Eutrophication

Threats and the future of Shellfishing Cape Cod has changed dramatically over the years, and because of these changes, there are serious impediments happening to the shellfish aquaculture expansion (Brennessel, 2008). The most important threat that is occurring presently is water quality. Years of increasing population with concomitant residential development, unaccompanied by wastewater infrastructure has resulted in nitrogen pollution (Ashworth, n.d.). On the cape, around 85% of the…

segments: water quality, soil fertility, air quality, and greenhouse gas emissions. These first two segments, which are applicable to my research paper, offer extensive information about the impacts on soil, water, aquaculture, the process of eutrophication, leaching, and a variety of other topics that relate to my research. Likewise, the discuss the impacts on land animals, both wild and domesticated. Similar to one of the previously discussed resources, a major feature of this research article…

habitat such as accelerated plant growth, low dissolved oxygen, and death to certain fish (Detter, 2). Knowing the concentration of phosphate is a water quality issue because most digestive problems are results of high levels of phosphate as well as eutrophication, or the overgrowth of plants (Detter, 2). Knowing the concentration of phosphate in water can prevent reservoirs and other aquatic habitats from dying (Water Research Center). In the…

Running Head: CLIMATE CHANGE Global warming is catastrophic once no action is taken to counteract that as in the case of Alaska. Alaska State is the largest in the United States of America having 20% of the United States. This state also has a wide range of ecological and climatic conditions which include glaciers, tundra, rainforests, meadows, and boreal forest. The warming in Alaska has increased over the last 60 years more than twice of the warming in the United States as warming in…

Literature Review of Class Bivalves 1. Introduction Freshwater and marine bivalves Taxonomy, ecological value, economical value, current Issues, current threats 2. Taxonomy According to Treatise on Invertebrate Paleontology, the Bivalves class was divided into six subclasses which cover 13 orders. The first subclass, Palaeotaxodonta, have characteristics such as small body, taxodont, protobranch, infaunal and aragonitic shells. This subclass has only one order, Nuculoida. In the second…

increases the probability and severity of floods.” (Aillery et al.) Vital crop nutrients like nitrogen and phosphorus that are applied to fields each year in large volumes can runoff or leach into water sources. A major environmental concern is eutrophication of surface water, resulting in decreased oxygen levels and death of aquatic life. “As much as 15 percent of the nitrogen fertilizer applied to cropland in the Mississippi River Basin makes its way to the Gulf of Mexico.” (Aillery et al.) …

Agriculture covers thirty-eight percent of Earth’s land surface, but the land has continually been turned into cropland as the world’s population steadily increases (Brennan, Withgott pg. 225). Food is a necessity to human survival, however, agriculture, specifically industrial agriculture has caused multiple environmental impacts. Compared to the other land uses, agriculture causes the most harm to the planet due to the use of inorganic fertilizers, machinery, irrigation, pesticides,…

Introduction: Within this task we were required to determine the ecological state of the Reddam House wetland, which I presume is at a good standard. I decided to test the ecological status of the wetland by gathering samples from the wetland and testing it for various aspects in the water and the plants that are found within the area. Method: • Collected water in a sterilized bottle at Reddam House wetland as well as observed surrounding fauna and flora. • Took the water to Rand Water to have…

70% of the world’s fresh water is used for agriculture, mainly for irrigation. The water systems have also been contaminated by fertilizers and pesticides used for growing crops. This leads to eutrophication (massive growth of algae bloom) due to phosphorus and death of aquatic animals. Moreover, agriculture contributes directly to 12-16 % of global greenhouse gases, which leads to rise in global temperatures. Enteric fermentation in livestock (methane)…

Pollution is a term used to describe mostly particles that are harmful in the air. Many things can cause pollution weather they be human like riding the car instead of taking the bus or natural phenomena like the eruption of a volcano. Pollution can come in many forms; they can be in tiny solids ranging from a few microns to gases floating around in the atmosphere. A recent study shows that pollutants less than 10 microns in diameter are in correlation with people dying of lung and heart…
