Marty the Mussel
Meet Marty, a tiny freshwater mussel who spends his days in the riverbed quietly filtering water and helping keep his home clean. When a “green problem”, eutrophication, begins affecting the river, Marty introduces readers to his underwater world and explains why he could use a little help.
Through Marty’s story, young readers learn about freshwater ecosystems, wildlife, and real-world environmental challenges in an engaging and accessible way. The book also includes a glossary of key terms and a reading comprehension section to support learning and encourage critical thinking.
