A Blade of Grass 

       Using the rays of the sun as its source

             Of energy, grass synthesizes

      Carbon dioxide, water and minerals

              To promote green growth.

   In the process, it takes pollutants from the air,

              Filters out dust particles,

         And gives off oxygen in return.

          In fact, actively growing grass

        On a 50 by 50 foot plot releases

     Enough oxygen to meet the needs of a

            Family of four, day by day

     The world need more such greenery.
