Worse still - the problem is worse then you think and the solutions are more complicated then you suppose. If you stopped all air travel it might make emissions go up. It might reduce economic growth that makes implementing other fixes harder not easier.

There's a reason all of these emissions are produced - it's pleasant to imagine that it's all about things that don't really matter - does some rich guy get a sports car or an econobox - but I genuinely don't believe it's that simple. Instead it's a series of complicated decisions about productivity, value and risk.
