Monsanto, Dupont, BASF et. al. seed manufactures exploit a court case started by General Electric when they wanted to patent bacteria to clean up oil spills. The US Patent office didn't allow patents on biological material. GE won this case...and then dropped research on the bacteria because it turned out to be horribly damaging to the environment and pretty useless as a product.
This opened the window for many other countries allowing similar patents. Seeds, which were once open and bread in many universities or by individual communities of farmers, were now a totally for-profit capitalistic institution.
Monsanto is evil. They go after farmers who have their crops infected by Monsanto products due to basic wind and cross-pollination. Once a judge rules the seeds have patented DNA, farmers have to dump all their collected seed supply.
You are spewing the official garbage line nonsense. It has nothing to do with science or the safety of GMO (which is an entirely different issue). It has to do with something that was once commons and community now being closed and for-profit for no damn good reason or benefit.
