Completely disagree. Airtravel has been consistently growing at 6% for a while now, there's still billions of people waiting in line to get easy access to it.

As your graphic alludes to short distance regional flights can be replaced with a greener alternative, but the vast majority of flights cannot.

Air travel is growing exponentially and we have no way to stop those emissions. Virtually everything else has alternatives, there simply isn't the energy/kg to move airplanes with anything other than petroluem products. Biofuels would be an even worse disaster.

High-speed rail is a great alternative to short flights. Sadly, the US has no high-speed rail due to the auto-industry.. https://www.youtube.com/watch?v=Qaf6baEu0_w
