For the record: Yes, I sometime do discretionary travel by air. That's not ideal for the environment, I know that. On the other hand, I also have never owned a car, I walk or take public transit to work, and I have a solar system at home.
Imperfect people like me do what they feel they can.
@mattblaze There was a point where I couldn't afford a place to live in the Bay Area where my child was, but I could afford to fly around all the time and stay with different people, because that was more manageable than rent, and how I could remain part of my child's life. How badly does society have to fuck up for that to be the best option?
