Hawaii only needs to focus on Self-Sufficiency, Local Production and the Aina for the Kamaaina. Hawaii can fairly easily become 90% vegetable and fruit independent, rather than the 90% import dependent it is. Focus on local production for local needs, rather than trying to solve Global problems. There is tremendous opportunity for self reliance. The Japanese are starting to use large scale solar panels on man-made ponds and dual use with farms below the panels, http://newatlas.com/floating-solar-power-plant/37156/  , one is for growing shiitake mushrooms, about $15 per pound, usually needing to be collected from forests, almost tastes like ono beef, https://www.japantoday.com/category/technology/view/shiitake-mushrooms-grown-under-290kw-of-solar-panels  . This is electric power and food supply together, pure profit after the installation costs. The Vertical Farms under solar power panels can be mostly robotic tended, using drip irrigation, no pesticides, filtered ventilation.
