If, in a few years, you are suddenly overcome with a sense that there’s something fishy about the lettuce in your salad, you might be on to something. There’s a chance it was grown with fish poop.

“There’s no fish taste whatsoever,” Michael Amadori, a master’s student in ecological engineering at the State University of New York’s College of Environmental Science and Forestry, assured me Wednesday.

For now, Amadori is growing the futuristic lettuce in question as part of a science experiment aimed at closing the loop between the food we throw away and the food we eat.
