If you and your class want to engage in a discussion about sustainability, this is the Google Doc for you! I teach a sustainability unit to my students, and this is how I kickstart it. I post this document on Google Classroom and let my students get reading.
The link posted above will take you to a "VIEW ONLY" file. Under "FILE", select "MAKE A COPY" and save it to your drive.
The PDF version is also attached if you prefer to use that one.
I hope you enjoy!
