The Earth as Modified by Human Action

By George Perkins Marsh

Book Overview

The object of the present volume is: to indicate the character and, approximately, the extent of the changes produced by human action in the physical conditions of the globe we inhabit; to point out the dangers of imprudence and the necessity of caution in all operations which, on a large scale, interfere with the spontaneous arrangements of the organic or the inorganic world; to suggest the possibility and the importance of the restoration of disturbed harmonies and the material improvement of waste and exhausted regions; and, incidentally, to illustrate the doctrine that man is, in both kind and degree, a power of a higher order than any of the other forms of animated life, which, like him, are nourished at the table of bounteous nature. In the rudest stages of life, man depends upon spontaneous animal and vegetable growth for food and clothing, and his consumption of such products consequently diminishes the numerical abundance of the species which serve his uses. At more advanced periods, he protects and propagates certain esculent vegetables and certain fowls and quadrupeds, and, at the same time, wars upon rival organisms which prey upon these objects of his care or obstruct the increase of their numbers. Hence the action of man upon the organic world tends to derange its original balances, and while it reduces the numbers of some species, or even extirpates them altogether, it multiplies other forms of animal and vegetable life.

Human Agency and Landscape Alteration

Although a dipolmat by profession, Marsh was the first environmentalist to describe the interrelationships between environment and culture. Today he is best remembered for his key work, "Man and Nature." In that classic work, he was the first to suggest that human agency constituted a major element in landscape change. The accepted view held by prominent geographers and geologists of his day was that the physical aspects of the earth were entirely the result of natural process and phenomena, including topography, geological materials, erosion, weathering, climate, etc. Before Marsh, no one had ever thought to study the earth in ways that it was changed by human actions. After his pioneering work, no serious environmentalist or geoscientist can afford to overlook the consequences of those actions on the land. A well-read copy of this book belongs in the personal library of every earth scientist, environmentalist, and conservationist. Marsh's book is a MUST READ for anyone concerned about what people are doing to the earth.

A Very Modern Environmentalist, Writing in 1864!!!

In 1864, George P. Marsh explained how civilizations create ecological disasters. His central thesis is that cutting down forests desrupts otherwise stable hydrological cycles, thereby causing erosion and degrading plant and animal habitats. The book is vaste, creative and detailed. An American from Vermont, Marsh also lived in Turkey and Italy, and pursued numerous careers, as diplomat, lawyer, businessman, and professor. His intense love of language and history merged with direct obersvations here and abroad to generate a remarkable breadth of knowlegde and a strong desire to communicate. In Man and Nature, Marsh is not only inspired, he is also happy to digress, particularly in the abundant footnotes.
