Do you have a credible source that backs this up? My reasoning is based on the fact that native milkweed has been in a major decline over the last two decades, and many studies have linked this decline to increased Round-Up (glyphosate) use associated with the expansion of GM crops. Milkweed is needed by the Monarch Butterfly for reproduction, and they are in a steep decline as well. https://www.ewg.org/agmag/2016/03/gmo-linked-herbicide-may-doom-monarch-butterflies#.WoWpeujwa71 Quote The explosion in glyphosate use has killed off the milkweed plants where monarchs lay their eggs. The study said the dwindling monarch population is “predominantly attributed” to the loss of milkweed breeding habitat, especially in the U.S. "Declines in milkweed abundance are well documented and highly correlated with the adoption of herbicide-tolerant genetically modified corn and soybeans, which now constitute 89 percent and 94 percent of these crops, respectively, in the U.S.,” Here's an NPR article that contends that GM crops have led to less insecticide use, but have likely led to more herbicide use: https://www.npr.org/sections/thesalt/2016/09/01/492091546/how-gmos-cut-the-use-of-pesticides-and-perhaps-boosted-them-again Link to comment

GMOs are all around us, and they're not (necessarily) bad. No, no, no. GMO's are NOT the same as breeding. GMO's have been modified using genetic engineering. Wikipedia: Quote The term GMO is very close to the technical legal term, 'living modified organism', defined in the Cartagena Protocol on Biosafety, which regulates international trade in living GMOs (specifically, "any living organism that possesses a novel combination of genetic material obtained through the use of modern biotechnology"). ... The first genetically modified mouse was created in 1974, and the first plant was produced in 1983. GMO's are typically combinations of genes from different species.

funhusker Posted February 15, 2018 Share Posted February 15, 2018 (edited) To bring the GMO topic back to the discussion: the question was "Are GMO's safe to eat".

(being intentionally facetious here ) Of course there are multiple angles to each of these topics, and hopefully they are approached using sound science. This thread was to discuss how people deny science even when there is consensus. There is consensus GMO's are safe to eat, there is definitely NOT a consensus if GMO's make our world better. 1 Link to comment

Sorry about that I fixed it, but here is the Pew article again: http://www.pewinternet.org/2017/12/08/mixed-messages-about-public-trust-in-science/ Here were their poll numbers: MMR Vaccine: 55% Almost All 28% More than Half 15% Half or less Climate Change: 27% Almost All 35% More than Half 35% Half or less GMO Safety: 14% Almost All 28% More than Half 53% Half or less Link to comment

I'm not quoting wikipedia as gospel, but if you go to the page for GMO's it says, "A genetically modified organism (GMO) is any organism whose genetic material has been altered using genetic engineering techniques" If you click on 'genetic engineering techniques', and go to the history section, it says, "Humans have altered the genomes of species for thousands of years through selective breeding, or artificial selection[19]:1[20]:1 as contrasted with natural selection, and more recently through mutagenesis. Genetic engineering as the direct manipulation of DNA by humans outside breeding and mutations has only existed since the 1970s." All I'm saying is that the way we created dogs and changed fruits through selection pressures and artificially forced selection is a sort of genetic engineering. Link to comment

It's an example of one being developed to kill a certain weed. The argument is, do we want that weed killed at the rate it's being killed. Round-up is one of the safest and less damaging chemicals farmers have used in decades. It really is amazing how much safer it is to people and the environment compared to other herbicides. But..it's used so often as a boogie man in this debate. Link to comment
Moiraine Posted February 15, 2018 Share Posted February 15, 2018 (edited) knapp/Landord/whoever, in modern times, when people (and more specifically, scientists) use "GMO" they are not talking about selective breeding. GMO is synonymous with modifying the genetic makeup. No one who researches the benefits/safety/possible dangers of GMOs is looking into cross-pollination, or things like that. They're talking about gene modification, splicing, etc. That's what it is by definition. We're not talking about mixing peanuts with grapes by planting them next to each other or asking bees to have sex between a peanut seed and a grape seed in order to make the perfect sandwich. I'm assuming you both know this and are posting these things for the fun of it. Edited February 15, 2018 by Moiraine 1 Link to comment
Moiraine Posted February 15, 2018 Share Posted February 15, 2018 An example: they can and have introduced animal DNA into plants. They can also turn specific genes off and on. There is a professor at UNL doing this. I believe they're looking into creating fuel from algae. Basically, a GMO is something that cannot be created through breeding. Link to comment
