Mosses have colonised almost every corner of the Earth’s surface. Evolving from oceanic algae that emerged onto the land 450 million years ago, these very first terrestrial plants became a main source of oxygen for our evolving planet, helping transform it from an arid rock into a lush world. The Magical World of Moss travels to beautiful moss covered landscapes in Japan, Iceland, France and Denmark to meet scientists and experts investigating its astonishing properties and potential. Science is only beginning to understand the secrets and the possibilities of this remarkable plant.
