Except for the fact that most of aviation's pollution comes from passenger flights and it pollutes a whole lot more to travel by plane vs car.

Put four passengers in a full sized truck and make them travel cross country vs put them in a plane and make them travel halfway across the country, their environmental impact is lower in the truck even if they traveled twice the distance.

There's nothing normal about being able to visit the whole world in our lifetime and it's a concept that didn't exist 100 years ago. We would do perfectly fine without it... Heck, we would do better without it because that would reduce our global emissions by at least a percent and potentially 2% depending on what people decide to do during their vacations instead.

Not even talking about emissions, the temporary clouds that planes create contribute to more global warming than all the CO2 emissions by the industry since its creation.
