The book, "Tracking Trash", is mostly about objects, such as Nike tennis shoes or bath toys being thrown overboard, by accident, and Curt, the main scientist, making a great discovery out of it. Curt finds some most unusual ways to learn about ocean currents, like putting radars on Nike shoes and having them float in the ocean, and when they reach shore a beachcomber finds the shoe and reports back to Curt. To help him with this Curt uses OSCURS, a program that can tell, (depending an where you dropped the item), what day, month, and year it will find a beach. It also talks about recycling and how we should use the three R's, (reduce, reuse, and recycle), more often. It also says we underuse the last R, (reduce), it says we should often talk about the importance of reducing to our family.
