Climate and environmental superstars

Swamps and wetlands are among our most valuable ecosystems. Their deep brown, oxygen-poor soils can hold thousands of years’ worth of accumulated carbon, safely stored where it doesn’t warm the planet. They alter pollutants out of surface water, keeping streams and rivers clean. They provide nurseries for young fish and homes to thousands of species.

Those species include microbes that form living films known as a “neuston layer.” While these films can resemble oil slicks, they are a natural and healthy part of the wetland.

Wetlands outperform any human technology. Yet humans have ruined many of these precious places, through deliberate destruction or, in the case of the emerald ash borer, through indifference and neglect.
