Ten years ago Hurricane Katrina devastated the coast of Louisiana. Five years later the Deepwater Horizon exploded and spilled more than 200 million gallons of oil into the Gulf of Mexico, the worst ecologic disaster in North American history. Amazingly those aren't the worst things facing Louisiana's coastline today. It is that the state is fast disappearing. When on Earth Day 2010 BP's Deepwater Horizon exploded and sank many in Louisiana predicted it would change the state's coastline forever, both its economy and its people. How has the coast changed in the past five years?—Jon Bowermaster

Five years after BP's Deepwater Horizon exploded and sank in April 2010, has life returned to normal along Louisiana's coastline? Or has it been changed forever? When the well exploded we were putting the finishing touches on SoLa, Louisiana Water Stories, which we'd begun filming in 2008. That film captured a way of life in SoLa pre-spill that many now believe will never return. Since the spill we have returned many times, with cameras, to interview fishermen, scientists, politicians, environmentalists, and oil-rig workers seeking answers as to how the coast of Louisiana has changed. What really happened to all that oil? What about the dispersant used to push it beneath the surface? How has the spill impacted local economies as well as human health and the health of both marine life and the Gulf itself? Has Louisiana's coastline been changed forever?
