The relationship between humans and rivers, which represent freshwater environments, is complicated. Rivers serve primarily as a freshwater resource and as sinks for domestic and industrial waste water. The consequences from this usage occur from diverse activities and root themselves in complex, interdisciplinary systems and practices. [4]
Anthropogenic influences on river systems. [46] Examples are mainly from settings with a modest technological influence, especially in the period of about 10,000 to 4000 cal yr BP. Humans exert a geomorphic force that now rivals that of the natural Earth.
The red arrows (and associated numbers) indicate the annual flux changes due to anthropogenic activities, averaged over the 2000–2009 time period. They represent how the carbon cycle has changed since 1750. Red numbers in the reservoirs represent the cumulative changes in anthropogenic carbon since the start of the Industrial Period, 1750–2011.
According to a 2018 study in Nature, 87% of the oceans and 77% of land (excluding Antarctica) have been altered by anthropogenic activity, and 23% of the planet's landmass remains as wilderness. [116] Habitat fragmentation is the reduction of large tracts of habitat leading to habitat loss.
Climate change driven by anthropogenic activities can harm aquatic ecosystems by disrupting current distribution patterns of plants and animals. It has negatively impacted deep sea biodiversity, coastal fish diversity, crustaceans, coral reefs, and other biotic components of these ecosystems. [31]
Schematic representation of the overall perturbation of the global carbon cycle caused by anthropogenic activities, averaged from 2010 to 2019. Since the Industrial Revolution, and especially since the end of WWII, human activity has substantially disturbed the global carbon cycle by redistributing massive amounts of carbon from the geosphere.

In geography and ecology, anthropization is the conversion of open spaces, landscapes, and natural environments by human action. [1] Anthropic erosion is the process of human action degrading terrain and soil. An area may be classified as anthropized even though it looks natural, such as grasslands that have been deforested by humans.
The Holocene extinction, also referred to as the Anthropocene extinction, [3] [4] is an ongoing extinction event caused by human activities during the Holocene epoch. This extinction event spans numerous families of plants [ 5 ] [ 6 ] [ 7 ] and animals, including mammals , birds, reptiles, amphibians , fish, and invertebrates , impacting both ...
