What I don't get is why people insist on guilt tripping average people over their one nice leasure time of the year, when it realistically makes up only around 2% of emissions and is unnescessarily pissing off the average person making them dislike environmentalism, when you could be focusing all that negative energy on making a positive change by promoting green techologies that benefit everyone and address the most carbon intensive sectors of the economy.
Don't want people to travel by air? Why don't you promote, create or improve local travel destinations instead of making yourself the enemy of the people?
Just like the billionaire trained and funded Just Stop Oil morons & co, the only thing negative attitudes like that achieve is making normal people viscously opposed to environmentalism and apparently voting in far right governments.
I don't even get those kinds of vacations, it's stupid for other reasons, but I'm not gonna sit around complaining trying to make everyone around me miserable.
What is going to help is making people excited about green positive change that significantly improves their lives or at least doesn't affect them negatively, like making cities walkable and giving them a sense of place, promoting/selling/improving methods to make themselves green energy self-sufficent, promoting carbon negative construction, etc..
There are a billion positive things you could do to improve people's serf-like existance, but no everyone's insisting on making everyone else as miserable as themself.
