Whether for the sake of the fish or for the sake of sustainability, we all need to make the right choices in our eating habits.
From food.change.org:
If you want to know who's responsible for decimating the world's oceans, look no farther than your local supermarket. Throughout the world, grocery stores and restaurants continue to sell threatened fish species like Chilean sea bass, shark, bluefin tuna, and orange roughy, just to name a few. The situation's gotten so bad that experts say 75 percent of the world's fisheries have been pushed beyond their sustainable limits, while nine out of ten of the seas' large fish species have disappeared. At the rate we're going, years from now there really won't be other fish in the sea.

Worldwide, fish populations are collapsing under our demand for their flesh, as well as from other human-created pressures and threats.
As if our trashing of the oceans weren't enough, as though the Great Pacific Garbage Patch, the Atlantic Garbage Patch, and the other garbage patches weren't enough, as if our stupid pertoleum demands leading directly to the BP oil gusher that destrying the Gulf as we speak weren't enough, we are also, through human pressure, driving dolphins in the Mediterranean toward extinction via more than 700 fish-farm pens dumping concentrated waste into the sea and the practice of some countries of dumping raw sewage into their rivers and the Med.
From New Scientist:
Gonzalvo should know. He used to work in what he calls "paradise on Earth" - the waters surrounding the Greek island of Kalamos. He was there to witness the crash in population of the common dolphin (Delphinus delphis) from 150 animals in 1996 to almost none in 2007. Tuna, swordfish and other large fish species declined over the same period (Endangered Species Research, DOI: 10.3354/esr00103). "When the common dolphins' food disappeared as a result of overfishing, the dolphins vanished," says Gonzalvo.
Industrial fishing is banned in the Amvrakikos gulf as it is a national park. Yet it is still becoming increasingly degraded. Like many parts of the Med, there is no sewage treatment, so raw waste is pumped directly into the water. The gulf also contains 24 fish farms with an estimated 710 fish cages between them, each producing nitrogen-rich waste, and a number of rivers with high nitrogen run-off in the form of fertilisers flowing into it. Add this together and eutrophication is a major threat: the water is murky and oxygen levels decline to near zero below 20 metres.

My personal concerns involve the damage that we are doing to our oceans and to the world, our pursuit of the extinction of so many species of fish, and the rights of cetaceans.
Please. Think about the choices you make.
