Recently I asked some of my students why we always advertise for things that are for sale, when some of the most important things in life cannot be bought or sold. I even had them do up PSAs. Well, they did them in print-advertisement formats, but I think sometime later, I’ll show them a couple of the ads from the fightglobalwarming.com webpage. If you want to see one of them, you can click under the “think about it” section in the sidebar, or have to look at the exended section of the post.
