1.1 Atlantic Cod

The issue with Atlantic cod is more about the environment and fish populations than human health. This species has been heavily fished for over a thousand years, and by the late 1990s, the fishery collapsed. While fishing for Atlantic cod has significantly decreased since then, the population has had difficulty recovering. Experts agree that the collapse of the fishery has caused lasting changes to the North Atlantic food web, and the species is now classified as vulnerable to extinction.

2. Atlantic Flatfish (halibut, flounder, and sole)

This is yet another example of overfishing and waste. Commercial fisheries produce what’s known as “wasted bycatch,” which occurs when fish or other marine species are unintentionally caught while targeting different species. Every year, U.S. fisheries discard approximately 2 billion pounds of bycatch, which is the equivalent of half a billion meals! The California gillnet fishery, which focuses on halibut, has been singled out as one of the worst offenders. If you’ve eaten halibut in the U.S., there’s a good chance it came from this fishery.

3. Caviar

Caviar comes from the eggs of the Beluga Sturgeon, a centuries-old fish that can live for up to one hundred years. These eggs are in high demand and can fetch thousands of dollars per pound. As a result, the Beluga Sturgeon is now at great risk of extinction. The same threat applies to many other sturgeon species as well.
