Through the magical adventures of daring Seb, children learn about the effects of plastic pollution and, more importantly, are enlightened as to the simple and practical ideas on how they can help prevent it. In this fun-filled book our strong, compassionate, female superhero Polly Planet (plus narwhals, albatrosses and a leatherback turtle) opens Seb's eyes to the challenges facing the ocean from plastic pollution and teaches her ways on how to overcome them. With Polly's guidance, Seb learns the ultimate truth: that her actions really can make a difference to the world.
