Adele was walking in the park , she met with Katy whom shade under a shady tree .

Adele   :  “ Hi , Katy “

Katy     :  “ Hi , Adele “

Adele   :  “ What are you doing in here ? “

Katy     :  “ I am shade “

               “ Oh ya , do you know , why when we are shade under a shady tree , we can feel

                  so cool ? “

Adele   :  “ Hmmm .. I know , it is because shade trees  inhale carbondioxide (CO₂) to the

                  breathing device called stomata , to its needs in photosynthetic activity and one

                  of the photosynthetic is oxygen (O₂) that makes the cool shade under a shady

                  tree “

Katy     :  “ Oh .. that’s mean the tree very important for our live ? “

Adele   :  “ Yes , of course “

               “ Therefore we shouldn’t recklessly cut down trees but we have a lot to plants

                  trees so we can gain a lot of oxygen (O₂) .

      In addition , we also protect the earth from global warming ”

Katy      :  “ Oh ya , perhaps you’re right “

                “ Haha “

Adele    :  “ Uuuuh , I am always right “

Katy and Adele :  “ Haha "
