A shark sanctuary is an area that forbids commercial fishing operations from targeting and retaining caught sharks, including their fins. The first shark sanctuary was created by Palau in 2009. It was followed by Maldives, Honduras, The Bahamas and Tokelau. Every year, fishermen pull "up to 73 million" or "some 100 million" sharks from the world's oceans. The United Nations Food and Agriculture Organization (FAO) estimates that more than half of shark species are overexploited or depleted. Globally, 21% of shark species whose extinction risk has been assessed fall into the "threatened" categories, and 18% are "near threatened", while 35% lack sufficient data to decide, leaving 26% in the unthreatened category.
