It is a maxim of ecology that "wherever there is something to eat, there will be something to eat it." At least I think it is: I may be remembering this line from the excellent novel Dune, uttered by the Imperial Planetologist Dr. Kynes as he lays dying in the deep desert, eyeing the hawks circling above him. In either case, the principle is sound. Anywhere on Earth, when anything dies and falls to the ground, it will get eaten, if only by microbes.
Just as there a chain of organisms on the production side of the food pyramid, beginning with clorophyll containing plants that convert sunlight into sugar and ending with peak predators like lions and humans, so there is a chain of scavengers that reduces the remains of all that dies back into its constituent molecules. Descending from the apex on what we might call the downslope of the food chain, we have large animals like hyenas and vultures, followed by smaller creatures that live on decaying flesh like crabs and ants, and ultimately the myriad microbes that slowly transform the less digestible bits such as bones and hair back into soil. The chemistry of systemic catabolism is just as fascinating as that of the more highly visible and valued systemic metabolism.

I feel that I have firmly joined Team Scavenger. I devote a great deal of time to seeking out resources unnoticed or undervalued by others. In fact, my family largely subsides on my local waste stream. That we live so well and so fatly is a measure of just how rich and bountiful that waste stream is.

Any food that we can't use - peels, skins, bones, and the like - or that we end up not eating because there is just too much of it - the lettuce that wilts in the back of my fridge before I can eat it; limp carrots and cucumbers; bread that has gone a little green - we give to our pig and our chickens. They are the second level scavengers, akin to lobsters or beetles.
And when all that refuse has been processed by my animal's digestive systems, we collect it once again and compost it. Enter the microbes. Our compost pile is rich, black, velvety and fragrant. Once a year, in springtime, our next door neighbor comes over in his tractor and collects some of it for his garden beds. Come next summer, some of it will make its way back to us in the form of sweet cilantro, ruby beets, plump squashes.
This time of year, as the world turns towards darkness and winter, I am especially conscious of and especially grateful for the quiet science of recycling that takes place in the sleeping earth. The dark side of the year is the time to contemplate the renewal that happens as we rest, as the dirt rests. So much grace happens in repose, so many vital processes are accomplished only in stillness. We are all of us, at least in this culture, so biased towards the light - toward action, towards growth and vigor, toward Yang, that we are blind to the necessity of decay. The alchemy of decay; of rot, of mold, of the mushroom and the slug. By such humble beings are we sustained, generation after generation.
Hail Yin, hail Kali and Hecate, hail Persephone, Isis, Osiris, Jesus, and all those good Gods and Goddesses who descend into the earth to rise again after three days, or seven, or nine. Hail the seed that goeth into the ground and dies, that it may live.
