Foodopolies

I am doing my research paper on foodopolies which are the monopolies on our food. Monopolies are taking over food industries and changing the way are food is produced, these monopolies are using patents on their seeds and damage many farmers. One question that continues to come up is what can we do to stop these monopolies from taking over our farms and farmer? Lastly what will happen to our farms and our food if these monopolies continue running our food? Please let me know your thoughts.
