Take the Plunge: Sir David Attenborough, the British natural historian who’s well-known for his work on a wide variety of nature documentaries including the Planet Earth series, recently launched a free interactive virtual experience that guides viewers through the entirety of Australia’s Great Barrier Reef, which makes up 2,300km of its coastline. Watch video footage, learn about thousands of species of fish, and map your progress all from the comfort of your couch.
