In this week's episode Dave and Ollie talk about the oil price, despite not really wanting to and finding it all very complicated and difficult.  Are lower oil prices bad or good for climate change? Does anyone really know? Anyone?In mammal news, they've got door-to-door squirrel deliveries and a disagreement about beavers.And what's this about the curious incident of the Government paying a company that makes and sells LED lightbulbs to start using LED lightbulbs?All this, and they find time to come over all Patrick Moore, pondering inexpertly whether climate change is being caused by supernovae (clue: it isn't).Sustainababble is a weekly podcast for and by greeny types who don’t really know what’s going on. It comes out every Monday.Music by Dicky Moore from Bearcraft.Available on iTunes, Stitcher, Soundcloud, and on the sustainababble website. Visit us at @thebabblewagon.
