Specific Purpose: After hearing my speech my audience will understand the risks and
benefits of genetically modified food and why GMF are controversial, especially in the
United States.
INTRODUCTION

Attention Getter- Did you know that sixty percent of the food you eat contains
one or more genetically modified ingredients? This percentage continues to grow
every year, but could increase if the FDA lowers their already negligent
requirements on GMFs, making it easier to distribute genetically modified food.

Topic- The controversy over genetically modified food

Ethos and Audience Adaptation- As an organic gardener and a concerned
citizen, I know how difficult it is to find seeds that have not been genetically
modified or encountered genetically modified organisms. Aside from this
personal reason, I have researched genetically modified food for the past two
weeks and have read thirty articles and seven books regarding the subject.
As college students, most of us are not concerned with how our food is grown or
the farmers who grow them. But in an age where food is no longer produced
naturally, it is imperative that you know how safe our food is and the
repercussions of decisions made by biotechnologists, the FDA, and the consumer,
who all drive the market of GMFs and stock your local grocery.

Preview- In my speech I will go over what genetically modified foods are, where
they are found, the risks and benefits, and why the labeling of genetically
modified food remains problematic.
BODY
1) What are genetically modified foods?
a) GMFs are made by a technique called gene splicing
b) Gene splicing
A. Target organism’s DNA is cut & piece removed
B. New DNA from another organism inserted into the gene sequence of the
original organism
c) Why GMFs are made
A. Higher yields
B. Less susceptible to disease, drought, and pests
C. Better nutrition
a) EG: pigs with growth hormone 30% less fat(McHughen)
D. More economical
a) Use less pesticides which saves farmers money
E. Some are modified to take less time to grow and mature
F. In industrialized nations, they are usually made for a better taste
Transition: Now that I have explained how and why genetically modified foods are
made, I will now discuss where these foods are found.
2. Where genetically modified foods are found
A. 2006, 353 million acres of GMF crops in 22 countries (U.S. Dept. of Energy)
B. Majority of GMFs come from the United States
C. Common are soy beans, corn, and canola (Wholesome Goodness
Productions)
D. Genetically engineered animals found mainly in U.S.
E. Examples include:
a) Salmon that quickly mature
F. Washington State apple growers have genetically modified apples
a) First of their kind in Washington
Transition: I have now gone over where GMFs are found, we will now be covering
the benefits and risks of GMFs.
3. Arguments for the growth and cultivation of genetically modified foods
A. Those who support GMFs: agricultural businesses, bioengineering specialists,
and farmers who grow these crops
B. Their main arguments are:
a) Better taste
b) More nutrients
c) Possibility of less fat and leaner meat
C. Better for the environment due to built-in herbicides (U.S. Department of
Energy)
d) Allows farmers to spray crops with weed killer without killing crops
e) Important because 12% of crops grown are destroyed by weeds (Thomson)
C. Providing food for poor countries
D. Health for poor countries
a) Some foods that could help poor countries:
I. Golden rice (Vitamin A)- can prevent night blindness in children
and other vision problems (Wholesome Goodness Productions)
II. Peaches and apples that can provide immunizations to poor
countries
Translation: While these benefits are very compelling, one must also weigh the
consequences when deciding whether growing and raising GMFs are worth the
consequences mentioned below.
4. Arguments against the growing and raising of genetically modified food
a) Damaging to the food web
A. Destroying beneficial pollinators
B. Experiment conducted in 1994
a) Monarch butterfly larvae ate milkweed dusted w/ GMF corn
pollen
b) Pollen was toxic- death rate of 44% (Letourneau and Burrows)
b) Gene drift
A. Process of genes from genetically modified crops and animals that enter
the DNA of another non-modified organisms
B. Crops- genes escaping via spillage of seeds (McHughen)
C. Possibility of gene drift to other plants
a) creation of super weeds
b) hybrid plants- genetically modified plants mixing with wild
relatives via cross pollination
c) Allergens
A. New DNA can cause allergic reactions
B. Testing for allergens involves taking sample and testing it in a database
C. Problem if new components aren’t in database
d) Ethical questions in terms of animal gene manipulation
A. Causing pain and discomfort to the animal is considered an inappropriate
use of genetic manipulation
a) EG: Beltville pigs were inserted with human growth hormones
which caused severe arthritis, spinal deformities, and blindness
(Nottingham)
e) Seed companies creating a monopoly over selling genetically modified seeds
A. Monsanto is the world’s largest genetically modified seed distributor
B. Patents are also a problem, because many companies who create GM
seeds get patents
a) EG: Monsanto owns 11,000 patents (Garcia)
C. Monsanto seeds have terminator genes, which are genes that prevent the
seed from being saved because they prevent them from growing for more
than one season ( Lambrecht)
D. Thus through patents and terminator genes, farmers are forced to buy more
seeds from Monsanto
Translation: With that said, my last area of discussion is that of labeling genetically
modified food, which isn’t as simple as most people think.
5. The problems of labeling genetically modified food
a) The FDA does not require genetically modified food to be labeled
A. GMFs receive the same considerations as other foods because they are the
same (U.S. Food and Drug Administration)
B. Only time they must be labeled is if they contain an allergen or have a
different nutritional profile
b) Labeling GMfs would cost more money in exports
A. Segregating genetically modified and non-genetically modified foods
would cost money in exports
B. Countries, such as Britain, require all foods to be labeled as such
(Marchant, Gardineau, Redick)
c) General public doesn’t know enough information about genetically modified
foods to make an informed decision
A. Some people consider GMFs as “frankenfoods”
B. Difficult if multiple ingredients are modified (McHughen)
C. If they are to be labeled, the population must be informed
CONCLUSION
o Signal- While genetically modified food is a complicated topic to understand, it is
our job as citizens to decide whether to allow the FDA to make this important
decision for us. Obviously, there are multiple perspectives that must be
considered and the repercussions of each.
o Summary- In this speech I have explained how genetically modified foods are
made, where they are found, the risks and benefits, and the problems of trying to
label genetically modified food.
o Closing- I hope now with this information that you are able to make an informed
decision about where you stand on this controversial and important issue.
