The Cook Islands
Nan was living in the South Pacific Islands in Rarotonga. Through her career and passion for whales, Nan managed to successfully turn the entirety of the Cook Islands territorial waters — all 772,200 square miles of them — into a whale sanctuary.
Nan actually was the founder of the Center for Cetacean Research and Conservation on Rarotonga. Back in 2001 the Cook islands officially declared that the boundaries of their whale sanctuary would extend up to 200 nautical miles from shore. If whales could only speak they would thank Nan but there was a single humpback whale that caught her off guard.
