1. I think organic agriculture is struggling to make a comeback in time to help save the world. If their public relations are any good they'll be offering their product as an alternative that will allow people to be healthier than that provided in over processed sugar and salt and plastic.
2. excessive tillage is not part of an organic farming practise. How could it be, by definition organic strives to improve the earths potential for production.
3. I expect the agri-food conglomerates will try to move into organic and sustainable food production and not even know enough to do it properly. All the more reason to put the brakes on them now.
This is from the Canadian organic standards, I guess it is the rule that producers, consumers, and government have agreed should cover the contamination of organic produce by gm pollution.
"a. all materials and products produced from genetic engineering as these are not compatible with the principles of organic production (growing, preparing and selling) and therefore are not accepted under this standard"
It seems pretty straight forward, easy to understand, and possible within the factors controllable by the farmer. This is the point where the bioengineering companies can step up to the plate and say " Yes we are making billions selling our accursed products around the world, but to show our hearts are in the right place we will require farmers growing our gmied crops to leave border strips of non GM crops so that these people who are actually trying to do something good for the planet can have a chance." I don't even care if they snigger when they get to that last part. So long as they do it.
As to engaging in meaningful discussion perhaps it is just that the agrifood multinationals are so involved in grubing for shickels that it isn't possible to have a meaningful dialogue with them or their public relations people.
