GMOs
What is a GMO?
A GMO, or genetically modified organism, is a virus, bacterium, or more complex life-form in which the DNA has been altered for a particular purpose. Some of these purposes include: research into the nature of genes and biological processes, manufacturing animal proteins, correcting genetic defects, and making improvements to animals and plants (Natural Environment Research Council). Making improvements to animals and plants is a major motivation to produce GMOs. With a world population on its way to 9 plus billion by the year 2050, a viable option for sustenance production is needed. With this ever-growing world population there is a need for somehow controlling the amount of people born. China is one country which has dealt with their overcrowding problem, but it seems that many of the other countries of the world are not doing much if anything to control their own populations. Because of this lack of action in controlling the world population, the need is shifted to how we will provide for all those people. GMOs are a way in which we as a world population can better provide for ourselves so that everyone will have enough provisions to survive.
How is a GMO created?
GMOs have been created naturally for millions of years. Agrobacterium tumefaciens is one example of a natural genetic engineer because it is able to alter another organism’s DNA to benefit itself. This species of soil-dwelling bacteria infects plant cells with a piece of its own DNA, and when it is integrated with the plant’s chromosome, it uses the plant’s own cells to proliferate the population of the bacteria. The way in which the bacterium does this is through the use of its bacterial chromosome and a plasmid, which is ...

This report aims to make light of certain elements of documentary making that are perhaps more susceptible to influence on the director’s part, and once again explore the effect of these decisions on the audience’s reaction to the information presented.
cut back on the problems in the Bay. Scientists have given an unthinkable amount of attention to the Bay of the past several years and researchers from countless numbers of agencies and institutions have dove deep into the issues and studying every nook and cranny to create answers to every politicians’ questions. The biggest concern with the Bay, and the most concentrated ...
One of the Bays biggest resources is its oysters. Oysters are filter feeders which mean they feed on agley and clean the water. The oysters feed on agley and other pollutants in the bay turning them into food, then they condense the food down to nutrients and sometimes developed pearls. Filtering the water helps the oysters to grow, and also helps clean the Chesapeake Bay. One oyster can filter 50 gallons of water a day, Oysters used to be able to filter the Bay in about a week. However, these creatures are now scarce in the bay. The Chesapeake Bays Oyster (crassostrea virginica) Population has declined severely because of over harvesting, agricultural runoff, and disease. Now the Chesapeake Bay is becoming polluted without the oysters and the water is not nearly as clean as it once was. The Chesapeake Bay was the first estuary in the nation to be targeted for restoration as an integrated watershed and ecosystem. (Chesapeake Bay Program n/d). This report will show the cause and effect of the Chesapeake Bay's Oyster decline on the Bay.
The Maryland Blue Crab is an essential part of the Chesapeake Bay; from the food chain of the creatures in the water, to the business side of the thriving demand for the crab during the hot summer months, but there is no denying the fact that the crab is just as important alive as it is when it is being harvested by local fisherman. By becoming more informed of the impact the crab has on Maryland’s bay and on the people who live around it, people can take bigger steps in making sure the crab will always be around for decades to come.
The Chesapeake Bay is the nation’s largest estuary with six major tributaries, the James, the Potomac, the Susquehanna, the Patuxent, the York, and the Rappahannock Rivers, feeding into the bay from various locations in Maryland, Virginia, Pennsylvania, and the District of Columbia (Chemical Contaminants in the Chesapeake Bay – Workshop Discussion 1). These areas depend on the Bay as both an environmental and an economic resource. Throughout the last 15 years the Chesapeake Bay has suffered from elevated levels of pollution. Nitrogen and phosphorous from wastewater treatment plants, farmland, air pollution, and development all lead to reduced water clarity and lowered oxygen levels, which harm fish, crabs, oysters and underwater grasses (Key Commission Issues 1). There are other types of pollution in the bay such as toxic chemicals, but because nutrient pollution is the most significant and most widespread in the Bay its effects are the most harmful to fisheries. Nitrogen and phosphorous fuel algal blooms which cloud the water and block sunlight from reaching underwater grass beds that provide food and habitat for waterfowl, juvenile fish, blue crabs, and other species (Blankenship 11-12). Algae plays a vital role in the food chain by providing food for small fish and oysters. However, when there is an overabundance of algae it dies, sinks to the bottom of the Bay, and decomposes in such a manner that depletes the oxygen levels of the Bay (11). The reduced oxygen levels in the Bay reduce the carrying capacity of the environment and these “dead areas” sometimes kill off species that can not migrate to other areas of the Bay, such as oysters (11). Increased abundance of algal blooms also led to the overabundance of harmful and toxic algae species and microbes such as the microbe Pfiesteria, which was responsible in 1997 for eating fish alive and making dozens of people sick (12). The heightened awareness of diseases that can be contracted through consumption of contaminated fish also has an economic impact. Therefore, the excess levels of nitrogen and phosphorous have fueled an overabundance of algal blooms, which has reduced water clarity and lowered oxygen levels, affecting many species within the bay and ultimately the industries that rely on these species.
