This is a very interesting environmental history book that illustrates the relationship of energy, geography, materials and human/nonhuman action on the land. Relevant as the context to longer-term assessments of design outcomes, Lifecycle and Life Cycle Assessment, the assessment of the productivity or natural and artificial systems, etc.
