The PBS Kids Go! series 'Arthur' is helping kids get into Earth Day today with the launch of five brand new episodes about environmental protection, cultural awareness, and teamwork. 

The first episode airing is "Buster Baxter and the Letter from the Sea." In this episode, Buster discovers a message in a bottle on the beach while on vacation with the Read family and begins sending his own messages by throwing bottles into the ocean. Buster and Arthur ultimately learn that keeping the beaches and waterways clean is the real message.
