On remote rural beaches the rubbish tends to have come from ships, such as fishing equipment used in the fishing industry. This plastic can affect marine wildlife in two important ways: by entangling creatures, and by being eaten. Turtles are particularly badly affected by plastic pollution, and all seven of the world's turtle species are already either endangered or threatened for a number of reasons. Turtles get entangled in fishing nets, and many sea turtles have been found dead with plastic bags in their stomachs. Turtles mistake floating transparent plastic bags for jellyfish and eat them. In one dead turtle found off in the Pacific more than 1000 pieces of plastic were found in the stomach. A recent US report concluded that more than 100000 marine mammals die each year in the world's oceans by eating or becoming entangled in plastic rubbish, and the position is worsening World-wide, 75 marine bird species are known to eat plastic articles.

Two studies on several islands off Jakarta Bay and islands further to the northwest in the Java Sea, reported that debris pollution on shorelines had substantially increased between 1985 and 1995 (Uneputty and Evans 1997b, Willoughby et al. 1997). Both studies noted that results implicated Jakarta as a major source of the debris. On 23 of the islands, it was reported that the total litter at the strandline ranged from not detectable to 29.1 items/m (Willoughby et al. 1997). Plastic bags, polystyrene blocks, and discarded footwear accounted for 80 percent of the items found.
