  1. GMF - Risk vs. Reward Genetically Modified Food By: Robert McDougall IS195 – Roberto Clemente School rmcdougall@schools.nyc.gov March 11, 2011

  2. What is Genetically Modified Food • GMF for short • Definition: • Food from agricultural biotechnology and crops that have been genetically altered by scientists. • Genetic modification involves the creation of plants and animals that are genetically different from any preexisting plants or animals. • The process of genetic modification, often called transgenics or DNA recombination, occurs when bio-chemists take desirable genes from one plant or animal and insert them into the genetic material of another plant or animal with the purpose of exploiting a trait from the original organism

  3. Risks What are the disadvantages to GMF • Environmental activists, religious organizations, public interest groups, professional associations and other scientists and government officials have all raised concerns about GM foods, and criticized agribusiness for pursuing profit without concern for potential hazards, and the government for failing to exercise adequate regulatory oversight. • Most concerns about GM foods fall into three categories: environmental hazards, human health risks, and economic concerns. • Unintended harm to other organisms • Reduced effectiveness of pesticides • Gene transfer to non-targeted species • Allergenicity • Unknown effects on human health • Economic concerns • Cost to produce • Cost of seeds • Patent enforcement • Who will have access to it?

  4. Rewards What are the advantages to GMF • The world population has topped 7 billion people and is predicted to double in the next 50 years. • Ensuring an adequate food supply for this booming population is going to be a major challenge in the years to come. • GM foods promise to meet this need in a number of ways: • Pest Resistance • Herbicide Tolerance • Disease Resistance • Cold Resistance • Drought/Saline Tolerance • Nutrition • Pharmaceuticals • Phytoremediation

  5. Who Uses GMF? Are GMFs Safe to Eat? • According to the FDA and the United States Department of Agriculture (USDA), there are over 40 plant varieties that have completed all of the federal requirements for commercialization. • Some examples of these plants include tomatoes and cantaloupes that have modified ripening characteristics, soybeans and sugar beets that are resistant to herbicides, and corn and cotton plants with increased resistance to insect pests. • The prevalence of GM foods in U.S. grocery stores is more widespread than is commonly thought. While there are very, very few genetically-modified whole fruits and vegetables available on produce stands, highly processed foods, such as vegetable oils or breakfast cereals, most likely contain some tiny percentage of genetically-modified ingredients because the raw ingredients have been pooled into one processing stream from many different sources. • The ubiquity of soybean derivatives as food additives in the modern American diet virtually ensures that all U.S. consumers have been exposed to GM food products.

  6. Who Uses GMF? How widespread is the usage of GMF • In 1994, the first genetically modified crop - a tomato came on the market in the USA. Since then there have been many more. Eating genetically modified food has become quite common. • People have only been eating genetically modified food for a relatively short period. So there may be long-term effects which we simply don't know about yet. • Americans have eaten genetically modified foods for the longest period. Today they eat genetically modified food produce every day. • It's estimated that around 65% of the products available in American supermarkets contain some amount of genetically modified ingredients. • Surveys in the USA have shown that many Americans have a relaxed approach to genetic modification. They reason that it must be safe because they've eaten it for years without getting sick.

  7. How are GMF’s Regulated? What is the Government’s Role? Governments around the world are hard at work to establish a regulatory process to monitor the effects of and approve new varieties of GM plants. Depending on the political, social and economic climate within a region or country, different governments are responding in different ways.

  8. How are GMF’s Labeled How will you know if you are eating GMF? • People have the right to know what they are eating, argue the interest groups, and historically industry has proven itself to be unreliable at self-compliance with existing safety regulations. • The FDA's current position on food labeling is governed by the Food, Drug and Cosmetic Act which is only concerned with food additives, not whole foods or food products that are considered "GRAS" - generally recognized as safe. • The FDA contends that GM foods are substantially equivalent to non-GM foods, and therefore not subject to more stringent labeling. • If all GM foods and food products are to be labeled, Congress must enact sweeping changes in the existing food labeling policy. • An international trade agreement for labeling GM foods has been established. More than 130 countries, including the US, the world's largest producer of GM foods, signed the agreement. • The policy states that exporters must be required to label all GM foods and that importing countries have the right to judge for themselves the potential risks and reject GM foods, if they so choose. This new agreement may spur the U.S. government to resolve the domestic food labeling dilemma more rapidly.

  9. Can You Tell? Which of these foods is genetically modified?

The Great Debate Step1 Pick your Position “Pro or Con for GMF” Define the Problem Use the Websites to gather information to support your position Students will be given 20 minutes to research their position. Next class period will be the GMF Debate! Are you For or Against the use of GMF Gather Information and Evidence to support your Position For or Against GMF. Pick a Position Step 2 Research Debate
