Submit your papers and other homework via email. If you have laptop then use it. Instructors can put all assignments, lecture notes and handouts online using a blog or website to which all students have access.  They can also set up a dropbox or other collection tool to which students can submit papers and homework. You can download software that will help save paper by removing wasteful content when printing from the Web and reformatting documents to print more efficiently.  Well-reviewed ones include FinePrint, PrintEco, & Printfriendly. Adjust your copier's settings so that the machine prints on both sides of the paper when you're making copies of multi-page documents. Align discarded printer paper so all the blank sides are facing one direction, 3-hole punch it and send it through the printer again for a second use.
