When fish and other marine species mistake the plastic items for food, they ingest the particles and pass toxic chemicals through the food chain and ultimately to our dinner plates.

Ocean acidification, rising ocean temperatures, declining sea ice, and other environmental changes interact to affect the location and abundance of marine fish, including those that are commercially important, those used as food by other species, and those used for subsistence.16, 17,18,122,19,20,21 These changes have allowed some near - surface fish species such as salmon to expand their ranges northward along the Alaskan coast.124, 125,126 In addition, non-native species are invading Alaskan waters more rapidly, primarily through ships releasing ballast waters and bringing southerly species to Alaska.5, 127 These species introductions could affect marine ecosystems, including the feeding relationships of fish important to commercial and subsistence fisheries.
