A glimpse into Azerbaijan's massive offshore oil city

Oil from Azerbaijan accounts for less than 1% of global reserves today, but the Central Asian country once played a major role in fueling the Soviet Union. The symbol of this production might was the world's first, and likely only, floating oil city: Neft Dalar - a network of 2,000 oil rigs connected by almost 200 miles of drivable causeways - rising out of the Caspian Sea. Host Marco Werman spoke to documentary filmmaker Marc Wolfensberger about the oil city which is being reclaimed by the sea around it.
