We have /c/fuckcars but no /c/fuckplanes. Yet a lot of the same arguments apply. They cause air pollution (roughly double the amount per km traveled), noise pollution and they (airports) take up a lot of space near dense living areas. Sure, some places can practically only be visited by plane, just like some places can practically only be visited by car. But people don’t consider not having your holiday that far away or giving pushback on a busines trip that should have been an online meeting. Besides work-from-home being encouraged, work-from-home-country should be too.
Cars need to be discouraged in favor of busses, trams and trains. Planes nees to be discouraged in favor of high-speed trains, staycations and hopefully new alternatives like modern sailboats or electric planes.
Imo people should strive to be better than average for where they live. Leads to continuous improvement. Never make the mistake of trying to be the end goal society needs to reach while everyone else is still far away, the mass of changes is important, so you’ll just make yourself miserable and not save the world anyway.
