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 ...
Global destruction of nature has reached unprecedented extremes. As the United Nations two-week COP16 biodiversity summit kicks off on Monday in Cali, Colombia, here is what you need to know about ...
Habitat size and numbers of species are systematically related. Physically larger species and those living at lower latitudes or in forests or oceans are more sensitive to reduction in habitat area. [23] Conversion to "trivial" standardized ecosystems (e.g., monoculture following deforestation) effectively destroys habitat for the more diverse ...
Red list categories of the IUCN Demonstrator against biodiversity loss, at Extinction Rebellion (2018).. The current rate of global biodiversity loss is estimated to be 100 to 1000 times higher than the (naturally occurring) background extinction rate, faster than at any other time in human history, [25] [26] and is expected to grow in the upcoming years.
Other reasons include low education and inactivity from the government, [23] although the current government has taken some steps to tackle deforestation. [24] Organizations such as Farm Africa are working with the federal and local governments to create a system of forest management. [25]
Deforestation of rainforest. The rate of illegal logging, which is another main cause of deforestation, varies from country to country, such as 50% in Cameroon and 80% in Liberia. In the Democratic Republic of the Congo, deforestation is primarily caused by the needs of the poor citizens, along with unsupervised logging and mining.
The sustainable management of our oceans relies on the ability to influence and guide human use of the marine environment". [12] To counter regression in achieving Goal 14, "swift and coordinated global action is imperative".
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.
