SEV4.c Construct an argument to evaluate how human population growth affects food demand and food supply
Farming Techniques from Around the World
What's the deal with GMO's?
Compare and contrast conventional (GMO) agricultural methods to Green (organic) methods
Write out your opinion about GMO vs Organic farming
Use evidence presented today or researched to support your claim
What are GMOs?
- First approved by the U.S. government in 1996
- produced using variety of laboratory techniques including in vitro nucleic acid methods (incorporating a section of DNA, or multiple sections, into a host cell) and methods of fusing cells
-Unlike traditional plant and animal breeding, which tries to develop better varieties by selecting traits from the same species, a genetic engineering technique known as transgenesis allows scientists to insert specific genes from any plant, animal or microorganism into the DNA of an entirely different species, such as inserting fish genes into a tomato.
Differnce between GMOs and Traditional Breeding
- Selective crop breeding was accelerated by the development of crop hybridization, which crossbred plants that had desirable traits
- Breeders create hybrids by controlling the cross-pollinationof two varieties that could naturally breed in the wild.
- In the 1950s, genetic engineering techniques allowed breeders to splice genes from very different species.
-Seedless watermelons, tiny oranges and many other produce items we find at the grocery store are considered hybrids. While hybrids are usually created using low-tech, natural techniques, GMOs
are created by using complex technology and moving DNA in a way that could never naturally occur, usually across species.
How common are GMOs?
Since most corn (90%), cotton (90%) and soybeans (93%) are now genetically engineered it can be assumed that ingredients made from these crops contain GMO content.
Most of the packaged foods in American grocery stores contain GMO ingredients, and most conventional meat animals were fed GMO corn, soy or alfalfa.
Dairy products from cows treated with artificial growth hormones were the first bioengineered animal products in the food supply
Other crops that have been genetically engineered include sugar beets, canola, safflower, papaya, and squash.
Are GMOs safe to eat?
The U.S. Department of Agriculture oversees the cultivation of GMO crops, the Environmental Protection Agency regulates the pesticides and herbicides used on GMO crops, and the Food and Drug Administration is responsible for the safety of both conventional and GMO food and governs food labeling.
Current laws and regulations for GMOs were established before genetic engineering techniques were even discovered, resulting in lax enforcement, uncoordinated agency oversight and weak monitoring after the crops are on the market.
GMO foods have not been tested for long-term impacts on human
and environmental health or safety, but a growing body of research shows that biotech crops can have troubling health implications including deteriorationof liver and kidney function and impaired embryonic development.
Additionally, the FDA has no way to track adverse health effects in people consuming GMO foods, and because there is no requirement that foods containing GMO ingredients be labeled, consumers do not know when they are eating them.
Are GMOs good for the environment?
GMO crops usually use more pesticides and herbicides
than non-GMO crops, and they can easily
contaminate organic and non-GMO conventional
crops with unwanted genetic material.
Roundup Ready crops (which are engineered to tolerate application of the weed killer Roundup) are known to increase Roundup use.
Now, superweeds and pests like the rootworm have become
resistant to GMO-affiliated herbicides like Roundup and require many more toxic chemicals to be applied to crops.
Do other countries use
GMOs as much as the U.S.?
The majority (77 percent) of genetically engineered
crops are grown by just three countries: the United
States, Brazil and Argentina.
Although there are 27 countries that grow GMO crops, only 14 grow more than a million acres, with 13 countries producing only minimal amounts of GMO material.
Putting this into perspective, only 14 percent of the world’s countries are actually growing GMO crops.
Currently, nearly a quarter of EU Member States have bans on GM products.
