I just flew from Brisbane to Melbourne, Australia. I love to fly and one of my great joys is travelling by air. The people watching at the airport, being up among the clouds, the adventure of going somewhere.

However, I’m increasingly wondering how much more I should do given the environmental impact.

If only Australia had reasonably priced high speed rail to traverse its vast distances. We have rail, but it’s neither high speed or value for money/time compared to plane travel.
