what does unesco do for world heritage sites
World Heritage Site The sites are intended for practical conservation for posterity, which otherwise would be subject to risk from human or animal trespassing, unmonitored/uncontrolled/unrestricted access, or threat from local administrative negligence. Sites are demarcated by UNESCO as protected zones.[1] The list is maintained by the international World Heritage Program administered by the UNESCO World Heritage Committee, composed of 21 UNESCO member states which are elected by the UN General Assembly.[2]
