('music) Today, we´re on the beautiful island of Kalamos, Greece, to learn more about rewilding. We met Ted Kafa'kis, who runs the organization Terra Sylvestris. He shown us a video about rewilding, which refers to the introduction of animal and plant species in areas where they originally occured. A chain reaction was set in motion, increasing biodiversity and bringing the ecosystem back into balance. (upbaeat music) Since 90% of Kalamos population left the island in the last century and now only 200 people live here, Ted believes that the island where he grew up is an excellent place for rewilding.
