The human-environment conditions in the Americas on the eve of the sixteenth-century European conquest have of late attracted growing interest in both academic and public circles. Focusing on Middle America, this book completes a trilogy which has made the most comprehensive survey ever achieved of pre-Colombian agriculture and culture throughout the continents. It addresses the question of what lands were permanently occupied; how they were used; and what the environmental and social implications of this use were. The answers to these questions are central to such wide-ranging themes as...

The Earth as Transformed by Human Action is the culmination of a mammoth undertaking involving the examination of the toll our continual strides forward, technical and social, take on our world. The purpose of such a study is to document the changes in the biosphere that have taken place over the last 300 years, to contrast global patterns of change to those appearing on a regional level, and to explain the major human forces that have driven these changes. The first section deals strictly with the major human forces of the past 300 years and the second is a detailed account of the...

Legumes have taken an important place as a commercial crop in Texas. Their soil-building qualities have long been recognized, and the production of legume seed became a growing business. In addition, considerable interest arose as to the possibility of breeding and selection of native legumes for the development of suitable types to occupy the thousands of miles of rangeland in the southwestern United States. While much experimental work went into the production of exotic cultivated crops such as clover, alfalfa, and vetch, when this book was published in 1959, practically nothing was...
