LA Wetlands
Wetlands of Louisiana are the water-saturated swamp and coastal regions of southern Louisiana. This may cease to exist (ibid).
The Environmental Protection Agency says that wetlands are "those areas that are inundated or saturated by surface or groundwater at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions (e.g. swamps, bogs, fens, marshes, and estuaries) ("Environmental Protection Agency")."
These areas make up just a very small percentage of the total land to be found in America, Southern Louisiana contains some 40-45% of the wetlands to be found in the lower United States. This is the case in Louisiana because the state represents the drainage gateway to the Gulf of Mexico from the Lower Mississippi Regional Watershed. The Lower Mississippi Regional Watershed acts to drain more than 24 million acres (97,000 km2) in 7 states from the southern part Illinois to the Gulf of Mexico (WN).
The east coastline of Louisiana is more susceptible to coastal erosion than the west coastline because a lot of the east coastline was created by the silt deposits from the Mississippi. The west coastline is made up of marsh. However, the marshes extend inland by only 30 miles at the most. The elevation begins to increase after that and the marshes then fade into prairies. As a result, rising sea levels (because of coastal erosion and

Wetlands have proven to have many functions in the environment as well as for the human population in its area. Louisiana's wetlands are of global ecological importance. Many Louisiana natives present living on the Gulf of Mexico will have to face horrible problems if the coastal erosion continues to grow at the pace it is going. The loss of Louisiana's coastal wetlands is a problem that will impact a wide range of individuals, from those that live in the metropolitan areas to those who far away as well as those living in smaller cities along the shore. The resources that this ecosystem supplies are then utilized nationwide. The U.S. is expected to lose billions of dollars from seafood, the oil, gas revenues and also commercial shipping if the Louisiana's coast recedes more (ibid).
Louisiana's wetlands are a home to plants, fish and other wild life that is exclusive to the area. Unfortunately, their habitat is shrinking steadily and about half of Louisiana's original wetlands have been lost over the last two hundred years. The state's disappearing wetlands have had a broad impact that ranges from the cultural to the economic. The commercial fishing industry in the state accounts for over $300 million of the…

One potential solution for farmers would be to switch to a subsurface drip irrigation system that could permanently cut farmers' water use by 25 to 50%. This would alleviate some of the need for conservation and free up more state water reserves for urban locations during times of regional drought. ("University of Arizona studies underground irrigation,"2005, U.S. Water News Online) Arizona farmers are resistant to drip irrigation, however, and prefer
Anthropological Analysis; The Water Resources of New York This paper is an illustration of the supply problems of water resources of long island, New York. It has 5 sources. The human being has certainly come a significantly long way in terms of exceptionally evolutionary development and advancement within all sectors and components constituting the geographical as well as intangible parameters of contemporary society. Though there have been various, monumentally significant outcomes and
The land could not resist to the saturation caused by the winds and the heavy rain and it had not been long before the aftermath materialized into swollen mountain streams. This later resulted into cascades of mud mixed with water running down the slopes in serious amounts. In spite of the fact that the island had several drains and catch basins which could be very effective in case of
Water Pollution Water is an important natural resource upon which all the living beings rely for their existence and growth. Nature has blessed the earth with uncountable water resources but usable quantity is limited. Hence, it is important to use water sparingly. The irony is, human activities result is high water pollution which further shortens the water supply for use. "In an age when man has forgotten his origins and is blind
Clean Water An Analysis of Worldwide Efforts to Bring About Clean Water Sustainability The concept of clean water for everyone is very normal in the United States. There is nothing foreign about this concept, and nothing out of the ordinary. In fact, it is a given that all should have clean water in this country and it is because all people do have clean water, and an abundance of it. Yet there
Although the Murray-Darling River covers only about 14% of Australia's irrigated land, 50% of Australia's sheep and 25% of Australia's cattle rely on this source. Also, 40% of the nation's rice crop and 80% of its canned fruit product relies on the Murray-Darling River Complex. In all, three-quarters of Australia's water comes from the Murray-Darling River (Hussainy, p. 205). Of course there are conflicts when so much is at stake.
