Up Close and Toxic. Most people would say they feel safest in their own homes. But toxicologists have found that levels of most indoor air pollutants exceed those found outdoors. This film makes the sources of pollutants easy to understand, and offers tips for safer practices, materials, and cleaning agents.

Green Tuesdays: Films & Lectures on Sustainability is the enlightening and entertaining series of lectures, films, and conversations on sustainable living brought to you by The Natural Step Monona and the Monona Public Library.

Green Tuesdays are on the second and fifth Tuesdays of the month, September through May. The series is free and open to the public. Green Tuesdays are at the Monona Public Library. They start at 6:30 and run until 8:00, with great conversations often pushing the conclusion a bit past that hour.

Whole Foods serves treats, so come early for delightful food and drink.

Green Tuesdays films are supported by the Dane County Environmental Council.
