In a letter to Dagens Nyheter, Rolf Norén expresses his thoughts on the ethics of eating fish, suggesting that consumers should reconsider the moral implications of their dietary choices. He points out that while vegetarianism and veganism originated from a desire to avoid animal cruelty, there remains an inconsistency regarding fish consumption. Many individuals who abstain from eating mammals like cows and pigs often justify eating fish, neglecting the fact that research indicates fish have the capacity to experience fear and react to threats.

Norén emphasizes the need for awareness in conversations about dietary ethics, remarking that fish should not be exempt from the moral considerations that apply to other animals. He challenges the notion that consuming fish is a guilt-free alternative, urging those who claim to be ethical eaters to confront the reality of fish suffering. The letter adds to the growing discourse on animal rights and the ethical treatment of all living beings, advocating for a more uniform approach to dietary choices that includes fish within the same moral framework as other animals.

The implications of Norén's letter extend beyond personal dietary choices, reflecting a societal shift towards greater consideration of the welfare of all animals in the food industry. By raising this issue, he contributes to an ongoing dialogue that may influence public opinion on what it means to eat ethically. The writer's call to remove the 'halo' from those who consume fish alone speaks to a larger movement towards compassion and awareness regarding dietary habits and the impact they have on all forms of life.
