The Earth As Modified By Human Action

The Earth As Modified By Human Action is a book written by George P. Marsh, originally published in 1874. The book is an early work of environmental science and conservation, exploring the ways in which human activity has impacted the natural world. Marsh argues that human actions such as deforestation, agriculture, and industrialization have led to significant environmental degradation, including soil erosion, climate change, and the extinction of species. He also discusses the ways in which these changes have impacted human societies, including the spread of disease, famine, and social unrest. The book is considered a seminal work in the field of environmental science and has been influential in shaping modern conservation and sustainability efforts.There can be no doubt that moisture is given, out by trees and evaporated in extremely cold winter weather, and unless new fluid were supplied from the roots by the exercise of some vital function, the tree would be exhausted of its juices before winter was over. But this is not observed to be the fact, and, though the point is disputed, respectable authorities declare that ""wood felled in the depth of winter is the heaviest and fullest of sap.""This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
