2What It Is
- Genetic alteration is a process in which the DNA
from one organism is inserted into the DNA of
another organism, allowing the traits of one
organism to be realized in the other. - This technology has allowed such things as
strawberries that grow in the winter, tomatoes
that fully ripen on the vine without rotting, and
crops that are resistant to bugs and herbicides.
3How It Works
- Genetic Alteration can be explained most
basically as a process of cutting and pasting. - First a gene segment is removed, or cut, from a
chain of DNA . - The gene segment is then inserted, or pasted,
into the DNA of another organism.
4Background
- Crop alteration has been present in agricultural
societies for the past 4000 years. - First modern crop alteration occurred in 1994
with the development of the Flavr Savr Tomato. - Currently over 22 percent of crops worldwide are
genetically altered.
5Background
- Currently, over 145 million acres world wide are
growing genetically altered crops. Most of which
are in the United States. - Crops are most often altered to be pest or
herbicide resistant.
6Background
- Today the most common genetically altered crops
grown in the United States and world wide are
corn, soybeans, and cotton.
7Why alter crops?
- Genetically altered crops can produce greater
yields. - Pest and herbicide resistant crops can
dramatically reduce the need for chemicals and
thus benefit the environment. - Crops can be altered to be healthier and more
beneficial to humans. Example golden rice.
8Case Study Bt Crops
- Bacillus thuringiensis (Bt) is a common soil
bacterium that produces crystals that are toxic
to insects. - First discover in Japan in 1901 in dead silkworm
larvae. - First commercially used in the U.S. in 1958. Used
by 95 of the market by 1989. - Today, 34 different subspecies and 800 strains
are used. - Most commonly used on corn, potato, and cotton
crops. -
9Case Study Bt Crops
- Benefits
- Kills off insects without the use of pesticides.
- Only requires one time application.
- Not harmful to humans.
- Farmers found a 7 yield increase.
- Reduces on-farm costs (92 million in 1998).
10Case Study Bt Crops
- Costs
- Insects may develop a resistance to Bt sooner.
- Beneficial animals may become sick due to
ingested infected insects.
11Case Study Bt Crops
- In 1995, the first Bt crops were approved by the
EPA. - In 2002, The EPA reassessed BT crops and
continued to approve Bt crops. - Current laws require the registration of Bt
crops.
12Case Study Bt Crops
- Conclusions
- Bt crops are cheaper and have better yields than
traditional pesticides. - Bt crops are extremely safe.
- The costs are the same as with any other
pesticide. - Bt crops is the best option.
13Ethical Issues
- Does Genetic engineering respect the intrinsic
right of other creature? - Are the risks to the environment and human health
from genetic engineering serious enough to
warrant a moratorium on deliberate release of
genetically modified organisms at this time? - What happens to the gap between our contemporary
rich and poor world? - How about respecting the rights of a third wold
people who have promoted bio-diversity over
thousands of years? - Is it proper to claim ownership over a living
organism?
14Legal Issues
- Products dont require pre-market approval
process, public notifications, or labeling. - Companies conduct safety test for their own
bio-engineered products, notifying the FDA only
if they suspect a problem. - No way to trace who or what is responsible should
a problem occur. - FDA policy forfeit consumers right to know how
their food has been manufactured, and also the
publics right to safe and tested food products,
by allowing the companies to decide if and when a
product is hazardous.
15Legal Issues (cont.)
- High ranking personnel from the corporate would
move into critical position in the FDA and then
back to the industry. - A revolving door between the US government and
the biotech industry. - Heavy lobbing to rewrite World Food Safety
standards in favor of biotechnology. - New laws protecting the US food industry from
criticism.
16Professional Issues
- Making sure everybody works to a maximum benefits
- Technological advancement
- Jobs of genetic engineers
17Professional Issues (cont.)
- Advantage
- improve the yield of crops in a cost effective
way. - produce high quality crops.
- decrease of pesticides being used which will
decrease damage of our environment. - avoiding of meaning less chemicals being digested
by people. - Disadvantage
- initial cost of the procedure as glasshouses.
- training for the maintenance of Bt genes
- it can escape into another agriculture
- food could be harmful to both animal and human
health - not knowing what we are messing with
18Stakeholders
- Consumers
- Animals
- Insects
- Farmers
- Engineers
- Companies
- Government agencies
- Environmental groups
19Possible Actions
- Use unaltered crops
- Conventional farming
- Use altered crops but with regulations
- Use labels and enforce tolerance limits of how
much BT is used
20Utilitarianism
- Hypothetical risks are weighed against future
benefit - Even though it has an enormous benefit in the
future, the customers have the right to know what
they are getting which will help both sides.
21Rights Perspective
- The consumer has the right to know what they are
purchasing - Choose between GM and Organic
- We all have the right to adequate food
- Farmers have the right to protect their crops
- Tolerance limits?
- Who will in force it?
- GM better than general insecticides
22Fairness/Justice Perspective
- GM can produce higher yield
- More product ? less expensive
- Keep the work environment healthier
- Not to be exposed to insecticides
- Higher cost for seed
- Fair to the smaller farmer?
23Common Good Perspective
- Lower cost ? more affordable
- End world hunger?
- End malnutrition
- Improve amino acid balance
- Improve iron and vitamin A intake
- Potential to lower the use of insecticides
- Insects can build a resistance
- SUPER BUG
24Virtue Perspective
- Honesty
- Have to trust those that produce the crops
- Safety of the public is more important than money
- Respect
- Care for the land
- Try not to destroy surrounding ecosystems and not
to harm non targeted wildlife within the
production land
25Consequences Perspective
- If GM crops are not used than the cost will
increase - Poor will not be able to afford
- Frankenstein Foods
- Random gene insertion
- Can produce new allergens
- Eating DNA!!!
26Kantian Perspective
- Right to adequate food
- Right to a safe environment
- Right to know what is contained in the crops
- Right to protect ones property
27ConclusionThere are risks inherent in any
technological intervention. Human beings down the
centuries have learned to weigh the perceived and
real risks against the benefits of emerging
technologies, and have responsibly integrated
these to foster progress. For instance, the use
of electricity, automobiles, air travel, and even
immunization all involve some risks, but this has
not prevented humankind from benefiting from
them.-C.S. Prakash
