GO DIGITAL WITH ACHIEVE
Real people. Real stories. Real science.
Available for the first time with Macmillan's new online learning tool, Achieve, Susan Karr’s Environmental Science for a Changing World 4e uses an engaging, journalistic approach—real stories about real people—to show students how science works and how to think critically about environmental issues. Each module reads like a single, integrated Scientific American-style article with clear explanations of essential processes and concepts enhanced with beautifully designed infographics.
