I'm still feeling this argument out a bit, but... what can an individual actually do about it? Even if you look beyond how little any individual family contributes to pollution, in comparison to even some of the simplest industrial ventures.
I can't do without electricity 24x7, because I live in the north. I'd freeze to death. Think the recent crap Texas had to go through, for around 8 months of the year.
I can't do without a car because my commute is around 20 miles one way. I - quite literally - can't afford to live closer to work; the prices are on par with the bay area ($600,000 1,000 sqft condos), despite living in a very sparsely populated state with "competitive" wages in the $80k range for experienced software developers.
I could (and have) done without airplanes, but the alternative (if I want to keep my job) is to drive for around 18 hours. Not terribly friendly. The bus is closer to 48 hours, with prices on par with the airlines.
It is, for all intents and purposes, impossible for me (for a vast majority of people, I'd posit) to live without a job, without electricity, and without a car. And, realistically, I have very little control over my house, my car, my food, etc; these are instead largely based on my salary.
I get what's been made available by the market to me at a price that I can afford. It's not as if the market will change to less profitable products just because they're a bit better for the world. And it's not as if I can suddenly afford more expensive products just because they're better for the world.
