It's all about the yuk factor. Americans don't want to eat bugs either. Or they'll spend tens of thousands of dollars draining an open air, million gallon water supply because somebody urinated in it, (never mind the constant exposure to bat and bird shit or general air pollutants of infinite variety). Astronauts recycle their urine and sweat as drinking water.
This is basically the same thing. Would I eat it? If I was hungry for meat and it cost the same, sure. Better than feeding a cow and killing it.
Somehow this feels like a Vonnegut plotline: population boom equals food shortage. Solution? Synthesize food from human waste matter. Absurd yes, but Japanese scientists have actually discovered a way to create edible steaks from human feces.
Mitsuyuki Ikeda, a researcher from the Okayama Laboratory, has developed steaks based on proteins from human excrement. Tokyo Sewage approached the scientist because of an overabundance of sewage mud. They asked him to explore the possible uses of the sewage and Ikeda found that the mud contained a great deal of protein because of all the bacteria.
The researchers then extracted those proteins, combined them with a reaction enhancer and put it in an exploder which created the artificial steak. The "meat" is 63% proteins, 25% carbohydrates, 3% lipids and 9% minerals. The researchers color the poop meat red with food coloring and enhance the flavor with soy protein. Initial tests have people saying it even tastes like beef.
Inhabitat notes that "the meatpacking industry causes 18 percent of our greenhouse gas emissions, mostly due to the release of methane from animals." Livestock also consume huge amounts of resources and space in efforts to feed ourselves as well as the controversy over cruelty to animals. Ikeda's recycled poop burger would reduce waste and emissions, not to mention obliterating Dante's circle for gluttons.
The scientists hope to price it the same as actual meat, but at the moment the excrement steaks are ten to twenty times the price they should be thanks to the cost of research. Professor Ikeda understands the psychological barriers that need to be surmounted knowing that your food is made from human feces. They hope that once the research is complete, people will be able to overlook that ugly detail in favor of perks like environmental responsibility, cost and the fact that the meat will have fewer calories.
