Cycles of Life: Civilization and the Biosphere

I found this book (2 ed. Scientific American 2001) to be easily readable, and while the general thrust of the work may be about the greenhouse effect that is not the main topic. Rather, the book focuses on exploring the flows of major substances in the environment e.g; carbon, nitrogen, water and phosphorous. I've loaned this book and and it was greatly appreciated there too. Alas, it seems it can be difficult to go back and reference material; the index is a bit skimpy and the text arrangement works well for reading but may only allow you to find the general section of what you are looking for.

This book gives the reader the background to consider the "Greenhouse Effect" and all its ramifications in a serious way. Very good reading and very thought provoking.
