This composite file photo shows an aerial view of Mallipo Beach (top) in Taean, South Chungcheong Province, covered with crude oil from a supertanker after it collided with a maritime crane on Dec. 7, 2007, and, at bottom, the same view of the beach on Dec. 5, 2017. The collision took place in waters off Taean, leaking 12,547 kiloliters of oil that subsequently hit the country’s pristine west coast, devastating fish farms and beaches. The western coast and sea recovered with the sacrifices of more than 1.2 million volunteers a decade after the country’s worst-ever accident of its kind. (Yonhap)
