Conservation Movement: Conservation Chronology 1847-1871

US Patent Agency Director Thomas Ewbank quoted an observation of the impact of deforestation by Alexander von Humboldt and others and warned in the 2nd volume report of the 1849 patent director (House of Representatives) enforcement File number 20) "Before our population reaches 50 million people, waste valuable timber in the US, not to mention firewood, then stupidity and myopia in this era are subject to some degree of accusations and condemnation "In the same document, Ewbank warns every year." Every year, a large number of bisons are killed, the constant war against them threatens their constant extinction, and then it will not cause great regret It will not. "In particular, considering their strength and familiarity, the ability to be domesticated, and the ability to be bound ..." Do not say that America's most expensive ruminant animals have been extinct. An article on long-term damage caused by deforestation was published in the report of the Patent Agriculture Committee from the 10th to the 1960s.

Let 's learn more about the history of American conservation, looking at the chronology of selected events in the development of the American protection movement from 1847 to 1920. It was shown in evolution series of protection movement from 1850 to 1920. The series also includes a short trip to Thoreau

Early conservation campaigns included fishery and wildlife management, water, soil conservation, and sustainable forests. The modern conservation movement has expanded from the focus of the initial movement to the protection of the wilderness area, including the use of sustainable natural resources and biodiversity conservation. Some say that the protection movement is part of a broader and widespread environmental movement, others think that ideology and practice are different. Mainly in the United States, protection is thought to be different from environmental protection as protection is aimed at protecting natural resources. Outside the United States, the term protection includes wider environmentalism.

During the protective movement of the progressive era (1890s - 1920s), protection first became a national problem. Early national protection movement shifted focus to scientific management, which helped large enterprises and controls begin to transition from local governments to state and federal governments. (Jade) Some authors believe that the impact of protective movement is increasing, and athletes, hunters and fishermen will be affected. In the 1870 's, American athletes, forests and streams, fields and streams, and other athletes' magazines were thought to have led to the development of the protection movement. (Reiger) This protection movement also encourages the establishment of state parks, national parks, forests, wildlife sanctuary, and national monuments designed to protect the remarkable natural landscape. The main concern of the protection group is that its origins are in general expansion.
