Hawaii is one of fifty states of the U.S. and covers the Hawaiian Islands, a volcanic archipelago consisting of eight major islands, several atolls and numerous smaller islets. Hawaii became a state of the United States in 1959. Prior to that it was the Territory of Hawaii (1898 to 1959) and originally the Kingdom of Hawaii.

The majority of the environmental issues affecting Hawaii today are related to pressures from increasing human and animal population in the limited separation space of the islands.
