The Green Sahara desert in northern Niger is one of the harshest, most desolate places on earth. The region’s abundance of fossils, however, makes it a destination for scientists. University of Chicago paleontologist Paul Sereno tells Worldview what his team uncovered during his recent expedition there. Also, Chicago journalist Kari Lydersen argues that hard rock mining – mining for substances like gold, silver and nickel – can be even more detrimental to the environment than traditional coal mining. And Worldview film contributor Milos Stehlik discusses the Robert Bresson retrospective at the Siskel Film Center.
