“No Impact Man,” a documentary about a family that attempts to reduce its carbon footprint over a one-year period, will be shown at Worsham Theatre Monday at 7 p.m.

In the film, Colin Beavan attempts to decrease his and his family’s use of resources by giving up things like TV, taxis and takeout, and turns to more green-friendly options like walking and bicycling.

The most important lesson students can learn from the film is that habit change is within their power, said Ellen Usher, assistant professor in educational and counseling psychology, in an e-mail to the Kernel on Sunday.

“Changing our habits may not be easy, but it is essential to a better way of life,” she said.

The Student Sustainability Council and UK Greenthumb  will host the showing, and a post-film discussion will take place to address ways to live sustainably in Lexington.
