An '''endangered species''' is a [[species]] that is very likely to become [[extinct]] in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as [[habitat loss]], [[poaching]], and [[invasive species]].<ref>{{Cite web |title=Why do animals and plants become endangered? {{!}} U.S. Geological Survey |url=https://www.usgs.gov/faqs/why-do-animals-and-plants-become-endangered |access-date=2024-01-14 |website=www.usgs.gov}}</ref> The [[International Union for Conservation of Nature]] (IUCN) [[IUCN Red List|Red List]] lists the global [[conservation status]] of many species, and various other agencies assess the status of species within particular areas. Many nations have [[Environmental law|law]]s that protect [[conservation-reliant species]] which, for example, forbid [[hunting]], restrict [[land development]], or create [[protected area]]s. Some endangered species are the target of extensive conservation efforts such as [[captive breeding]] and [[habitat restoration]].

The [[conservation status]] of a [[species]] indicates the likelihood that it will become [[extinct]]. Multiple factors are considered when assessing the status of a species; e.g., such statistics as the number remaining, the overall increase or decrease in the population over time, breeding success rates, or known threats.<ref>{{cite web |url=http://www.natureserve.org/infonatura/Lnsstatus.htm |title=NatureServe Conservation Status |date=April 2007 |publisher=NatureServe |access-date=2 June 2012 |archive-date=21 September 2013 |archive-url=https://web.archive.org/web/20130921055302/http://www.natureserve.org/infonatura/Lnsstatus.htm |url-status=live }}</ref> The [[IUCN Red List|IUCN Red List of Threatened Species]] is the best-known worldwide conservation status listing and ranking system.<ref>{{cite web|url=http://www.iucnredlist.org/about/red-list-overview |title=Red List Overview |date=February 2011 |publisher=IUCN |access-date=2 June 2012 |url-status=dead |archive-url=https://web.archive.org/web/20120527175928/http://www.iucnredlist.org/about/red-list-overview |archive-date=May 27, 2012 }}</ref>

