A fishery on the decline --- lobsters are migrating away from the Gulf of Maine due to global warming/climate change (the Gulf of Maine is warming faster than all nearby waters). The loss of import sales to China due to Trumpian tariff "wars" has a significant economic impact on Maine lobster industry's ability to operate profitably.

Canada profits from these changes. Ocean water is colder there; rules allow for harvest of smaller lobster; China is instead buying Canadian lobsters, and even if U.S. tariffs are ever lifted, there is no reason to revert back to U.S. sources.
