Plastic Meals for Seals

What happens after you dump your soda bottles, milk jugs, and yogurt containers into the ocean? Bite-size pieces of the discarded plastic can end up in the stomachs of seals and other animals in distant places. For years, scientists have been worried about the effects of various types of plastic garbage. Seals, for example, often get entangled in plastic netting. Now there's evidence that seals also end up swallowing plastic. Between 1990 and 1997, Harry Burton and Cecilia Eriksson collected droppings from two species of Antarctic fur seals that live along beaches on Macquarie Island in Australia. The two researchers found 164 plastic chunks in the 145 pieces of scat they examined. The irregular shapes and ripped edges of the plastic pieces suggested that they were once parts of larger objects, such as plastic containers. The seals probably didn't eat the plastic directly. Instead, they ate fish that had eaten the plastic after it had been broken to pieces by rocks and waves. The study shows just how far a little garbage can go.E. Sohn
