Some years ago I was stalking on the South Downs and saw through the trees what at first sight looked like the rusted remains of an old oil drum.

When I got closer I found it was the rib cage of a very big Fallow Buck that had rolled onto his back.

Resting on his back bone was a fist size lump of compacted plastic that I suspect had caused his demise.

If in substituting steel for lead we also have to change from fibre to plastic we could well be moving from a theoretical problem to a real one,
