    The Everglades: Wetlands not Wastelands Marjory Stoneman Douglas Overcoming the Barriers of Public Unawareness and the Profit Motive in South Florida Manav Bansal Senior Division Historical Paper Paper Length: 2,496 Bansal 1 "Marjory was the first voice to really wake a lot of us up to what we were doing to our quality of life. She was not just a pioneer of the environmental movement, she was a prophet, calling out to us to save the environment for our children and our grandchildren."1 - Florida Governor Lawton Chiles, 1991-1998 ​ Introduction Marjory Stoneman Douglas was a vanguard in her ideas and approach to preserve the Florida Everglades. She not only convinced society that Florida’s wetlands were not wastelands, but also educated politicians that its value transcended profit. From the late 1800s, attempts were underway to drain large parts of the Everglades for economic gain.2 However, from the mid to late 20th century, Marjory Stoneman Douglas fought endlessly to bring widespread attention to the deteriorating Everglades and increase public awareness regarding its importance. To achieve this goal, Douglas broke societal, political, and economic barriers, all of which stemmed from the lack of familiarity with environmental conservation, apathy, and the near-sighted desire for immediate profit without consideration for the long-term impacts on Florida’s ecosystem. Using her voice as a catalyst for change, she fought to protect the Everglades from urban development and draining, two actions which would greatly impact the surrounding environment, wildlife, and ultimately help mitigate the effects of climate change. By educating the public and politicians, she served as a model for a new wave of environmental activism and she paved the way for the modern environmental movement.

  • How Should Florida's Water Supply Be Managed in Response to Growth?
    Avoiding a Water Crisis in Florida –How Should Florida’s Water Supply be Managed in Response to Growth? by Lynne Holt “The source of the water crisis is simple but exceedingly difficult to address, water resources are finite but the population that depends on those supplies is increasing inexorably.” Dennis Hjeresen, Los Alamos National Laboratory and the Green Chemistry Institute 1 Water remains essential for life. According to the United Nations, 1.1 billion people throughout the world have no access to safe drinking water. In the United States, this is certainly not the case. However, water conflicts have pitted Colorado, Arizona, and other western states against each other, particularly in periods of drought, and Florida is no exception. These conflicts not only occur between states, but also within them. We need only think of the recent recommendation in a 2003 report by the Florida Council of 100 calling for a feasibility analysis of a new statewide water distribution system. The recommendation proposed “developing a system that enables water distribution from water­rich to water­poor areas seems to make good environmental and economic sense.” 2 It garnered widespread opposition from North Floridians, thus setting the stage for potential, prolonged water conflicts within the state. Although Florida is renowned for its wetlands, its enormous population growth in the last half of the 20 th century has caused widespread degradation to thousands of square miles of these wetlands. 3 Floridians in 2005 may not be facing a statewide water crisis at present but they are certainly facing enormous challenges. They cannot afford to be complacent.

  • The Biogeography and Ecology of Euphyes Dukesi (Hesperiidae) in Florida
    Journal of the Lepidopterists' SOciety 49(1), 1995, 6-23 THE BIOGEOGRAPHY AND ECOLOGY OF EUPHYES DUKESI (HESPERIIDAE) IN FLORIDA JOHN V. CALHOUNl 1731 San Mateo Drive, Dunedin, Florida 34698, USA ABSTRACT. A distinctive endemic phenotype of Euphyes dukesi (Lindsey) was first discovered in Florida in 1971. The endemic nature of Floridian populations was only recently recognized, and the populations currently remain undescribed. Pleistocene glacial events probably contributed to the isolation of these populations from populations on the North American mainland. The species has been found in at least five types of forested wetlands in Florida. The primary hostplant is Rhynchospora inundata (Oakes) Fern (Cyperaceae), but Rhynchospora miliacea (Lam.) A. Gray (Cyperaceae) and a species of Carex (Cyperaceae) also are utilized. Euphyes dukesi is bivoltine in Florida, with adults active primarily during May-June and September-October. Adults frequent sunlit patches of hostplants within swamps and visit a variety of nectar sources. The alteration and destruction of forested wetlands threaten populations of this species. Euphyes dukesi has a limited distribution and is considered rare in Florida. Additional key words: endemic, swamps, hostplants, energy resources, behavior. Since its description, Duke's skipper, Euphyes dukesi (Lindsey), has remained an enigmatic and poorly understood North American mem­ ber of the genus Euphyes. This species generally is considered rare and known from only a few widely separated localities (e.g., MacNeill 1975, Pyle 1981, Opler & Krizek 1984). In Michigan, E. dukesi is a state­ listed threatened species (Haack 1992). Owing to this perceived rarity, a number of distributional and ecological discoveries have been doc­ umented in detail (Pliske 1957, Mather 1963,1966, Price & Shull 1969, Irwin 1969, 1972, Covell et al.
