An Idaho veterinarian has had a brilliant idea. Deal with the manure from farms by feeding it to maggots, who use half of it to build their own bodies and break the other half down into a clean soil amendment. Then feed the maggots to rainbow trout.
Alas, this article from the Associated Press sensationalizes the process a bit, stating that it would involve feeding manure to trout. That’s a bit like saying that humans eat sunlight, since we eat plants that feed off of sunlight.
Never thought you’d see manure compared favorably with sunlight, did you?
