Too bad it won't biodegrade as a Chestnut would be. I have found keels and ribs of old wood canvas canoe that are decomposing ala dead mammals.

Even many plastics labelled as bio-degradable just break down into very fine pieces in a short space of time.

Arctic sea ice polluted with microplastics

Pollutants may wind up in Arctic food chain as climate warms, ice melts

CBC News Posted: May 30, 2014


Arctic sea ice has sopped up and stored large quantities of microplastic pollution from populated areas in the south, a new study has found.

Microplastics are tiny pieces of plastic from microscopic to fingernail-sized that have been found polluting oceans and lakes around the world over the past decade, but not so far north as the Arctic Ocean. Scientists are concerned about them because they tend to suck up and concentrate other pollutants in the environment, which enter the food chain when animals swallow microplastics.


While much of the sea ice in the past has stayed frozen for many years, locking up pollutants and sediments trapped in them, more and more of that 'multi-year' ice is melting as the Arctic warms as a result of climate change.
