Oceanic Islands make up a sixth of all land on Earth. In the Pacific alone, more than 25,000 islands are scattered amidst the endless blue. From Hawaii's rocky mountains, to coral atolls of the Maldives, each hosting unique communities of life and species found nowhere else on Earth. Ecosystems that would not exist if not for the powerful forces that pulled these mighty rocks from the abyss. Volcanism, and tectonics.
