I fully understand. I did that for a long time, too (working and participating in a frequent flying environment). But that's really where we need to change society. The way we think about things that we have never questioned before.

And one additional thing should become very clear: it's not only about our footprint. Someone needs to stop others from destroying everything, from flying, from coal rolling monster suvs etc. And as there are too few people being that someone, we need to be that someone.
