So what really is a GMO and what is the difference between it and a hybrid?  Vicki

GMO is a genetically modified organism. For example, they have changed the genetic structure of "Round-up Ready" corn and soybeans so that Round-up doesn't kill them and they can then just blanket spray fields to kills weeds and not have to worry about killing the crops. With a hybrid, they have taken existing strains of a plant and crossed them, sort of like breeding mini-goats, for example. Now, your GMO's are going to necessarily be hybrids also, but hybrids aren't necessarily GMOs. The thing about a hybrid plant is that they won't breed true...seeds saved from a hybrid tomato, say, will still give you tomatoes, but they won't necessarily be like the plant that you saved the seeds from. Heirloom, open pollinated plants, will breed true to the "parent"...if you save seeds from a Brandywine tomato, you will be able to grow more Brandywine tomatoes,  unless they were cross pollinated by a different variety. Different types of plants are pollinated in different ways, and so have different requirements for how you grow them in order to be able to save seeds that will be true to the original plant.

So if you plant GMO seeds you get what...and what is so bad about GMO seeds?

You get GMO plants. And technically, you can't save seeds from those plants because the company that designed them owns the patent and doesn't give you "permission" to use their genes. Which is why Monsanto spends time going after farmers who try to save seeds...they're supposed to buy new seed every year from Monsanto. Even farmers who plant non-GMO corn can have their corn crop contaminated by pollen from the neighboring farm's GMO corn (since corn is wind pollinated) and then Monsanto can actually even go after them and if the seed that they saved is found to contain Monsanto genetics in it, well, let's just say it's not pretty.

As to what is bad about GMO seeds, one concern is that we don't know the long term effects of the consumption of genetically modified foods. And with the Round-Up Ready seeds, we then are certainly increasing our exposure to herbicides (since they now can be sprayed on the crops without worry that the crops themselves will suffer). Also, we don't know if herbicide resistant crops might not cross pollinate with weeds, creating herbicide resistant weeds. Some corn has been engineered to contain pesticides to protect it from corn earworms, but it might also adversely affect not target species, such as monarch butterflies, or if this might lead to pests being resistant to the pesticides. There is just so much that we don't know about the long term safety of GMO crops.

Interesting article here: http://www.csa.com/discoveryguides/gmfood/overview.php

One of the things that I found very interesting in that article was a brief discussion of the different regulatory agencies in the US that are charged with determining the safety of GMO foods and how the whole thing doesn't seem to be very effective:

Quote
In the United States, the regulatory process is confused because there are three different government agencies that have jurisdiction over GM foods. To put it very simply, the EPA evaluates GM plants for environmental safety, the USDA evaluates whether the plant is safe to grow, and the FDA evaluates whether the plant is safe to eat. The EPA is responsible for regulating substances such as pesticides or toxins that may cause harm to the environment. GM crops such as B.t. pesticide-laced corn or herbicide-tolerant crops but not foods modified for their nutritional value fall under the purview of the EPA. The USDA is responsible for GM crops that do not fall under the umbrella of the EPA such as drought-tolerant or disease-tolerant crops, crops grown for animal feeds, or whole fruits, vegetables and grains for human consumption. The FDA historically has been concerned with pharmaceuticals, cosmetics and food products and additives, not whole foods. Under current guidelines, a genetically-modified ear of corn sold at a produce stand is not regulated by the FDA because it is a whole food, but a box of cornflakes is regulated because it is a food product. The FDA's stance is that GM foods are substantially equivalent to unmodified, "natural" foods, and therefore not subject to FDA regulation.

You can watch this movie for free on your computer on Hulu.  It goes into depth about how GMO's are made and some future probs they may present.  I knew most of what the first half of the movie presented but the second half was a real eye opener.

And they wont stop at this, making Money is what Monsanto and Dow and the big ag companies do, they made agent orange then couldnt do anything with it after the war....so they used it to spray our crops...90 percent of anything you buy packaged and processed is made of corn and all that Roundup is sprayed on your corn.  We are the biggest consumers of corn and dont even know it most of the time.  GMO is playing God without knowing what the long term issues may or may not be.  If farmers were paid what they should be and grew real crops instead of see sawing with corn and soy beans America could feed the world with very little effort, but mono cropping is not sustainable, practical or reasonable, however Big Ag can make it pay for their shareholders which is the only thing they really care about.  You have to really look anymore to find seed companies who do not allow GMO seeds into their catalog and seed bank. FedCo Seeds, Baker Creek are the only places I get my seeds.

One reason I don't care for GMO is that studies have shown it significantly reduces the fecundity (like to almost nothing!) of animals over only 3 generations. I had enough trouble getting pregnant (well, the first time anyway Smiley ) that I don't want my children or grands to have fertility struggles just because of the food I fed them. Now remind me next spring to grow enough corn to supply tortillas all year round Smiley

Also, when you ask the animals which they prefer it is always the non GMO plants. It is true for honey bees, deer etc.

The gene strains they use to modify the plant is often taken from an animal ( very strange! ) and injected into plant genes. I think some fish genes are used in their corn.

When a farmer that farmed the land close to our house switched to a "new better GMO corn" my brother broke out in these horrible hives. The Dr. said he did not know what caused it, but we looked up his allergy and found that there had been some studies by other Dr. s that found direct links to his specific allergy and GMO plants. Also the first Dr. said he would always have to be on the medication. Nevertheless a couple weeks after the corn was gone so were the hives. He has never had to use the meds since.

I started out a long time ago on the side of "so what" to GMO plants.  Not so much anymore.  One of the things that changed my mind is some informaion about lectins--small nasty molecules that most plants produce to protect themselves.  They are toxic to most that would eat the plant.  Also, it turns out, some people are more sensitive to some lectins than to others.  Wheat and soy are the ones that cause the most problems but legumes, nightshades and lotsa others cause lotsa problems.  If you think you're not sensitive to wheat and soy just try eliminating for two weeks and see what happens...but...

In GMO-ing they transfer genetic material that contains lectins from one tyo plant and it ends up in another.  So if (and I think they did) they use genetic lectins from tomatoes in something else to provide some supposed benefit, anyone sensitive to tomatoes will now have the same reactiont o the GMO where it shows up but nobody told you!!!

Sigh.

One of the big things the use for genetic material in the plants is bacteria.

Does anyone get organic gardening magazine?  They have sort of a from, hybrids to modified to GM etc...makes sense.
