The importance of atmospheric resources that were outlined included:
-           carbon dioxide for photosynthesis;
-           oxygen is used by plants and animals foe respiration;
-           carbon dioxide absorbs heat to control atmospheric temperature;
-           rain water provides water for human consumption;
-           oxygen is used for combustion;
-           sunlight for drying of clothes;
            -           nitrogen for protein synthesis;
            -           carbon dioxide used for fighting fire out break;
            -           water vapour; moderate atmospheric temperature;
            -           wind for generation of electricity;
