If you were watching television this week you may have seen this clip of a taste test for hamburger meat grown in a “test tube” in London discussed here. The meat was grown from stem cells from existing cows used to grow 20,000 strands of tissue. Costing more than $330,000 to make, with funding by google Co-Founder Sergey Brin, the day where this will be available at your grocery store or served at your fast food franchise is far away. But it may come sooner if we conclude that there may be a moral duty to develop and eat this kind of meat rather than animal-grown meat and press our governments to start funding this work. What is the morality of test tube meat consumption?
Sometimes narrative can be a way into ethics so consider this bit from one of my favorite novelists (and Canadian public intellectuals) Margaret Atwood from her novel Oryx and Crake. She imagines a dystopian future that includes the the consumption of “Chickie Knobs” in one scene:
“This is the latest,” said Crake.
What they were looking at was a large bulblike object that seemed to be covered with stippled whitish-yellow skin. Out of it came twenty thick fleshy tubes, and at the end of each tube another bulb was growing.
“What the hell is it?” said Jimmy.
“Those are chickens,” said Crake. “Chicken parts. Just the breasts, on this one. They’ve got ones that specialize in drumsticks too, twelve to a growth unit.
“But there aren’t any heads…”
“That’s the head in the middle,” said the woman. “There’s a mouth opening at the top, they dump nutrients in there. No eyes or beak or anything, they don’t need those.”
To be clear the test tube meat unveiled earlier this week is not a Chickie Nob, it is grown from stem cells rather than being a cow with extra parts and brains missing (Atwood is silent on some characteristics of the Chickie Nob that may matter ethically such as whether it feels pain or is sentient), but I think many will react to the test tube meat the same way: disgust. Some in bioethics, like Leon Kass, think there can be a “Wisdom of Repugnance.” In my own work I have been a persistent skeptic on this theme. For me repugnance and disgust are good and should be cultivated as reactions for that which we deem immoral, but should be broken down and overcome for those things which we conclude are morally worth pursuing. Thus repugnance is a tool whose proper deployment depends on prior moral conclusions. In the case of test tube meat, whatever repugnance we feel is one we should get over and media, government, etc, should help us do so.
