  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. Human overpopulation - Wikipedia

    en.wikipedia.org/wiki/Human_overpopulation

    Indeed, some analysts claim that overpopulation's most serious impact is its effect on the environment. [142] Some scientists suggest that the overall human impact on the environment during the Great Acceleration , particularly due to human population size and growth, economic growth , overconsumption, pollution , and proliferation of ...

  4. Overpopulation - Wikipedia

    en.wikipedia.org/wiki/Overpopulation

    Overpopulation or overabundance is a state in which the population of a species is larger than the carrying capacity of its environment.This may be caused by increased birth rates, lowered mortality rates, reduced predation or large scale migration, leading to an overabundant species and other animals in the ecosystem competing for food, space, and resources.

  5. Habitat destruction - Wikipedia

    en.wikipedia.org/wiki/Habitat_destruction

    There are also feedbacks and interactions among the proximate and underlying causes of deforestation that can amplify the process. Road construction has the largest feedback effect, because it interacts with—and leads to—the establishment of new settlements and more people, which causes a growth in wood (logging) and food markets. [19]

  6. Deforestation in India - Wikipedia

    en.wikipedia.org/wiki/Deforestation_in_India

    Deforestation in India is the widespread destruction of major forests in India. It is mainly caused by environmental degradation by farmers, ranches, loggers and plantation corporations. In 2009, India ranked 10th worldwide in the amount of forest loss , [ 1 ] where world annual deforestation is estimated as 13.7 million hectares (34 × 10 ^ 6 ...

  7. Human impact on the environment - Wikipedia

    However, attributing overpopulation as a cause of environmental issues is controversial. Demographic projections indicate that population growth is slowing and world population will peak in the 21st century, [34] and many experts believe that global resources can meet this increased demand, suggesting a global overpopulation scenario is unlikely.

  8. Biodiversity loss - Wikipedia

    en.wikipedia.org/wiki/Biodiversity_loss

    [58] [59] Causes for the decline in insect population are similar to those driving other biodiversity loss. They include habitat destruction, such as intensive agriculture, the use of pesticides (particularly insecticides), introduced species, and – to a lesser degree and only for some regions – the effects of climate change. [60]
