There has been a lot of interest in Breadfruit as a slow carb crop. A friend mentioned that demand exceeds current supply.
Anyway, I'm glad I got to see the fields of cane growing out of the bright red dirt on either side of the highway from Kahului to Wailea. I even made a wrong turn and ended up in the parking lot of that sugar plant-it was about the most industrial thing I saw on Maui.
I forwarded the OP to my friend from Global Manna. His opinion about the effects of cane on the Island biome were less fond.
