I'm not educated on GM crops but I have a couple of concerns that come to mind. Does anyone know about the following possible points?
- reliance on GM companies. If a farmer only plants GM seeds, they will produce no seeds for future crops and therefore need to keep purchasing seeds from manufacturer. Call me pessimistic but it seems that the long term picture is one of rising prices and monopolisation of the market. This may sound relatively harmless but when you're talking about food sources I find it scary
- crop failures. From what I understand, GM seeds are genetically identical within crops. So if there is an out real of a crop disease, or a pest manifestation, would that mean none of the crop will survive? B/c they have the same weaknesses, strengths etc
- I also have concerns over taste & nutritional value being substituted for appearance with GM foods.

Your first point is in relation to the so-called "terminator" gene. This got masses of publicity a few years ago. Yes, it would stop farmers from saving seed from year to year. It would also however reduce the likelihood of GM crops from interbreeding with other crop, as the plant self-destructs after a single season. It's my understanding that this techology is NOT currently in use commercially but has been patented.
From my knowledge I'd say crop failure is probably just as likely with non-GM crops. Variety within crop species would have to be pretty low as we humans have genetically modified them over generations (via selective breeding) to be all the same.
It's my understanding that taste and nutrition are not affected by GM as the genes for these factors aren't the ones being manipulated.

In regards to taste there are some foods which have a different taste, some canola oils taste like fish and there is nothing like home grown tomatoes. oh wait a minute there might be, they are now genetically modifying tomatoes to put the tasty gene in.....
Nutrition wise and health wise I think the jury is still out
