Is tuna fishing bad for the environment?

Overfishing poses serious threats as loss of predators, like tuna, allows populations of prey species to expand. This then can lead to a destabilized food web and marine environment.

Is canned tuna unsustainable?
We’re Pulling Tuna Out Of The Ocean At Unprecedented — And Unsustainable — Rates. A new study finds that tuna harvests, including of some species considered “vulnerable,” have increased by an astonishing 1,000% in the last 60 years — a rate that some scientists warn is unsustainable.
Will tuna eat humans?
What about humans? Extremely unlikely. First of all because they normally feed in shoals, groups of 20, 30, 40, 50 different fish that all vary in size. And they generally follow herring, anchovy or sardine shoals themselves, where they can maximize their feeding.

Is pole caught tuna better?
Pole-and-line fishing is a simple approach to catching tuna with a hooked line attached to a pole (Majkowski 2003b). In itself, pole-and-line fishing for tuna is much more sustainable than the devastating longlines, which catch not only tuna, but many sharks and other marine creatures, as well as sea birds.
What would happen if bluefin tuna went extinct?
Scientists believe that the collapse of bluefin tuna in the Mediterranean Sea may lead to a sharp increase in the biomass of bentopelagic cephalopods, such as squid. This would negatively affect the sardine population.
