Transcript of Genetically Modified Organisms

Genetically Modified Organisms

What are GMOs?
*
GMOs are plants (foods) or animals that have been genetically engineered with DNA from bacteria, viruses, or other plants and animals. These genetically engineered organisms can not occur in nature or in traditional crossbreeding.
What is the purpose of GMOs?
History of GMOs
* In 1935, DNA was discovered.
*First recombinant DNA molecules were produced by Paul Berg in 1972.
*Most GMOs are created for medicine, agriculture, and pest control, or to create an organism with a focus on specific traits.
Are GMOs safe?
*Most nations do not consider GMOs safe and place significant restrictions or bans on production and sales of GMOs because they produce health problems and environmental damage.
Are GMOs common?
*Genetically modified animals are not very common, but genetically modified plants are in 80% of conventional processed foods in the US.
Main issues of concern for human health.
*GMOs can provoke allergic reaction and can cause damage to vital organs.
Impact of GMOs on the environment
*GMOs are responsible for emergence of super weeds and super bugs that can only be killed with toxic poisons.
*Toxic herbicides have increased 15 times since GMOs were introduced.
*Once GMOs are released into the environment, they can not be recalled.
What kind of genetically modified foods are on the market?
*All crops that resist insect damage, viral infections, and tolerance towards certain herbicides are on the market.
What laws are placed on GMOs foods in the US?
*Very flexible law.
*FDA, USDA, and EPA are the three US agencies responsible for the release of genetically modified food plants.
*Safety testing on genetically modified goods is voluntary by the FDA as long as the product is not significantly different from other GMOs.
Genetically Modified
Animals
*Involves altering an animal's genetic material by adding, changing, or removing certain DNA sequences in a way that does not occur naturally.
*Goal is to produce an organism with specific traits that are most often desired.
