Why do you think it's a good idea to buy olive oil from Tunisia instead of from California? Are you aware of how much CO2 is released to ship a trivial commodity across the atlantic ocean?
Just a guess as he said his favorite olive oil so could it be one tastes better? I imagine like many other things taste can be effected by the region it is grown in.
As for your other point in a perfect world we would all care about global climate change but many are not going to eat something they don’t like to do their part. But really cargo ships are small fish in such a big problem. Ban private jets or cruise ships would be way more beneficial.
Help me understand your viewpoint here - is the assumption that an entire ship is dedicated to shipping trivial commodities and the cargo isn't co-mingled with anything else? At the same time, what isn't counted as a "trivial commodity", and should ships _only_ be used for those items?
It just seems like the only things we should be importing from across the globe are things that absolutely cannot be produced domestically. For example, I've heard that coffee beans only grow in certain climates, so that would be a commodity that makes sense to import.
Pretty much everything else, including this supposed Tunisian olive oil, just sound like luxury goods to me, and should be priced accordingly.
GHG emissions from boat transport are actually a very low % of the total GHG emissions from producing that food. Moving it across the country on a truck would certainly produce more emissions than shipping it by boat from abroad.
