Eating fish causes sea environment issues

ゴーストネット、亀environment issues

I wasn’t a favorite person to eat meat, but I loved grilled fish and boiled fish.

However, nowadays, when I look at fish, I think of the environmental problems of the sea and the lives of lost sea creatures that human did not plan to catch, so I I can’t buy and eat fish.

We now have a variety of problems, including overfishing, ghost nets, and marine pollution from the fuel of fishing vessels.

Here, I would like to consider the environmental problems of fish and the sea.

Overfishing (Japan)

The world’s largest wholesale market for fish from every sea is in Tokyo. (Old Tsukiji)

Hundreds of thousands of marine life are consumed in a year. The population change from 1950 to 2014 is Pacific bluefin tuna remaining 5%, shark remaining 10%, and cod remaining 5%. (Quote: Sylvia Earl Marine Biologist)

Several millions of sharks are cut out every year and thrown into the sea.

This way of exploitation is a factor that disturbs the ecosystem.

Also, the fish called Menhaden, used to swarm so large that it obstructed our view. However, it was captured by a huge machine such as a vacuum cleaner, and the number has fallen sharply. This is to feed the chicken. And Menhaden is rich in oil, so it is also overfished as a supplement of Omega 3.

In today’s era, mass production is carried out as the world population grows. The same is true for fisheries.

Many lives to be sacrificed

カメ、海の環境問題

Using a huge net, unnecessary big fish, dolphins, sharks, and even turtles get caught in the net, killing them.

For every 1kg of fish you get 5kg of unwanted organisms on the net.The huge net catches creatures indiscriminately.

In the sea, amount of predator has dropped by 90%.

At one sea location, a large number of fish floated in the sea.

It was a carcass of fish hurt by a net. Those that are damaged in the net are thrown into the sea like this.

Overfishing problems in fisheries

ロープで縛られた魚

It is said that fish will disappear from the sea in 2048 due to overfishing. (according to a paper published in the 2006 American scientific journal “Science”)

No one is keeping the catch quota set by scientists. I’m catching it without leaving anything.

It is said that 80% of the world’s commercial fish stock resources are underdeveloped.

In less than 200 years, we have destroyed the nature that the earth has built up in 4 billion years.

The sea is a great mother. The birthplace of all life. We humans are our own faces, polluting the sea, overfishing, and extinct fish.

The sea lions were separated from the flock and were crying all over the net.

Ghostnet problem

ゴーストネット、死

Fishery overfishing creates the problem of ghost nets.

Ghostnet was created to represent a deliberately abandoned or accidentally dropped net floating in the sea and entwined with whales, seals and turtles. Is a term.

Estimated 100,000 marine animals are strangled, suffocated or injured by plastic fishing nets each year.

ゴーストネットが絡まって死んだ魚

Slat’s team of scientists released a comprehensive report in the Scientific Report on March 22, 2018 that 46% of the Pacific litter belt is fishing nets, and most of the rest is rope or Oyster culture pipes, eel traps, crates, baskets and other fishing gear.

Scientists also speculate that 20% of the debris is due to the 2011 tsunami in Japan. (Quote: Foodfacts)

Sea pollution from fisheries

海と魚、サンゴ礁

When fishing, we use ships with huge motors. A huge amount of fuel is flowing into the sea to turn this motor.

When you fish, the boat will also pollute the sea.

Fishers are the largest contributor to marine pollution from oil spills.

Problems in the aquaculture industry

乱獲

Since anchovy is not for human consumption, but for feeding salmon, sea bream, and sea bass, a large amount of anchovy is caught from the sea. 1kg of cultured fish requires 4kg of anchovy.

So what do we do next if the sardines are extinct?

Mediterranean aquaculture is expanding its business with official grants from EU countries and there are no precautionary measures for the conservation of species.

Overfishing heaven is the ship’s graveyard(The Ocean)

When the catch in the sea decreases, the fishing boat will head to the ocean.

The open ocean occupies two-thirds of the ocean and is a free area. In other words, the first one wins.

In West Africa, vicious shipowners send poor fishermen to the ocean. Given a tattered and fragile ship, food rarely reaches the ocean. Therefore, there are many people who lose their lives.

Natural Harbor of Mauritania has hundreds of broken ships and is the graveyard of the ships.

Illegal fishing is common in Africa, where fish are transferred from illegal fishing vessels to legal fishing vessels and sold to the international market. Illegal fishing vessels catch an estimated 26 million tons, accounting for one-quarter of the world’s catch.

Money and sea

海

Atlantic bluefin tuna is endangered. But this tuna in the Mediterranean is legal. Tuna is a high-class fish, and large 300 kg class tuna can be traded for more than 4 million yen.

Profit controls the sea.

The cause of the rapid increase in jellyfish is the sharp decrease in this predator, tuna. This is a phenomenon occurring all over the world.

The waters of 400 coastal areas around the world are “dead areas” where marine life cannot survive.

Summary

ビーチ、海

Did you find any surprises in this article for the first time?

Don’t forget the shock and emotions at that time. Remember when you see or buy fish. We can’t see the ocean conditions or the fishing scene, but the above is true and what is actually happening.

Because humans are at the top of the living world, I think we should take action to preserve the species, rather than exploiting and extinct living creatures.

Protein can be obtained from plant foods other than fish. Omega-3s found in seaweed and fish can also be taken from flax seeds and vegan supplements. Now you can choose not to eat fish.

Our future choices will determine all our destiny on Earth.

“Just because you can’t do it perfectly doesn’t mean you have to do nothing.”

When I heard this word somewhere, it really moved me. It doesn’t have to be zero or 100%.

However, I thought don’t rest on it just because it’s not 100%.

If you want to protect the sea, consider options to reduce fish consumption in your daily diet to reduce fishery production even a little.
