One of the areas of the world with the widest range of endemic biodiversity remains virtually unknown to many people. Known as Wallacea, it is located in the coral triangle within the Pacific ring of fire, and is home to many unique species both above and below the water. One hundred and fifty years ago, this area was explored by the British naturalist, Alfred Russel Wallace, for which it is named. Based on his experiences throughout the Indonesian archipelago, Wallace independently proposed the theory of natural selection and evolution. During his eight years in these islands, he identified many new species for the first time. Much of the habitat Wallace explored and the oceans surrounding these areas is increasingly under threat of destruction. This film, which is a slightly shorter version of "Life on Wallace's Line" highlights the biodiversity found in the oceans of Wallacea and the efforts of a few individuals to protect these fragile ecosystems.
