Philip Fearnside’s research has calculated the costs of losing the Amazon on account of deforestation, dams and highways The Amazon rainforest has been described in terms of its enormous size, biodiversity and importance to the global climate. But for Philip Fearnside, understanding the forest has also meant asking a more practical question: what does it…

In 1999, scientists dropped 45 tons of wollastonite over a 29-acre New Hampshire watershed to replace calcium lost to acid rain; by 2013, it was exporting 30 times more inorganic nitrogen than nearby watersheds

In 1999, scientists dropped 45 tons of wollastonite over a 29-acre New Hampshire watershed A large-scale effort to restore an American forest damaged by acid rain had an unexpected environmental effect when added nutrients caused a huge increase in nitrogen flowing into nearby streams. In October and November 1999, researchers spread about 45 short tons…

damselflyRepresenative image from Canva For much of the 20th century, the Santa Cruz River that winds through Tucson, Arizona, existed more as a memory than a living waterway. Groundwater pumping, drought and urban growth drained the riverbed, leaving long stretches of dry sand and scattered pools. Then, in a quiet but transformative experiment, treated wastewater,…

The Amazon River is one of the world’s largest and most powerful river systems, carrying an extraordinary volume of freshwater across South America before emptying into the Atlantic Ocean. Its immense flow is closely connected to the vast Amazon basin, which receives water from rainfall, tributaries and sources in the Andes. The river carries approximately…

From 1915 to 1972, Mount Rainier stocked more than 9 million fish into naturally fishless waters; today 35 mountain lakes still hold breeding non-native populations that displace amphibians and alter ecosystems

Mount Rainier’s glaciers and snowfields feed a magnificent system of icy streams and mountain lakes. On the surface, these waters look pristine, scattered pools in one of America’s most iconic landscapes. But beneath the surface, scientists are looking at a…

In 2016, conservationists put the bends back into a Lake District river straightened 200 years earlier; within months, Atlantic salmon were spawning there for the first time in centuries

Centuries after people forced a Cumbrian river into a straight, artificial channel, nature has reclaimed its original course in the Lake District, bringing endangered wild fish back to historic spawning grounds almost immediately. In the summer of 2016, conservationists restored a 1.1-kilometre stretch of Swindale Beck near Haweswater by putting its natural bends back into…
