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 ...
Deforestation in the United States was affected by many factors. One such factor was the effect, whether positive or negative, that the logging industry has on forests in the country. Logging in the United States is a hotly debated topic as groups who either support or oppose logging argue over its benefits and negative effects.
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 period since 1950 has brought "the most rapid transformation of the human relationship with the natural world in the history of humankind". [106] Through 2018, humans have reduced forest area by ~30% and grasslands/shrubs by ~68%, to make way for livestock grazing and crops for humans. [107]
Deforestation is the main land use change contributor to global warming, [62] Between 1750 and 2007, about one-third of anthropogenic CO 2 emissions were from changes in land use - primarily from the decline in forest area and the growth in agricultural land. [63] primarily deforestation.
There is a common relationship between air pollution and population. Africa widely diverse between areas that are overpopulated versus areas that are scarcely populated. In regions where there is little industrial development and few people, air quality is high. Vice versa, in densely populated and industrialized regions the air quality is low ...
Maathai focused for efforts on battling deforestation issues, and how to fix various other forest-related issues in order to improve the overall quality of life for the women and children in Kenya. Maathai began with introducing tree planting programs and regimes into local communities/ targeting communities with little access to basic natural ...
