Environmental Science: Principles and Practices provides the scientific principles, concepts, applications, and methodologies required to understand the interrelationships of the natural world, identify and analyze environmental problems both natural and manmade, evaluate the relative risks associated with these problems, and examine alternative solutions (such as renewable energy sources) for resolving and even preventing them. Frank R. Spellman and Melissa Stoudt introduce the science of the environmental mediums of air, water, soil, and biota to undergraduate students.
Interdisciplinary by nature, environmental science embraces a wide array of topics. Environmental Science: Principles and Practices brings these topics together under several major themes, including

How energy conversions underlie all ecological processes

How the earth's environment functions as an integrated system

How human activities alter natural systems

How the role of culture, social, and economic factors is vital to the development of solutions

How human survival depends on practical ideas of stewardship and sustainability

Environmental Science: Principles and Practices is an ideal resource for students of science in the classroom and at home, in the library and the lab.
