How is eating fish bad for environment?

Question

Just wondering. What kind of damage having a can of 70 cent wild tuna does to the environment. It's dolphin free.

Answer 1

Hi. I believe the real issue is the manner in which the fish is truly caught. Even though the label says "dolphin free" that does not mean that dolphins, or other non tuna fish for that matter, were caught up in the process. If the label says "dolphin friendly" there is apparently some ambiguity there.  This site explains how the true meaning of the label "dolphin friendly" has changed in the past. Ultimately, the question comes down a few points: 1. What does the label mean? ... that may vary by label.   2. Do you trust that the fishing practices truly follow the label 100% of the time? 50% of the time? 10% of the time?

Answer 2

What does the price have to do with anything other than your wallet?

At the rate we are going, there will be barely any fish in the sea by the middle of this new century.

Well i heard Tuna Also is Endangered so that might be the reason but im not quite sure myself

Answer 4

Commercial fishing is wiping out biodiversity, as miles of nets sweep up all the fish in their path—and take coral habitats with them. Commercial fishers have devastated the ocean’s ecosystem to the extent that large fish populations are only 10 percent of what they were in the 1950s.

Fish farms are no better for the environment. The fish on ocean-based farms are plagued by parasites and diseases, which they pass to fish living near the farms. When foreign fish escape from their cages, they threaten the well-being of native fish species. Fish farms pollute coastal waters with massive amounts of fish f***s and require huge numbers of wild-caught fish to feed their captives.

If you eat fish, you are supporting an industry that plunders our oceans with no regard for the horrible pain and suffering that fish and other marine animals endure or for the diverse ocean ecosystem that is imperative to the survival of all underwater life. Scientists warn that the damage caused by the fishing industry is irreparable. If you care about the environment, leave fish off your plate and in the ocean where they belong.

Well, that's a good question.

the answer is overfishing and endangering species.

Right now the once magnificent "Beluga Sturgeon" is on the endangered species list as are many others.

Extinction of any animal or species has an impact on our environment.

Take out even an insect ( like the bee for instance) could be devastating to our crops , flowers and so on ( which is happening now).

Bad things come from extinction and bad things come from taking animals or insects out of their native environment IE the"Cane Toad" prob in Australia, the "Red Ant" prob in the Galapagos's etc etc.

Not good.

So although eating that tuna is pretty safe now, it may not be around for future generations.

Of course the problem would be easily solved if some animals and fish were given a grace period( protected) to let them reproduce.

It won't happen though.Not in our lifetime.

Best question of the year!

Answer 6

Your taking another animal's meal that doesnt have all the food choice you do as a human. Your helping scarce the ocean of fish, therefore more dolphines and other under water creatures are dying.

People have to go out and catch the tuna in they're boats. Often times they dont care about litering or other animals that get in their way.

Answer 7

um i really dont know but wouldnt it depend on the fish whether its canned as you said or like caught and just grilled?

i would htink that canned is bad for the environment because you have to use resources to make the metal can i guess....

Answer 8

It is no more dangerous or damaging than bulldozing and clearing forests, grasslands etc to make room for crop farms (or animals farms for that matter) IF you catch your own fish, using a line AND only catch what you need AND generally follow regulations designed to protect fishing grounds.

Eating of fish itself is not environmentally dangerous. However, the fishing industry is huge, money driven enterprise (as are most enterprises) and many violators of environmental laws slip through the system. Dynamite fishing is prevalent in poorer countries. So is poison fishing (using cyanide). Some shrimp trawlers use chains to drag on the bottom to disturb and make shrimp go up but they also destroy coral systems in the process. The huge tuna fishers use nets tens if not hundreds of miles long and they do trap  a lot of other fish and mammals including dolphins. Overfishing is causing some species to be pressured due to lack of prey or loss of habitat etc.

The fishing fleets themselves have been identified as one of major causes of pollution in the open ocean.

However, one of the most devastating practices that is destroying coastal fish stocks  in third world nations has nothing to do with fishing itself. it is the use and destruction of mangrove forests for firewood etc. Mangroves are nurseries for a lot of coastal fish species
