It may keep a few of the cars running a little longer, but it isn't likely to add much to exports, and the use of the land for this purpose leaves less for food.

wait just a minute here. peak oil is a huge problem yet Hawaii can probably produce some large amounts of sugar and that STILL doesn't matter? sugar cane can help people get around town, grow some crops AND you can burn it to make electricity. that's a big plus. I can't say I know much about how they grow food. I will say that everything costs more in hawaii because they are at the end of the supply chain. in the future they'll still get imports but they'll pay more for them than the mainland they they always have. while hawaii is dependent on someone else to grow their food the flip side is someone depends on hawaii not being able to grow food to make a livelihood.
