After a recent trip to Hawaii where I saw plastic on many beaches, I would say that by weight, fishing nets make up the majority, but land-sourced trash is by far more numerous. There were some big tangles of nets in piles 2 feet high, but then there would be thousands of bottle caps, bottles, and random plastic trash. Some of it was identifiable, such as a plastic umbrella handle, others were just jagged pieces of white plastic. I also found a few pieces of melted plastic, which makes me wonder if incinerator slag is being dumped, maybe from ships.
