ORIGINAL: samboct HI Firm Hi Sam. Thanks for the well-thought out post. quote:
ORIGINAL: samboct I used to have your viewpoint on genetic modifications done in the lab these days- that it's nothing more than speeding up the previous methods of biology from selective breeding. However, a biologist pointed out that we can mix in genes from organisms that couldn't mix before. Viruses can insert themselves into organisms, but we're creating chimeras. Imagine a dog/mouse chimera-even if you used dog semen into a mouse, you wouldn't get anything. But now we can do such chimeras at the genetic level, so there is a question of safety, we haven't got millions of years of evolution blocking something that might be a no/no. It is still nothing more than the speeding up of previous methods. We can more effectively, and quickly add different "software packages" of DNA into other organisms, or even code new ones ... but the "natural" method of either inducing, or breeding mutations is essentially the same thing, only less certain, and more time-consuming. And cross-genetic transfers do occur in nature as well. From the wikipedia link that's been given several times: However, other methods exploit natural forms of gene transfer, such as the ability of Agrobacterium to transfer genetic material to plants, or the ability of lentiviruses to transfer genes to animal cells. One of my earlier posts mentioned the Lager beer yeast: The resulting hybrid, representing a marriage of species as evolutionarily separate as humans and chickens, would give us lager, the clear, cold-fermented beer first brewed by 16th century Bavarians. As for safety, that should always be a consideration. However, from the same Wikipedia article: For a genetically modified organism to be approved for release it is assessed by the Animal and Plant Health Inspection Service (APHIS) agency within the United States Department of Agriculture (USDA), the Food and Drug Administration (FDA) and the Environmental Protection Agency (EPA). The USDA evaluated the plants potential to become weeds, the FDA reviewed plants that could enter or alter the food supply and the EPA regulated the genetically modified plants with pesticide properties. Most developed genetically modified plants are reviewed by at least two of the agencies, with many subject to all three. A more in-depth discussion can include a lot more, such as the "freeze" in research self-imposed a couple of decades ago by some other researchers. quote:
ORIGINAL: samboct Overall though, it's not a threat that I worry about too much- but there is a different problem that's a concern. We're going increasingly to monocultures for our food supply, and monocultures have a problem that when an invading species figures out how to take them out, well, there's going to be nothing left to occupy their niche. Let's face it, these monoculture crops are one big inviting food source for a variety of organisms such as fungus, viruses, bacteria etc. In the bad old days, if one strain of wheat got wiped out by a blight, well, you planted something else. But Monsanto is trying to make sure that there really is nothing else- that everything out there is owned by them. I find this monoculture reliance problematic- especially with global climate change altering the environment. Seems to me that if you've got a half dozen strains of wheat, if the temperature does something funky- well, you've got a lot better chance of at least one of them surviving rather than a single strain. I agree that monocultures are a danger. So is starving, however. There are others who are concerned. Read about the Svalbard Global Seed Vault and the International Treaty on Plant Genetic Resources for Food and Agriculture. I'm not sure that a short-term disaster couldn't result in massive starvation, but in the long-term the things such as the Vault and the Treaty point to some pretty good planning on mankind's part, I think. quote:
ORIGINAL: samboct I don't have a problem with labeling GMO stuff in theory, but in practice, I think the horse has already left the barn. However, I think that consumers do have a right to know what they're purchasing, especially if they want to vote with their dollars and buy something else. It's a democracy- people get to make their own choices- its not for us, even if we have a snazzy education, to say that we know what's good for you. People can waste their money buying vitamins too as well as a wide variety of plant extracts of dubious safety and utility. PS_ I watched a few minutes of that "documentary" against Monsanto. Lots of errors- PCBs were never the jewel of their business, they were a diversified mfg. And most people thought that those oils were benign- some folks used to use them as a lotion. A lot of the compounds they make sound scary especially if you mispronounce aspartame, but they're really not. Most compounds aren't toxic. I'm not sure that Monsanto is much worse than a company such as GE, but I haven't looked that closely. You have identified what I consider a problem with some of other posters' position: they are attacking the technology in order to attack the corporations or the capitalist system. They may not realize that they are being anti-scientific, and supporting hunger and possible famine, but often times they either do not understand the real consequences of the "solutions" they seek, or they are so ideologically driven that they do not care. "Labeling" sounds ah-so-prudent, but in reality what they wish to do is isolate and then scapegoat the technology. Which is why I support labeling of "organic" products instead, if they wish to label something. In other words, their "labeling" position is nothing more than a method to make demonizing easier and more effective, not any real attempt to give "choice and freedom" to people. Firm
