Peatlands are the superheroes of ecosystems: purifying water, sometimes mitigating flooding and providing a home for rare species. And they beat nearly every system when it comes to carbon storage. Known peatlands only cover about 3 percent of the world’s land surface, but store at least twice as much carbon as all of Earth’s standing forests. And at least one-third of the world’s organic soil carbon, which plays a vital role in mitigating climate change and stabilizing the carbon cycle, is in peatlands.
