    English: In this paper we afford a quantitative analysis of the sustainability of current world population growth in relation to the parallel deforestation process adopting a statistical point of view. We consider a simplified model based on a stochastic growth process driven by a continuous time random walk, which depicts the technological ...

    Coral reefs are dying around the world. [147] Human activities have substantial impact on coral reefs, contributing to their worldwide decline. [148] Damaging activities encompass coral mining, pollution (both organic and non-organic), overfishing, blast fishing, as well as the excavation of canals and access points to islands and bays.

    en.wikipedia.org/wiki/Deforestation_and_climate...

    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.

  5. 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 ...

    The period since 1950 has brought "the most rapid transformation of the human relationship with the natural world in the history of humankind". [1] Almost one-third of the world's forests, and almost two-thirds of its grassland, have been lost to human agriculture—which now occupies almost half the world's habitable land.

    Many [quantify] people value the complexity of the natural world and express concern at the loss of natural habitats and of animal or plant species worldwide. [53] Probably the most profound impact that habitat destruction has on people is the loss of many valuable ecosystem services.

    en.wikipedia.org/wiki/Environmental_issues

    Environment destruction caused by humans is a global, ongoing problem. [4] Water pollution also cause problems to marine life. [5] Some scholars believe that the projected peak global population of roughly 9-10 billion people could live sustainably within the earth's ecosystems if humans worked to live sustainably within planetary boundaries.

    The increase in population also has led people to rely on cropping as a source of income, but many do not take measures to protect the soil, [11] due to low income. [12] The current methods create too much pressure on other environmental aspects, such as forests, and are not sustainable. [13] There are also ecological causes of the poor soil ...
