In the United States, forest conservation became popular in the late 19th and early 20th centuries. Forest conservation involves the upkeep of the natural resources within a forest that are beneficial to both humans and the ecosystem. Forest conservation acts to maintain, plan, and improve forested areas. Forests provide wildlife with a suitable habitat for living along with filtering groundwater and preventing runoff. ==History== Around the year 1900 in the United States, Gifford Pinchot lead a movement of conservation. Gifford Pinchot made conservation a popular word in its application to natural resources. Throughout the next two decades, forestry professions became widespread. Following World War I, forestry became a cooperation between private landowners, the states, and the federal government. On March 21, 1933, U.S. President Franklin D. Roosevelt sent a message to the United States Congress to strengthen the United States forest resources. In the following days, congress enacted the establishment of emergency conservation work. This project consisted of twenty five thousand men working on forest protection by planting trees, watershed restoration and erosion control. About 2.2 billion seedlings were planted which marked a start of conservation in the United States.〔(【引用サイトリンク】url=http://www.foresthistory.org/ASPNET/Publications/highlights/sec5.htm )〕 In 1935, the Natural Resources Committee was created to understand, plan and use natural resources. Following World War II, the first Smokey Bear symbol appeared on a poster to represent a fire prevention cooperation. The Smokey Bear icon soon became one of the best advertisement icons in the United States. When people started to realize that the resources were not unlimited within the forests, conservation efforts began to start.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Forest conservation in the United States」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
