Genetically Modified Organisms
Transcript of Genetically Modified Organisms
-Paul Berg Methods http://www.monsanto.com/whoweare/Pages/default.aspx What's the difference? In our world today...where do we find GMOs? Other GM crops GM Animals -Case Study on Rats
-Case Study on Monarch Butterflies
-The decrease in monarch butterflies is linked to an increase in GM crop usage
-Case Study on Glowing Cats
-GM cats resistant to FIV can help advance research with human HIV.
-Main Researcher: Eric Poeschla The Impact Environmental Impact
-dramatic alteration of ecosystems-example: the effect of Bt corn on caddisflies
-allergies: new proteins
-toxicity: increased toxicity due to gene damage
-gene flow and biodiversity: superweeds, decreased biodiversity Impact on Humans Evolutionary Significance GMOs and Politics An ethical study of GMOs The Church’s position on GMOs -recombinant DNA technology
http://www.pbs.org/wgbh/harvest/engineer/transgen.html -The purpose of creating genetically modified organisms is to improve current crops and food producers.
-Some GMOs have opened up avenues for new research on diseases such as AIDS and genetic studies.
-Monsanto says that the purpose of “sustainable agriculture [is] to meet the needs of a growing population.” Insertion
gene gun / gene cannon
Recombinant DNA Technology -controlled -uncontrolled -Scientists modify tomatoes, maize, potatoes, soybeans, sugarcane, beets, papayas, rice, and canola
-What is organic?
-We are what we eat Scientists also modify other plants used in industry. -new proteins, new allergens
-world hunger -Farming Community:Productivity vs Cost Impact on Animals -Balance of ecosystems - Genes “Escaping” Into the Environment
- GM oilseed plant and the development of the mustard “superweed”
- Pests and Pest-Resistant Crops Benefits
Disadvantages What type of debate takes place over this controversial topic? How do GMOs affect politics in our world today? What role does ethics play in genetically modifying these organisms? How does the Catholic Church view the use of genetics to modify organisms? -1999: European Union-2000: Biosaftey Protocol-US GMO’s -Two sided argument
-Motivation behind big time companies -No real stance but signs of some support. -Selective breeding: choice of a specific organism -GMO’S: modifying any organism 7 genetically modified animals that glow in the dark 1.
