Please direct any feedback to ASTE graduate student Olivia Horning at [email protected] START COURSE 1 Lesson 5: Bioethics Gavrilescu, M. (2010).

Give an example of a concern related to the following categories: ecologic, economic 3 Genetic Engineering in Bioethics Agriculture Lesson 1 Vaccine Producing Food Lesson 2 • Foods can be genetically engineered to contain vaccines, also Lesson 3 known as “edible vaccines”, which could be easier to deliver Lesson 4 vaccines to children. Lesson 5 • Do you think this is a good idea? Why or why not? Create a pros and cons list to share with the class. Lesson 6 Lesson 7 4 Genetic Engineering in Bioethics Agriculture Lesson 1 What is Bioethics? Lesson 2 • The origin of the term is in the article “Bioethics, the Science Lesson 3 of Survival” where Van Rensselaer Potter defines the term as: Lesson 4 • “A science of survival must be more than science alone, and I Lesson 5 therefore propose the term ‘bioethics’ in order to emphasize the two most important ingredients in achieving the new Lesson 6 wisdom that is so desperately needed: biological knowledge Lesson 7 and human values.” • Biology + ethics = bioethics 5 Genetic Engineering in Bioethics Agriculture Lesson 1 What is Bioethics? Lesson 2 Lesson 3 Lesson 4 Lesson 5 Lesson 6 Lesson 7 6 Genetic Engineering in Bioethics Agriculture Lesson 1 Safety and Ethics Lesson 2 • Because of the dangers associated with genetic engineering, Lesson 3 laboratory procedures such as researcher protection from Lesson 4 infection and keeping all microbes in the lab. Lesson 5 • Genetic crippling is when microbe strains used in experiments involving recombinant DNA are unable to survive outside the Lesson 6 lab, but dangerous experiments can be banned. Lesson 7 7 Genetic Engineering in Bioethics Agriculture Lesson 1 Safety and Ethics Lesson 2 • Should humans have the ability to create new organisms or Lesson 3 alter an existing organism’s genes? Lesson 4 • Is it unethical, or has it been done through artificial selection Lesson 5 for centuries? (Pearson Education, 2016) Lesson 6 Lesson 7 8 Genetic Engineering in Bioethics Agriculture Lesson 1 3 Spheres of Sustainability Lesson 2 • Draw the following Lesson 3 diagram and write in the definitions for each circle Lesson 4 part. Lesson 5 • Discuss as a class.

One appendage Lesson 3 rests in health, another in environment, and the third is planted firmly in the social, cultural and historical meanings of rural life. Medically-based Lesson 4 dietary advice may be grounded in a concern for human health, but it has Lesson 5 the potential for both cultural and environmental reverberations. Agricultural and food issues have a natural place in the bioethics Lesson 6 spectrum, even when bioethics is conceived narrowly in terms of human health. But a complete understanding of these issues will require insight Lesson 7 from all three legs of the agricultural ethics stool.” – Paul B. Thompson, Michigan State University 10 Genetic Engineering in Bioethics Agriculture Lesson 1 3 Legged Milking Stool Lesson 2 • Draw the following diagram Lesson 3 and write in the definition for each leg. Lesson 4 • Discuss as a class.

