I don't think you know a goddamned thig about modern agriculture. In the West and the industrialized East, farmers haven't produced their own seed for more than a century--except, of course, for those farmers who specialize in prducing seed. Whether you're going out to plant a vegetable garden behind your house, of seeding large fields on a commercially viable farm, you buy your seed. Before Monsanto, other companies filled that market niche, and neither they nor Monsanto produce the products they sell--farmers do. As for crops which produce sterile seed, i seriously doubt that you can come up with any evidence that Monsanto does that with an eye to increasing their profits. Once again, everyone buys their seed every year. With genetically modified crops, it wouldn't surprise me to learn that the product is sterile for the purposes of re-planting, so i suspect that would just be a by--product of the use of GM crops.
GM crops are not necessarily the product of some evil corporation's witches cauldron, either. Golden rice
has been produced from the modification of an ordinary rice variety in order to supply beta-carotene in the end product. From the linked article:
Golden rice is a variety of Oryza sativa rice produced through genetic engineering to biosynthesize beta-carotene, a precursor of vitamin A, in the edible parts of rice. The research was conducted with the goal of producing a fortified food to be grown and consumed in areas with a shortage of dietary vitamin A, a deficiency which is estimated to kill 670,000 children under 5 each year.
Note that the lunatic fringe of the environmental movement and the anti-globalization movement are loudly opposed the planting of golden rice. I guess we gotta let those half a million children a year die so as not to offend the sensibilities of the extremist, university activist crowd.
I see you have no comment on the image i posted calling on people to buy their food locally. If you were to begin a process of replanting from your own harvest, you'd soon have einkorn or emmer rather than wheat, something like teosinte rather than corn, and rye grass rather than rye. If you really want to live the good life as your ancestors did, why don't you build yourself a boat and go out and kill a f*cking whale?
