They have plenty of food. I've been to Hawaii and I've hiked that trail in Nāpali Coast State Wilderness Park. It used to be occupied until the 1940s by native Hawaiians and there are still many fruit trees growing wild on that coast. The land is very fertile and they will have no problem feeding themselves and growing marijuana. And there is plenty of fish in the sea for protein. If I was a bum and had nowhere to go that would be a place I would go.
That being said, if Hawaii ever gets cut off for a few months they're gonna be eating one another. It will be haole for dinner.
Don’t be too sure, I live right next to Parker Ranch, the country’s second or third largest privately owned cattle ranch in America. We have lots of cattle, pig, and goat ranches nearby.
Plus good hunting. Wild Goat, sheep, pig, turkey and chickens et al, running everywhere.
There are lots of farms in the area also.
The island bigger than Connecticut and only 200,000 year round residents, nobody will go hungry here.
We are not the Hawaii you see on the TV shows.
I’ve been “stuck” at Tahiti Nui when waiting for the water to go down to cross the bridge.
Squatters can get a few bucks picking snails off the taro and harvesting when it comes time. A strange place but fun if you’re accepted by the locals.