Though labeled a list, the [[IUCN Red List]] is a system of assessing the global conservation status of species that includes "Data Deficient" (DD) species – species for which more data and assessment is required before their situation may be determined – as well species comprehensively assessed by the IUCN's species assessment process.<ref name=":0">{{Cite web |date=2018-02-07 |title=IUCN Red List of Threatened Species |url=https://www.iucn.org/resources/conservation-tools/iucn-red-list-threatened-species |access-date=2022-04-22 |website=IUCN |language=en}}</ref> The species under the index include: mammals, birds, amphibians, cycads, and corals. Those species of "[[Near-threatened species|Near Threatened]]" (NT) and "[[Least concern|Least Concern]]" (LC) status have been assessed and found to have relatively robust and healthy populations, though these may be in decline. Unlike their more general use elsewhere, the List uses the terms "endangered species" and "threatened species" with particular meanings: "Endangered" (EN) species lie between "[[Vulnerable species|Vulnerable]]" (VU) and "[[Critically Endangered species|Critically Endangered]]" (CR) species. In 2012, the IUCN Red List listed 3,079 animal and 2,655 plant species as endangered (EN) worldwide.<ref name=":0" />
== In Brazil ==
Brazil is one of the most [[Biodiversity|biodiverse]] countries in the world, if not the most. It houses not only the Amazon forest but the [[Atlantic Forest|Atlantic forest]], the savanna-like [[Cerrado]] among other [[Biomes in Brazil|biomes]].<ref>{{Cite web |date=2016-05-21 |title=The top 10 most biodiverse countries |url=https://news.mongabay.com/2016/05/top-10-biodiverse-countries/ |access-date=2022-12-03 |website=Mongabay Environmental News |language=en-US}}</ref> Due to the high density of some of its well-preserved rainforests, [[Wildlife smuggling|wildlife trafficking]], which along with deforestation is one of the biggest endangerment drivers in Brazil, has become a challenge. Brazil has a broad legal system meant to protect the environment, including its [[Constitution of Brazil|Constitution]],<ref>{{Cite web |date=2010 |title=Brazilian Constitution of 1988 - Article 23 "The Union, the states, the federal district and the municipalities, in common, have the power: [...] VI – to protect the environment and to fight pollution in any of its forms; VII – to preserve the forests, fauna and flora |url=https://www.oas.org/es/sla/ddi/docs/acceso_informacion_base_dc_leyes_pais_b_1_en.pdf |access-date= |website=OAS (Organization of American States)}}</ref> as well as several federal, state and local government agencies tasked with protecting the [[fauna]] and [[flora]], fining individuals or companies linked to [[environmental crime]]s and confiscating illegally taken wildlife. Though such agencies can collect their data, each system operates relatively on its own when it comes to wildlife trafficking. However, both the agencies and the [[Non-governmental organization|NGO]]'s working in Brazil agree that the birds account for about 80% of trafficked species in the country.<ref>{{Cite web |title=A máfia dos bichos: Muito além de reality, tráfico de animais no Brasil tira 38 milhões de bichos da mata por ano e gira R$ 3 bi |url=https://www.uol.com.br/ecoa/reportagens-especiais/trafico-no-brasil-tira-por-ano-35-milhoes-de-animais-da-floresta-e-gira-r-3-bilhoes/ |access-date=2022-12-03 |website=www.uol.com.br |language=pt-br}}</ref>
The relation between wildlife smuggling, other environment crimes under the Brazilian law such as [[deforestation]], and endangered species is particularly intricate and troubling since the rarer the animal or plant gets the most targeted and valuable they become in the [[black market]], which leads to more endangered species in its turn.<ref>{{Cite web |last=KKIENERM |title=Wildlife, Forest & Fisheries Crime Module 1 Key Issues: Implications of Wildlife Trafficking |url=https://www.unodc.org/e4j/en/wildlife-crime/module-1/key-issues/implications-of-wildlife-trafficking.html |access-date=2022-12-04 |website=www.unodc.org |language=en}}</ref>
Additionally, some environment experts and scientists point to the disbanding of environment agencies and the repeal of laws in Brazil under the [[presidency of Jair Bolsonaro]] as one of the reasons behind a surge in the number of endangered species.<ref>{{Cite web |last=Magazine |first=Hakai |title=In COVID's Shadow, Illegal Fishing Flourishes |url=https://hakaimagazine.com/news/in-covids-shadow-illegal-fishing-flourishes/ |access-date=2022-12-06 |website=Hakai Magazine |language=en}}</ref> In one occasion during his presidency some fines totaling US$3.1 billion on environment criminals were revoked and at least one fine (related to [[Illegal, unreported and unregulated fishing|illegal fishing]]) imposed on Bolsonaro himself was cancelled and the agent who fined him was [[Demotion|demoted]].<ref>{{Cite web |title=Ato do governo Bolsonaro deve anular até R$ 16 bilhões em multas ambientais |url=https://noticias.uol.com.br/meio-ambiente/ultimas-noticias/redacao/2022/09/20/ibama-multa-ambiental-eduardo-bim-governo-bolsonaro-notificacao-por-edital.htm |access-date=2022-12-04 |website=noticias.uol.com.br |language=pt-br}}</ref>
In the past, Brazil has successfully saved the endemic [[golden lion tamarin]] from [[extinction]]. Massive campaigns to raise awareness among people by NGO's and governments, which included printing depictions of the golden lion tamarin in the [[Brazilian real|20 reais Brazilian banknotes]] (still in circulation), are credited with getting the species out of the [[Critically Endangered|critically endangered]] animals list.<ref>{{Cite web |title=Mico-leão-dourado é "case" de sucesso para preservação, mas vê nova ameaça |url=https://www.uol.com.br/ecoa/ultimas-noticias/2020/06/05/mico-leao-dourado-e-case-de-sucesso-para-preservacao-mas-ve-nova-ameaca.htm |access-date=2022-12-04 |website=www.uol.com.br |language=pt-br}}</ref><ref>{{Cite web |date=2022-06-01 |title=How Brazil is working to save the rare lion tamarins of the Atlantic Forest |url=https://news.mongabay.com/2022/06/how-brazil-is-working-to-save-the-rare-lion-tamarins-of-the-atlantic-forest/ |access-date=2022-12-04 |website=Mongabay Environmental News |language=en-US}}</ref>
== In the United States ==
There is data from the United States that shows a correlation between human populations and threatened and endangered species. Using species data from the Database on the Economics and Management of Endangered Species (DEMES) database and the period that the [[Endangered Species Act of 1973|Endangered Species Act]] (ESA) has been in existence, 1970 to 1997, a table was created that suggests a positive relationship between human activity and species endangerment.<ref>{{cite book|editor1-last=Shogren|editor1-first=Jason F.|editor2-last=Tschirhart|editor2-first=John |title=Protecting Endangered Species in the United States: Biological Needs, Political Realities, Economic Choices|year=2001 |url=https://archive.org/details/protectingendang00shog|url-access=limited|publisher=Cambridge University Press|isbn=0521662109|pages=[https://archive.org/details/protectingendang00shog/page/n25 1]}}</ref>
'''Impact of Climate Change on Endangered Species'''
Carbon dioxide in our atmosphere is asserted to be one of the leading cause of animal endangerment. <blockquote>"If we can sufficiently reduce greenhouse gas emissions, many of them will still have a chance to survive and recover". NASA scientist James Hanson has warned that in order to maintain a climate similar to that under which human civilization developed and similar to that which so many organisms are adapted, we need to quickly reduce the carbon dioxide in our atmosphere to 350 parts per million (ppm). Before the industrial revolution, atmospheric carbon dioxide levels rarely rose above 280 ppm; during the 2014 calendar year, carbon dioxide levels fluctuated between 395 and 402" - US National Park Service.<ref>{{cite web |url=https://www.nps.gov/pore/learn/nature/climatechange_wildlife.htm#:~:text=Biologists%20are%20becoming%20more%20and,due%20to%20global%20climate%20change. |title=Climate Change Endangers Wildlife |access-date=14 September 2023 |publisher=US National Park Service |date=25 March 2020 }}</ref></blockquote>

