In marine environment, many animals confuse the plastic littering the oceans for food including sea turtles. Once in these animal bodies the plastic accumulates, and the chemicals can cause excess estrogen to be produced, which has led to discoveries of male fish with female sex organs. For sea turtles, the plastic blocks their digestive tract and the food that is trapped releases gases that render them buoyant, and unable to dive for food.
