Students have asked these similar questions
Students are tasked to make a position paper about an article whichtackles GMO. The aim of this paper is to know whether they consider GMO asnecessary, safe and good for the environment.
Guide Questions:1. Do we need GMO foods?2. Are genetically modified foods safe?3. Are genetically modified foods good or bad for the environment?
Examples of GMOs
Correctly classify examples of bacteria, plants, and animals that have been genetically modified.
Produce biofuels and other chemicals for use
in manufacturing
Genetically Modified Bacteria
Reduce the impact of pest species by either
deterring them or killing them
Modified to have increased nutritional value by
reducing their susceptibility to disease, increasing
their rate of growth, and improving the quality of
the meat/milk
Provide organs for humans for transplantation
Serve as models for studying human diseases
such as cystic fibrosis
Produce enzymes to enhance metabolic
pathways to aid in the breakdown of toxic
chemicals in the environment
Allow organisms to better face environmental
challenges such as drought, heat, and high
salt content in the water supplies
Reduce the number of pest species that are
vectors for diseases such as Zika and dengue
fever
Modified to produce antibodies, vaccines, and
enzymes that can be used in the treatment of
humans
Provide plant's…
What are the advantages and disadvantages of GMOs in human health? Where does GMO stand today? Are canned food genetically modified? Does heating destroy the GMOs in the food?

- How are we going to feed and clothe the rapidly rising human population worldwide? How are we going to stop famine and crop loss? These are some very important questions biologists are working on as the world changes and problems arise. One possible solution could be the increased use of technology to improve food crops. These crops often have foreign DNA inserted into them that produces a protein product, such as herbicide resistance, to protect the plant or increase yield. They are termed GMO's (Genetically Modified Organisms) and they are hotly debated in both science and the public sphere. In this discussion you will demonstrate an understanding of GMOs and reflect on the pros and cons of their development and use This week's discussion involves 1 part. In this discussion, pick a side, PRO or CON, and argue your case that GMO's are either going to save the world or destroy it. You may very well find that this issue is not as black and white as it is made out to be! Please remember…arrow_forwardGenetic engineering is a process causes the production of GMOs ( Genetically Modified Organisms) due to the ideas of biologists. The presence of the products contributes the division of the society in relation to GMOs effects. TASK: You serve as a genetic engineer, if you are given a chance what GMO would you like to produce? What to do: Give a name of your GMO Illustrate and/or describe your GMO List all the possible pros and consarrow_forwardIn October 2002, the government of the African nation of Zambia announced that it was refusing to distribute 15,000 tons of corn donated by the United States, enough corn to feed 2.5 million Zambians for three weeks. The government rejected the corn because it was likely to contain genetically modified kernels. The government made the decision after its scientific advisers concluded that the studies of the health risks posed by GM crops “are inconclusive.” Do you agree with Zambia’s decision to turn away the corn? Why or why not? In your answer, consider that at the time, Zambia was facing food shortages, and 35,000 Zambians were expected to starve to death over the next six months. How do the risks posed by GM crops compare to the risk of starvation?arrow_forward
- AquAdvantage salmon is a genetically modified (GM) Atlantic salmon developed by AquaBounty Technologies. The Food and Drug Administration (FDA) has approved the company's application to allow the entry of this GM salmon into the United States food supply late last year. The FDA announced that: "AquAdvantage salmon is as safe to eat as any non- genetically engineered (GE) Atlantic salmon, and also as nutritious." However, opponents of genetically modified food are claiming that the AquAdvantage salmons could pose a serious environmental risk to the marine ecosystem if the engineered fishes escape from the farms. These transgenic salmons would be a big threat to the wild salmons. Justify this statement.arrow_forwardThe following statements refer to genetically-modified (GM) organisms. Which of the following statements (A-D) are TRUE? Choose all that are TRUE, or choose "None of the other statements are true" a) GM insects have never been intentionally released into the wild b) None of the other statements are true c) GM organisms are banned in the U.S. d) GM crops have been proven to be less nutritious than organic crops, and have been shown to increase cancer risk in people who eat them e) Since the time that glyphosate-tolerant crops were introduced (mid-1990’s), no glyphosate-resistant weeds have emergedarrow_forwardA. Hank is going to talk about Gene Guns and Agrobacterium which I will discuss in a video lecture next week. B. How long does it take to develop and bring a GMO crop to market? C. What are some of the drawbacks to GE organisms? D.One of the interviewees is a woman in bright pink t-shirt and she is trying to describe drawbacks to GMOs. While not a cogent argument, I think there is an important point that she is trying to make. Do you know what she is trying to say?arrow_forward
- Much of the controversy over genetically engineered foods has centered on whether special labeling should be required on all products made from genetically modified crops. Some people have advocated labeling that identifies the product as having been made from genetically modified plants. Others have argued that food labeling should be required to identify only the ingredients, not the process by which they were produced. Choose a side in this issue and justify your stand.arrow_forwardGenetically modified organisms (GMOs) are used to create human growth hormone, insulin and clotting factor proteins that are used to treat dwarfism, diabetes and hemophilia respectively. Several crops such as corn and soybean have also been genetically modified in order to facilitate either the management or growth of these crops. Why do you think there is push back or opposition against the use of GM food crops but not in the use of products such as insulin, which is also created using GMOs?arrow_forwardWhat is your stand on GMO especially in agricultural products? Do you agree that all food products should be modified in this manner? Justify your stand. make it an essay typearrow_forward
- Okay, maybe GMOs have decent uses but it can't all be good. I've heard all of the following about GMOs. Which ones are realistic concerns? select all that applys a)Some GMO are patented and farmers must buy seeds every year rather than saving them from their crops. b)GMO's cause allergies at a greater rate than crops produced by cross-breeding. c)Inserted genes produce amino acids not found in nature. d)Inserted genes may escape into wild plants near farmed fields.arrow_forwardWhat is your stand on GMO especially in agricultural products? Do you agree that all food products should be modified in this manner? Justify your stand.arrow_forward1a.) Please take a position for-or-against genetically modified agricultural products. 1b.)
