Ok felt that while Chuck Nolan was marooned on this island and it was green and lush you saw no birds or rodents or any thing that would've fertilized this island. If there were coconuts what fertilized the Palm trees? I undestood that he was marooned however it was unbelievable that there were no frogs, snakes, birds or anything on that island that would've made it lush. Crabs and fish would not have been the only food resource!
