With yesterday being Earth Day, I started thinking about all the various environmental-themed movies that we’ve seen over the years. They span almost every genre, from documentary and political thriller, to family film, to sci-fi and horror… the thing is, a lot of them aren’t so great. Maybe because some of them are too preachy, while others are just kind of boring. Still, I thought I’d put together a poll of some of the stand-outs and ask you to vote on your favourite. Feel free to nominate even more eco-friendly titles in the comments below!
