Designation of marine protected areas (MPAs) is increasing as humans seek to combat overexploitation of marine resources and preserve the integrity of the ocean’s unique biodiversity. At present there are over 1300 MPAs. The primary legal responsibility for the designation of MPAs falls to individual countries, but protection of the marine environment at large scales is also critical because oc...

Water shortage and overexploitation of groundwater (GW) have become the key factors restricting development Xiongan New Area (XNA), environmental management Baiyangdian Lake, social economic surrounding areas. This study used a numerical GW flow model to quantitatively analyze changes shallow level reserves plain area Daqing River Basin over next 15 years (2021–2035) under different artificial ...

Wildlife faces a number of threats due to human activity, including overexploitation from excessive and/or illegal trade. The Convention on International Trade in Endangered Species Wild Fauna and Flora (CITES) is the main international legal instrument address such overexploitation. However, not all species threatened by trade are protected CITES, leading criticism that it an for preservation ...

Continuing population and consumption growth will mean that the global demand for food will increase for at least another 40 years. Growing competition for land, water, and energy, in addition to the overexploitation of fisheries, will affect our ability to produce food, as will the urgent requirement to reduce the impact of the food system on the environment. The effects of climate change are ...

—Migratory barriers, habitat loss, entrainment in irrigation canals, and overexploitation, especially at times of aggregation, have been suggested to explain the failure of Yellowstone River saugers Sander canadensis to return to historical abundances after a late-1980s decline that was attributed to drought. These factors are thought to affect saugers throughout their range and migratory large...

Beginning with an outline of uncertainties about the number of species on Earth today, this paper addresses likely causes and consequences of the manifest acceleration in extinction rates over the past few centuries. The ultimate causes are habitat destruction, alien introductions, overexploitation and climate change. Increases in human numbers and per capita impacts underlie all of these. Agai...
