  1. This video really touched me and I feel that this information has to spread out and become a common sense! I am thinking about translating it into Estonian (subtitles maybe), so that it could be understood in my country as well. Thank you very much for sharing this! It is just what I need – to find more information and inspiration about soil!

  2. Good presentation. I support the principles but would question some of the details. We really do need to change the way we grow our food for the health of the environment and our own health. I would like to add that farmers need to make enough income so they can afford to change to a better system.
