Wetlands: Carbon sinks in peril
Around the world, wetlands are still disappearing three times faster than forests, erasing entire ecosystems. While tropical rainforests are often called the lungs of the Earth, wetlands are described as the kidneys. They can absorb large quantities of water, filtering pollutants and helping to prevent floods. They have also become key allies in the fight against climate change, as they can capture CO2 from the atmosphere. In this episode of Down to Earth, we explore what is being done to bring damaged wetlands back to life.
