1. RTW: Wed. Feb. 5 th  What do you think malnutrition is?  Read the last paragraph on page 374.

2. GENETICALLY MODIFIED FOODS

3. Case Study! How can we prevent malnutrition? Hunger isn't just a stomach thing | World Vision

4. Golden Rice

5. What are genetically modified foods?  Also called genetically modified organisms (GMO).  Involves the insertion of DNA from one organism into another OR modification of an organism’s DNA in order to achieve a desired trait. http://youtu.be/eCPtDVnaQ1w

6. Examples of GMO’s Frost Resistant Strawberries Long Lasting Tomatoes

7. Examples of GMO’s

8. Bt corn – corn that contains a chemical normally found in a bacterium (Bacillus thuringiensis) that is toxic to insects but not to humans.

9. How is it done?  By Recombinant DNA technology 1. Restriction enzymes are used to “cut” DNA segments from one genome. 2. DNA ligases are used to “paste” them into another genome.

10. How are plants targeted?  A particle gun is used to shoot small bits of metal coated with the gene into the plant. 7

11. Potential Environmental Hazards Reduced effectiveness of pesticides as insects become resistant to engineered toxins. Loss of biodiversity Harm to other organisms Pollen from Bt corn was shown to cause high mortality rates in monarch butterfly larvae (9). BUT follow-up studies have shown that the exposure levels in the fields are negligible (10). 11

12. Potential Environmental Hazards Gene Transfer to non-target species  Herbicide resistant plants and weeds could cross breed and create “superweeds”  To address this one could:  Create sterile male plants that don’t produce pollen  Engineer the plants so that pollen doesn’t contain the foreign genes  Create buffer zones of non-GM crops around GM crops. The buffer crops would not be harvested.

13. Potential Human Health Risks Allergens  Genetic engineering could potential introduce or create allergens  For example, inserting genes from a nut into another plant could be dangerous for people who are allergic to nuts Unknown health risks  Biological processes involve a lot of INTERACTIONS  It is often difficult to identify every possible interaction.

14. Economic Hazards  Elimination of competition  GM seeds are patented  Suicide seeds  Plants with sterile seeds that are infertile are created  Farmers are forced to buy seeds every year  However, some companies have reduced costs or donated GM seeds to impoverished nations.

15. RTW: Thurs. Feb. 6  What can people do to be better informed about what is in the foods they eat?  Do you like bacon?bacon

16. Creating a balance  So are GM foods a good or bad thing?  It depend on each individual case.  Consumers, the government and scientists should be responsible for weighing the benefits against the costs. Improved Nutrition Resistance to disease Reduced use of chemicals Environmental risks Health risks Economic risks

17. Video Analysis Work with the person sitting next to you. 1. One look for examples of benefits of GMO’s 2. One evaluate how bias the video is Monsanto Advertisement

19. Genetically Modified?  YES  Papayas  Milk  Corn on the cob  Squash/Zucchini  “All Natural” foods  NO  Potatoes  Seedless Watermelon  Soy Milk  * Salmon

20. RTW: Happy Friday! 2/7/14  What do all of these companies have in common?

22. RTW Monday, February 10 th If you were aware of how your food was prepared, would it impact what you eat? For example-meat.

23. Food Inc.  Everybody will be assigned a question.  Throughout the documentary, take notes to reference in your response.  You can either:  Participate in a Socratic Seminar -or-  Write a paper THIS WILL BE A SUMMATIVE.

24. Socratic Seminar  Same rules as before…  However, improve it from last time!  Make movie and note references, ask “what if …?”, invite others to share.  Stay on topic- Someone bring it back!  Speak loud enough, but not over other people! Write down your thoughts you want to share when they are done.  Snowball, Piggyback.  Use the full time.  Be professional. Show RESPECT.

25. Write a Paper  Will not be pure opinion.  At least 3 different references to the documentary.  At least 3 different references to speakers during the Socratic Seminar.  Grammar counts! Rough Draft! Proof-read! Edit! Type…?  Will be due Friday the 14 th. No late work accepted! Happy Valentine’s Day

26. Food Inc. Q’s  1. Do animals have the right to a certain quality of life?  2. Should access to healthy food be a right for everyone?  3. Should companies be able to own the DNA contained in plant seeds?  4. Should a company have the power to decide what information to give consumers about the food it produces?

28. Absent/Late/Sleeping  This is a SUMMATIVE.  The “Food Inc.” documentary is available for free online. If you miss the class time showing, you have to watch it on your own time.  Use the Google. It’s there. Watch it with your family  No excuses.

29. GMO Awareness Campaign You are hired as a marketing agent to raise awareness of GMO’s 1. 1. PICK A SIDE (GMO’s are beneficial to society OR GMO’s are a 1. risk to society) 2. 2. Create a bumper sticker to educate others on your point 1. of view. 2. You need a catchy slogan 3. Pictures AND color! 4. On the back, provide three examples (evidence) supporting your cause. List where you found your evidence.
