Despite your sarcasm and expertise with a ruler, your simplistic transportation assumptions are incorrect.
The vast majority of the ships arriving in Hawaii are coming from the U.S. west coast. Go to the harbor and check. There generally isn't enough shipping volume in any one particular commodity to justify eastbound traffic stopping in Hawaii on the way to the U.S. Most everything you see on the shelves in your grocery store came from the U.S. And a large percentage of the stuff from Japan, Taiwan, China, et al, come to Hawaii via the U.S. west coast.
Most environazis I challenge rarely consider the true costs of their choices. The true benefit often is not to the environment, but to the egos of the players. All the folks who think they're doing GOOD by home recycling do not stop to think of the environmental costs of having an extra set of garbage trucks driving around town, the second being dedicated solely to collecting the recyclables. The boneheads who hounded McDonald's into replacing the old styrofoam clamshell containers with cardboard because the former do not biodegrade as quickly failed to consider that NEITHER material degrades quickly once buried in a landfill. And the paper-producing process is many times dirtier than the styrofoam process. But this doesn't matter to these people. It's perception first, reality a distant second.
Wayne may be a bit caustic in his remarks, but he's absolutely right about one thing: If you really want to help the environment, get the hell off Hawaii. Stop polluting a delicate tropical environment while simultaneously placing huge burdens on the world's transportation systems relative to the rest of us.
Your environmental sensitivity is noble in spirit, I suppose, but it's only feel-good environmentalism when you examine it more closely. If it makes you sleep better at night, good for you. But it doesn't give you sufficient credibility to preach.
