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.
A full-grown tree produces about 100 kilograms (220 lb) of net oxygen per year. [44] Acting as a carbon sink. Therefore, they are necessary to mitigate climate change. [45] Aiding in regulating climate. For example, research from 2017 shows that forests induce rainfall.
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.
The U.K. government said it has received commitments from leaders representing more than 85% of the world’s forests to halt and reverse deforestation by 2030. At COP26, over 100 countries pledge ...
One result is that shifting cultivation is not the primary cause of deforestation in all world regions, while transport extension (including the construction of new roads) is the largest single proximate factor responsible for deforestation. [19] Habitat size and numbers of species are systematically related.
Deforestation in the Maranhão state, Brazil, in July 2016. The Amazon rainforest, spanning an area of 3,000,000 km 2 (1,200,000 sq mi), is the world's largest rainforest. It encompasses the largest and most biodiverse tropical rainforest on the planet, representing over half of all rainforests.
From 1993 to 1997, as Young People's Trust for the Environment, the organisation ran the Young Naturalist of the Year Awards in conjunction with BT to encourage children aged 8–13 to carry out research on anything from insects to elephants, nature trails to rain forests and acid rain to global warming. Winners received a dolphin trophy and £ ...
