The main problem with GM crops is the way courts and the law have dealt with them as intellectual property to date. If a farmer plants non-GM crops in a field across the road from GM crops owned by Monsanto, and there is cross-pollinisation, then Monsanto can sue to confiscate or destroy the non-GM planting farmer’s crops.
GM itself isn’t the problem - Monsanto is.
Can you cite specific a case in law where this happened? Was it appealed? where?
