Guam has a population that is primarily Chamorro (37.1%) and Filipino (26.3%). The economy relies heavily on tourism and U.S. military spending. During World War 2, Guam experienced two major battles in 1941 and 1944 that still impact the island today through unexploded bombs and mines. Invasive species like brown tree snakes that were accidentally introduced have damaged the local ecology. Major typhoons like Paka and Omar in the 1990s caused extensive damage. Cultural sites to visit include Talofofo Beach, Two Lovers Point, and Chamorro Village.
