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 livelihoods of millions of people and species are at risk with deforestation. The act is a domino effect that affects multiple aspects of a community, ecosystem, and economy. [9] Many African nations have begun to implement restoration projects to reverse the effects of deforestation.
Nigeria has experienced an increase in deforestation in part due to expansion of agriculture, lumbering, and urban growth. These land-use changes are driven by population increase and poverty. [13] Natural resources are not limitless, and the following consequences can arise from the careless and excessive consumption of these resources:
Deforestation is often done for several reasons, often for either agricultural purposes or for logging, which is the obtainment of timber and wood for use in construction or fuel. [7] Deforestation causes many threats to wildlife as it not only causes habitat destruction for the many animals that survive in forests, as more than 80% of the ...
There are many different reasons why conservation is important. Some of the most important reasons include: To protect biodiversity: Biodiversity is the variety of life on Earth. It includes the variety of plants, animals, and microorganisms, as well as the variety of ecosystems.
Natural forests are extremely biodiverse, with a wide range of organisms using them as their habitat. But oil palm plantations are the opposite. But oil palm plantations are the opposite. Studies have shown that oil palm plantations have less than 1% of the plant diversity seen in natural forests, and 47–90% less mammal diversity. [ 110 ]
Deforestation in the Democratic Republic of the Congo has been caused partly by unregulated logging and mining, but mostly by the demands made by the subsistence activities of a poor population. In the east of the country, for example, more than 3 million people live less than a day's walk from Virunga National Park. Wood from the park's ...
