You really should look into each of your state's Sustainable Ag Society (they go by different names in each state, but if you Google Sustainable Ag and your State you should find yours)
They are a group of consumers and small farmers that have the exact concerns you do. They form a board and send out groups to raise awareness and campaign for everything you just talked about. Ours has the attention and support of several of our state senators. But they do need members.
