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 ...

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 ...
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.
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...
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.
The tidal salt marshes make vital contributions to the ecosystem in Jamaica Bay. The marshes help spawning processes and are primary nursery for species important to both recreational and commercial uses, providing protection from storm surges, and also removing pollutants and other toxic substances, which as a result, acts as a natural filter, improving the water quality in the bay. Salt marshes are low lying, grasslands that periodically become overwhelmed and drained by high tides. The fish and shellfish nurseries and are also a feeding ground for various species of wildlife in the ecosystem. They support a variety of invertebrates such as mussels, shrimp, oysters and horseshoe crabs that are key elements of the estuarine ecosystem. However, throughout the past few decades, the salt marshes at Jamaica Bay has significantly declined which created a tremendous negative impact on the general public in addition to the deterioration on the living habitats in the area. Many factors contribute to the decline such as sediment depletion, neighboring developments, increased tidal ranges, and especially nitrogen loading from untreated sewage. Although the damages done were unintentional, much of it was occurred due to negligence. As awareness has increased, restoration efforts have escalated as well as various groups respond well to mitigate the losses.
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.

One of the major problems affecting, not only oceans around the world, but also many local bodies of water right now is the problem of ocean acidification. You may have heard of ocean acidification, which you may have just disregarded as a problem that affects the large oceans as a whole. However, this acidification also affects the Chesapeake Bay itself. I have come to realize that the acidification of the Chesapeake is a major problem that will affect the diverse ecosystem that all the wildlife is located in, but also the many businesses locally and throughout the state that depend on the health of the ocean and the wildlife located in the
The Chesapeake Bay is the largest estuary in the United States. The bay holds eighteen hundred trillion gallons of water and stretches over 200 miles in length between its most northern point, the Susquehanna River to the Bay’s most southern tip, the Atlantic Ocean. Home to more than seventeen million people, the Chesapeake Bay is the primary water source for over 150 rivers and streams. Because of the vast amount of rivers and streams the bay feeds, this watershed impacts the lives of citizens on the eastern shore spanning a total of six U.S. states. The importance of the Chesapeake Bay is incredible; two of the United States’ five major North Atlantic ports – Baltimore and Hampton Roads – are on the Bay. (Chesapeake Bay Program, n/d). The highly productive ecosystem of the Chesapeake Bay provides food and shelter for a wide variety of plant and animal life in and surrounding the Bay. The critical natural resources the bay provides stimulates economic growth and has for centuries.
The Chesapeake Bay Program is doing many things to help with prevention of water quality. Extreme amounts of nutrients and sedimentation are entering the water and causing major pollution issues (Chesapeake Bay Program). One of the things they have been focusing on is erosion prevention. “In 2003, Bay Program partners agreed to cap sediment loads coming from watershed sources so that no more than 4.15 million tons of sediment are delivered to the Bay per year by 2010” (Chesapeake Bay Program). According to the Chesapeake Bay Program, “As of 2006, 62 percent of the sediment reduction goal had been achieved” (Chesapeake Bay Program). Another thing they are working on is improving the quality of wastewater treatment. Many wastewater treatment facilities throughout the Chesapeake Bay region are being upgraded with new technology to reduce the amount of nutrients that are being put into the bay (Chesapeake Bay Program).
...s for today’s leaders would begin with strong oral and written communication skills; the most effective way a leader communicates with the employees is by e-mail, since employees check their e-mail often they can communicate with them quickly but the employees also feel that the leaders are directly addressing them which can be motivating.
Oscar Wild once said, “The truth is rarely pure and never simple” and he is right. But no matter what the outcome is, or how complex the truth is, we will always strive for the truth. The concept of truth is no stranger to film documentaries, and one filmmaker that certainty was aware of that was Dziga Vertov. During the 1920’s Vertov created a newsreel series to promote the concept of ‘Kinopravda” which translated to English mean “Film truth.” Unfortunately, Vertov was ahead of his time, and this concept disappeared along the filmmakers’ path. It wasn’t until the 1960’s that other filmmakers around the world once again recognized the importance of the truth. Two movements with the purpose of revealing the truth of life, emerge in different parts of the world, Direct Cinema in North America and Cinema Vérité in France. Although, both had the same purpose, their approaches towards getting the truth make them completely different. Cinema Vérité’s approach gave the filmmakers a chance to manipulate and distort reality by participating and observing at the same time, while Direct Cinemas approach was strictly observational, and there is no better way to find out the truth than observing without interfering.
Listen as a leader taps into a range of understanding, ideas, and cooperative sentiments that failing to listen to leads to poor understanding or interpretation of orders and incorrect evaluations what you may hear; addressing these issues now allows for recognition and adapting personal attitudes to be more effective leaders (Simmons, 2011).
After the passing of a significant person the individuals who were close to the person generally take time to go through a grieving process in order to show respect for the dearly departed. The speaker in Browning’s poem should be doing the same, as the loss of a spouse is usually a traumatic experience. While he gives the façade of a loving and caring husband his attitude begs to differ, much like when the speaker says, “Oh, sir, she smiled, no doubt,/ Whene’er I passed her; but who passed without/ Much the same smile?” (43-45). The speaker seems to be grieving by remembering his Duchess’s wonderful smile but the smug tone that he speaks with quickly discredits his attempt at endearment. Instead of going through the normal stages of grief and remembering her fondly, his thoughts rapidly turn to bitterness because he felt that she gave the very same smile that should hav...
Genetically modified organisms can be plants or animals that have been genetically altered to produce or express a desired characteristic or trait. By genetically altering organisms such as crops, we can eliminate the use of pesticides by making the crops resistant to insects. We can also produce crops that are resistant to floods and droughts. Furthermore, with the use of molecular genetics, we are able to produce foods that are rich in nutrients and supplements. People in developing countries may not be fortunate enough to have a full course meal that contains nutrients from all four basic food groups. However, GMOs can with a little modification provide all the amino acids, vitamins, and minerals included in a good diet by simply consuming a genetically modified staple crop such as rice. In addition, by producing crops that are resistant to harsh environmental conditions as well as pests, we would see a rapid increase in the production of food thereby reducing and or!
