The end of seafood for humans is bad enough—but what nobody in the mainstream media appears to be mentioning is the much wider impact that this would probably have on the environment as a whole. Breaking a link in the food chain inevitably creates serious problems within an ecosystem which take a long time to resolve themselves. 

Even if this news only refers to what might be called commercial species—which is by no means certain—the fact nevertheless remains that the range of species consumed by humans has expanded considerably over the last few decades. How many people in the 1960’s ate shark or Orange Roughy (a deep-sea fish)? Also, many of the species which human beings commonly eat such as tuna and halibut are high-level or top-level predators which help control populations of lesser fish—and removing a predator from the food chain often results in an explosion of the prey species which can create further problems down the food chain. However, if these reports don’t refer simply to commercial species, then the impact is potentially even greater since other fish are not the only top-level predators for the ocean—many species of birds and animals exist primarily or even exclusively on seafood, and it’s reasonable to assume that a collapse of seafood species would result in a collapse of these species as well, and this would inevitably have an impact on land-based as well as water-based food chains.

It’s a lot worse then just the loss of seafood. If we kill the oceans we kill ourselves. Jacques Cousteau pettioned the government, warning about this over 30 years ago. We are too short sighted and greedy as a species.
