It's on every continent, and in every terrestrial ecosystem. It's beneath our feet on most hikes and it's often overlooked: lichens! In this episode, Dr. Troy McMullin, the chief lichenologist at the Canadian Museum of Nature, gives an insightful overview of what lichens are, describes their many interesting strategies, and shares why you should care. We dive into their unique symbiotic partnership, their range of amazing structures, and how they are an important part of our future here on Earth.
