Reduction Of Biodiversity Definition

Recognising safeguarding and using the potential and diversity of nature is critical for food security and sustainable agriculture.

Reduction of biodiversity definition. Loss of biodiversity has a poor impact on the ecosystem. The main cause of the loss of biodiversity can be attributed to the influence of human beings on the world s ecosystem in fact human beings have deeply altered the environment and have modified the territory exploiting the species directly for example by fishing and hunting changing the biogeochemical cycles and transferring species from one area to. Eight major causes of biodiversity are as follows. Reduction of biodiversity entails a reduction of options for ensuring more diverse nutrition enhancing food production raising incomes coping with environmental constraints and managing ecosystems.

Habitat loss and fragmentation. Illegal wildlife trade 8. Refers to either the ongoing extinction of species at a global level or the local reduction or loss of species in a given habitat. Reduction in biodiversity can affect decomposition rates vegetation biomass production and in the marine environment affect fish stocks 15 16 17 18.

The latter phenomenon can be temporary or permanent. Population growth and over consumption 7. Habitat loss and fragmentation 2. A habitat is the place where a plant or animal naturally.

Causes of the loss of biodiversity. Biodiversity is a term which describes every living organism within a single ecosystem or habitat including numbers and diversity of species and all environmental aspects such as temperature oxygen and carbon dioxide levels and climate. Over exploitation for commercialization 3. Loss of biodiversity definition.

Biodiversity underpins ecosystem function and the provision of ecosystem services. Biodiversity loss includes the extinction of species plant or animal worldwide as well as the local reduction or loss of species in a certain habitat resulting in a loss of biological diversity. Biodiversity can be measured globally or in smaller settings such as ponds. Global climate change 6.

The totality of genes species and ecosystems in a defined area. Among other factors the diversity of all living things depends on temperature precipitation altitude soils geography and the presence of other species the study of the spatial distribution of organisms species and ecosystems is the science of biogeography. Biodiversity is not evenly distributed rather it varies greatly across the globe as well as within regions. Biodiversity loss therefore threatens the provision of goods and services provided by ecosystems.
