Human-caused habitat loss and fragmentation are primary drivers of species declines and extinctions. Key examples of human-induced habitat loss include deforestation, agricultural expansion, and urbanization. Habitat destruction and fragmentation can increase the vulnerability of wildlife populations by reducing the space and resources ...
Coastal wetlands also reduce pollution from human waste, [41] [42] remove excess nutrients from the water column, [43] trap pollutants, [44] and sequester carbon. [45] Further, near-shore wetlands act as both essential nursery habitats and feeding grounds for game fish , supporting a diverse group of economically important species.
Marine conservation is informed by the study of marine plants and animal resources and ecosystem functions and is driven by response to the manifested negative effects seen in the environment such as species loss, habitat degradation and changes in ecosystem functions [1] and focuses on limiting human-caused damage to marine ecosystems ...
Water pollution also reduces the ecosystem services such as drinking water provided by the water resource. Sources of water pollution are either point sources or non-point sources. [155] Point sources have one identifiable cause, such as a storm drain, a wastewater treatment plant, or an oil spill. Non-point sources are more diffuse.
Species will be pushed out of their habitat either directly by habitat destruction or indirectly by fragmentation, degradation, or pollution. Any efforts to protect the world's remaining natural habitat and biodiversity will compete directly with humans' growing demand for natural resources, especially new agricultural lands. [56]
For much of human history, nature was seen as a resource that could be controlled by the government and used for personal and economic gain. The idea was that plants only existed to feed animals and animals only existed to feed humans. [2] The value of land was limited only to the resources it provided such as fertile soil, timber, and minerals.
Efforts are made to preserve the natural characteristics of Hopetoun Falls, Australia, without affecting visitors' access.. The term conservation biology and its conception as a new field originated with the convening of "The First International Conference on Research in Conservation Biology" held at the University of California, San Diego in La Jolla, California, in 1978 led by American ...
This category lists some of the species that have become extinct due to human activity, whether intentionally or unintentionally. If a more specific reason is known, the species should also be assigned to a subcategory of Category:Species by threat. They may also need to be placed in Category:Extinctions since 1500.
