Yes, we should flyi less, however

..% of people that say to try to live sustainably admit to still fly frequently. 

80% of people never flew in their live. Demand for airtravel will rise.

Alternatives are not always available.

Most importantly, people fly for reasons that matter.

It sounds great. Planting trees, providing clean cooking stoves. But: suboptimal, ineffective and unfair.
