The True History Of Cowboys, Getting Beyond Fossil Fuels, And The Volcano Explorer
They may be icons of the old west, but cowboys aren't just an American phenomenon. Today, we learn the long history of the horseback herdsmen, whose roots go back to Africa. Then, we discuss climate change and the complexities of reducing fossil fuel use with environmentalist Bill McKibben. Later, we ask Sam Cossman why on earth he climbs into active volcanoes and what he hopes to gain from doing so.
