This paper makes disturbing reading. Various surveys have found that the enormous amounts of plastic found floating in the sea actually constitute much less than expected. Now there is evidence that larvaceans take in bits of plastic and excrete them in pellets dense enough to sink to the sea floor.
The big question is: do they just drop all the way down and lie there; or do fish ingest them as they are sinking; or perhaps sea bed animals eat them? If either of these occurs it means that we could also be eating them. (I rather like crab!).
Watch this space!
