Environmental Change 
The Evolving Ecosphere

Environmental Change explores the nature, causes, rates and directions of environmental change throughout earth history. Huggett introduces the interdependent parts of the natural environment — cosmic, ecological, geological — and the dynamic nature of the environmental system. Integrating a wealth of examples and illustrations from around the world, the book examines evidence and causes of change in life, climate (air and water), soils, sediments and landforms, and the impacts of human-environment interaction.
