The tragic thing is that there's this idea you have to live life as an austere pioneer hippie to address this. You really don't. A world of mostly-vegetarian people living in modern, timber (for carbon sequestration) flats in mixed-use environments, using renewable electricity to power their heat pumps and AC, traveling primarily via bike, walking, and public transport, and owning less disposable crap would go a long…
Not even that far. Primarily vegetarian diets and less driving would make mountains of difference for the world. As someone who is fairly new to adulthood I dont really see why we work so much - there just doesn't seem like there is much to "get". There should ve a greater focus on tending our environments around us, spending money on experiences and creating art (or even just having a hobby).
Like I remember that one European Cruise company's ships produced the same amount of CO2-equivalent than all European Cars combined last year (or was it the year before that?).
All friggin EU cars? This is what I would call a lever.
And for what? For the sake of one company making money by providing a kind of recreation that could at least be discussed as it provides recreation - but recreation could be provided in a more environmental friendly way as well.
Just regulating this one industry would go a long way. And there are probably some other low hanging fruits still undiscussed.
Sadly the whole discussion seems to revolve around what the individual should/could do. Often it seems to me especially to mask the fact that regulating some industries would be a faster and imho more efficient way.
