Certain animals are thriving while others are disappearing for mysterious reasons. To solve this riddle, mammal and bird specialists set up camp on these rugged islands that are constantly lashed by the Southern Indian Ocean lows in order to place an array of tagging devices on penguins, elephant seals, albatrosses, orcas and other large animals. The resulting data reveals a number of unexpected consequences of human activity that affect the birth and survival rates of ocean wanderers. Some scientists propose and implement a range of remedies.