Lesson 4 • 457 million acres grown in 2016 around the world Lesson 5 • Grown in 28 countries, developing countries, >18millin Lesson 6 farmers • Global cultivated crop land = 9% Lesson 7 • 5 countries growing 90% of gmo crops in 2015, 91% in 2016: USA, Brazil, Argentina, India, Canada 12 http://time.com/3840073/gmo-food-charts/ 13 14 15 16 Genetic Engineering in Bioethics Agriculture Lesson 1 Benefits/Supporters Lesson 2 • Environmental, Health, Economic, world problem solving Lesson 3 Lesson 4 Lesson 5 Lesson 6 Lesson 7 17 Genetic Engineering in Bioethics Agriculture Lesson 1 Benefits/Supporters Lesson 2 • Supporters say the technology will be better for the environment Lesson 3 • Fewer chemicals are used with herbicide resistance compared to Lesson 4 conventional crops • Herbicide resistant crops, like roundup ready corn or soybeans Lesson 5 • Insect resistant crops, like bt corn and bt cotton Lesson 6 Lesson 7 18 Genetic Engineering in Bioethics Agriculture Lesson 1 Benefits/Supporters Lesson 2 • Supporters say there are health benefits Lesson 3 • Higher quality and nutritional value, shelf life longer, sugar beets with Lesson 4 lower calories, lower saturated fat oils, benefitting world’s poor, added vitamins and minerals, golden rice, mass producing substances like Lesson 5 pharmaceuticals Lesson 6 Lesson 7 19 Genetic Engineering in Bioethics Agriculture Lesson 1 Benefits/Supporters Lesson 2 • Supporters say farmers will benefit Lesson 3 • Avoiding losses, single broad-spectrum herbicide reducing land Lesson 4 degradation, losses reduced from sudden frosts, GM crop yields increasing 5 to 8 percent (corn, cotton, soybeans) Lesson 5 Lesson 6 Lesson 7 20 Genetic Engineering in Bioethics Agriculture Lesson 1 Benefits/Supporters Lesson 2 • Supporters say that GM Seeds will aid in feeding the growing world Lesson 3 population Lesson 4 Lesson 5 Lesson 6 Lesson 7 21 Genetic Engineering in Bioethics Agriculture Lesson 1 Concerns Lesson 2 • Ecological, health, genetic, contamination, patent, Lesson 3 geopolitical Lesson 4 Lesson 5 Lesson 6 Lesson 7 22 Genetic Engineering in Bioethics Agriculture Lesson 1 Concerns Lesson 2 • Opponents say that wildlife could be harmed by GM crops, pesticide Lesson 3 resistant ‘Superbugs’ and ‘Superweeds’ (Refugee area is now needed for Bt crops to slow resistant insect development. Bt is a soil bacterium that Lesson 4 organic growers spray on crops as a pesticide, and resistant insects would Lesson 5 nullify this practice. • Super weeds are herbicide resistant due to uncontrollable cross Lesson 6 pollination by wind, birds, insects. Lesson 7 • “Natural” species competition, creating a loss of diversity. • Non-target species includes harming birds, non pest insects, and animals. Specifically, transgenic Bt corn harming monarch butterfly, known through a Cornell University study. 23 Genetic Engineering in Bioethics Agriculture Lesson 1 Concerns Lesson 2 • Opponents say that GM foods could cause health problems Lesson 3 • Animal experiments include: the liver, heart, and brain being smaller, with Lesson 4 a reduced immune system, in rats fed potatoes with GMO protein. (reword). Antibiotic gut resistance found in mice were the trans-genes Lesson 5 were not degraded in digestion. • Allergies due to proteins, 90% of food allergies are due to proteins. For Lesson 6 example, though, the brazil nut protein in soybean was never on the Lesson 7 market. 24 Genetic Engineering in Bioethics Agriculture Lesson 1 Concerns Lesson 2 • Lack of control over location of insertion, which could disrupt other genes. Lesson 3 The role of the gene may be unknown, or have different functions based on the organism. For example, the genet in rats for sense of smell, in Lesson 4 Zebra finches for song learning, and humans for Parkinson’s disease are Lesson 5 the same gene. • Concerns with cross pollination and segregation. Because corn is the most Lesson 6 highly used biopharma crop, there are concerns with cross-pollination Lesson 7 with plants engineered to contain human antibodies, like contraceptive corn (epicyte gene) and herpes-fighting antibody (human gene). Proposing that there may be inadequate segregation of crops, such as crops for human vs. animal feed with the StarLink corn recall. 25 Genetic Engineering in Bioethics Agriculture Lesson 1 Concerns Lesson 2 • Starlink corn is a GMO product FDA approved for animal feed but not Lesson 3 human feed, and found in September of 2000 in human food. $1 billion was lost. Companies affected included Kraft, taco Bell, Mission, and Lesson 4 Kellog’s Lesson 5 Lesson 6 Lesson 7 26 Genetic Engineering in Bioethics Agriculture Lesson 1 Economics Lesson 2 • Opponents say small farmers will be affected negatively by GM crop Lesson 3 technology, making them dependent on big firms. Lesson 4 • Biotech crops could be too expensive in developing countries. • Increased reliance on monocultures, with 90 % of food being grown from Lesson 5 15 crops. Lesson 6 • Monoculture crops predisposition for disease and pests due to lack of diversity. Lesson 7 27 Genetic Engineering in Bioethics Agriculture Lesson 1 Economics Lesson 2 • Opponents also say that profit driven biotech companies are not Lesson 3 concerned with risk to nature or people. Lesson 4 • Money invested in research and development needs to be recuperated. • High volume crops are the focus, such as soybeans, corn and cotton, Lesson 5 rather than food crops to help those in poor countries.