===Endangered Species Act===
Under the [[Endangered Species Act of 1973]] in the United States, species may be listed as "endangered" or "threatened". The [[Salt Creek tiger beetle]] (''Cicindela nevadica lincolniana'') is an example of an endangered subspecies protected under the ESA. The [[US Fish and Wildlife Service]], as well as the [[National Marine Fisheries Service]] are held responsible for classifying and protecting endangered species. They are also responsible for adding a particular species to the list, which can be a long, controversial process.<ref>{{cite journal |last1=Wilcove |first1=D.S. |last2=Master |first2=L.L. |title=How Many Endangered Species are there in the United States? |journal=Frontiers in Ecology and the Environment |date=2005 |volume=3 |issue=8 |page=414 |doi=10.2307/3868657 |jstor=3868657 |url=https://www.jstor.org/stable/3868657 |access-date=2021-06-01 |archive-date=2021-06-02 |archive-url=https://web.archive.org/web/20210602231055/https://www.jstor.org/stable/3868657 |url-status=live }}</ref>
Some endangered species laws are controversial. Typical areas of controversy include criteria for placing a species on the endangered species list and rules for removing a species from the list once its population has recovered. Whether restrictions on land development constitute a "taking" of land by the [[government]]; the related question of whether private landowners should be compensated for the loss of uses of their areas; and obtaining reasonable exceptions to protection laws. Also lobbying from [[hunting|hunters]] and various industries like the [[petroleum industry]], [[construction]] industry, and [[logging]], has been an obstacle in establishing endangered species laws.
The [[Presidency of George W. Bush|Bush administration]] lifted a policy that required federal officials to consult a wildlife expert before taking actions that could damage endangered species. Under the [[Obama administration]], this policy was reinstated.<ref>{{Cite web|date=2009-03-03|title=Reversing Bush Rule, Obama Resumes Safeguards for Endangered Species|url=https://www.pbs.org/newshour/science/science-jan-june09-speciesrule_03-03|access-date=2021-07-23|website=PBS NewsHour|language=en-us|archive-date=2019-09-03|archive-url=https://web.archive.org/web/20190903123529/https://www.pbs.org/newshour/science/science-jan-june09-speciesrule_03-03|url-status=live}}</ref>
Being listed as an endangered species can have negative effect since it could make a species more desirable for collectors and poachers.<ref>{{cite journal |last=Courchamp |first=Franck |author2=Elena Angulo |author3=Philippe Rivalan |author4=Richard J. Hall |author5=Laetitia Signoret |author6=Leigh Bull |author7=Yves Meinard |title=Rarity Value and Species Extinction: The Anthropogenic Allee Effect |journal=PLOS Biology |volume=4 |issue=12 |pages=e415 |doi=10.1371/journal.pbio.0040415 |pmid=17132047 |pmc=1661683 |year=2006 |doi-access=free }}</ref> This effect is potentially reducible, such as in China where commercially farmed turtles may be reducing some of the pressure to poach endangered species.<ref>{{cite journal |last=Dharmananda |first=Subhuti |title=Endangered Species issues affecting turtles and tortoises used in Chinese medicine |journal=PLOS Biology |volume=4 |issue=12 |pages=e415 |publisher=Institute for Traditional Medicine, Portland, Oregon |doi=10.1371/journal.pbio.0040415 |pmid=17132047 |pmc=1661683 |year=2006 |doi-access=free }}</ref>
Another problem with the listing species is its effect of inciting the use of the "shoot, shovel, and shut-up" method of clearing endangered species from an area of land. Some landowners currently may perceive a diminution in value for their land after finding an endangered animal on it. They have allegedly opted to kill and bury the animals or destroy habitat silently. Thus removing the problem from their land, but at the same time further reducing the population of an endangered species.<ref>{{cite web |url=http://www.reason.com/news/show/34933.html |title=Shoot, Shovel and Shut Up |work=Reasononline |publisher=Reason Magazine |date=2003-12-31 |access-date=2006-12-23 |archive-url=https://web.archive.org/web/20090921131035/http://www.reason.com/news/show/34933.html |archive-date=2009-09-21 |url-status=dead }}</ref> The effectiveness of the [[Endangered Species Act of 1973|Endangered Species Act]] – which coined the term "endangered species" – has been questioned by business advocacy groups and their publications but is nevertheless widely recognized by wildlife scientists who work with the species as an effective recovery tool.

