The environment will be the focus of two days of activities in Westport this weekend -- commencing with a brook cleanup and culminating with the screening of a documentary film about the globe's melting glaciers.

In all, five events are planned as part of GreenDay, an annual environmental-awareness program organized by Staples High School's Club Green.

Among them are gardening and animal demonstrations at Wakeman Town Farm, nature walks and wildlife programs at Earthplace, a tour of the town's waste-water treatment plant, and a volunteer cleanup of Dead Man's Brook off Imperial Avenue.

The weekend's grand finale will be the screening of the award-winning film "Chasing Ice," in which time-lapse photography to documents that glaciers around the world are melting.

The screening will be Sunday at 4 p.m. in the town hall auditorium.

The show is sponsored by the nonprofit Westport Cinema Initiative, and a discussion on climate change will follow, the group said. Tickets are $10, and proceeds benefit the cinema initiative, which is raising money to build a multi-screen movie house off Main Street.

National Geographic photographer James Balog had been skeptical about climate change, so he and his team crisscrossed the arctic placing time-release cameras to photograph glaciers over time.

The resulting time-lapse video compressed years into seconds and shows mountains of ice melting and disappearing, the cinema initiative said.

Parts of the 75-minute film were shot in Alaska and Montana, and in Iceland, Greenland, France, Italy and Denmark.

Released in December 2012, "Chasing Ice" was judged best documentary at the Berkshire, Big Sky and Crested Butte film festivals and won audience awards and more than a dozen film festivals, according to the film's website.

On Saturday, Wakeman Town Farm is offering three hours of activities between 1 and 4 p.m.

The farm and education center will offer tours of its gardens and livestock areas, a hands-on demonstration of square-foot gardening and a homesteading workshop.

The farm also will dedicate a new greenhouse and formally thank the Westport Woman's Club for its support of the farm.
