good ladies and gentlemen! my name is kim seung-eun.today i am very excited to stand here to tell you a little bit about the poor situation of global environment.
for a long time,people have exploited mineral resources for developing industry. the wide use of mineral resources causes a lot of pollutions. for example,burning oil can emit carbon dioxide and many other harmful gases.the carbon dioxide contributes to global warming which also leads to the melt of iceberg .besides mineral resources ,woodwhich is the most common material also attracted people's attention.according to the report ,in every one minute ,there are 20xx square meters of forest being destroyed.as people cutting down trees crazily, serious desertification appears ,sandstorm is getting more and more frequent,and the earth is hardly keep its temperature .look what we've done to our planet ! it's time for us to heal the world ! fortunately , more and more people have realized that the earth is sick and people are also in big trouble.thus alow-carbon life style is advocated,and in some countries the private cars are not allowed to drive ever day.
guys, as teenagers of the 21st century,as the children of the earth ,i think we have duties to save our planet.let's start from the small things in our daily life .such as planting a tree, using the public transportation , saving tap water ,stopping littering around ,… these are all easy things for us. as the old saying goes ,"drop by drop fills the tub" . if we do work together ,i believe we're gonna make a great difference toward the earth.so let's start by ourselves,start by today!that's all.thanks for your attention?
