Question

The advent of hybrid corn varieties in the U.S. in the 1920’s and 1930’s changed the agriculture industry by providing farmers with more vigorous corn varieties, thus increasing the yield.  These varieties were the result of directed cross-breeding, therefore seed had to be purchased each year to maintain the superior crops.  More recently, agricultural products such as corn and soybeans have been genetically modified to increase resistance to disease and pests, as well as create varieties of crops that are hardier (in general).  

The response to genetically modified organisms (GMOs) has been mixed with both fervent support and fervent opposition. Examples of GMOs include herbicide-resistant rice, corn that expresses the Bt toxin (which is toxic to insects of the class Lepidoptera), and corn that has been genetically engineered to produce the antibiotic penicillin.

Questions to consider:

-Some claim that genetically modified crops will ultimately help feed the world.  Do you agree?  Is it affordable and who will benefit?

-Is it ethical to add genes to species’ genomes that would not occur in nature?  What if these genes allow crops to be resistant to a common pest?  What about the decrease in the use of pesticides?

-How are native species affected?

-Is there evidence to support growing GMOs instead of traditional crops?

Explanation / Answer

Q.3 How are native species affected

Yes GMOs affected native species in several ways

Genetically modified organism [GMOs] Disrupt digestion , according to some study, transgenic crops DNA persists in human gastrointestinal tract.

Genetically modified organism [GMOs] cause cancer: in some study [international journal of biological science] give strong evidence and identified a link between the formation of cancer and GMOs consumption.

Genetically modified organism [GMOs] increase herbicide use since first time uses in agriculture, some study show that it not reduce chemical [herbicide]

And GMO also damage native species: it’s really a major point to be concerning that GMOs trait easily pass from GMO to Non-GMOs species. It give negative effect on native species, it may lead to destroyed crops or plant.

And GMOs also pollute the environment : some study they found GMOs pollute environment like BT [bacillus thuriengensis] BT found in thousand of streams or river or water-wave

GMO also destroyed befitted soil bacterial or minerals,

Q.1 Some claim that genetically modified crops will ultimately help feed the world. Do you agree? Is it affordable and who will benefit

I agree and GMOs is affordable. But GMOs is debated topic all over the world, the main benefit of GMOs food is ability to remove world hungers, biotech crops are fastest growth in agriculture field. Meanwhile too much BT crops where use in animal feeding or biofule production, genetically modified crops can reduce world hunger ratio, in African Asian countries, because GMOs crops take short period of time to grow and give higher productive yield. This GMOs crops is very useful in poor hunger country. And commercial success of the GM crop have made significant impact on the world hunger , and first GM food is Flavr-savr tomato, that reduce cost upto 20%, economically benefit to farmer.

Q.2 it ethical to add genes to species’ genomes that would not occur in nature? What if these genes allow crops to be resistant to a common pest? What about the decrease in the use of pesticides

No its not legal to add synthetic gene to species genomes because we don’t know it will benefited or harmful to livestock or animal, but research going on, scientist working on that they have all genome sequence map like rice and they are using this information to generate new gene which product protein that will increase yield productivity or may resistance to pest , yes it is possible to develop the gene and it’s product resistance to pest or may kill pest or it may work like pesticide. If we can develop a gene which can increase crops productivity and resistance to pest, so it will eventually reduce the uses of pesticides in agricultural land. Because due to presence of new gene,

Q.4 Is there evidence to support growing GMOs instead of traditional crops?

Yes there is some evidence they support GMos instead of the traditional crops, for example- soybean herbicide resistance, corn- insecticides resistance, plum-virus resistance, some food product like rice- vitamin enrichment, tabacco for vaccine, maize for oral vaccine, coho salmon faster maturation in fish and significantly increase growth, BT cotton, GMOs use in organic farming, and better taste of food    like carrot
