Title: Hawaii
Content:   The history of Hawaii's economy can be traced through a succession of dominant industries: sandalwood, whaling, sugarcane, pineapple, the military, tourism and education. Since statehood in 1959, tourism has been the largest industry, contributing 24.3% of the gross state product (GSP) in 1997, despite efforts to diversify. The state's gross output for 2003 was US$47billion; per capita income for Hawaii residents in 2014 was US$54,516. Hawaiian exports include food and clothing. These industries play a small role in the Hawaiian economy, due to the shipping distance to viable markets, such as the West Coast of the United States. The state's food exports include coffee, macadamia nuts, pineapple, livestock, sugarcane and honey. By weight, honey bees may be the state's most valuable export. According to

Title: Hawaii (island)
Content:  Sugarcane was the backbone of the island of Hawaii's economy for more than a century. In the mid-20th century, sugarcane plantations began to downsize, and in 1995 the last plantation closed. Most of the island's economy is based on tourism, centered primarily in resort areas on the western coast of the island in the North Kona and South Kohala districts. More recently, Hawaii Island has become a focus for sustainable tourism. Diversified agriculture is a growing sector of the economy. Major crops include macadamia nuts, papaya, flowers, tropical and temperate vegetables, and coffee beans. Only coffee grown in the Kona District of

No Hawaiian land was ceded in the agreement. At the treaty's expiration, an extension was negotiated that ceded exclusive use of Pearl Harbor to the United States. The treaty's most immediate result was an increase in new United States plantation owners. San Francisco sugar refiner Claus Spreckels became a prime investor in Hawaii's sugar industry. Over the term of Kalākaua's reign, the treaty had a major effect on the kingdom's income. In 1874, Hawaii exported $1,839,620.27 in products. In 1881, Kalākaua embarked on a world tour to negotiate with friendly 
Title: Ford Island
Content:  Sugar had been a major export from Hawaii since Captain James Cook's arrival in 1778. During the 1850s, the U.S. import tariff on sugar from Hawaii was much higher than the import tariffs Hawaiians were charging the U.S., and Kamehameha III sought reciprocity. As early as 1873, a United States military commission recommended attempting to obtain Ford Island in exchange for the tax-free importation of sugar to the U.S. At that time Major General John Schofield, U.S. commander of the military division of the Pacific, and Brevet Brigadier General Burton S. Alexander arrived in Hawaii to ascertain its defensive capabilities. U.S. control 
Title: Tourism in Hawaii
Content:   Hawaii is a U.S. state that is an archipelago in the Pacific Ocean. Of the eight major islands, Hawaii, Oahu, Maui, and Kauai have major tourism industries, while it is limited on Molokai and Lānai and access to Niihau and Kahoʻolawe is restricted. In 2017 alone, according to state government data, there were over 9.4 million visitors to the Hawaiian Islands with expenditures of over $16 billion. Tourism makes up 21% of the state's economy, with many of Hawaii's largest industries revolving around the constant flow of tourists. Due to the mild year-round weather, tourist travel is popular throughout the year. The summer months and major holidays are the most popular times for outsiders to visit, however, especially when residents of the rest of the United States are looking to escape from cold winter weather. The Japanese, with their economic and historical ties to Hawaii and the US as well as relative geographical proximity, make up the largest group of inbound international travelers to the islands, reaching 1,568,609 in 2017. The average Japanese stays only 5 days while other Asians stay over 9.5 days and spend 25% more.

Seeds yielded US$264 million in 2012, supporting 1,400 workers. , the state's unemployment rate was 3.2%.

Title: Overthrow of the Hawaiian Kingdom
Content:  Sugar had been a major export from Hawaii since Captain James Cook arrived in 1778. The first permanent plantation in the islands was on Kauai in 1835. William Hooper leased 980 acres (4 km²) of land from Kamehameha III and began growing sugar cane. Within thirty years there would be plantations on four of the main islands. Sugar had completely altered Hawaii's economy. The influence of the United States in Hawaiian government began with American-born plantation owners advocating for fair representation in the Kingdom's politics, owing to the significant tax contributions made from the plantations to both the Royal family and national economy. This was driven by missionary religion and

This treaty also guaranteed that all of the resources including land, water, human labor power, capital, and technology would be thrown behind sugarcane cultivation. The 1890 McKinley Tariff Act, an effort by the United States government to decrease the competitive pricing of Hawaiian sugar, paid 2 cents per pound to mainland producers. After significant lobbying efforts, this act was repealed in 1894. By 1890, 75% of all Hawaii privately held land was owned by foreign businessmen.
Title: Hanalei Pier
Content:  The wetlands of Hanalei Bay were used to grow taro by ancient Hawaiians. By the 1860s, the shrinking population of native Hawaiians was being replaced by ethnic Chinese people when their contracts expired on sugarcane plantations in Hawaii, such as the one directly to the north in Princeville. The new crop was rice, which was shipped to Honolulu to become the second largest export crop of the islands. After the annexation of Hawaii to the US in 1898, Hawaiian rice could not compete with rice grown in California and shipments declined. The pier was originally built of wood before 1892. In the early 1900s work began to extend the pier, and it was eventually
