Monsanto which is a company that makes GE seeds and sells them to the farmers directly, they are called Roundup ready seeds, which are genetically made to withstand the roundup weed killer. They basically can plant the seed and spray roundup on the plants ad it will only kill the weeds and not the actual plant. Since this type of company has a patent on their product it is made available only for a certain time that the producer will make it available. A patent is a legal document that gives an inventor such as Monsanto the exclusive right to make and sell their product for a certain period or time. Farmers need to have permission form Monsanto to keep farming their material, if not they can’t continue their farming without it. Farmers who buy Monsato seeds can only use them for that season, year after year they have to buy new seed. If a investigator finds a farmer who is illegally using old seed they can get sued. Farmers sign an agreement with Monsanto promising to plant the seeds for only one season. This makes it hard for poor families surviving off of their farming to keep buying the Monsanto
