U.S. National Lakeshore
The United States has ten protected areas known as national seashores and three known as national lakeshores, which are public lands operated by the National Park Service (NPS), an agency of the Department of the Interior. National seashores and lakeshores are coastal areas federally designated by Congress as being of natural and recreational significance as a preserved area. All of the national lakeshores are on Lakes Michigan and Superior, and nine of the ten national seashores are on the Atlantic Ocean, including two on the Gulf of Mexico. Point Reyes is the only national seashore on the Pacific coast. While all of these protected sites have extensive beaches for recreation, they extend inland to include other natural resources like wetlands and marshes, forests, lakes and lagoons, and dunes. Many also feature historic lighthouses and estates. National seashores are located in ten states and national lakeshores are in two other states. Florida, North Carolina, and Michigan e ...

Fort Pickens Area - Gulf Islands National Seashore (27809207236)
A fortification is a military construction or building designed for the defense of territories in warfare, and is also used to establish rule in a region during peacetime. The term is derived from Latin ''fortis'' ("strong") and ''facere'' ("to make"). From very early history to modern times, defensive walls have often been necessary for cities to survive in an ever-changing world of invasion and conquest. Some settlements in the Indus Valley civilization were the first small cities to be fortified. In ancient Greece, large stone walls had been built in Mycenaean Greece, such as the ancient site of Mycenae (famous for the huge stone blocks of its 'cyclopean' walls). A Greek '' phrourion'' was a fortified collection of buildings used as a military garrison, and is the equivalent of the Roman castellum or English fortress. These constructions mainly served the purpose of a watch tower, to guard certain roads, passes, and borders. Though smaller than a real fortress, they ...

Michigan
Michigan () is a state in the Great Lakes region of the upper Midwestern United States. With a population of nearly 10.12 million and an area of nearly , Michigan is the 10th-largest state by population, the 11th-largest by area, and the largest by area east of the Mississippi River.''i.e.'', including water that is part of state territory. Georgia is the largest state by land area alone east of the Mississippi and Michigan the second-largest. Its capital is Lansing, and its largest city is Detroit. Metro Detroit is among the nation's most populous and largest metropolitan economies. Its name derives from a gallicized variant of the original Ojibwe word (), meaning "large water" or "large lake". Michigan consists of two peninsulas. The Lower Peninsula resembles the shape of a mitten, and comprises a majority of the state's land area. The Upper Peninsula (often called "the U.P.") is separated from the Lower Peninsula by the Straits of Mackinac, a channel that joins Lak ...

National Recreation Area
A national recreation area (NRA) is a protected area in the United States established by an Act of Congress to preserve enhanced recreational opportunities in places with significant natural and scenic resources. There are 40 NRAs, which emphasize a variety of activities for visitors, including hiking, camping, boating, fishing, swimming, biking, horseback riding, and wildlife viewing, in areas that include multiple-use management for both conservation and limited utilization of natural resources. They have diverse features and contexts, being established around reservoirs, in urban areas, and within forests. Due to their size, diversity of activities, and proximity to population centers, NRAs are among the most visited units of the National Park System, with six among the thirty most visited sites. The first NRA was Lake Mead National Recreation Area, which was created by a 1936 agreement between the United States Bureau of Reclamation (USBR), which had built Hoover Dam, and the ...

Cape Hatteras National Seashore
Cape Hatteras National Seashore is a United States national seashore which preserves the portion of the Outer Banks of North Carolina from Bodie Island to Ocracoke Island, stretching over , and is managed by the National Park Service. Included within this section of barrier islands along N.C. 12, but outside the national seashore boundaries, are Pea Island National Wildlife Refuge and several communities, such as Rodanthe, Buxton, and Ocracoke. Cape Hatteras is a combination of natural and cultural resources, and provides a wide variety of recreational opportunities. Once dubbed the "Graveyard of the Atlantic" for its treacherous currents, shoals, and storms, Cape Hatteras has a wealth of history relating to shipwrecks, lighthouses, and the US Lifesaving Service. The islands also provide a variety of habitats and are a valuable wintering area for migrating waterfowl. The park's fishing and surfing are considered the best on the East Coast.

