Young Brunette Girl Outside In The Wild Nature

By the 1920s, travel across North America by train to experience the "wilderness" (often viewing it only through windows) had become wildly popular. This led to the commercialization of some of Canada's National Parks with the building of great hotels such as the Banff Springs Hotel and Chateau Lake Louise.
Conservation vs. preservation
Two opposing factions had emerged within the environmental movement by the early 20th century: the conservationists and the preservationists. The conservationists (such as Gifford Pinchot) focused on the proper use of nature, whereas the preservationists sought the protection of nature from use. Put another way, conservation sought to regulate human use while preservation sought to eliminate human impact altogether.
