I can't resist. . .
Well, generally I keep quiet on the really emotional topics, but I'd like to point out that saying "GMOs are bad" is something like saying "hormones (or antibiotics, or just about anything complicated) are bad". It's too complicated for the sweeping statement, in my opinion.
There are many different types of GMOs; many different gene sequences that are inserted, into many different organisms.
Three examples:
1. Pharmaceuticals
Many drugs are made using GM technology these days.
One example is Thyrogen (or Thyrotropin alfa) recombinant human thyroid stimulating hormone (TSH); it is a glycoprotein which is produced by recombinant DNA technology. Thyrotropin alfa is synthesized in a genetically modified Chinese hamster ovary cell line.
Anyone who has any recent experience with thyroid cancer knows what misery Thyrogen allows patients to avoid. I for one think this is a "very good" use of GMOs.
2. Glyphosate resistance gene
This is the "Roundup ready" gene that is inserted into Canola and soybeans. It has undeniably resulted in an in enormous increase world-wide of the use of glyphosate, as well as the evolution of many glyphosate-resistant strains of weeds, necessitating the use of other, probably nastier, herbicides. I think that this is a "very bad" GMO.
3. Bt gene
This bacterial gene has been inserted into cotton, potatoes and corn. Expression of the gene results in the death of specific insect larvae that feed on the crop. It has reduced insecticide use by a considerable amount, and has the additional benefit over conventional pesticides of killing only those insects that are feeding on the crop, not other possibly beneficial, invertebrates. While there is room for argument here, particularly with respect to the evolution of resistant insects, I’d (cautiously) say that I think the use of Bt GMOs has been generally a good thing.
I’m not trying to start a fight, but I do think there’s room for discussion on this subject that might help all of us consider aspects we hadn’t previously thought of.
Does this constitute thread-stealing? I just stuck to the subject line. . .
