Iceland Has Almost Zero Trees —Scientists Are Doing Something Insane to Fix It

Iceland was once covered in forest. Within just three centuries of human settlement, nearly all of it was gone — and the soil went with it. This video explores one of the world's most dramatic environmental collapses and the 140-year effort to reverse it. From buried farmsteads and two-week sandstorms to carbon sequestration breakthroughs and birds that have never existed in Iceland before, this is the story of what happens when a land loses its foundation — and what it actually takes to get it back. Including an unexpected twist: the very plant introduced to save the soil may now be one of its biggest threats.
