Updated with the latest data from the field, Environmental Science: Systems and Solutions, Fifth Edition explains the concepts and teaches the skills needed to understand multi-faceted, and often very complex environmental issues. The authors present the arguments, rebuttals, evidence, and counterevidence from many sides of the debate. The Fifth Edition includes new Science in Action boxes which feature cutting-edge case studies and essays, contributed by subject matter experts, that highlight recent and ongoing research within environmental science. With an "Earth as a system" approach the text continues to emphasize Earth's intricate web of interactions among the biosphere, atmosphere, hydrosphere, and lithosphere, and how we are central components in these four spheres. This flexible, unbiased approach highlights:1. how matter cycles over time through Earth's systems2. the importance of the input-throughput-output processes that describe the global environment3. how human activities and consumption modify Earth's systems4. and the scientific, economic, and policy solutions to environmental problems
