Exxon Valdez Turns 20

摘要

Twenty years after the Exxon Valdez oil spill, little remains in Prince William Sound to remind the eye of 1989's striking images of oiled birds and sea otters, or of armies of workers in protective gear toiling to clean blackened beaches. Today, the waters of the sound are turquoise and the shorelines bristle with life, almost none of it human.rnBut researchers are still studying the spill's persistent aftereffects: Even as many species have recovered, others continue to struggle. Some may still come in contact with the oil that lingers, tucked away below the rocky surfaces of the beaches.
