Not necessarily - if you look at the benefits of, say, Bt crops, the farmers who would normally have walked through their fields spraying pesticides benefit much more than those who drop it from an aeroplane. For example, a "dramatic reduction in pesticide applications in Bt cotton fields has also been reported in China, and the proportion of farmers with pesticide poisoning has been reduced from 22% to 4.7%" according to this article in TRENDS in Plant Science.
The problem that happened in India was that those crops, which are very productive under industrial conditions (access to irrigation, good quality fertilizers, ect) tend to fare a lot less well in subsistance agriculture conditions, where amounts of water and quality of fertilizers (dung) may vary.
I don't really buy the monoculture argument. There are over 1000 varieties of herbicide-tolerant soybeans in the US in cultivation. To me, this is a great opportunity to preserve the diversity out there because it allows pure and sterile lines to be protected. But there's a good chance I'm confusing your argument with another common one. Forgive me if that's the case.
Yes, it was probably confusing. By monoculture I meant cultivating the same crop over a very large area of land, which allow for mechanized farming. Since India has a large supply of farm workers at low cost, they tend not to farm in this way. Indeed, industrial monoculture has already robbed many indian farmers of their jobs and sent them into city slums. I'm not sure that constitutes an improvement in their lives.
And you don't think they would benefit from Bt crops, which drastically reduce the cost of pesticides? The biggest benefits of GM crops are in the input costs; not necessarily the yield. Roundup Ready crops, regardless of what, regretfully, Monsanto claims, are not expected to increase yields.
I'm not sure what fertilizers and irrigation has to do with it.
The high yields demanded by our type of agriculture often come at the cost of a loss of resistance to difficult conditions such as poor soils and droughs. As I said, those varieties work well here but may be catastrophic for a third world country practicing familial/subsistance farming and which has very low reserves of food.
Unless you knowingly plant GM crops in violation of the contract, Monsanto will pay all the cleanup costs. I have yet to hear of an unfair case in this area. Activists often point to Percy Schmeiser, but it's quite blatantly obvious that he knowingly destroyed his own crops to plant RR crops without permission.
I'm not sure how I would explain that to a illeterate farmer of india or africa, which may already have commited suicide after being accused of such a thing because he cannot afford to defend himself.
It's possible, but that's exactly what happens with in nature with transposons and retroviruses. The effects of course depend on the specific variety. Herbicide-tolerant crops are less fit in the wild; Bt crops are more fit. Also, this is not specific to biotechnology.
Also not specific to GMOs - in fact, this has happened with hybrid celery that was causing rashes on people's hands. The probability of a single-gene insertion causing this change pales in comparison to the probability of natural hybridization causing it. Why does nobody worry when thousands of genes are introduced at once?
Yes, it does happen in nature, after all, all the tools that allow us to do this come from nature. And I'm not a believer in "natural is better than synthetic" anyways. I'm just questioning the risk-benefit ratio of it all. As I understand it, spliced-in genes tend to behave more like transposons or retroviruses than like stable genes. Is increasing the presence of such things (confering resistance to or producing toxic chemicals) in our environment a good/bad/neutral thing ? I frankly don't know.
As far as I know, the FDA, EPA, and USDA all require certain tests to be performed on GMOs, even if every ingredient is GRAS.
I'm not sure, but didn't the recent legislation lower the requirements for testing of GMOs ?
