I don't support it but (1) all GMO and irradiated foods should be labeled as such and (2) patented seeds only retain protection on the farm that uses them. If the wind blows pollen from a GMO crop to an adjacent site and causes that crop to become hybridized, that crop belongs to the farmer of the contaminated field. In addition, any seed from that crop belongs to the farmer. However, the farmer whose crop is cross pollinated now needs to sell his product as being a GMO product. That farmer may also be entitled to sue the other farmer for damages.