Currently, 1,556 endangered species are under protection by government law. This approximation, however, does not take into consideration the species threatened with endangerment that are not included under the protection of laws like the Endangered Species Act. According to [[NatureServe conservation status|NatureServe's global conservation status]], approximately thirteen percent of vertebrates (excluding marine fish), seventeen percent of vascular plants, and six to eighteen percent of fungi are considered imperiled.<ref name="WM2005">Wilcove & Master 2005.</ref>{{refpages|415|16}} Thus, in total, between seven and eighteen percent of the United States' known animals, fungi and plants are near extinction.<ref name="WM2005" />{{refpage|416}} This total is substantially more than the number of species protected in the United States under the Endangered Species Act.

Ever since humankind began hunting to preserve itself, over-hunting and fishing have been a large and dangerous problem. Of all the species who became extinct due to interference from humankind, the [[dodo]], [[passenger pigeon]], [[great auk]], [[Tasmanian tiger]] and [[Steller's sea cow]] are some of the more well known examples; with the [[bald eagle]], [[grizzly bear]], [[American bison]], [[Eastern timber wolf]] and [[sea turtle]] having been poached to near-extinction. Many began as food sources seen as necessary for survival but became the target of sport. However, due to major efforts to prevent extinction, the bald eagle, or ''[[Bald eagle|Haliaeetus leucocephalus]]'' is now under the category of Least Concern on the red list.<ref>{{cite iucn |author=BirdLife International |date=2016 |title=''Haliaeetus leucocephalus'' |volume=2016 |page=e.T22695144A93492523 |doi=10.2305/IUCN.UK.2016-3.RLTS.T22695144A93492523.en |access-date=11 November 2021}}</ref> A present-day example of the over-hunting of a species can be seen in the oceans as populations of certain whales have been greatly reduced.

Actions have been taken to attempt a reduction in whaling and increase population sizes. The actions include prohibiting all whaling in United States waters, the formation of the CITES treaty which protects all whales, along with the formation of the [[International Whaling Commission|International Whaling Commission (IWC)]]. But even though all of these movements have been put in place, countries such as [[Japan]] continue to hunt and harvest whales under the claim of "scientific purposes".<ref>{{cite journal |last=Freedman |first=Bill |title=Endangered species |journal=Gale |volume=46 |issue=44 |pages=25 |year=2008 |edition=4th|pmid=30399289 }}</ref> Over-hunting, climatic change and habitat loss leads in landing species in endangered species list.

== In Canada ==
Endangered species are addressed through Canada's [[Species at Risk Act]]. A species is deemed threatened or endangered when it is on the verge of extinction or [[Local extinction|extirpation]]. Once a species is deemed threatened or endangered, the Act requires that a recovery plan to be developed that indicates how to stop or reverse the species' population decline.<ref>{{Cite web |last=Canada |first=Environment and Climate Change |date=2018-02-26 |title=Species at Risk Act: recovery strategies |url=https://www.canada.ca/en/environment-climate-change/services/species-risk-public-registry/recovery-strategies.html |access-date=2022-08-01 |website=www.canada.ca}}</ref> As of 2021, the [[Committee on the Status of Endangered Wildlife in Canada|Committee on the Status of Endangered Wildlife In Canada]] (COSEWIC) has assessed 369 species as being endangered in Canada.

