Although the idea of protecting a portion of the Everglades arose in 1905, a crystallized effort was formed in 1928 when Miami landscape designer Ernest F. Coe established the Everglades Tropical National Park Association. It had enough support to be declared a national park by Congress in 1934, but there was not enough money during the Great Depression to buy the proposed 2,000,000 acres (8,100 km2) for the park. It took another 13 years for it to be dedicated on December 6, 1947. [70] One month before the dedication of the park, the former editor of The Miami Herald and freelance writer Marjory Stoneman Douglas published her first book, The Everglades: River of Grass. After researching the region for five years, she described the history and ecology of the south of Florida in great detail, characterizing the Everglades as a river instead of a stagnant swamp.[71] Douglas later wrote, "My colleague Art Marshall said that with [the words "River of Grass"] I changed everybody's knowledge and educated the world as to what the Everglades meant".[72] The last chapter was titled "The Eleventh Hour" and warned that the Everglades were approaching death, although the course could be reversed.[73] Its first printing sold out a month after its release.[74]
