Last week, the United Nations released a biodiversity report warning that one million species are at risk for extinction in the coming decades, including more than 40% of amphibian species, nearly 33% of reef-forming corals, and more than a third of all marine mammals. Today on the show, we explore the magnitude of the report’s […]
Extinction and Survival Under Capitalism with Anna Tsing
The mushroom, Anna Tsing argues, provides a rich metaphor for life in the anthropocene. For today’s show, we speak with Professor Tsing about her book The Mushroom at the End of the World, a study in capitalist destruction and collaborative survival through the lens of the highly-prized matsutake mushroom and its winding chain of commerce. Anna […]
Why Some Species Are More Likely To Go Extinct
The earth has experienced five mass extinctions since life first formed on this planet four billion years ago, with the result that 99.99 percent of every species the earth has ever seen is now extinct. Most scientists agree that we live now in the midst of a sixth mass extinction event, one potentially caused by […]
Foraging, Wild Edibles, and the Arboretum
In this episode of the Perpetual Notion Machine, PNM’s hunter/gatherer Lincoln Tice explores the search for wild edibles, or in other words, foraging. With a little bit of education, anyone can find edible plants and fruits right from their own backyard or neighborhood. Lincoln’s guest is Kelly Schwartz, who just happens to also be a […]
Phenology of Snow and the Subnivium
Tonight’s episode of the Perpetual Notion Machine is all about a winter’s treat – snow, or a lack of it this winter. But while we play and make snowmen in the snow, there’s plenty going on by critters and plants underneath the snow cover. In fact, one of our guests tonight, Jonathan Pauli from UW-Madison’s […]
Chronic Wasting Disease
Last week, PNM’s Lincoln Tice explored the sustainability of hunting, primarily as a source for food. Tonight, Lincoln continues the discussion with an epidemic that’s infecting deer populations throughout the state, Chronic Wasting Disease. His guest is Michael Samuel, Professor Emeritus in forest and wildlife ecology at UW-Madison. CWD is a fatal neurodegenerative disease affecting […]
