"Forests, peatlands, deserts and tundra can all absorb and hold stocks of carbon-dioxide (CO2). Of all the carbon held in land-based ecosystems, around 34% can be found in grasslands, data from the World Resources Institute show. That's not much less than the 39% held in forests.
"Whether you look at the Serengeti, the Cerrado in Brazil, whether you look at what's left of the prairies in North America or the steppes of Mongolia -- every single one of our major, iconic grassland habitats is under threat at the moment," Ian Dunn, chief executive of the British conservation organization Plantlife, told CNN.
There's also plenty of it in the United Kingdom, which will host world leaders and climate negotiators in just over a week at the COP26 climate talks in Glasgow, Scotland. Among several items on the agenda is how to protect forests and plant more trees to help slash global emissions.
But Plantlife, among other groups, is campaigning for grasslands to be protected at an international level and part of any deal that emerges in Glasgow."

Marshes are also wonderful carbon sinks and havens of biodiversity and should be cherished and protected with as much fervour as any forest.

There's a park near me with Marsh in the name and I was real disappointed to find it's not actually a marsh.
