Global　Shortage　of　Fresh　Water

　　People　often　think　that　water　will　never　be　used　up.　There　is　plenty　of　water，　such　as　rain，　water　from　the　rivers　and　wells.　It　seems　as　if　water　is　always　available　around　us　and　we　never　have　to　worry　about　water　shortage.

　　In　fact　water　is　rather　limited　on　the　earth.　With　the　rapid　increase　of　population　and　fast　development　of　industries，　water　is　more　needed　than　before.　At　the　same　time，　a　large　amount　of　water　has　been　polluted　and　wasted　every　day.　Some　big　cities　in　China　are　facing　the　problem　of　water　shortage　already.　There，　water　supply　is　controlled　and　industry　has　been　restrained.

　　What　should　we　do　about　the　water　shortage？　I　think，　first，　the　people　should　be　made　aware　of　the　real　situation　about　the　water.　Everyone　should　consciously　save　on　water　and　certain　law　should　be　made　that　no　water　will　be　polluted.　We　have　to　protect　the　existing　water　resources　and　develop　new　ones.　In　this　way　I　believe　that　our　cities　will　not　be　thirsty　for　water　in　the　future.
