Your food isn’t. Monsanto came up with it and in the beginning, had complete control but that is no longer the case. Everyone jumped in and there are 100s of companies with GMO seeds.
Unless you have your own well, water is controlled by government though and in most places government decides if you can have a well.
True about the water, now the air, and the food. They can even control if, when and what you plant. You need a license to hunt or fish, and limits on how much you can harvest. Face it, modern man is not as free as the peasants in Victorian England.
