Answering some questions about GM foods

1. Answering some questions about GM foods Presented by Glenn Ashton

2. You and your genes - We are what we are because of our genes

3. Just what is a gene? Original scientific sketches from Jana Klose, Greg Lampard, UBC Biotechnology Laboratory

4. Cell Plant cell A single gene Extracted DNA Transformation Cell division Transgenic plant How do we engineer genes? Original scientific sketches from Jana Klose, Greg Lampard, UBC Biotechnology Laboratory

5. Why is GE/ GM different? • Conventional breeding can only work in related species, • Genetic engineering breaks species boundaries allowing inter-species genetic transfer, • Crude, invasive process reliant on outdated concept of genetic determinism.

6. Biotechnology / GM Biotechnology is: • Harnessing the natural biological processes of living systems for the benefit of mankind. • Biotechnology in the past: • making bread and cheese, brewing beer, yoghurt • crossbreeding plants • Modern biotechnology: • genetic engineering, marker assisted breeding, gene silencing.

7. What are we engineering? • Maize – inserting insect resistance (Bt) and chemical (weedkiller/ pesticide) resistance (HT): 80% GM in SA. • Soy – chemical resistance: 80% GM • Cotton – insect resistance: 98% GM • Canola – chemical resistance: 0% in SA. • No fruit or veg in South Africa, but squash, pawpaw and eggplant elsewhere. • We eat the world’s first GM staple – white maize.

9. Do we need GM crop technology to feed the world? • More people need more food? BUT GM crops do not yield higher than conventional! • Use less chemicals, better for the earth? BUT GM crops use more chemicals than conventional! • We need to insure ourselves against climate change? BUT No GM crops are drought resistant or offer any such advantage!

10. Have GM crops lived up to the hype? • 15 years of GM crops have not increased yields, • Neither have they provided more ecologically sustainable farming methods, • Nor have they reduced hunger globally, or in South Africa, • They benefit farmers by making industrial farming easier, saving labour and time, • Consumers bear all the risks without being informed of existence of GM ingredients in food, • There are no nutritional benefits but there are risks: http://indiagminfo.org/?attachment_id=557

11. Some questions to ponder: • Is this strictly a scientific issue; or are the human, spiritual, economic and moral questions equally or more important? • Is GM food technology properly regulated and tested? • Do we really need to use GMOs to feed the world? 15 years of GMO crops has seen increased food prices • Can we not produce and distribute food more equitably? • What role will the community play in the future debate? • How will they express their concerns and demand their rights?

13. Where to from here? • Eat food your grandparents would recognise: Most GM crops used in industrial farming/ food, • Demand identification of GM ingredients as per Consumer Protection Act (above 5% must be labelled), • Look toward alternatives; difficult if cost prohibitive, • Know your food and its sources, • Slow food is an emerging response to industrial, GM food.

14. Where is local GM food? VEGETABLE OILS; Canola, Cotton, Soy, Corn Oil or Oil labelled as “vegetable oil”. SOYA Processed foods, Hydrolysed Vegetable Protein Textured Vegetable Protein (TVP), Vegetable Protein Extract, Soy Protein, Lecithin Emulsifier, Lecithin, ‘Emulsifier’, Tofu, Tamari, Shoyu, Tempeh, Soya Sauce,Soy Fibre. MAIZE; Samp, Mielie meal, Corn or Maize Starch, Glucose syrup, Starch, Modified Starch, Thickener, Corn/Maize Flour, Corn Flakes, Cereals, Snack foods. CANOLA Canola, Canola Oil, Margarine, Butter/Oil spreads (imported) POTATOES Starch, Potato starch, Potato Flour (only imported) COTTON DERIVATIVES Cottonseed oil (widely used to fry ‘fast /convenience foods), Cotton Linters (often used to make sausage casings.) LOCALLY PRODUCED MILK, CHEESE, BUTTER. The use of RBGH or BST, genetically engineered hormones is banned around the world and used to be widespread in SA.

16. Or the beginning? Is this the end? “Food for all is a necessity. Food should not be a merchandise, to be bought and sold as jewels are bought and sold by those who have the money to buy. Food is a human necessity, like water and air, it should be available.” Pearl S. Buck.
