In the Florida Everglades ecosystem, Phosphorous is the main nutrient that the South Florida Water Management District is attempting to control. Phosphorous is the same nutrient that is a contributing factor to the algae problem in Lake Erie. In South Florida, the main source of drinking water stems from underground aquifers made of porous limestone, that is refilled via the everglades(NPS,2016). In our region, the main source for drinking water for cities, stems from Lake Erie. Thus,…

Egypt receives less than 80 mm of rainfall a year, and only 6 percent of the country is arable and agricultural land, with the rest being a desert. This leads to excessive watering and the use of wasteful irrigation techniques such as flood irrigation an outdated method of irrigation where gallons of water are pumped over the crops. Desertification is a land degradation problem of major importance in the arid regions of the world. Deterioration in soil and plant cover have adversely affected…

This research proposal seeks to test the hypothesis that pesticide run-off from agriculture, even in small amounts, can have a devastating impact on the aquatic ecosystem, in particular that of Daphnia.  For years, pesticides have been known to have devastating impact on the ecosystems surrounding the agricultural centers they are used in. On a regular basis, run-off from farms that utilize both fertilizers and pesticides can seep into the watershed and slowly trickle into bodies of water…

What is in your stream is very important to know. What runs through your streams will eventually run into creeks and then those creeks will run into the lake. In our case we will be testing Cole Camp Creek which runs into the Lake of the Ozarks. So, whatever pollutants that could be in the creek will eventually end up in Lake of the Ozarks. This paper will be telling what those stream pollutants can do to water systems. Nitrates Nitrate is essential for all living things because it is a…

local streams, rivers, and waterways by curbing runoff thereby reducing the level of runoff that reach the river, according to the website potomac.org*. This law made is possible for Maryland to collect a fee, based on the amount of paved or hardened surfaces on a property that collects pollution, from the community which they then used to fund local waterway clean-up efforts. (Potomac.org) These efforts have led to reduced pollution in the…

hat is a chemical spill? A chemical spill is an uncontrolled, accidental release of a chemical into the environment. What is remediation of chemical spills? The removal of unwanted, hazardous contaminants from an area. There are many methods by which this can be accomplished. Sodium Hydroxide can be fatal to aquatic animals. It is responsible for more than half a million fish in British Columbia in 2005. Phosgene can be released as a gas from household paint removers when exposed to heat. If…

2.1 Land Surface Temperature (LST) Land Surface Temperature is the radiative skin temperature of the land surface of land surface processes from local through global scales or it can be defined as an average temperature of features of the exact surface of the Earth calculated from measured radiance. It is a fundamental property of the Earth’s surface that can be determined remotely. Most of the papers uses the term land surface temperature and air temperature interchangeably, however these two…

Failure of Our Water System: “Fouling Our Own Nests” Analysis Robert Glennon’s “Fouling Our Own Nests” addresses the gravity of our nation’s current situation regarding water. Glennon’s work thoroughly examines “water pollution [as] an acute national problem” and supports this statement with two main sub-claims: water pollution as an origin of immense risk to human health and water pollution as the compromising source of future water supply. Although the two sub-claims are addressed in distinct…

the author finds that the increase in globalization has led to the need for a global public sphere. However, the author discusses concerns with new forms of public spheres being mediated through advertisers. Thus, while one can deduce that the surface web and many forms of traditional media do not follow Habermas’ requirement of a public sphere being free from the economic markets (like advertising), the article will benefit my argument by showing that the Deep Web presents an unmediated…
