In reply to the discussion: Altered Genes, Twisted Truth: How the Venture to Genetically Engineer Our Food Has Subverted Science [View all]PufPuf23
(8,776 posts)Caveat: Gene splicing also know as genetic modification is a valid technology. However, the science is relatively new.
The technique has allowed a revolution in the medical, agriculture, research science, and other fields.
Corporate supporters understate the direct risks and overstate the benefits of genetic modification of food and material crops on a landscape scale. . The external risks to soil, genetic diversity, human society, etc. are understated or ignored. There are large short term financial rewards for manufacturers of gmo strains and corporate agriculture.
My perception is that there are shills at DU and elsewhere that seek to foster the idea that the questions attendant to corporate agriculture based upon gmos is a closed question when this is not in fact true.
Plant breeding
wiki: https://en.wikipedia.org/wiki/Plant_breeding
Plant breeding is the art and science of changing the traits of plants in order to produce desired characteristics.[1] Plant breeding can be accomplished through many different techniques ranging from simply selecting plants with desirable characteristics for propagation, to more complex molecular techniques (see cultigen and cultivar).
Plant breeding has been practiced for thousands of years, since near the beginning of human civilization. It is practiced worldwide by individuals such as gardeners and farmers, or by professional plant breeders employed by organizations such as government institutions, universities, crop-specific industry associations or research centers.
International development agencies believe that breeding new crops is important for ensuring food security by developing new varieties that are higher-yielding, resistant to pests and diseases, drought-resistant or regionally adapted to different environments and growing conditions.
Genetic engineering (gene modification)
wiki: https://en.wikipedia.org/wiki/Genetic_engineering
Genetic engineering, also called genetic modification, is the direct manipulation of an organism's genome using biotechnology. It is a set of technologies used to change the genetic makeup of cells, including the transfer of genes within and across species boundaries to produce improved or novel organisms. New DNA may be inserted in the host genome by first isolating and copying the genetic material of interest using molecular cloning methods to generate a DNA sequence, or by synthesizing the DNA, and then inserting this construct into the host organism. Genes may be removed, or "knocked out", using a nuclease. Gene targeting is a different technique that uses homologous recombination to change an endogenous gene, and can be used to delete a gene, remove exons, add a gene, or introduce point mutations.
An organism that is generated through genetic engineering is considered to be a genetically modified organism (GMO). The first GMOs were bacteria generated in 1973 and GM mice in 1974. Insulin-producing bacteria were commercialized in 1982 and genetically modified food has been sold since 1994. GloFish, the first GMO designed as a pet, was first sold in the United States in December 2003.[1]
Genetic engineering techniques have been applied in numerous fields including research, agriculture, industrial biotechnology, and medicine. Enzymes used in laundry detergent and medicines such as insulin and human growth hormone are now manufactured in GM cells, experimental GM cell lines and GM animals such as mice or zebrafish are being used for research purposes, and genetically modified crops have been commercialized.