First the causes of the dead zone will be introduced. Large contributors of excessive nutrients will be discussed. There is not one source to blame the Chesapeake Bay dead zone is a large problem with many variables that effect each other. Next the pressure that is put on the bay and its organisms will be discussed. A picture of what you might find out in the dead zone will be painted. The reality of the rapidly declining organism populations will be understood. Third, the possible solutions will be explained. Since this is a multiple variable problem there are many potential solutions that may or may not work. Last the lack of action will be observed. There are many solutions that could bring the bay back to life but the cost and lack of effort fr...
GMO stands for a ‘genetically modified organism’. A GMO is artificially developed by scientists to produce specific results such as sustain life through a drought or produce a greater quantity of fruit per plant (Monsanto Corporation:1999). This practice began centuries ago when plants and animals were selectively bred and microorganisms were us...
The Chesapeake Bay is a large bay that stretches from Maryland to Virginia, fed by many rivers and streams that run from as far north as New York to Virginia and West Virginia.5 It is home to a plethora of plants and fish species, many of which the people of the area fish for food and supplies. The pollution present in the Chesapeake Bay is affecting the livelihood of both the fishermen and the fish – the less the fishermen haul due to the death of the species they catch, the less they get paid – and as consumers of these fish, we are consuming the toxins as well.

Excessive nutrients from agriculture, development, and industry are harming the Chesapeake Bay. These excessive nutrients harm the habitat for many of the bays species. On top of the habitat being depleated, overfishing and diseases are also hurting the bays species. Nutrient loads can be reduced with the help of lawmakers to put a cap on the emissions allowed in the environment. If this is done the dead zone will start to recede, but the time and money need to be spent in order to save the bay.
... the residual effects of pollution left behind by both mining in the Chesapeake Bay area around rivers, such as the Susquehanna River in Pennsylvania, that feed into the Chesapeake Bay. Lutz also had quoted John Dawes, now the executive director of the Foundation for Pennsylvania Watersheds, on the damage done to streams and to the aquatic life in the streams. Dawes told Lutz "'we're looking at 4,600 miles of dead streams in Pennsylvania'" in reference to the vitality in polluted regions. This can occur in several ways but the two generally accepted causes are the toxicity levels in the water are too high to support life and the contaminated water is slowly killing off members of the food chains for the aquatic life. In either theory, the death of fish and their food chain caused by AMD is impacting the billion dollar fishing industry that calls Chesapeake Bay home.
The Chesapeake Bay has faced an excessive amount of pollution over the past century. The water in the bay has become so highly polluted that It is capable of causing harm to humans coming in direct contact with the water. Although algae serves a vital role in the bay’s ecosystem, it also creates a problem that is causing a large amount of the problem.
The Chesapeake Bay is a very large estuary that holds more than eighteen trillion gallons of water (“The Bay Watershed”). This large estuary is part of six of the different states of Maryland, Delaware, New York, Pennsylvania, Virginia, and West Virginia (“Chesapeake Bay Program”). Some characteristics of the bay are salinity, temperature, and circulation. The bay watershed is home to seventeen million people and gains more people each year, so it is no wonder why there are pollution problems (“Chesapeake Bay Program”). The Chesapeake Bay is the largest estuary in the United States and is diverse with life. Though the bay is filled with life, it faces many problems caused by humans.
The ideation of objectivity remains a highly debatable subject among philosophical elites. Some philosophers may argue that human’s understanding of objectivity is subject to the scope of understanding of the term and exposure (Livingstone & Plantinga 10). When the term objectivity is entwined with realism, it yields a complex ideation that remains highly debatable and less agreeable among erudite authors (Livingstone & Plantinga 23). However, to understand and appreciate the concept of realism and objectivity in film, it becomes critical to adopt a definite definition. First, the term reality in film is used to describe concepts that are visible in nature as experienced on a daily life by one or more individuals (Livingstone & Plantinga 24). The term objectivity in this case is used to define a set of ideations or perspectives that are incorporated in the film (Livingstone & Plantinga 24). Documentaries are used to create a form of reality, an experience or ideation of the person or group of person experiencing an event or phenomenon. The argument in this analysis is that it is impossible for documentary films to objectively capture reality.
