children.
