DW Documentary - Season 8 Episode 45

Peatlands and wetlands play an important role in global warming because they influence the greenhouse gas cycle. But not all bogs are the same. Some bind carbon, while others release it into the atmosphere in the form of carbon dioxide and methane emissions. The film follows the work of two research teams investigating the influence of moors and swamps on the climate. Greenhouse gases escape when permafrost moors melt. But swamp and mire areas that have been thrown out of balance, for example by plantation farming for the production of palm oil, can actually accelerate climate change. The documentary explains what happens when carbon escapes from swamp and moorland areas into the atmosphere and how nature's potential can be used to slow down climate change.
