Satellite photograph of deforestation in Bolivia.Originally dry tropical forest, the land is being cleared for soybean cultivation. [5]Biodiversity hotspots are chiefly tropical regions that feature high concentrations of endemic species and, when all hotspots are combined, may contain over half of the world's terrestrial species.

"This does not involve a reduction of the forest area, but rather a quality decrease in its condition." The forest is still there, but with fewer trees, or fewer species of trees, plants or animals, or some of them affected by plagues. [1] This degradation makes the forest less valuable and may lead to deforestation.
Biodiversity loss happens when plant or animal species disappear completely from Earth or when there is a decrease or disappearance of species in a specific area. Biodiversity loss means that there is a reduction in biological diversity in a given area. The decrease can be temporary or permanent.
Deforestation is a cause of human-induced habitat action destruction, by cutting down habitats of different species in the process of removing trees. 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]
While habitat fragmentation is often associated with its effects on large plant and animal populations and biodiversity, due to the interconnectedness of ecosystems there are also significant effects that it has on the microbiota of an environment. Increased fragmentation has been linked to reduced populations and diversity of fungi responsible ...
Water pollution can lead to the death of fish and other aquatic organisms, and the spread of disease. Loss of biodiversity: This is the decline in the number and variety of plant and animal species. Loss of biodiversity can have a number of negative impacts, including the disruption of food chains and the loss of ecosystem services.
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 of the Amazon rainforest is the most dramatic example of a massive, continuous ecosystem and a biodiversity hotspot being under the immediate threat from habitat destruction through logging, and the less-visible, yet ever-growing and persistent threat from climate change. [11] [12]
