If they drive the price too high for genetically altered seed, the farmers can revert to simply hybrid or even back to heritage. That would be an eye-opener, wouldn't it?
Save seed and plant it. Every farmer should do that with 10 to 20 acres every year, anyway, just to keep it viable. Yield would be smaller, but satisfaction would be greater, and cost would be less.
That would be a thought; but unfortunately, premise registration and seed tagging is being introduced in the states also.
It is against the law to keep your crop and replant it. The seed companies will sue you. My neighbor just had to pay $80,000 after losing.
