Overexploitation is the harvesting of animals and plants at a rate that's faster than the species' ability to recover. While often associated with Overfishing, overexploitation can apply to many groups including mammals, birds, amphibians, reptiles, and plants. [11]
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 are dead, leading to a decrease in biodiversity and species numbers .
The World's 100 most threatened species [1] is a compilation of the most threatened animals, plants, and fungi in the world. It was the result of a collaboration between over 8,000 scientists from the International Union for Conservation of Nature Species Survival Commission (IUCN SSC), along with the Zoological Society of London .

Discontinuities in forest areas associated with utility right-of-ways can serve as biodiversity havens for native bees [64] and grassland species, [66] as the right-of-ways are preserved in an early successional stage. Forest fragmentation reduces food resources and habitat sources for animals thus
The major threats to this animal are deforestation and degradation of its habitat. [2] Black finless porpoise Neophocaena phocaenoides: The finless porpoise is often caught in fishing nets across the coasts of Pakistan. Other threats to the species include habitat loss, boat traffic, and pollution. [3] Burrowing vole Hyperacrius fertilis
These sites occurred as a result of humans exploiting an animal's herding behavior and predator-flight instincts. [citation needed] The extinction of the passenger pigeon is another example. [citation needed] In 2023 alone, over 1.8 million distinct human-wildlife conflicts occurred as animal involved auto accidents on roadways, seen as roadkill.
In a recent study using 12 serial aerial photo mosaics from 1948 to 2002, the impact of the return of beavers on openwater area in east-central Alberta, Canada, found that the mammals were associated with a 9-fold increase in openwater area. Beavers returned to the area in 1954 after a long absence since their extirpation by the fur trade in ...
Wild animals can experience injury from a variety of causes such as predation; intraspecific competition; accidents, which can cause fractures, crushing injuries, eye injuries and wing tears; self-amputation; molting, a common source of injury for arthropods; extreme weather conditions, such as storms, extreme heat or cold weather; and natural disasters.
