Lights, camera, environmental action!
2016 Environmental Film Festival

Now in its 24th year, the Environmental Film Festival in the Nation’s Capital begins Tuesday, with more than 150 films to be screened at theaters, museums, embassies, universities and libraries around the Washington area. About 90 percent are documentaries; some already have been commercially released. Many of the screenings include discussions with filmmakers, experts and other guest speakers.

A sampling:

“Tiny Giants 3D,” narrated by British actor Stephen Fry, uses specialty cameras to give viewers the perspective of a chipmunk and a grasshopper mouse struggling to survive in worlds — a forest for the former, the Arizona desert for the latter — where everything, especially the predators, is a lot bigger than they are.

In “Moving the Giants,” an arborist seeks to rescue giant California coast redwoods by using a mass cloning initiative to move them northward to a more hospitable environment.

“Night Moves,” a thriller about eco-terrorism, stars Jesse Eisenberg, Dakota Fanning and Peter Sarsgaard as activists who want to blow up a dam.

In “City of Trees,” a D.C. nonprofit gets a grant in the depths of the recession to hire 150 unemployed people to plant trees in parks — an effort that offers hope to many but also faces challenges.

“Merchants of Doubt” investigates pundits who present themselves as scientific authorities but instead are trying to spread doubt about such well-researched threats as toxic chemicals and climate change.

“Bluespace” uses the sci-fi concept of “terraforming” — changing another planet’s atmosphere to make it capable of sustaining human life — to examine how we are failing to take care of the environment on Earth.

Experimental musician and performance artist Laurie Anderson made “Heart of a Dog” about the death of her beloved rat terrier Lolabelle, and uses it to illuminate issues of life, loss and memory.

Antarctic krill are tiny, but they are of great importance: They’re a primary food source for whales, seals and penguins. The alarming decline in their population is chronicled in “License to Krill.”

A troupe of macaque monkeys in Sri Lanka face life-or-death situations in “Monkey Kingdom,” narrated by Tina Fey.

“Containment” examines the challenge of handling the radioactive waste from bombs and power plants that will last for 10,000 years.

Many of the screenings are free. The festival ends March 26. Get the full schedule at dceff.org, where you also can download the printed program.
