Genetically Modified Foods
What are GMOs?
• What does GMO stands for?– Genetically Modified Organisms
• GMO Definition:– Genetically modified plants and animals created
by moving desirable genes from one organism or species to another
• GMOs are also known as Transgenic organisms
Genetically modified food can help decrease world hunger & disease
Golden rice: is rice that has been genetically altered using
genes from daffodils and a bacterium. The result is rice that has high vitamin A and help
prevent blindness
Golden Rice
Herbicide-resistant Crops…
• Crops are genetically altered to make them resistant to weeds & this decreases the amount of chemical herbicides that have to be used (good for the environment!)
Insect-resistant Crops
• Created when scientists took a gene from a soil bacterium, modified it, and introduced it to plants
What HAPPENS?• Transgenic plants can now produce a toxin to
kill specific types of insects
Top 5 Countries who use GM crops
1)USA (63%)2)Argentina (21%)3)Canada (6%) Canola, Corn & Soybeans
4)Brazil (4%)5)China (1%)
Genetically Modified Animals
*They are developed to grow faster and resist disease*
Transgenic cows produce more milk on less feed
Genetically Modified Animals
Sheep, cows and pigs can even be modified to produce higher levels of protein = more meat.
“Frankenfoods”
What are some arguments
against GMOs?
“Frankenfoods”
Arguments…..
• The development of “Superbugs”, which are resistant to pesticides
• Long term effects of GMOs are unknown• Who owns agricultural advancements?
-What about developing countries?-Farmers need to purchase hybrid
seeds?
Terminator Plants
• These plants are genetically engineered so that they kill their own seeds
• Farmers need to purchase new seeds every year, instead of allowing their crops to pollinate naturally
Transgenic Fish
What could happen if Transgenic fish escaped?
Europe and Transgenic Foods…
• In North America, many of us are not aware that we are eating transgenic foods as labeling laws DO NOT EXIST
• In Europe, labeling laws require GMO foods to be labeled
• Europeans are far less accepting of Transgenic Foods
Time for a Video….
Take out a piece of paper and make a T-chart
