My FIL is going through some medical issues and considered going mostly vegetarian to try and reverse the (irreversible) organ damage he was told he had. His plan was just fish, eggs and poultry, with red meat just once or twice a week.
I’m not often speechless.
You’re getting downvotes, but the implication that transatlantic tourism will grind to a halt is a big deal, and very real. For Iceland it’s an even bigger concern as so much of their economy depends on tourism (though this is the slow season).
One thing I haven’t heard mentioned is the Icelandic water spring source. It’s a big ($2B+) operation and (supposedly) located on that peninsula. I looked for it but could only find the operational/business headquarters.
