Definition: Genetically Modified Organisms or Food (GMOs) are plants and animals into which scientists have inserted foreign genes for specific, desired traits—such as cold tolerance, insect resistance, drug production, or immunity to common pesticides. GMOs are usually designed to carry one or more genes from a totally unrelated species to another. For instance, in designing cold-tolerant tomatoes, some crop developers have put into the fruit's cells an antifreeze gene from flounder. Ordinarily, crossing such species would be impossible, and even crosses of related species can yield infertile offspring—like the mule from the mating of a horse and donkey. Unlike the mule, however, GMOs remain fertile. This high-tech approach is different from conventional plant or animal breeding for desired traits, in which individuals of a species are repeatedly crossed to bring out what the breeder is looking for in a domestic animal or crop plant.
Pros: Despite their potential risks, GMOs offer great benefits to developing countries, according to the U.N. Environment Program. Certain GMOs reduce the need for precious resources, such as water, fertilizer, or pesticides. This technology offer greater yields than conventional crops.
Cons: There are many concerns over the safety of these foods as well as the seeds from these plants. Studies have demonstrated that foreign genes in crop plants don't always stay put. Pollen from such plants might carry inserted genes from modified soybeans, for instance, into a field of wild soybean plants or an unmodified crop. The unintentionally broadcast genes could come to dominate in future generations of the wild or supposedly normal crop plants and thus reduce genetic diversity in the species.
Side effects: The potential of genetically engineered foods to cause allergic reactions in humans is a big reason for opposition to such crops. Although protocols are in place to ask questions about the allergy-causing possibilities, there has been no test that offers definitive answers. But all of that could change as a Michigan State University researcher has developed the first animal model to test whether genetically engineered foods could cause human allergic reactions.
Discussion: Where do we stand with this technology that is beneficial on one hand but may harbor potential safety issues? Safety should be our number one concern and preparing for the future food needs of our growing world population should be another. Where do you stand on this issue?
I doubt I'll ever be on board with GMOs. I don't want them and I wouldnt offer them to anyone (that I actually liked). However, with that being said... the research and studies are fascinating.

I think it's wrong, we should not play with God's creations. This food is not natural and it does more damage than you think.
They are only doing this because they need cheaper food for more people, but they are destroying the quality of the food. Have you ever tasted GM tomatoes? They taste nothing like the natural ones.

Great article by the way.
I just can't help but be against almost anything genetically modified though. It's terribly creepy and obviously, well, unnatural. I also think that the cons overrule the pros in this case. I sincerely feel that this should be left alone and we shouldn't really interfere with the natural course of organisms, one thing is evolution and another is actually getting in there and mutating plants or animals ourselves.
Thanks for the excellent info, stay green. :)
The idea of GMO's are good and relavent, but I dont think that the con's tilt the scale in a possitive dirrection. Yes we do want to help our enviorment and people of our world, but are we willing to take a risk on genetically altering foods to do that? Risking people and possibly animals lives?
Everything was made unique for a reason. And we should keep it that way!
It obviously sounds wrong and its' controversy will indisputably scare many people off, but if genes can be manipulated in this way to make crops grow in marginal areas, then it's not such a bad thing because don't we all want to get rid of world hunger? But of course one can only speculate if it will in fact be used to serve the third world.
It's beyond what nature intended! If scientists cross breed a crop with an insect to make it bug resistant than we are literally eating a crop part insect–a mutant crop!
GMO crops become super weeds taking over the natural environment, we can't rotate crops, the land becomes exhausted.... and the GMO crops won't die ever!
Do what you can to eat organic, our bodies and our brains need real food, not chemically inflicted food that doesn't naturally occur on our planet.
Eat organic! Put it to the test and you'll feel like new person!

According to a really helpful paper i read, "Ecological and Social Impacts of Fast Growing Timber Plantations and Genetically Modified Trees", GE trees (which are GMOs):
- according to Nature, Bt was found by researchers to exude from plant roots, bind to soil, and remain in an "active, lethal state" for more than seven months mainly due to high concentrations needed for the Bt crops' success.
you can find this paper and more information at: www.dogwoodalliance.orgI believe GMO has impacted our society in many great ways. Here is two main ones:
First off, medicine. Most anti-biotic, enzymes, vitamins, vaccines etc are produced by GMO. There just isn’t enough time and resources to produce these medicine. Furthermore, because it is produce in a lab setting, it can be monitored closely.
Secondly, it saves a lot of resources. Take for an example cheese. Most cheese requires an enzyme to change milk into cheese. This enzyme is found naturally in a goat's stomach. Meaning you need to store the milk in a calf's stomach to make cheese. I personally think that is rather unhygienic and very impractical (I mean how many calves are you going to kill?). Fortunately most cheese company thinks so also. Most of the cheese on the market, in US anyways, are made using an enzyme produced from a GE microorganism. The only cheese not produce that way are organic cheese which are produce in the traditional way (in a calf stomach) or vegetarian cheese where the enzyme is produced from a fungus but tastes different. Overall, most GE crop is made because of better yield or just uses less resources, ie water, soil, pesticides.
As for cross pollination, isn’t that a problem in general? Agricultural crops in general are a danger to biodiversity. Historically, agricultural plants are selectively picked because they have a much higher yield. GMO is the same thing just more effectively. Having GMO does not introduce a new danger when the danger of cross pollination is already there. Just because the plant is a GMO does not mean it would have a greater chance of being cross-pollinated than any other agricultural plant.
Furthermore, GMO does NOT mean it is toxic. GMO is genetically modified organism. By recombination, it only changes a particular gene or two (depending on the phenotype) to make the organism a more useful organism. This recombinant process does not produce any toxins. Furthermore, GE food are tested before it ever goes on the market as like other food and to make sure its properties is like others.
Most GMO's are toxic because they are sprayed with pesticides. They are not pure in form either, so you may not be getting all the nutrients and antioxidants as nature intended. I am reading this fascinating book
Omnivores Dilemma. Fascinating stuff.
Just because it is tested does not mean it is safe or healthy. Do not be fooled.

I prefer to eat naturally grown produces.

I always try to eat organic foods. The cost is quite prohibitive somethimes though, but prices are coming down.
A recent editorial in Scientific American, reveals the shocking and alarming reality behind the proliferation of GMO products throughout the food chain of the planet since 1994. If you are interested in learning more about GMO's, it is certainly worth checking out. It was the August 2009 issue, if I am not mistaken.
There have been studies that show a direct relation to GMO crops and the 100% disappearance of Monarch Butterflies-