Outer Banks
The Outer Banks (frequently abbreviated OBX) are a string of barrier islands and spits off the coast of North Carolina and southeastern Virginia, on the east coast of the United States. They line most of the North Carolina coastline, separating Currituck Sound, Albemarle Sound, and Pamlico Sound from the Atlantic Ocean. A major tourist destination, the Outer Banks are known for their wide expanse of open beachfront and the Cape Hatteras National Seashore. The seashore and surrounding ecosystem are important biodiversity zones, including beach grasses and shrubland that help maintain the form of the land. The Outer Banks were sites of early European settlement in the United States and remain important economic and cultural sites. Most notably the English Roanoke Colony vanished from Roanoke Island in 1587 and was the first location where an English person, Virginia Dare, was born in the Americas. The hundreds of shipwrecks along the Outer Banks have given the surrounding seas th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Depression
The Great Depression (19291939) was an economic shock that impacted most countries across the world. It was a period of economic depression that became evident after a major fall in stock prices in the United States. The economic contagion began around September and led to the Wall Street stock market crash of October 24 (Black Thursday). It was the longest, deepest, and most widespread depression of the 20th century. Between 1929 and 1932, worldwide gross domestic product (GDP) fell by an estimated 15%. By comparison, worldwide GDP fell by less than 1% from 2008 to 2009 during the Great Recession. Some economies started to recover by the mid-1930s. However, in many countries, the negative effects of the Great Depression lasted until the beginning of World War II. Devastating effects were seen in both rich and poor countries with falling personal income, prices, tax revenues, and profits. International trade fell by more than 50%, unemployment in the U.S. rose to 23% and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Natural Resources Defense Council
The Natural Resources Defense Council (NRDC) is a United States-based 501(c)(3) non-profit international environmental advocacy group, with its headquarters in New York City and offices in Washington D.C., San Francisco, Los Angeles, Chicago, Bozeman, and Beijing. Founded in 1970, as of 2019, the NRDC had over three million members, with online activities nationwide, and a staff of about 700 lawyers, scientists and other policy experts. History The NRDC was founded in 1970.Robert Gottlieb, ''Forcing the Spring: The Transformation of the American Environmental Movement'' (revised ed.: Island Press, 2005), pp. 193–94. Its establishment was partially an outgrowth of the ''Scenic Hudson Preservation Conference v. Federal Power Commission'', the Storm King case. The case centered on Con Ed's plan to build the world's largest hydroelectric facility at Storm King Mountain. The proposed facility would have pumped vast amounts of water from the Hudson River to a reservoir and released ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea Level Rise
Globally, sea levels are rising due to human-caused climate change. Between 1901 and 2018, the globally averaged sea level rose by , or 1–2 mm per year on average.IPCC, 2019Summary for Policymakers InIPCC Special Report on the Ocean and Cryosphere in a Changing Climate .-O. Pörtner, D.C. Roberts, V. Masson-Delmotte, P. Zhai, M. Tignor, E. Poloczanska, K. Mintenbeck, A. Alegría, M. Nicolai, A. Okem, J. Petzold, B. Rama, N.M. Weyer (eds.) Cambridge University Press, Cambridge, UK and New York, NY, USA. https://doi.org/10.1017/9781009157964.001. This rate is accelerating, with sea levels now rising by 3.7 mm per year. Climate scientists expect further acceleration during the 21st century. Climate change heats (and therefore expands) the ocean and melts land-based ice sheets and glaciers. Between 1993 and 2018, the thermal expansion of water contributed 42% to sea level rise; melting of temperate glaciers, 21%; Greenland, 15%; and Antarctica, 8%. Over the next 2 ...

Barrier Island
Barrier islands are coastal landforms and a type of Dune, dune system that are exceptionally flat or lumpy areas of sand that form by wave and tidal action parallel to the mainland coast. They usually occur in chains, consisting of anything from a few islands to more than a dozen. They are subject to change during storms and other action, but absorb energy and protect the coastlines and create areas of protected waters where wetlands may flourish. A barrier chain may extend uninterrupted for over a hundred kilometers, excepting the tidal inlets that separate the islands, the longest and widest being Padre Island of Texas, United States. Sometimes an important inlet may close permanently, transforming an island into a peninsula, thus creating a barrier peninsula, often including a beach, barrier beach. The length and width of barriers and overall morphology of barrier coasts are related to parameters including tidal range, wave energy, Sediment transport, sediment supply, Sea leve ...

Climate Change
In common usage, climate change describes global warming—the ongoing increase in global average temperature—and its effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to Earth's climate. The current rise in global average temperature is more rapid than previous changes, and is primarily caused by humans burning fossil fuels. Fossil fuel use, deforestation, and some agricultural and industrial practices increase greenhouse gases, notably carbon dioxide and methane. Greenhouse gases absorb some of the heat that the Earth radiates after it warms from sunlight. Larger amounts of these gases trap more heat in Earth's lower atmosphere, causing global warming. Due to climate change, deserts are expanding, while heat waves and wildfires are becoming more common. Increased warming in the Arctic has contributed to melting permafrost, glacial retreat and sea ice loss. Higher temperatures are also causing m ...
