EVEN THE BOTTOM OF THE RIVER WAS FULL OF RUBBISH. THERE WERE NO MORE FISH FOR FISHERMEN TO CATCH. WHAT CAUSED THE PROBLEM?PEOPLE ARE THROWING LITTER INTO THE RIVER.FACTORIES ARE PUTTING RUBBISH INTO THE RIVER.HOW SHOULD THE PROBLEM BE SOLVED?EVERYONE SHOULD HELP TO CLEAN UP THE RIVER.THE RIVER WAS DIRTY. EVEN THE BOTTOM OF THE RIVER WAS FULL OF RUBBISH.BUT IT USED TO BE SO CLEAN! YES, BUT PEOPLE ARE THROWING LITTER INTO THE RIVER.EVERYONE IN THIS TOWN SHOULD PLAY A PART IN CLEANING IT UP!THE AIR IS BADLY POLLUTED BECAUSE THERE ARE MORE CARS ON THE ROAD THESE DAYS.FACTORIES THAT BURN COAL ALSO POLLUTE THE AIR WITH A LOT OF BLACK SMOKE.THERE IS ALSO TOO MUCH RUBBISH AND WASTE. PEOPLE ARE THROWING AWAY THINGS EVERY DAY.PEOPLE ARE ALSO LITTERING IN PUBLIC PLACES LIKE PARKS. THIS IS TURNING BEAUTIFUL PLACES INTO UGLY ONES.THE AIR HAS BECOME REALLY POLLUTED AROUND HERE.IM GETTING VERY WORRIED.YES, I USED TO BE ABLE TO SEE STARS IN THE SKY. THE PROBLEM IS THAT WHERE SHARK FIN SOUP IS POPULAR?IT IS VERY POPULAR IN SOUTHERN CHINA.NUMBER OF SHARKS CAUGHT AND TRADED EVERY YEAR IS AROUND 70 MILLION.HOW MUCH THE NUMBERS OF SOME KINDS OF SHARKS HAVE FALLEN IN THE LAST 20 TO 30 YEARS?OVER 90 PERCENT. TWO ENVIRONMENTAL GROUPS AGAINST “FINNING” ARE WILDAID AND THE WWF.MANY PEOPLE DO NOT REALIZE THEY ARE KILLING A WHOLE SHARK WHEN THEY ENJOY A BOWL OF SHARK FIN SOUP.SHARKS ARE AT THE TOP OF THE FOOD CHAIN, SO IF THEIR NUMBERS DROP,THE OCEANS ECOSYSTEM WILL BE IN DANGER. MANY THINK THAT SHARKS ARE TOO STRONG TO BE ENDANGERED, BUT THEY ARE WRONG. ALTHOUGH THERE ARE NO SCIENTIFIC STUDIES TO SUPPORT THIS,A LOT OF PEOPLE BELIEVE THAT SHARK FINS ARE GOOD FOR HEALTH.SHARKS MAY DISAPPEAR ONE DAY IF WE DO NOT DO SOMETHING TO STOP THE SALE OF SHARK FINS.WERE TRYING TO SAVE THE EARTH.THE RIVER USED TO BE SO CLEAN.THE AIR IS BADLY POLLUTED.NO SCIENTIFIC STUDIES HAVE SHOWN THAT SHARK FINS ARE GOOD FOR HEALTH.WE SHOULD HELP SAVE THE SHARKS. HAVE YOU EVER TAKEN PART IN AN ENVIRONMENTAL PROJECT?YES, I HAVE. I HELPED WITH A CLEAN-UP DAY LAST YEAR.

I GUESS EVERYONE IN THIS CITY IS TRYING TO IMPROVE THE ENVIRONMENT.YES, WE CANT AFFORD TO WAIT ANY LONGER TO TAKE ACTION!PEOPLE MAY THINK THAT BIG THINGS HAVE TO BE DONE TO SAVE THE EARTH. MANY FORGET THAT SAVING THE EARTH BEGINS WITH SMALL THINGS. FOR EXAMPLE, YOU SHOULD SAVE ELECTRICITY BY TURNING OFF THE LIGHTS WHEN YOU LEAVE A ROOM. YOU CAN ALSO USE REUSABLE BAGS INSTEAD OF PLASTIC BAGS.I THINK ITS A GREAT IDEA THAT YOU NOW HAVE TO PAY FOR PLASTIC BAGS IN SOME STORES. AND INSTEAD OF DRIVING TO SCHOOL OR WORK, YOU SHOULD RIDE YOUR BIKE OR WALK.IF ITS FAR, YOU CAN TAKE THE BUS. ALL THESE SMALL THINGS CAN ADDUP AND BECOME BIG THINGS THAT CAN IMPROVE THE ENVIRONMENT. LETS TAKE ACTION NOW! I THINK THAT EVERYONE SHOULD USE PUBLIC TRANSPORTATION.I DISAGREE. ITS DIFFICULT FOR PARENTS WITH YOUNG CHILDREN TO USE PUBLIC TRANSPORTATIONSTOP RIDING IN CARS.RECYCLE BOOKS AND PAPER.TURN OFF THE LIGHTS WHEN YOU LEAVE A ROOM.TURN OFF THE SHOWER WHILE YOU ARE WASHING YOUR HAIR.DONT USE PAPER NAPKINS.RECYCLING PAPER IS REALLY EASY.I AGREE. BUT ITS HARD TO STOP RIDING IN CARS.WE REALLY SHOULDNT USE PAPER NAPKINS, YOU KNOW.I KNOW. I STOPPED USING THEM LAST YEAR.AMY HAYES LIVES IN THE UK. MANY OF THE OLD BUILDINGS IN HER NEIGHBORHOOD WERE PULLED DOWN.ALL THE RUBBISH AND OLD THINGS IN AMYS NEIGHBORHOOD WERE THEN PUT TO GOOD USE WHEN AMY BUILT HER HOUSE.AMY IS VERY CREATIVE. SHE BUILT HER FRONT GATE OUT OF ROCKS AND OLD GLASS BOTTLES. SHE PUT AN OLD BOAT ON TOP OF HER HOUSE. JESSICA WONG SELLS HER BAGS IN A SMALL SHOP, BUT SHE HAS ALSO SET UP AN ONLINE BUSINESS TO SELL THEM. THOUGH JESSICAS BAGS ARE MADE FROM OLD CLOTHES, HER BAGS ARE KNOWN FOR BEING CUTE AND USEFUL.WANG TAO NOT ONLY MAKES LARGE PIECES OF MENTAL ART THAT LOOK LIKE ANIMALS OR HUMANS, BUT ALSO MAKES SMALLER PIECES FOR THE HOME.THE RIVER USED TO BE SO CLEAN.WE HAVE SEEN MANY CHANGES IN THE ENVIRONMENT. PEOPLE SHOULD TAKE PUBLIC TRANSPORTATION MORE.THE RIVER IS POLLUTED BY FACTORIES. THE AIR POLLUTION IS GETTING WORSE AND WORSE.KINDS OF POLLUTION SUCH AS WATER POLLUTION, LAND POLLUTION, NOISE POLLUTION AND AIR POLLUTION. THINK ABOUT WAYS TO CUT DOWN SO MUCH POLLUTION.GOOD HABITS ACHIEVE BEAUTIFUL LIFE.TRY TO BE OUR BEST.
