1. Spanning an astonishing 1,600 miles, the Great Barrier Reef is the largest living structure on the planet. It can even be seen from space.

2. The Rockall — a 30-meter-wide rock protruding from the ocean 290 miles off the coast of Great Britain — has had less than 20 humans stand upon it throughout history.
