Hello, everybody! As we can see ,we are facing many problems about our environment. Many trees are being cut down to build houses. Waste water is being poured into the rivers or seas.Carbon dioxide is also being discharged into the air around us.All of these are harmful to us so we should take immediate measures to prevent these happening again. First I think we should educate those who are cutting trees without limit. Second we should plant more trees to reduce the amout of carbon dioxide .Finally we should appeal to those factories not to pour waste water into the rivers or seas .Only in this way can we protect our environment .