== Invasive species ==
{{Main|Introduced species}}
The introduction of non-indigenous species to an area can disrupt the ecosystem to such an extent that native species become endangered. Such introductions may be termed alien or invasive species. In some cases, the invasive species compete with the native species for food or prey on the natives. In other cases, a stable ecological balance may be upset by predation or other causes leading to unexpected species decline. New species may also carry diseases to which the native species have no exposure or resistance.<ref>{{cite journal |last=Chiras |first=Daniel D. |title=Invader Species |url=http://www.scholastic.com/browse/article.jsp?id=3753825 |journal=Grolier |year=2011 |series=Online |access-date=2015-03-04 |archive-date=2018-10-09 |archive-url=https://web.archive.org/web/20181009013252/http://www.scholastic.com/browse/article.jsp?id=3753825 |url-status=dead }}</ref>
== Climate change ==
[[The World Wildlife Fund]] (WWF) emphasizes that our planet is warming at a rate faster than any time in the past 10,000 years, necessitating species to adapt to new climate patterns, such as variations in rainfall and longer, warmer summers.<ref name=":1">{{Cite web |title=Impact of climate change on species |url=https://wwf.panda.org/discover/our_focus/wildlife_practice/problems/climate_change/ |access-date=2024-02-03 |website=wwf.panda.org |language=en}}</ref> For example, the [[United States Fish and Wildlife Service|U.S. Fish & Wildlife Service]] highlighted efforts to understand and mitigate the impact of climate change on species through scientific research, modeling, and conservation actions. This includes evaluating the current condition of species, their genetic variation, and how changes in their environment may affect their survival.<ref>{{Cite web |date=2024-01-04 |title=Protecting threatened and endangered species in a changing climate {{!}} U.S. Fish & Wildlife Service |url=https://www.fws.gov/story/2024-01/protecting-threatened-and-endangered-species-changing-climate |access-date=2024-02-03 |website=www.fws.gov |language=en}}</ref>
The [[International Union for Conservation of Nature]] (IUCN) reports that the approximately 1°C rise in mean global temperature due to human activities is causing serious impacts on species, including changes in abundance, genetic composition, behavior, and survival. The IUCN stresses the importance of environmental policies aimed at reducing CO2 emissions to lessen the impact of climate change on species. Tools like the IUCN Red List and guidelines for assessing species' vulnerability to climate change are vital for conservation efforts.<ref>{{Cite web |title=Species and climate change |url=https://www.iucn.org/resources/issues-brief/species-and-climate-change |access-date=2024-02-03 |website=www.iucn.org |language=en}}</ref>
In addition, climate change can lead to species disappearing from areas where they once thrived, or even going extinct. A study cited by WWF found that one in six species is at risk of extinction due to climate change if no action is taken. The phenomenon of species shifting their ranges in response to changing climates, finding new or shrinking habitats, illustrates the direct impact of global warming on biodiversity.<ref name=":1" />
For example the [[Emperor penguin|Emperor Penguins]], which rely on Antarctic sea ice for breeding, shelter, and food. The melting of ice sheets poses a direct threat to their survival. Similarly, the Mount Rainier [[white-tailed ptarmigan]], adapted to alpine mountaintops, faces habitat loss due to climate changes in snowfall patterns and rising temperatures. <ref>{{Cite web |date=2022-05-26 |title=Preventing Extinctions in a Changing Climate {{!}} U.S. Fish & Wildlife Service |url=https://www.fws.gov/story/2022-05/preventing-extinctions-changing-climate |access-date=2024-02-03 |website=www.fws.gov |language=en}}</ref>

