It's not just seashells washing up on New Jersey shores.

FOX's Chris Foster reports:

A keg of beer, sports equipment, a container of birth control pills, toilet bowls, a mattress, a vacuum cleaner, a size 13 sneaker: All found on beaches in New Jersey by clean-up volunteers.

They go out twice a year. The head of the Clean Ocean Action Environmental group says, it all goes to show how careless and wasteful some people can be.

Some of the stuff was left on beaches, some fell or was tossed off boats, some came up from sewers after heavy storms.

Those volunteers picked up more than 332,000 pieces of debris last year around half of it plastic.
