Wildlife conservationWildlife 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. Major threats to wildlife include habitat destruction, degradation, fragmentation, overexploitation, poaching, pollution, climate change, and the illegal wildlife trade. The IUCN estimates that 42,100 species of the ones assessed are at risk for extinction.
OverpopulationOverpopulation or overabundance is a phenomenon in which a species' population becomes larger than the carrying capacity of its environment. This may be caused by increased birth rates, lowered mortality rates, reduced predation or large scale migration, leading to an overabundant species and other animals in the ecosystem competing for food, space, and resources. The animals in an overpopulated area may then be forced to migrate to areas not typically inhabited, or die off without access to necessary resources.
Ecosystem managementEcosystem management is an approach to natural resource management that aims to ensure the long-term sustainability and persistence of an ecosystem's function and services while meeting socioeconomic, political, and cultural needs. Although indigenous communities have employed sustainable ecosystem management approaches implicitly for millennia, ecosystem management emerged explicitly as a formal concept in the 1990s from a growing appreciation of the complexity of ecosystems and of humans' reliance and influence on natural systems (e.
Game lawGame laws are statutes which regulate the right to pursue and hunt certain kinds of wild animals (games or quarries) and fish (although the latter often comes under the jurisdiction of fisheries law). The scope of game laws can include the following: Restricting the days to harvest fish or game (i.e. open and closed seasons); Restricting the number of animals per person; Restricting species, sex and age of animals allowed to be harvested; Restricting the region where hunting is allowed to take place, and; Limiting the weapons, gears and techniques that can be used.
PoachingPoaching is the illegal hunting or capturing of wild animals, usually associated with land use rights. Poaching was once performed by impoverished peasants for subsistence purposes and to supplement meager diets. It was set against the hunting privileges of nobility and territorial rulers. Since the 1980s, the term "poaching" has also been used to refer to the illegal harvesting of wild plants.
Game (hunting)Game or quarry is any wild animal hunted for animal products (primarily meat), for recreation ("sporting"), or for trophies. The species of animals hunted as game varies in different parts of the world and by different local jurisdictions, though most are terrestrial mammals and birds. Fish caught non-commercially (recreational fishing) are also referred to as game fish. The range of animal species hunted by humans varies in different parts of the world.

HuntingHunting is the human practice of seeking, pursuing, capturing, or killing wildlife or feral animals. The most common reasons for humans to hunt are to exploit the animal's body for food (i.e. meat) and useful animal products (fur/hide, bone/tusks, horn/antler, etc.), for recreation/taxidermy (see trophy hunting), although it may also be done for non-exploitative reasons such as removing predators dangerous to humans or domestic animals (e.g.
Environmental scienceEnvironmental science is an interdisciplinary academic field that integrates physics, biology, and geography (including ecology, chemistry, plant science, zoology, mineralogy, oceanography, limnology, soil science, geology and physical geography, and atmospheric science) to the study of the environment, and the solution of environmental problems. Environmental science emerged from the fields of natural history and medicine during the Enlightenment. Today it provides an integrated, quantitative, and interdisciplinary approach to the study of environmental systems.
Holocene extinctionThe Holocene extinction, or Anthropocene extinction, is the ongoing extinction event during the Holocene epoch. The extinctions span numerous families of plants and animals, including mammals, birds, reptiles, amphibians, fish, invertebrates, and affecting not just terrestrial species but also large sectors of marine life. With widespread degradation of biodiversity hotspots, such as coral reefs and rainforests, as well as other areas, the vast majority of these extinctions are thought to be undocumented, as the species are undiscovered at the time of their extinction, which goes unrecorded.