===Captive breeding===
{{Main|Captive breeding}}
Captive breeding is the process of breeding rare or endangered species in human controlled environments with restricted settings, such as wildlife reserves, zoos, and other conservation facilities. Captive breeding is meant to save species from extinction and so stabilise the population of the species that it will not disappear.<ref>{{cite web |url=http://nationalzoo.si.edu/ConservationAndScience/EndangeredSpecies/CapBreedPops/default.cfm |title=Captive Breeding Populations – National Zoo |publisher=Nationalzoo.si.edu |access-date=2009-12-06 |archive-date=2009-10-15 |archive-url=https://web.archive.org/web/20091015180848/http://nationalzoo.si.edu/ConservationAndScience/EndangeredSpecies/CapBreedPops/default.cfm |url-status=live }}</ref>
This technique has worked for many species for some time, with probably the oldest known such instances of captive mating being attributed to menageries of European and Asian rulers, an example being the [[Père David's deer]]. However, captive breeding techniques are usually difficult to implement for such highly mobile species as some migratory birds (e.g. cranes) and fishes (e.g. [[hilsa]]). Additionally, if the captive breeding population is too small, then inbreeding may occur due to a reduced [[gene pool]] and reduce [[immunity (medical)|resistance]].[[File:Status ESA LE.svg|upright=1.1|left|thumb|"Endangered" in relation to "threatened" under the ESA]]In 1981, the [[Association of Zoos and Aquariums]] (AZA) created a [[Species Survival Plan]] (SSP) to help preserve specific endangered and threatened species through captive breeding. With over 450 SSP Plans, some endangered species are covered by the AZA with plans to cover population management goals and recommendations for breeding for a diverse and healthy population, created by Taxon Advisory Groups. These programs are commonly created as a last resort effort. SSP Programs regularly participate in species recovery, veterinary care for wildlife disease outbreaks, and some other wildlife conservation efforts. The AZA's Species Survival Plan also has breeding and transfer programs, both within and outside of AZA – certified zoos and aquariums. Some animals that are part of SSP programs are [[giant pandas]], lowland gorillas, and [[California condors]].<ref>{{Cite web|url =https://www.aza.org/species-survival-plan-program/|archive-url =https://wayback.archive-it.org/all/20090803071836/http://www.aza.org/species-survival-plan-program/|url-status =dead|archive-date =2009-08-03|title =Association of Zoos and Aquariums Species Survival Programs}}</ref>
===Private farming===
[[File:Ostafrikanisches Spitzmaulnashorn.JPG|thumb|upright=0.7|Black rhino]]
[[File:Thmac u0.gif|thumb|upright=0.7|[[Southern bluefin tuna]]]]
Whereas poaching substantially reduces endangered animal populations, legal, for-profit, private farming does the opposite. It has substantially increased the populations of the southern [[black rhinoceros]] and southern [[white rhinoceros]]. Richard Emslie, a scientific officer at the IUCN, said of such programs, "Effective law enforcement has become much easier now that the animals are largely privately owned... We have been able to bring local communities into conservation programs. There are increasingly strong economic incentives attached to looking after rhinos rather than simply poaching: from Eco-tourism or selling them on for a profit. So many owners are keeping them secure. The private sector has been key to helping our work."<ref>"[https://www.independent.co.uk/environment/nature/hes-black-and-hes-back-private-enterprise-saves-southern-africas-rhino-from-extinction-848482.html He's black, and he's back!

-'''Impact of Climate Change on Endangered Species'''
-
-Carbon dioxide in our atmosphere is asserted to be one of the leading cause of animal endangerment. <blockquote>"If we can sufficiently reduce greenhouse gas emissions, many of them will still have a chance to survive and recover". NASA scientist James Hanson has warned that in order to maintain a climate similar to that under which human civilization developed and similar to that which so many organisms are adapted, we need to quickly reduce the carbon dioxide in our atmosphere to 350 parts per million (ppm). Before the industrial revolution, atmospheric carbon dioxide levels rarely rose above 280 ppm; during the 2014 calendar year, carbon dioxide levels fluctuated between 395 and 402" - US National Park Service.<ref>{{cite web |url=https://www.nps.gov/pore/learn/nature/climatechange_wildlife.htm#:~:text=Biologists%20are%20becoming%20more%20and,due%20to%20global%20climate%20change. |title=Climate Change Endangers Wildlife |access-date=14 September 2023 |publisher=US National Park Service |date=25 March 2020 }}</ref></blockquote>

-===Endangered Species Act===
-Under the [[Endangered Species Act of 1973]] in the United States, species may be listed as "endangered" or "threatened". The [[Salt Creek tiger beetle]] (''Cicindela nevadica lincolniana'') is an example of an endangered subspecies protected under the ESA. The [[US Fish and Wildlife Service]], as well as the [[National Marine Fisheries Service]] are held responsible for classifying and protecting endangered species. They are also responsible for adding a particular species to the list, which can be a long, controversial process.<ref>{{cite journal |last1=Wilcove |first1=D.S. |last2=Master |first2=L.L. |title=How Many Endangered Species are there in the United States? |journal=Frontiers in Ecology and the Environment |date=2005 |volume=3 |issue=8 |page=414 |doi=10.2307/3868657 |jstor=3868657 |url=https://www.jstor.org/stable/3868657 |access-date=2021-06-01 |archive-date=2021-06-02 |archive-url=https://web.archive.org/web/20210602231055/https://www.jstor.org/stable/3868657 |url-status=live }}</ref>
-
-Some endangered species laws are controversial. Typical areas of controversy include criteria for placing a species on the endangered species list and rules for removing a species from the list once its population has recovered. Whether restrictions on land development constitute a "taking" of land by the [[government]]; the related question of whether private landowners should be compensated for the loss of uses of their areas; and obtaining reasonable exceptions to protection laws. Also lobbying from [[hunting|hunters]] and various industries like the [[petroleum industry]], [[construction]] industry, and [[logging]], has been an obstacle in establishing endangered species laws.
-
-The [[Presidency of George W. Bush|Bush administration]] lifted a policy that required federal officials to consult a wildlife expert before taking actions that could damage endangered species. Under the [[Obama administration]], this policy was reinstated.<ref>{{Cite web|date=2009-03-03|title=Reversing Bush Rule, Obama Resumes Safeguards for Endangered Species|url=https://www.pbs.org/newshour/science/science-jan-june09-speciesrule_03-03|access-date=2021-07-23|website=PBS NewsHour|language=en-us|archive-date=2019-09-03|archive-url=https://web.archive.org/web/20190903123529/https://www.pbs.org/newshour/science/science-jan-june09-speciesrule_03-03|url-status=live}}</ref>

