I have sailed many years ,many places - from Panama, Throughout the Caribbean, most East coast harbors, the St Lawrence Seaway and Great Lakes to Green Bay -- every single place had floating food waste and surely waste on the sea floor = every where there were boats there was trash in the water --- not always from boats I realize.
I am much more concerned over the Pacific Gyre.

As a restaurant owner in the USVI in the 70's I used to have fresh seafood shipped down from New England on Thurs. -- often sailing after closing Sun. night + Monday. We took the Cherrystones and Cotuit Oysters onboard to eat - and threw the shells overboard.
One morning a crowd of snorkelers were around us diving down and calling " all the shells are over here!"
We thought maybe the Tourism board would hire us to eat the seafood and spread the shells for the stateside tourists?
