When the giant flightless birds called moa were overexploited to the point of extinction, [5] the giant Haast's eagle that preyed on them also became extinct. [6]The concern about overexploitation, while relatively recent in the annals of modern environmental awareness, traces back to ancient practices embedded in human history.
Extinction of species: Processes involved in resource exploitation can directly or indirectly lead to the extinction of species. [17] Animals used for resources can be directly hunted, while destruction of environments, such as through harvesting timber, can also cause extinctions. Forced migration; Soil erosion; Oil depletion [18] Ozone depletion
Jack mackerel caught by a Chilean purse seiner Fishing down the food web. Overfishing is the removal of a species of fish (i.e. fishing) from a body of water at a rate greater than that the species can replenish its population naturally (i.e. the overexploitation of the fishery's existing fish stock), resulting in the species becoming increasingly underpopulated in that area.
The main drivers of marine species extinction are habitat loss, pollution, invasive species, and overexploitation. [105] [106] Greater pressure is placed on marine ecosystems near coastal areas because of the human settlements in those areas. [107] Overexploitation has resulted in the extinction of over 25 marine species.
An example of how this may happen is through by-catch.These new species will outcompete the native species and take over, therefore causing the local or global extinction of a species. [32] Due to the fittest animals in the species being hunted or poached, the less fit organisms will mate, causing less fitness in the generations to come.
Marine conservation, also known as ocean conservation, is the protection and preservation of ecosystems in oceans and seas through planned management in order to prevent the over-exploitation of these marine resources.
PETA (People for the Ethical Treatment of Animals) ripped the Offspring due to its "egregious exploitation of chimpanzees" in the band's "We Never Have Sex Anymore" video. The animal rights ...
The term caught on; Singer wrote that it was an awkward word but that he could not think of a better one. It became an entry in the Oxford English Dictionary in 1985, defined as "discrimination against or exploitation of animal species by human beings, based on an assumption of mankind's superiority."
