Book Description
Since humans first appeared on the earth, we've been cutting down trees for fuel and shelter. Indeed, the thinning, changing, and wholesale clearing of forests are among the most important ways humans have transformed the global environment. With the onset of industrialization and colonization the process has accelerated, as agriculture, metal smelting, trade, war, territorial expansion, and even cultural aversion to forests have all taken their toll. Michael Williams surveys ten thousand years of history to trace how, why, and when human-induced deforestation has shaped economies, societies, and landscapes around the world. Beginning with the return of the forests to Europe, North America, and the tropics after the Ice Ages, Williams traces the impact of human-set fires for gathering and hunting, land clearing for agriculture, and other activities from the Paleolithic through the classical world and the Middle Ages. He then continues the story from the 1500s to the early 1900s, focusing on forest clearing both within Europe and by European imperialists and industrialists abroad, in such places as the New World and India, China, Japan, and Latin America. Finally, he covers the present-day and alarming escalation of deforestation, with the ever-increasing human population placing a possibly unsupportable burden on the world's forests. Accessible and nonsensationalist, Deforesting the Earth provides the historical and geographical background we need for a deeper understanding of deforestation's tremendous impact on the environment and the people who inhabit it.

Book Description
At a meeting of dendrochronologists an American colleague described the effects of volcanic eruptions on annual ring formation in bristlecone pines. I knew very little about either volcanoes or American pines! At the same meeting European scientists spoke on the dendrochronological dating of lakeshore settlements and the effects of larch bud moth attack on trees in the Alps. It is possible that American participants were not in a position to fully appreciate these papers either. In other words, dendrochronology is an extremely interdisciplinary science; its facets range from modern statistics on wood anatomy to the history of art. It is difficult even for dendrochronol ogists to keep in touch with the whole spectrum, and even more difficult for the layman to obtain an overall view of the many methods and fields of application. In recent times specialisation has begun to hinder communication be tween the various sectors. Archaeologists, for instance, set up their own dendrochronological laboratories and construct independent chronologies to serve their particular interests. The scientific institutions which previously carried out such work are now turning more and more to strongly statistically or biologically-oriented questions. The full wealth of information contained in tree rings, however, will be revealed only when dendrochronologists make a concerted effort to relate the findings of the different fields. In spite of inevitable specialisation, it is necessary that the expert concern himself with the work of his colleagues.
