Those country comparisons are totally idiotic because they produce the wrong fears. Example: look at that table https://en.wikipedia.org/wiki/List_of_countries_by_carbon_di... , Switzerland is 4.8 tons and a third of the US. I like the US but Switzerland is another scale for quality of life on most metrics.
Air travel is one of the few things that’s hard to fix, but for example I can’t understand why everyone won’t buy an EV, that’s basically 99% the same as an ICE car and even better in many aspects. Probably less meat, that will make food cheaper and people will live longer. Else all pretty much the same. Hell, nothing can beat renewables at the moment. They are 4-5x cheaper than fossil fuels. So we’ll be richer with renewables, well save trillions in insurance and I have no clue how people can still thing fossil fuels are the way. Inform yourselves and start to think about the near future, not the past. Stop being a passive fossil fuel lobby repeater.
