Most food scraps from our kitchen go out to a compost bin next to the back fence. The bin has been out there for years and it is populated by some sort of red earthworms — not sure what species, though I see Lumbricus rubellus and Eisenia fetida are candidates. There is lots of other life, seen and unseen, out in that bin, too. Armies of mites and other insects, the occasional millipede, and bacteria, fungi, and other unseen organisms by the millions or billions. Every day or two, I go back out there and throw whatever scraps we have to offer into the bin and stir things around with a garden fork. That was the prelude to the shot above.
Which reminds me: I got worms.
