For young readers comes an imaginative guide to ocean plastics, filled with tips and tricks for identifying-and combating-pollution in our oceans. Inspired by biologist AnaPego's life's work, and filled with engaging science and colorful photographs, this foundational look at plastic pollution in the oceanexplains why it issuch an urgent contemporary issue. When she was young, Ana Pego didn't play in a backyard, but on a beach. She walked along the shore, looked at tide pools, and collected fossils. As she grew older, Pego noticed a new species at the seaside: plastic. She decided to collect it, study it, and give it a Latin name-Plasticus maritimus-to warn people of its dangers to our planet. Pego tells us how plastics end up in our rivers, lakes, and oceans, shares plastic's chemical composition and physical properties, and offers a field guide to help readers identify and understand this new invasive species in all its forms, from the obvious (fishing nets and water bottles) to the unfamiliar (tiny, clear particles called microplastics). Finally, she offers a critical look at our current "solutions" to plastic contamination and in her most important proposal-REVOLUTIONIZE-calls for deep changes in our habits, motivating young and old alike to make a difference, together. An artificial and almost indestructible species, Plasticus maritimus deserves to have its days numbered! Together, we can send it packing.
