Threats Terrorism may pose the greatest threat to tourists' safety in the Philippines, notably in the southern regions bordering Malaysia. The far-southern region is widely known as a no-go zone for foreign visitors. Areas surrounding Marawi and other parts of the island are considered unsafe due to violent activities of rebel groups which include the Maute Group and Moro Islamic Liberation Front (MILF). Certain militant Islamist groups such as Abu Sayyaf and Jema'ah Islamiyah are particularly dangerous, since they are responsible for the majority of recent attacks, which have included bombings, piracies, kidnappings and killings of foreign nationals if their government failed to pay the demanded ransom. The New People's Army of the Communist Party of the Philippines has been listed as a rebel or terrorist group by the Philippines and the United States. Other threats include cultural heritage destruction due to damage, demolition, or looting of heritage structures, and urbanization of younger generations away from indigenous traditions, causing various rituals and practices to fade away. Threats to natural heritage include mining, severe population growth, urbanization, introduction of invasive species, deforestation, water pollution, air pollution, climate change, irresponsible tourists, and a lack of initiative in proper waste disposal among poor brackets in society.
