We'll learn about the kinds of animals that live in urban environments and the challenges they face! One young Australian listener wants to know why wombats, kangaroos and koalas hang out in the countryside rather than the city. Dr. Mark Eldridge from the Australian Museum Research Institute tackles that one. And we turn our focus to one particular urban dweller, the raccoon, with York University raccoon expert Suzanne MacDonald. She lives in Toronto, which has one of the most dense populations of raccoons in the world. She helps answer why raccoons eat garbage, how long they live and why they look like they're wearing masks.
