The author goes for a broad view in both wide-angled illustrations of litter floating or washed ashore and in adding notes about ocean currents, the value as well as hazards of plastics, and other related topics to his urgent message that our oceans are in trouble. A set of activities and organizations at the end adds fresh incentive for young recyclers and eco-activists to get off the stick. . . . An awesome odyssey that also makes a telling point, both worthy of repeated iterations.
