[geo] A novel target for climate engineering? Fly larvae in freshwater

The gist: a particular species of fly uses methane to keep its larva near the surface in freshwater. That is about 2k to 130k larva per 1 meter2 of freshwater. But methane use by the larva increases in dirty water. So keep freshwater from becoming dirty e.g. agricultural run-off might decrease meth
