How can we best protect the polar marine environment against pollution? Leading scholars on environmental law, the law of the sea, and Arctic and Antarctic affairs here examine this important question. This book compares global, regional and national levels of regulation, and considers specific pollution issues such as land-based activities, the dumping of radioactive waste, and shipping in ice-covered waters. Developments since the establishment of the Arctic Council in 1996 and the entry into force of the Protocol on Environmental Protection to the Antarctic Treaty in 1998 are also discussed.
