  2. Deforestation - Wikipedia

    en.wikipedia.org/wiki/Deforestation

    Deforestation is defined as the conversion of forest to other land uses (regardless of whether it is human-induced). [14] Deforestation and forest area net change are not the same: the latter is the sum of all forest losses (deforestation) and all forest gains (forest expansion) in a given period. Net change, therefore, can be positive or ...

  3. Deforestation and climate change - Wikipedia

    Land use change, especially in the form of deforestation, is the second largest source of carbon dioxide emissions from human activities, after the burning of fossil fuels. [4] [5] Greenhouse gases are emitted from deforestation during the burning of forest biomass and decomposition of remaining plant material and soil carbon.

    The environmental impact of irrigation includes the changes in quantity and quality of soil and water as a result of irrigation and the ensuing effects on natural and social conditions at the tail-end and downstream of the irrigation scheme. The impacts stem from the changed hydrological conditions owing to the installation and operation of the ...

  6. Habitat destruction - Wikipedia

    en.wikipedia.org/wiki/Habitat_destruction

    Probably the most profound impact that habitat destruction has on people is the loss of many valuable ecosystem services. Habitat destruction has altered nitrogen, phosphorus, sulfur, and carbon cycles , which has increased the frequency and severity of acid rain , algal blooms , and fish kills in rivers and oceans and contributed tremendously ...

  7. Desertification - Wikipedia

    en.wikipedia.org/wiki/Desertification

    Human population dynamics have a considerable impact on overgrazing, over-farming and deforestation, as previously acceptable techniques have become unsustainable. [16] There are multiple reasons farmers use intensive farming as opposed to extensive farming but the main reason is to maximize yields. [17]

  8. Environmental degradation - Wikipedia

    en.wikipedia.org/wiki/Environmental_degradation

    When natural habitats are destroyed or natural resources are depleted, the environment is degraded; direct environmental degradation, such as deforestation, which is readily visible; this can be caused by more indirect process, such as the build up of plastic pollution over time or the buildup of greenhouse gases that causes tipping points in ...
