UK Establishes World's Largest Marine Reserve in South Pacific Pitcairn Islands

Only about 1% of the world's oceans are protected in reserves, but this number is steadily growing thanks in part to the United Kingdom. Tucked inside the UK's recent budget announcement was the bid to protect 322,000 square miles (830,000 square kilometers) around the Pitcairn islands in the South Pacific ocean from overfishing and seafloor mining. This equates to the largest contiguous ocean reserve on the planet - larger than the entire state of California - and will go a long way to protecting what some consider one of the most pristine places on earth.

Watch this video about the 2012 expedition to the islands that helped pave the way for this monumental achievement.
