The striking two-tone graphics of this picturebook provide an innovative and uncomplicated depiction of an important part of contemporary life: sustainable development, including over-fishing, pollution, and industrialisation. A little boat voyages across the wide sea. An industrial trawler comes by, belching toxic black smoke into the clear sky. The sailor on the little boat does a small act of bravery, cutting at the nets of the trawler to release dozens upon dozens of fish back into the freedom of the water. The narrative provides an aperture for many different readers, including teenage readers, to contemplate the role of justice and equality in globalization and sustainable development. Although the focus is upon over-fishing, the text has clear application to explore the effect of humans on the climate and the need to ensure a sustainable future for all.
