Like many freshwater environments, the Deschutes River in Oregon is under pressure from development, pollution, and climate change. Many rivers, streams and lakes in the Deschutes Basin do not meet Oregon water quality standards–where state water quality monitoring assesses levels of bacteria, pH, dissolved oxygen, temperature, and fine sediment....

Save our Bogs! Culture, Conservation and Climate Action in Ireland’s Peatlands

Characterized by long-term accumulation under waterlogged conditions, peatlands exist on every continent and account for 3-4% of the global land surface. Small but mighty, these often overlooked wetland environments are estimated to hold as much as one-third of the world’s organic carbon in their soil—twice the amount found in...

Sargassum Surge: How Seaweed is Transforming our Oceans and Coastal Ecosystems

Until recently, Sargassum–a free-floating seaweed–was distributed throughout the Sargasso Sea, the north Caribbean Sea, and the Gulf of Mexico. But in the space of a decade, this seaweed has, as one scientist remarks, “Gone from a nonfactor to the source of a terrible crisis.” Driven by climate change, anomalous...

A Drop in the Ocean: Restoring London’s Tidal Thames

The United Kingdom has grappled with wastewater management problems for decades.

Problems reached a...

In...

Bringing Fish Back: Reviving Britain’s Freshwater Habitats with the Wild Trout Trust

Freshwater covers less than 1% of the Earth’s surface but has an outsized impact on global ecosystems, supporting more than 10% of all known species, reports the World Wildlife Fund. Freshwater environments such as rivers and wetlands provide significant scientific, economic, and cultural value. But pressure from climate change,...
