Environmentalism preached that nature was almost sacred, and that man was an intruder. It allowed for limited tourism (such as hiking), but opposed automobiles in national parks. It strenuously opposed timber cutting on most public lands, and vehemently denounced the dams that Roosevelt supported for water supplies, electricity and flood control. Especially controversial was the Hetch Hetchy Dam in Yosemite National Park, which was built in 1923. Despite the efforts of presidents [[Ronald Reagan]] and [[George W. Bush]] as well as the Sierra Club, the dam still stands, largely due to the lobbying of San Francisco democrats such as Nancy Pelosi. | Environmentalism preached that nature was almost sacred, and that man was an intruder.
