Your days are numbered. Even though you’ve still got food and water, you know it won’t last forever. A day will come when you grow hungry but realize it’s harder to find crabs than it was before. And the coconut trees will look a little more bare. And the realization will set in that there is absolutely nothing you can do about it. The island holds all the power, and you are simply a pest feeding off of all its resources.
And when you die, the coconuts will continue to grow, and the crabs will repopulate. You may be mortal, but the island lives on forever. So you hatch a plan to get yourself off of this island once and for all. You feel a cool breeze from the Pacific tide and gaze up at the night sky. “I know you can change the tides and I know my fate is in your hands, but you’re not the boss of me anymore.” The dryness on your tongue goes away and you crack an evil smile.
