One environmental group gave out workbooks made from recycled paper bound with cute ribbons and some cool peach tea to students who carried a portable water bottle at the last Gashin Daedong festival. I happened to have an empty drink bottle, so I could fill some peach tea into my bottle and receive the workbook. The sweet tea and the lovely workbook delighted me, but I didn’t know how much I could contribute to protect the environment just by using scratch paper and my own cup instead of paper cups.
 It takes 20 years for 20 trees grown enough to make a ton ofpaper cups which we dump after using only one time. It takes 20 years for the paper cups treated with chemicals to be decomposed. 1,200 trees have to be felled for the volume of paper which people all around world use in a day. Additionally, only one person consumes 237 trees for paper products in a lifetime. A forest as big as a football field has been cut down every 2 seconds since the method to produce paper from trees was found in the mid-nineteenth century. Now, only about 20% of the virgin forests in the world are left. The more people waste paper, the more forests are destroyed.
 To make paper, people began to create artificial forests of Eucalyptus. The Eucalyptus trees were in the limelight because the trees can be harvested within 4 to 10 years. The problem is that roots of Eucalyptus trees grow 30 meters below the surface. The long root absorbs underground water and rainwater, so it ruins the surrounding forests.
 If the entire nation saves a sheet of A4 paper every day, 4,800 trees wouldn’t need to be cut down. People squander very precious things not just pieces of paper. They should reduce the amount used. People commonly think protecting the environment is a very troublesome duty, but several simple everyday habits like using one’s own cup, recycling scrap paper or carrying a handkerchief surely help to make an important achievement.
