This program focuses on some of the ocean’s great migrators and relates one of humanity’s most important conservative victories: the recovery of the humpback whale. In the Dominican Republic, scientists are trying to solve the mystery of this species’ migratory routes. But new dangers, such as plastic pollution, now threaten the health of our oceans. A new “garbage patch” was recently discovered in the middle of the Atlantic Ocean. And now in the Pacific, albatrosses mistake pieces of plastic for food and feed over five tons of it to their chicks every year. .
