I am still surprised at how many folks still haven't seen "An Inconvenient Truth". Even now that it has been released on DVD. Either people cannot or won’t buy the DVD, but are still interested in seeing the movie.
So, Play It Forward. Make another step to help out the environment and another person. Buy the DVD and view it yourself, if you haven't yet, then share it with someone else. Give your copy of the DVD to someone you know who would watch it, with a note to see it, then share the DVD with someone else. Ask them to also include a note for the next person to do the same thing.
While talking to my sister about this, I came up with another idea for fellow coworkers. It may be a bit harder to pass it off like that at work, when there are so many that may be interested in viewing it, so you can make "An Inconvenient Truth" Library. Have your copy of your DVD in a folder with a list of people who wish to see the movie, who have signed it out for viewing-to be returned in a timely fashion for the next person to be able to watch it and return it, crossing of their name for the next one.
Play it forward, An Inconvenient Truth.
