Humans can have a major impact on freshwater systems through water overuse. The same waterways that support wildlife and plants also provide municipal water for cities and towns, and when consumption outstrips the natural regeneration of these waterways, it can negatively affect the ecosystem. Reducing...
Knowing the extent of human influence on the global hydrological cycle is essential for the sustainability of freshwater resources on Earth1,2. However, a lack of water level observations for the world’s ponds, lakes and reservoirs has limited the quantification of human-managed (reservoir) change...
Dry/wet regions are the grid cells with PRCPTOT in the bottom/top 30% of all cells across the global land surface.aOptimized scaling factors based on the one-signal analysis (dots) and their 5–95% CIs (vertical lines) for PRCPTOT trends in dry and wet regions for ALL, ANT, GHG, ...
'The impact we have had on ocean ecosystems has been vastly underestimated. These are the megafauna, the big predators of the sea, and the species we most value. Their depletion not only threatens the future of these fish and the fishers that depend on them, it could also bring about a ...

Since 1970, the most negative impacts on nature have been due to land-use change in terrestrial and freshwater ecosystems [8,39]. The underlying indirect driver has mainly been agricultural intensification and expansion—over one-third of the changes to the terrestrial land surface have been due ...
However, in most other watersheds, the luxury of having enough freshwater to physically disrupt and destroy stratification-induced hypoxia is not a hydrologically or economically feasible option. Manipulating the production of organic matter, the “fuel” for hypoxia, is often the most achievable and...
Coastal populations and wetlands have been intertwined for centuries, whereby humans both influence and depend on the extensive ecosystem services that wetlands provide. Although coastal wetlands have long been considered vulnerable to sea-level rise, recent work has identified fascinating feedbacks between...
Argon and luminescence dating of fossil shell infills from Trinil in Java, where Homo erectus lived, reveals that the hominin-bearing deposits are younger than previously thought; perforated shells, a shell tool and an engraved shell indicate that Homo erectus ate freshwater mussels, used their sh...
