  2. Human impact on river systems - Wikipedia

    en.wikipedia.org/wiki/Human_impact_on_river_systems

    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]

  3. River ecosystem - Wikipedia

    en.wikipedia.org/wiki/River_ecosystem

    This stream operating together with its environment can be thought of as forming a river ecosystem. River ecosystems are flowing waters that drain the landscape, and include the biotic (living) interactions amongst plants, animals and micro-organisms, as well as abiotic (nonliving) physical and chemical interactions of its many parts.

  4. Anthropization - Wikipedia

    en.wikipedia.org/wiki/Anthropization

    To power the ever-growing human race, energy is needed. Power-harvesting structures are built to harness energy, such as dams, windmills, and nuclear reactors. These sources of energy ultimately fuel the rest of anthropological activity and are essential in this way. However many of these methods have consequences.

    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.

    This stream operating together with its environment can be thought of as forming a river ecosystem. River ecosystems are flowing waters that drain the landscape, and include the biotic (living) interactions amongst plants, animals and micro-organisms, as well as abiotic (nonliving) physical and chemical interactions of its many parts.

  7. Human impact on the nitrogen cycle - Wikipedia

    en.wikipedia.org/wiki/Human_impact_on_the...

    Human activities account for over one-third of N 2 O emissions, most of which are due to the agricultural sector. [2] This article is intended to give a brief review of the history of anthropogenic N inputs, and reported impacts of nitrogen inputs on selected terrestrial and aquatic ecosystems .

  8. Anthropogenic biome - Wikipedia

    en.wikipedia.org/wiki/Anthropogenic_biome

    Anthropogenic biomes, also known as anthromes, human biomes or intensive land-use biome, describe the terrestrial biosphere in its contemporary, human-altered form using global ecosystem units defined by global patterns of sustained direct human interaction with ecosystems. Anthromes are generally composed of heterogeneous mosaics of different ...

  9. River - Wikipedia

    en.wikipedia.org/wiki/River

    Rivers and river ecosystems are threatened by water pollution, climate change, and human activity. The construction of dams, canals , levees , and other engineered structures has eliminated habitats, has caused the extinction of some species, and lowered the amount of alluvium flowing through rivers.
