Coral reefs are vital to the culture and economics of Hawaii, and to the quality of life of the people who reside in the State and who visit it as tourists. The average person reaping these benefits has only a vague concept of the importance of the reefs, and a partial understanding of the complexity of the threats to these ecosystems. By playing the game, you will have a better understanding of the ecology of the coral reefs and effects humans have on the coral reef ecosystem. Enjoy the game.