-Another problem with the listing species is its effect of inciting the use of the "shoot, shovel, and shut-up" method of clearing endangered species from an area of land. Some landowners currently may perceive a diminution in value for their land after finding an endangered animal on it. They have allegedly opted to kill and bury the animals or destroy habitat silently. Thus removing the problem from their land, but at the same time further reducing the population of an endangered species.<ref>{{cite web |url=http://www.reason.com/news/show/34933.html |title=Shoot, Shovel and Shut Up |work=Reasononline |publisher=Reason Magazine |date=2003-12-31 |access-date=2006-12-23 |archive-url=https://web.archive.org/web/20090921131035/http://www.reason.com/news/show/34933.html |archive-date=2009-09-21 |url-status=dead }}</ref> The effectiveness of the [[Endangered Species Act of 1973|Endangered Species Act]] – which coined the term "endangered species" – has been questioned by business advocacy groups and their publications but is nevertheless widely recognized by wildlife scientists who work with the species as an effective recovery tool.

-Currently, 1,556 endangered species are under protection by government law. This approximation, however, does not take into consideration the species threatened with endangerment that are not included under the protection of laws like the Endangered Species Act. According to [[NatureServe conservation status|NatureServe's global conservation status]], approximately thirteen percent of vertebrates (excluding marine fish), seventeen percent of vascular plants, and six to eighteen percent of fungi are considered imperiled.<ref name="WM2005">Wilcove & Master 2005.</ref>{{refpages|415|16}} Thus, in total, between seven and eighteen percent of the United States' known animals, fungi and plants are near extinction.<ref name="WM2005" />{{refpage|416}} This total is substantially more than the number of species protected in the United States under the Endangered Species Act.

The actions include prohibiting all whaling in United States waters, the formation of the CITES treaty which protects all whales, along with the formation of the [[International Whaling Commission|International Whaling Commission (IWC)]]. But even though all of these movements have been put in place, countries such as [[Japan]] continue to hunt and harvest whales under the claim of "scientific purposes".<ref>{{cite journal |last=Freedman |first=Bill |title=Endangered species |journal=Gale |volume=46 |issue=44 |pages=25 |year=2008 |edition=4th|pmid=30399289 }}</ref> Over-hunting, climatic change and habitat loss leads in landing species in endangered species list.

-== Invasive species ==
-{{Main|Introduced species}}
-
-The introduction of non-indigenous species to an area can disrupt the ecosystem to such an extent that native species become endangered. Such introductions may be termed alien or invasive species. In some cases, the invasive species compete with the native species for food or prey on the natives. In other cases, a stable ecological balance may be upset by predation or other causes leading to unexpected species decline. New species may also carry diseases to which the native species have no exposure or resistance.<ref>{{cite journal |last=Chiras |first=Daniel D. |title=Invader Species |url=http://www.scholastic.com/browse/article.jsp?id=3753825 |journal=Grolier |year=2011 |series=Online |access-date=2015-03-04 |archive-date=2018-10-09 |archive-url=https://web.archive.org/web/20181009013252/http://www.scholastic.com/browse/article.jsp?id=3753825 |url-status=dead }}</ref>

-== Climate change ==
-[[The World Wildlife Fund]] (WWF) emphasizes that our planet is warming at a rate faster than any time in the past 10,000 years, necessitating species to adapt to new climate patterns, such as variations in rainfall and longer, warmer summers.<ref name=":1">{{Cite web |title=Impact of climate change on species |url=https://wwf.panda.org/discover/our_focus/wildlife_practice/problems/climate_change/ |access-date=2024-02-03 |website=wwf.panda.org |language=en}}</ref> For example, the [[United States Fish and Wildlife Service|U.S. Fish & Wildlife Service]] highlighted efforts to understand and mitigate the impact of climate change on species through scientific research, modeling, and conservation actions. This includes evaluating the current condition of species, their genetic variation, and how changes in their environment may affect their survival.<ref>{{Cite web |date=2024-01-04 |title=Protecting threatened and endangered species in a changing climate {{!}} U.S. Fish & Wildlife Service |url=https://www.fws.gov/story/2024-01/protecting-threatened-and-endangered-species-changing-climate |access-date=2024-02-03 |website=www.fws.gov |language=en}}</ref>
-
-The [[International Union for Conservation of Nature]] (IUCN) reports that the approximately 1°C rise in mean global temperature due to human activities is causing serious impacts on species, including changes in abundance, genetic composition, behavior, and survival. The IUCN stresses the importance of environmental policies aimed at reducing CO2 emissions to lessen the impact of climate change on species. Tools like the IUCN Red List and guidelines for assessing species' vulnerability to climate change are vital for conservation efforts.<ref>{{Cite web |title=Species and climate change |url=https://www.iucn.org/resources/issues-brief/species-and-climate-change |access-date=2024-02-03 |website=www.iucn.org |language=en}}</ref>
-
-In addition, climate change can lead to species disappearing from areas where they once thrived, or even going extinct. A study cited by WWF found that one in six species is at risk of extinction due to climate change if no action is taken. The phenomenon of species shifting their ranges in response to changing climates, finding new or shrinking habitats, illustrates the direct impact of global warming on biodiversity.<ref name=":1" />

