I've been noticing this more and more, there's an insistence that pointed economic or environmental criticisms of some consumption habit, usually almost exclusively partaken by the upper middle class and wealthier people, must actually secretly be a purely cultural critique. I'm sure these guys work for Exxon or some shit, lmao.
the idea that you can decarbonize everything, including cruise ships, seem rather far fetched but i dunno

It's completely doable. The technology for it already exists, it just needs government support (and state planning) to be implemented, not to mention for the iron grip of the fossil fuel companies to be liquefied.
Cruise ships, shipping and aviation for example could all be retrofitted to use carbon-neutral synthetic hydrocarbon fuel or hydrogen fuel cell tech instead of oil or LNG.
Naturally, this would require an absolutely massive expansion of carbon free electricity, and really the only way that you can do it at scale is through nuclear and/or hydroelectricity power.
ngl kinda skeptical. the reason cruises are cheap in the first place is massive subsidies, tax evasion and regulation skippin on the high seas. just substituting for hydrogen doesn't make up for that, surely. plus, what hydrogen even since much of what we have is 'hydrogen, clean, sort of'.
i dunno i'm seeing a future where tourism is much more local
