  5. Andros • Andros is the largest island in the Bahamas, it is sparsely populated • The island has an extensive cave system that captures rainwater • Three to four million gallons of freshwater are transported by tanker every day to nearby Nassau, which has a limited supply of freshwater and a few desalinization plants

  6. Economy • Most of the natives are fairly poor • The primary drivers of the economy are an American naval base and tourism, much of which is directed towards sportfishing • Anglers are drawn to the large expanse of shallow flats surrounding the island, as well as the nearby Tongue of the Ocean, an expanse of very deep water that harbors numerous pelagic species
