You can certainly pick on Living with Ed (with Ed Begley, Jr.), although I think it's pretty funny in a weird way. Not the best show, but it's entertaining.
But there are other shows that are really good. Two shows that comes to mind are Wa$ted and G-Word, which, for me, have been eye openers to some of our habits that affect the environment. There's also a show called World's Greenest Homes, which is pretty cool. Do NOT watch Renovation Nation because the host is annoying.
I also watch The Green on Sundance Channel, which I find to be awesome. The Green consists of two shows - Big Ideas for a Small Planet and some sort of documentary. The entire segment is produced by Robert Redford.
If you are concerned about climate change at all, you should definitely check out my suggestions for PGTV and Big ideas for a Small Planet on Sundance. It's good stuff.
