  1. 1. THE MEDITERRANEAN SEA <ul><li>People who live in the Mediterranean Sea have common characteristics like similar cultures, customs, religion and beliefs. </li></ul><ul><li>The sea unites these countries in terms of transport, fishing and commerce. </li></ul>

  6. 6. What is soil erosion? It is the removal of soil by the action of water or wind, compounded by poor agricultural practices, deforestation, overgrazing and desertification

  14. 15. Preventing Soil Compaction <ul><li>Confine animals </li></ul><ul><li>Make hay </li></ul><ul><li>Reduce stock </li></ul><ul><li>Pave camps and tracks </li></ul><ul><li>Work soil when dry </li></ul>
  15. 16. Importance of Soil <ul><li>For the livelihood of plants, animals and humans </li></ul><ul><li>To sustain healthy plant growth </li></ul><ul><li>For the agriculture </li></ul><ul><li>To protect vital natural resources </li></ul>
  16. 17. How can we solve the problem? <ul><li>Sustain or improve crop yields </li></ul><ul><li>Reduce drainage costs </li></ul><ul><li>Retain nutrients and chemicals where applied </li></ul><ul><li>Reduce hazards when working on eroding soil </li></ul><ul><li>Help improve water quality </li></ul><ul><li>Contour ploughing </li></ul><ul><li>Strip farming </li></ul><ul><li>Terracing slopes </li></ul>
  17. 18. Everyone should be sensitised to save our planet. It is in our hands.
