Environmental issues are often quantitative--how much land, how many people, what amount of pollution. Computer programs are useful, but there is no substitute for being able to use a simple calculation to slice through to the crux of the problem. Having a grasp of how the factors interact and whether the results make sense allows one to explain and argue a point of view forcefully to diverse audiences.

With an engaging, down-to-earth style and practical problem-solving approach, Ecological Numeracy makes it easy to understand and master basic mathematical concepts and techniques that are applicable to life-cycle assessment, energy consumption, land use, pollution generation, and a broad range of other environmental issues. Robert Herendeen brings the numbers to life with dozens of fascinating, often entertaining examples and problems.

Requiring only a moderate quantitative background, Ecological Numeracy is a superb introduction for advanced undergraduate students in environmental science, planning, geography, and physical and natural sciences. It is also a valuable professional resource for environmental managers, regulators, and administrators.
