Habitat destruction. Map of the world's biodiversity hot spots, all of which are heavily threatened by habitat loss and degradation. Habitat destruction (also termed habitat loss and habitat reduction) occurs when a natural habitat is no longer able to support its native species. The organisms once living there have either moved to elsewhere or ...
These regions contain a high number of plant and animal species and have been subjected to high levels of habitat destruction by human activity, leading to biodiversity loss. Deforestation and increased road-building in the Amazon Rainforest in Bolivia cause significant concern because of increased human encroachment upon wild areas, increased ...
Wildlife conservation. Ankeny Wildlife Refuge in Oregon. Wildlife conservation refers to the practice of protecting wild species and their habitats in order to maintain healthy wildlife species or populations and to restore, protect or enhance natural ecosystems.

Definition. The term habitat fragmentation includes five discrete phenomena: Reduction in the total area of the habitat. Decrease of the interior: edge ratio. Isolation of one habitat fragment from other areas of habitat. Breaking up of one patch of habitat into several smaller patches. Decrease in the average size of each patch of habitat.
v. t. e. Human impact on the environment (or anthropogenic environmental impact) refers to changes to biophysical environments [1] and to ecosystems, biodiversity, and natural resources [2] caused directly or indirectly by humans. Modifying the environment to fit the needs of society (as in the built environment) is causing severe effects [3][4 ...
e. Human activities affect marine life and marine habitats through overfishing, habitat loss, the introduction of invasive species, ocean pollution, ocean acidification and ocean warming. These impact marine ecosystems and food webs and may result in consequences as yet unrecognised for the biodiversity and continuation of marine life forms.
Human–wildlife conflict (HWC) refers to the negative interactions between humans and wild animals, with undesirable consequences both for people and their resources on the one hand, and wildlife and their habitats on the other. HWC, caused by competition for natural resources between human and wildlife, influences human food security and the ...
Bird conservation. The extinction of the dusky seaside sparrow was caused by habitat loss. Bird conservation is a field in the science of conservation biology related to threatened birds. Humans have had a profound effect on many bird species. Over one hundred species have gone extinct in historical times, although the most dramatic human ...
