Made a New Year’s resolution to free yourself from disposable plastic bags this year? If you’ve kept your resolution this far, Earth Month will bring to public television a film that’ll make you feel great about bagging the bag habit — before scaring you about all the other plastics in your life and their effects on the environment and your health.

More seriously, the eco-documentary “Bag It” sounds like an entertaining and educational primer on disposable plastics and their discontents. Told from the point of view from Jeb Berrier, a regular guy in small town Colorado, “Bag It” begins with the story of a single plastic bag given out with a plastic cup of yogurt — and goes on to explore the far-reaching and unavoidable effects of plastic around the world. Watch the preview:

You can watch “Bag It” free next month — from the comfort of your own home. During Earth Week, a 56-minute version of “Bag It” premiers on public TV stations. Check your local station for air dates and times — or watch the full, 78-minute film with your neighbors at festival and community screenings. The film will be featured at Whole Foods’ Do Something Reel Film Festival, which hits 70 U.S. cities during April — and the filmmakers are planning an additional 100 public screenings across the U.S.
