Since most plastic tends to float, currents transport it to shore. Even in remote areas like Antarctica researchers are now finding plastic bottles, bags, and sheeting washed ashore. Marine animals sometimes confuse plastic items for real food - a fatal mistake. Ingested plastics can cause internal injury, intestinal blockage, or starvation. Seabirds are known to eat everything from small plastic pieces to plastic lighters and bottle caps.
Some birds even feed plastic debris to their young.
Sea turtles often mistake bags and sheeting for jellyfish, a favorite prey item. Even the great whales are victims - several have been found dead with plastic bags and sheeting in their stomachs. Sometimes an animal accidentally swims into a piece of plastic and becomes ensnared, unable to escape. Curious seal pups are often attracted to floating debris and become entangled. Birds not only become entangled in plastic connector rings and fishing line, but also use plastic as nesting materials, which can create death traps for their young.
