Hub-cap

This hub-cap has been there longer than we have, and every year, I guess, has red beans planted around it.
Actually, I think the farmers are probably right. They've been farming these fields for around 5000 years and may know more about mulch, compost, fertiliser etc than me. We sneer at the polythene sheeting, school text books, sneakers, bed-coverings etc (as well as the bub-caps, plastic flashings etc from the passing cars) and think that the farmers are really lazy. Recently, though, I was looking at some polystyrene that was further down in the strata and it was showing clear signs of disintegration! Another hub-cap, similarly futher down in the soil, may well be, as well, but there isn't enough of it to see to be sure.
I suspect that in another one or two thousand years the farmers will be nodding wisely to each other and congratulating themselves on the wisdom of their forefathers in not throwing away their natural resources.