-For example the [[Emperor penguin|Emperor Penguins]], which rely on Antarctic sea ice for breeding, shelter, and food. The melting of ice sheets poses a direct threat to their survival. Similarly, the Mount Rainier [[white-tailed ptarmigan]], adapted to alpine mountaintops, faces habitat loss due to climate changes in snowfall patterns and rising temperatures. <ref>{{Cite web |date=2022-05-26 |title=Preventing Extinctions in a Changing Climate {{!}} U.S. Fish & Wildlife Service |url=https://www.fws.gov/story/2022-05/preventing-extinctions-changing-climate |access-date=2024-02-03 |website=www.fws.gov |language=en}}</ref>

-===Captive breeding===
-{{Main|Captive breeding}}
-
-Captive breeding is the process of breeding rare or endangered species in human controlled environments with restricted settings, such as wildlife reserves, zoos, and other conservation facilities. Captive breeding is meant to save species from extinction and so stabilise the population of the species that it will not disappear.<ref>{{cite web |url=http://nationalzoo.si.edu/ConservationAndScience/EndangeredSpecies/CapBreedPops/default.cfm |title=Captive Breeding Populations – National Zoo |publisher=Nationalzoo.si.edu |access-date=2009-12-06 |archive-date=2009-10-15 |archive-url=https://web.archive.org/web/20091015180848/http://nationalzoo.si.edu/ConservationAndScience/EndangeredSpecies/CapBreedPops/default.cfm |url-status=live }}</ref>
-
-This technique has worked for many species for some time, with probably the oldest known such instances of captive mating being attributed to menageries of European and Asian rulers, an example being the [[Père David's deer]]. However, captive breeding techniques are usually difficult to implement for such highly mobile species as some migratory birds (e.g. cranes) and fishes (e.g. [[hilsa]]). Additionally, if the captive breeding population is too small, then inbreeding may occur due to a reduced [[gene pool]] and reduce [[immunity (medical)|resistance]].[[File:Status ESA LE.svg|upright=1.1|left|thumb|"Endangered" in relation to "threatened" under the ESA]]In 1981, the [[Association of Zoos and Aquariums]] (AZA) created a [[Species Survival Plan]] (SSP) to help preserve specific endangered and threatened species through captive breeding. With over 450 SSP Plans, some endangered species are covered by the AZA with plans to cover population management goals and recommendations for breeding for a diverse and healthy population, created by Taxon Advisory Groups. These programs are commonly created as a last resort effort. SSP Programs regularly participate in species recovery, veterinary care for wildlife disease outbreaks, and some other wildlife conservation efforts. The AZA's Species Survival Plan also has breeding and transfer programs, both within and outside of AZA – certified zoos and aquariums. Some animals that are part of SSP programs are [[giant pandas]], lowland gorillas, and [[California condors]].<ref>{{Cite web|url =https://www.aza.org/species-survival-plan-program/|archive-url =https://wayback.archive-it.org/all/20090803071836/http://www.aza.org/species-survival-plan-program/|url-status =dead|archive-date =2009-08-03|title =Association of Zoos and Aquariums Species Survival Programs}}</ref>

-Whereas poaching substantially reduces endangered animal populations, legal, for-profit, private farming does the opposite. It has substantially increased the populations of the southern [[black rhinoceros]] and southern [[white rhinoceros]]. Richard Emslie, a scientific officer at the IUCN, said of such programs, "Effective law enforcement has become much easier now that the animals are largely privately owned... We have been able to bring local communities into conservation programs. There are increasingly strong economic incentives attached to looking after rhinos rather than simply poaching: from Eco-tourism or selling them on for a profit. So many owners are keeping them secure.
