Transcript of GMO's Prezi

foods are altered using methods of fermentation and yeast GMO's
Genetically Modified Foods GMO video clip Thesis Statement

Genetically modified organisms (GMO’s) are an overall threat and burden to society. They negatively affect our health, environment and research is very costly. Although they have the potential to make crops more efficient and cheaper, we need to do more research to make sure that they are safe for our health and won’t cause problems down the road. A GMO label Definition of Genetically Modified Organism An organism that has been has altered by
a modified gene or different DNA. GMO's & Genetically engineered Genetically Engineered food are also a common name for GMO's. Genetically Engineered food are still genetically modified. Genetically modified organisms are not always genetically engineered however.
The 'organisms' in GMO's and GE's are just bits of DNA or proteins. The history of Genetically modified organisms GMO's in a utopia In a perfect world genetically modified foods would :
be cheap
be healthy
give off their own safe pesticides
last longer
solve world hunger The Reality in our world genetically modified foods:
Expensive (research)
not known to be any healthier
do not give off safe pesticides
obviously have not solved world hunger Pesticide resistant and pesticide producing gm crops Problems with pesticide resistant plants Problems with pesticide producing plants What could happen In the Beginning... Genetic modifying began in the 1900's
Modified through the use of yeast and fermentation
Some naturalists and farmers began to notice hybrids and played with that idea What is Put Inside GMO's Altered stands of DNA are methodically inserted into the
organisms for the desired outcome. What is inserted into the DNA Man made strands of DNA which is made out of synthetic A, T, C and G
Artificial adenine (A), guanine (G), cytosine (C), and thymine (T)
These are the chemicals that make up DNA Process Step one
You need a gene which is now synthesized
Step two
Place gene in a DNA strand that will signal the cell to except the inserted gene (often called a promoter
Step three
A second gene is inserted, often called the marker, to identify the cells that contain the gene
Step four
Deliver the modified DNA through various methods
Ex: A modified 22 rifle to shoot DNA-coated tungsten or gold particles into cells Before the 1900's ancient civilizations found certain hybrid plants,which were naturally cross bred, Health Effects of GMO's Possible health risks of consuming GMO's
Birth Defects
Digestive system effects
unknown and unpredictable future effects Fears of GMO's Future problems that are not know
Kinds of allergies that gmo's cause Cancer Risks of GMO's in a study, Rats were fed a lifetime of GM corn and trace levels of Roundup herbicide. they ended up getting massive tumors and half of the males did prematurely and 70% of the the females died prematurely. Main GMO foods Highly processed foods
Corn syrup and oils The FDA and GMO's The FDA doesn't formally approve GMO's
"Only requires pre-market approval for food additives such as dyes"(Jaffe 5) Animal meat and seeds risks of animal meat if they eat gm seeds

When GM salmon was first created the salmon were twice the size as normal salmon. Gene VI Is Gene VI really a toxin

Does it cause any health problems Economical Side of GMOS's Labeling of GMO's Whole Foods. When will the labeling of GMO's start
Why did they decide to do this Organic foods How to know a food does not contain a GMO and is organic How Would GMO's help This would help farmers make more money, make thier crops last longer and be more efficient

How much more money could farmers make? Most consumers are worried about the increased allergies of GMO's and possible toxins from the pesticides Gmo testing on mice which resulted in huge tumors Lists of food that GMO's are mainly in 1953
James Watson and Francis crick discover the shape and structure of DNA 1973
Herbert Boyer and Stanley Cohen work together to make organisms that used DNA from different species 1986
the belgians are the first to test genetically engineered crops in the field.
(Tobacco) 1987
The U.S. starts testing of genetically engineered tomatoes and tobacco 1992
The "Favr Savr" tomato is allowed commercial use in the U.S.
(approved by the department of agriculture) 1992
GMOs are declared to be safe by the FDA and dont need to be labeled in stores 1994
genetically engineered tobacco approved in France What Medical professors say Why were GM foods created? To create an advantage for the people growing and selling the food, and/or the people eating the food Genetically modified foods were introduced to shelves of grocery stores around the 1990's. when foods are cross bred, it is safe. its dangerous when we as humans take DNA from one species and put it into another even if the species are not remotely related to this day there are no laws saying that genetically modified foods have to be labeled. Environmental effects of genetically modified foods national geographic Pesticide resistant: these plants are genetically modified so that they do not shrivel up or die when pesticide is applied to them

Pesticide producing: these plants are genetically modified so that they produce their own pesticide More pesticide is able to be used (harmful to humans)
overtime the insects may become resistant to the pesticides and they will need to keep using more
livestock that feed on plants covered with insecticide have been showed to have health problems and have even died (sheep in India)
plants may cross breed with weeds making super weeds on the other hand this means less crops killed which means crops would be produced cheaper and thus be less expensive for consumers. plants may cross breed with weeds making super weeds
pollen from these crops may be moved from one farm to another and all of our natural crops could be contaminated
organisms in the ecosystems in the area of the farm may feed on crops. this could affect the whole food chain. Current/ Possible Outcomes Disease resistance
Pest resistance
Cold/Tempature resistance
Nutrition Is it Safe? WE DON'T KNOW!!! In 1992, GMO seeds were deemed "substantially equivalent" to non-GMO seeds
No government tests of safety were conducted
In fact, it is prohibited to examine whether the genetically modified crops lead to dangerous side-effects in either the environment or in animals or humans Proposition 37 Changes from the Beginning to Now The genes used to be taken from other organisms, both plant and animal, then inserted into the genetically modified plant
Now we use the synthetic chemicals to do this same task
This is safer because animals are not being used as the DNA source GM seeds are harming farmers Seeds Self Terminating Seed
Dies every year
Forces farmers to restock every year Why do consumers want labeling
How much extra would it cost companies
How much extra would the grocery bill be What is Prop 37
What was the final vote
How would it help consumers

It still wouldn't tell consumers what kinds of pesticides were used like Bt for example Differences between GMO's and Organic foods Organic foods avoids synthetic materials
no synthetics to control pests
Enhances natural processes
Traditional breeding methods GMO's Contains synthetics
Helps kill bugs that eat crops Conclusion The bad v.s the good of GMO's

Gmo's need more research to make sure they are safe for consumption and won't cause any risky effects. With more research we can also tell how they affect us currently
Genetically modified organisms (GMO’s) are an overall threat and burden to society. They negatively affect our health, environment and research is very costly. Although they have the potential to make crops more efficient and cheaper, we need to do more research to make sure that they are safe for our health and won’t cause problems down the road. caterpillars and other insects feed on gm crops. the bugs start to die off. now the birds and frogs have no food. this is a major problem and could greatly affect the food chain.
