Peatlands are very often the setting for chilling folklore. But they serve an important function - for the climate and biodiversity. They’re capable of absorbing and storing large amounts of carbon dioxide, thereby helping to mitigate the climate crisis. Nevertheless, bogs are still being destroyed all over the world. In Finland, peatlands are being drained to extract peat and generate energy. With dramatic consequences: less than half of all the country’s bogs are still intact. Tero Mustonen is a climatologist. He founded the organization Snowchange, to protect and save peatlands. Together with members of his village, Snowchange sued the energy company responsible for the destruction of the Linnunsuo wetland. Mustonen’s organization is now engaged in the worldwide fight to salvage and rewild biotopes.
