Until the ski resort closed due to lack of snow from global warming, his business failed as increasing amounts of financial capital were required for ever falling returns on new energy exploration, globalization collapsed due to increased fuel and energy costs making shipping child-labor textiles and fatuous electronics 12,000 miles uneconomic.
If your model of the world suggests that fishing isn't a sustainable activity, I suspect you'll find that the rest of the economic system is going to fail not too long after that.
While the ski resort was closing, the businessman created a simple video game called Minecraft which he later sold for $2.5 billion. Now he has fuck you money and doesn't give a shit what happens to the economy.
Until the economy collapses and he realizes that money is just an abstract concept that works as long as the economy exists. He dies from hunger trying to fertilize his field with banknotes and get bees to offer him honey in exchange for an electronic cash transfer.
1,000 years in the future, an advanced alien civilization digs up the remains of humanity, decodes all of our DNA, figures out all of our interactions, and decides to recompose the businessman and bring him back to life after discovering he was the creator of Minecraft.
Yes, there are a great many present fishing practices which are unsustainable, virtually all of them industrial. It's one of the great ecological tragedies of the 20th century / industrial age.
However primitive / simple line-fishing and small-net fishing have been practiced, sustainably, for thousands of years.
