We Need the Amazon Rain Forest

K-Gr 3--These books introduce readers to ecosystems such as the rainforest and ocean, explaining their importance. The text examines how these areas act as carbon sinks and details how they are affected by pollution and deforestation. There are also suggestions for how to help preserve these key natural resources. Colorful illustrations reveal howler monkeys, harpy eagles, sharks, and other wildlife. Some spreads must be turned sideways to show the various layers of the rainforest or the different zones of the ocean. Another illustration shows goldfish bowls stacked from the Earth to the moon to help students visualize how much water the oceans hold. A few pages also have inset images to show close-ups of phytoplankton and krill. A glossary and a list of selected sources appear in the back matter. VERDICT An engaging introduction to environmental awareness for primary grades.
