Conservation biologist Kent McFarland will share how listeners can contribute to research and conservation policy with their smartphone, and discuss the alarming levels of toxic mercury in ecosystems on Vermont’s mountaintops. National correspondent Bob Ney brings us up to date on the big stories from the week. We get to talk donuts with Jordan Barry of Seven Days (but, alas, no samples). And Roman Catholic Bishop Christopher Coyne discusses the moral leadership needed in the wake of last week’s attack on the U.S. Capitol.
