Brought for the Dinner Table: The Tragedy of Red Swamp Crayfish and American Bullfrogs

Introduction | The Justification Called "For Consumption"

If it is for food, it cannot be helped—

that line of thinking often ethically justifies "violence against ecosystems."

Both the red swamp crayfish and the American bullfrog
were lives originally brought in for the dinner table.

However, as a result, instead of being eaten, they were released into the wild, multiplied, and became entities that threaten other lives.

This story is not just another episode of the "invasive species problem."

It is a microcosm of ecosystem ethics, showing how human goodwill and desire can unconsciously invade nature.

Chapter 1 | The Import of Bullfrogs: The Illusion of Frog Legs

At one time, there was a movement in Japan to farm bullfrogsto export them as ingredients for French cuisine.That is when the red swamp crayfish was introduced from America.

The purpose was simple:

• Put crayfish into the farming ponds

• Utilize them as cleaners to eat leftovers and algae

• They would also serve as food for the frogs

• The balance of the ecosystem would be maintained (or so it was "thought")

But in reality—

• The crayfish escaped and spread nationwide

• They established themselves in ponds and rice paddies

• They became creatures that devoured aquatic plants and other small animals, drastically changing the ecosystem

And the frog export business, the main goal, failed.

Only the crayfish were "left behind."

"Lives brought in to be eaten

ended up on the side of destroying nature without ever being eaten."

Chapter 2 | The Excuse of Consumption: The Invasion of Life Without Boundaries

"It was for food" is a frequently used excuse.

• Not just cows, pigs, and chickens,

• but rainbow trout, largemouth bass, mongooses, bullfrogs, red swamp crayfish...

• All were brought in with the "human stomach" as the justification for their presence.

But there was no imagination for what would happen "afterward."

• What happens if they escape?

• Who takes responsibility if they multiply too much?

• Who realized that those lives might threaten other lives?

Consumption can only become ethical if the "structure after eating" is designed as well.

Otherwise, it is nothing more than"an excuse to ravage nature."

Chapter 3 | The Weight of the Act of "Bringing In"

Red swamp crayfish have come to be legally regulated as an invasive species.

But that is not because they are "evil."

Rather, the"structure where humans took no responsibility"was the real problem.

• Brought in with good intentions

• Escaped

• Multiplied

• Destroyed

• No one takes responsibility

This sequence is the blueprint for the structural ecological violence of modern society.

Conclusion | Transporting Life

Life is not a commodity.

If it moves, it changes its surroundings.

If it settles, it displaces other lives.

"This is just an ingredient."

Behind the lightness of those words,
many lives lose their place.

Supplement | To the Nameless Responsible Parties

There was no malice in whoever brought the crayfish in.

Even so, the ecosystem of Japan's rice paddies has now been altered by that "import" from back then.

Therefore, what we should ask is not
"who is to blame,"
but rather the question of"who designs the structure when creating a flow of life?"
