This study aims at discerning the most prevalent threat posed by marine debris to Hawaiian green sea turtles. The hypothesis, that entanglement in stray nets and fishing lines most seriously endangers sea turtles, is proven false through data collection which indicates a much greater risk of ingestion. This paper includes information on the variety of threats to the continued existence of sea turtles, as well as data on the amount of debris which washes up onto Hawaiian beaches.
This project examined the prevalence of small plastic particles in the coastal zones of the big island of Hawaii and its potential effect on marine animals. We hypothesized that the ratio of plastic to plankton would be 2:1. Samples were obtained on the east and west sides of the island, and the plastic and plankton content was analyzed and compared. This experiment was a stepping-stone to other experiments to be implemented on a larger scale, and it will lead to a positive impact on the lives of marine animals.
Sustainability was brought into focus as this paper dedicates its efforts to provide supportive research towards an energy independent State of Hawaii. While assessing if wave power would have been a feasible solution for off shore development on the Big Island, resources such as bathymetry models, interviews, comparison methods, and research into government documents were used to discover the possible solution that the Big Island could be an energy independent state. An assessment of the practicality of the proposed method has been considered a feasible solution for the Big Island, but further research indicates that Wave Energy is not necessarily the most efficient resource. Diversifying the renewable resources such as ocean thermal energy conversion and wave energy conversion would allow greater potential towards a sustainable economy.
In this paper, the ability of macadamia crops to encourage significant economic growth with limited environmental impact was investigated. Through the use of on-site research involving interviews with several experts at various locations throughout the island, this hypothesis was tested against a similar potential posed by other crops, prospective growing methods, and general climate of the Big Island. Encompassing everything from details about the macadamia nut tree to its major producers, the macadamia nut was ultimately found to be unable to meet this goal. However, there is the potential for similar research to be conducted in the future that could hopefully bring improvements to the agricultural industry of the Big Island of Hawaii.
The research in this paper aimed at investigating the macadamia nut’s viability as a major crop in Hawaii. The findings show that macadamia nuts are not the most sustainable crop, nor the most profitable in Hawaii. The farming of macadamia nuts is an inefficient use of land, and the price at which the nuts sell do not generate enough revenue to recover costs from production.
This research looks at lava flows and their influence on the urban development of Hawaii’s Big Island. Research through the United States Geological Survey indicated that because lava flows were a natural risk, urban development and real estate would avoid these hazards. This proved to be incorrect during field research, as observation indicated that urban planning developed right on top of some of these hazardous areas. This paper will look at volcanic risks, population density, soils, culture, and urban development to decipher reasons for development on these hazardous areas.
