In this poetic informational picture book, a young pirate realizes that he is a little different from his fellow pirates: He's smaller, he looks different and thinks differently. With his unique set of skills, Peter decides he can make a big difference. He listens to his grandmother who tells him "give back to the earth instead of taking, that is the choice you should be making". Impressed by what she says, Peter focuses on the ocean. Follow along as Peter listens to the sea creatures and discovers the problems they are facing and learns what we all can do to make the planet a better place.
