Bill Resnick talks with Bryan Palmer about the history of and relationship between anarchism and marxism, particularly prior to the Bolshevik Revolution. Palmer discusses the socialist roots of the two political tendencies, explaining how anarchists and marxists aimed for roughly the same revolutionary outcomes. He compares their different though complementary approaches to creating a better world. In light of historic inequalities re-emerging, he also argues for re-kindling the dialogue between anarchists and marxists.

Bryan Palmer is a historian at Trent University in Canada. This is a two part interview. The second half will air on next week's show and be linked through this page.

Laurie Mercier talks with Stefanie Penn Spear of the environmental news website Ecowatch.org about the big stories of the past year. These include increasing recognition of human-caused climate change, toxins in consumer products, the dangers of fracking (including mining for sand, earthquakes, use and contamination of water with radioactivity and toxic chemicals) as well as more positive news about tax credits for wind farms, sustainable agriculture, and communities moving to100% renewable energy.

Movie Moles Denise Morris and Jan Haaken revisit Michael Moore's 2002 Bowling for Columbine in the aftermath of the shootings in Newtown. They discuss the film's debunking of conventional explanations and its exploration of the multiple factors involved in such incidents, including fears of one's fellow citizens, racism, and militarism. They also consider the misleading resort to stories of mental illness in current debates, when people with mental illness are more likely to be victims than perpetrators of violence.
