I'm an 8th grader from Washington State who has been working on a project concerning paperless schools. In our research we found a website that equated a ream - 500 pages of paper - to 6% of a tree.
From this number we calculated that our school of 220 students uses 45 trees worth of paper per school year, and we have been taking steps to inform our classmates about that.
Thanks for your research; you've got a whole lot of trees out there in Washington State to take care of! Keep up the good work!
