LEWISBURG, Pa. — The documentary, "The City Dark," will be shown Tuesday, Nov. 5, at 7:30 p.m. at the Campus Theatre in Lewisburg.

The Green Screens film is co-sponsored by the Bucknell University Environmental Center's Green Screen film series and presented as part of the University's ongoing Film/Media Series.

Admission is $2 per person; Campus Dollars are accepted. The Campus Theatre is located at 413 Market St. in Lewisburg.

Directed by Ian Cheney, "The City Dark" chronicles the disappearance of darkness, leading viewers on a quest to understand how light pollution affects people and the planet. The film explores the effects of light pollution not only on star-gazing but on sea turtles and birds confused by the lights of cities.

After moving to light-polluted New York City from rural Maine, the filmmaker asked, "Do we need the dark?" Exploring the threat of killer asteroids in Hawai'i, tracking hatching turtles along the Florida coast, and rescuing injured birds on Chicago streets, Cheney unravels the myriad implications of a globe glittering with lights-including increased breast cancer rates from exposure to light at night, and a generation of kids without a glimpse of the universe above.

Weather permitting, Ned Ladd, associate professor of physics and astronomy, will present a free viewing at the Bucknell University Observatory after the screening.

The next screening is scheduled for Dec. 3. "Trashed: No Place for Solid Waste," examines the extent and effects of the global waste problem. The beauty of the planet from space forms a violent contrast to the scenes of human detritus across the globe. Vast landscapes in China are covered in tons of rubbish. The wide waters of the Ciliwung River in Indonesia are barely visible under a never-ending tide of plastic. Children swim among leaking bags; mothers wash in the sewage-filled supply. Each year, we throw away 58 billion disposable cups, billions of plastic bags, 200 billion liters of water bottles and billions of tons of household waste, toxic waste and e-waste.
