It's been estimated that at the time of Captain Cook, there were more than 200,000 pure Hawaiians in the islands. Now, because disease took its toll on so many early Hawaiians and because of inter-marriage with other racial groups, there are fewer than 15,000.
With this relatively small number of Hawaiians left to carry on native traditions and speak the language, the cultural heritage of the indigenous people of Hawai'i was in danger of being lost. However, in the past 25 years or so, there's been a great revival in learning about Hawaiian culture and the language. 
In fact, a law was passed in 1987 making Hawaiian an official state language. The mandate also sought to promote the study of Hawaiian culture, language and history, and the Department of Education established the 
Hawaiian Language Immersion Program.
