National Geographic Speaker Series: Diving the Barrier Reef w/Erika Woolsey

Once a year, Australia’s most famous reef turns into a snow globe, as millions of coral polyps reproduce to send the next generation afloat. Don’t be fooled, however, as the display disguises that the Great Barrier Reef is under attack. Marine biologist Dr. Erika Woolsey shows through 360-degree photography and virtual reality video how scientists and citizens are fighting to protect the reefs of the world.
