Yes. Really. If they didn't they would not survive long.
Really? Virtually all plants produce their own pesticides? Really?

DDT is not produced by GMOs but it is classified as moderately toxic to humans so exposure to too much of it is probably not a good idea.
Scientists also claimed DDT was safe

All widely cultivated bananas today descend from the two wild bananas Musa acuminata and Musa balbisiana. While the original wild bananas contained large seeds, diploid or polyploid cultivars (some being hybrids) with tiny seeds are preferred for human raw fruit consumption.[57] These are propagated asexually from offshoots. The plant is allowed to produce two shoots at a time; a larger one for immediate fruiting and a smaller "sucker" or "follower" to produce fruit in 6–8 months. The life of a banana plantation is 25 years or longer, during which time the individual stools or planting sites may move slightly from their original positions as lateral rhizome formation dictates

Asexual reproduction is a mode of reproduction by which offspring arise from a single parent, and inherit the genes of that parent only; it is reproduction which almost always does not involve meiosis, ploidy reduction, or fertilization. The offspring will be exact genetic copies of the parent
Asexual Reproduction
Cloning—In biology and agriculture, any organism whose genetic information is identical to that of a parent organism from which it was created; natural reproductive processes producing clones include parthenogenesis and apomixis

Bananas are all genetic clones, but you enjoy them probably on a regular basis. They were made so you didn't have to worry about nasty banana seeds in your fruit, but no one ever complains about the bananas.
As my source said, research is inconclusive. Maybe 3/4 of the corn in the US is roundup-ready and I eat my share of that, and it hasn't killed me yet, so it can't be too toxic. But I do wonder about the long term effects when I see studies like this one:

Something to be included for consideration is, is there any thing in particular about GMO crops that would imply that they pose a health risk.
It could be that long term human exposure will have no ill effects as models indicate should be the case, but so far there are no humans who have consumed roundup for a lifetime at these levels. Let's hope the models are accurate, but they aren't always accurate. The surfactants in roundup may actually have greater toxicity than the glyphosate.
Our studies show that glyphosate acts as a disruptor of mammalian cytochrome P450 aromatase activity from concentrations 100 times lower than the recommended use in agriculture; this is noticeable on human placental cells after only 18 hr, and it can also affect aromatase gene expression. It also partially disrupts the ubiquitous reductase activity but at higher concentrations. Its effects are allowed and amplified by at least 0.02% of the adjuvants present in Roundup, known to facilitate cell penetration, and this should be carefully taken into account in pesticide evaluation. The dilution of glyphosate in Roundup formulation may multiply its endocrine effect. Roundup may be thus considered as a potential endocrine disruptor. Moreover, at higher doses still below the classical agricultural dilutions, its toxicity on placental cells could induce some reproduction problems.

You have one of two varieties that are cultivated. Each plant is then an exact copy of the parent, if you read what I posted completely, these plants reproduce asexually this was the point of each link and finally the definition of cloning.

You are also aware that GMO "Biotech" is a large portion of selective breeding right? They plant test crops, blast them with pesticides select those that survive the apocalypse then investigate the genomes in those plants that provided the resistance. They then take a test crop and expose them to long term pesticide levels that will cause later harm, and select offspring that are developing a resistance.
They then begin the " Bio-tech" as you call it, and take the genomes from all the choice plants, and produce a sequence they feel is best suited for the application. They then have as many seeds as they want with the exact properties desirable to resist herbicides that would otherwise destroy a crop. For instance Glyphosate(round up), round up kills almost anything green. How ever through selective breeding and their genetics program they have products that do not die in the presence of Glyphosate.
He cited thoroughbred horses, show dogs and crops as examples of genetically engineered plants and animals dating back centuries. "When Farmer Jones did it in his cornfield to try to get a better crop, it didn't bother people," Schaffner said. "When scientist Jones did the same thing in a much more sophisticated fashion in a lab, that does bother people."
Interesting experiment, examining the effect of Roundup and/vs glyphosate. In vitro studies are important but they sort of ignore how it is survives the digestive and metabolic processes. This would have to be considered as well. The experiment exposed cells to "straight" (2%, the concentration used in the field) Roundup and glyphosate.
But I do wonder about the long term effects when I see studies like this one:
Can you provide some more information on this?
For example using roundup resistant crops uses more chemicals than traditional crops
This incident will have some effect. No doubt. There are places which will not accept GMO crops in any form.
How about the effects on local economies like the Pacific Northwest’s wheat export?
It's mostly because it is a problematic thing to do. The ingredients for processed foods come from a variety of sources. In order to "certify" that a particular loaf of bread or bag of tortillas is non-GMO can become very difficult. This additional effort will, undoubtedly, add to costs (for the manufacturer as well as the consumer). Don't misunderstand, I am not against labeling. But I do understand the difficulties involved.
If this is true why not flaunt it and be proud of their accomplishments? Instead large amounts of money have been spent campaigning against labeling measures in several states as well as the Federal Government.
You are confusing cloning with hybridization while commenting about genetic modification. The three are not the same.
Bananas are all genetic clones

Modifying foods to grow disease and drought resistant doesn’t sound like a bad thing to me or being able to grow crops in otherwise unsuitable soil sounds good to me.
If they are like poison as some sites say where is the evidence to back it up. This is pretty new topic to me. I have seen several posts throughout ATS in the past berating Monsanto but until today I have never bothered to look into it without any success at finding substance.
If someone would be kind enough to post some links to what convinced you on the evils of this new subject matter I would appreciate it.

The situation, according to a report published last Friday in the peer-reviewed journal Environmental Sciences Europe, has driven growers to use larger quantities of Roundup, more often and in conjunction with a broader arsenal of other weed-killing chemicals.

'Agent Orange Corn' Debate Rages As Dow Seeks Approval Of New Genetically Modified Seed
This is why I strongly feel we need a federal GMO labeling requirement. If GMOs are labeled starting from their source then it will not be difficult to label manufactured products. I understand there will be difficulties but I think the benefits will far outweigh the costs.

It's evident that they did not destroy all the seeds. I doubt if this is the only field either. When you create a monster, you are responsible to get rid of the monster. Another thing, I think there was something found wrong with the wheat, I don't think that it was abandoned just because of people's skepticism, they didn't abandon the corn or Soy did they?
