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 ...
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 ...
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 world population may decline through a preference for fewer children. [26] If developing world demographics are assumed to become developed world demographics, and if the latter are extrapolated, some projections suggest an extinction before the year 3000.
Instead, it impacts the whole country as low wages for high-risk mining worsen poverty rates, exacerbating negative social impacts such as conflict, higher crime rates, and child mortality. The effects of the exploitation of natural resources in the local community of a developing country are also exhibited in the impacts from the Ok Tedi Mine .
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.
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 ...
Scientists assert that human activity has pushed the earth into a sixth mass extinction event. [5] [6] The loss of biodiversity has been attributed in particular to human overpopulation, continued human population growth and overconsumption of natural resources by the world's wealthy.
