the organic food

I would like to learn about food. I spent this fall break at an organic farm which raises many animals and grows vegetables. The animals are raised in very large spaces surrounded by nature, so they have no stress. The vegetables are grown without pesticides. I was impressed by the taste of the food, and I felt really safe because I knew where it came from.  Although most of the food market here is based in industrial farms, I want to support local and small organic farms. Therefore I want to learn about this topic.
