This document discusses genetically modified foods (GMFs). It provides a brief history of genetic modification, including the creation of the first transgenic plant in 1983. Commercially, four GMF crops - soybeans, maize, cotton, and canola - dominate global agriculture. While GMFs promise benefits like increased nutrients and crop protection, there are also risks to human health from allergic reactions and toxic effects. Additionally, GMFs can reduce biodiversity and lead to environmental problems through increased pesticide and herbicide use. The economic and social impacts of GMFs are an ongoing topic of debate.
2. GENETICALLY MODIFIED ORGANISMS
Genetically modified organisms (GMOs) we can define it as
organisms in which the genetic material (DNA) has been
altered in a way that does not occur naturally.
The technology is often called “modern biotechnology
“genetic engineering”.
It allows selected individual genes to be transferred from
one organism into another, also between non-related
species.
3. History
of GMO
1982 First transgenic animals (mice)
produced.
1990 First transgenic cereal plants (maize and
wheat)
1993 Regulations for deliberate release of
genetically engineered organisms.
1994 Genetically engineered tomato marketed in
USA.
2004, genetically modified crops were
being grown by 8.25 million farmers in 17
countries
The 1980’s marked the
scientific discovery that
specific pieces of DNA
could be transferred from
one organism to another ,
This became the basis of
the genetic modification
process.
In 1983, the first transgenic
plant, a tobacco plant
resistant to anti-biotics was
created
Some Revolutionary Periods
4. The promise of genetic modification , when scientist
discovered that the modification process could be
used to
1- introduce nutrients and vitamins to enrich foods
2- improve crop protection
3- in order to create or enhance desirable characteristics
from the same or another species”
4- introducing natural pesticides and insecticides through
genetic manipulation decreases using of chemical
pesticides & insecticides
5- to produces higher yielding, heartier plants that are more
adaptable to soils and climates and require less water to
grow
5. In 1983, the first transgenic plant, a tobacco plant resistant to
anti-biotics was created
6. . Commercially, four genetically modified crops
dominate global biotech agriculture
soybeans
accounting for 60% of GM
crop area
maize accounting for
23% of GM crop area
cotton accounting
for 11% of GM crop area
canola accounting
for 6% of GM crop area

9. Here are seven of the dangers that have been
discovered by consuming genetically modified food
1. Food Allergy Symptoms Increase Dramatically
2. Bodily Toxicity Increases
3. Negative Reproductive Effects
4. Negative Effects To Digestive System
5. Unknown Genetic Effects On Humans
6. Death of insect and some of animal
7. Mutation
10. How are the potential risks to human
health determined?
Human health risk so Unfamiliar foreign proteins e.g. allergic
reactions
Genes resistant to antibiotics e.g. dangerous disease transmittable
to humans
Some carcinogenic properties causing cancer (long term effects)
Toxic compound (glyphosphate in Roundup) harming
development in children and adult
The golden rice with more beta-carotene has too much of a
pigment called xanthophylls, and the rice with less glutelin has
more of the protein proclaim, which can be an allergen.
Ethical concern (Religious)
Money cost approbation
Antibiotic resistant
Resistant weed
11. DISADVANTAG
Reducing biodiversity
GMO is the uncontrolled process because the site of insertion random and many potentially
damage the plant’s genetic makeup
The mutation that occur during the genetically engineering can lead to many unexpected
changes in a resulting crops such as
1- poor crops performance 2- alteration in food’s nutritional content
3- toxic & allergnic effects
Not safe process Very little testing has been done on GM foods.
genetic engineering is a new field, and long term results are unclear
funding only given to tests which show positive results.
12. Environmental problem
According EPA investigation
GMF
Increase use of pesticide and herbicide that is effect the wildlife
Gm dose not help the Clemet changes
GMO also depend in the nitrogen fertilizer which increase the greenhouse
gases
glyphosate depletes soil quality by killing the natural nutrients and organisms
that are necessary for plant development leading to plant diseases ,
glyphosate is highly invasive and can mixed with rain , air ,water soil and
ground water
13. Economic Effects
Genetically modified crops
may also lead to beneficial
economic effects
- Increased crop yield and
quality
- Subsequently increased
profit
14. Conclusion
GMO’s present both positive and negative aspects
to society as a whole
They are a topic of much deliberation and tension;
very prevalent in some parts of the world and
banned in others
Ultimately, GMO’s are still a relatively premature
technology and in the developmental process. Only
time will reveal their ultimate effect on humans.
15. GM Restricted Countries
Africa: Algeria, Egypt
Asia: Sri Lanka, Thailand, Japan, Philippine
Europe: Norway, UK, Spain, Italy, France
Middle East: Saudi Arabia
Pacific: Fiji, Australia, New Zealand
