Savory discovered that only by increasing animal numbers but changing their behaviour (with which humans had interfered) could the problem be solved and desertification be reversed. And this meant livestock over most of the world’s desertifying regions because there is nothing left.
He went on from that discovery to discover how livestock could be used as a tool to reverse desertification and thus eventually save civilization and the wildlife he loved – by using the Holistic Planned Grazing process.
