Editing Extinction (section)

===== Disease agents =====
The [[poliovirus]] is now confined to small parts of the world due to extermination efforts.<ref name="polio">{{cite web |url=http://www.polioeradication.org/Dataandmonitoring.aspx |title=Polio cases in the world in 2015 |publisher=The Global Polio Eradication Initiative |access-date=17 February 2016 |archive-date=19 February 2016 |archive-url=https://web.archive.org/web/20160219015412/http://www.polioeradication.org/Dataandmonitoring.aspx |url-status=live}}</ref>

''[[Dracunculus medinensis]]'', or Guinea worm, a parasitic worm which causes the disease [[dracunculiasis]], is now close to eradication thanks to efforts led by the [[Carter Center]].<ref>{{cite magazine |url=https://time.com/3680439/guinea-worm-almost-extinct/ |title=This Species is Close to Extinction and That's a Good Thing |date=23 January 2015 |magazine=Time |access-date=17 February 2016 |archive-date=24 February 2016 |archive-url=https://web.archive.org/web/20160224032526/http://time.com/3680439/guinea-worm-almost-extinct/ |url-status=live}}</ref>

''[[Treponema pallidum|Treponema pallidum pertenue]]'', a bacterium which causes the disease [[yaws]], is in the process of being eradicated.

===== Disease vectors =====
Biologist [[Olivia Judson]] has advocated the deliberate extinction of certain disease-carrying [[mosquito]] species. In an article in ''[[The New York Times]]'' on 25 September 2003, she advocated "specicide" of thirty mosquito species by introducing a genetic element that can insert itself into another crucial gene, to create [[recessive]] "[[Gene knockout|knockout genes]]".<ref name="Judson"/> She says that the ''[[Anopheles]]'' mosquitoes (which spread [[malaria]]) and ''[[Aedes]]'' mosquitoes (which spread [[dengue fever]], [[yellow fever]], [[elephantiasis tropica|elephantiasis]], and other diseases) represent only 30 of around 3,500 mosquito species; eradicating these would save at least one million human lives per year, at a cost of reducing the [[genetic diversity]] of the family [[Culicidae]] by only 1%. She further argues that since species become extinct "all the time" the disappearance of a few more will not destroy the [[ecosystem]]: "We're not left with a wasteland every time a species vanishes. Removing one species sometimes causes shifts in the populations of other species—but different need not mean worse." In addition, anti-malarial and [[Mosquito#Control|mosquito control programs]] offer little realistic hope to the 300&nbsp;million people in [[developing nation]]s who will be infected with acute illnesses this year. Although trials are ongoing, she writes that if they fail "we should consider the ultimate swatting".<ref name="Judson">{{cite news |url=https://www.nytimes.com/2003/09/25/opinion/a-bug-s-death.html |title=A Bug's Death |date=September 25, 2003 |last=Judson |first=Olivia |author-link=Olivia Judson |newspaper=The New York Times |access-date=17 February 2016 |archive-date=6 March 2016 |archive-url=https://web.archive.org/web/20160306163542/http://www.nytimes.com/2003/09/25/opinion/a-bug-s-death.html |url-status=live}}</ref>

Biologist [[E. O. Wilson]] has advocated the eradication of several species of mosquito, including malaria vector ''[[Anopheles gambiae]]''. Wilson stated, "I'm talking about a very small number of species that have co-evolved with us and are preying on humans, so it would certainly be acceptable to remove them. I believe it's just common sense."<ref>{{cite news |last1=Paulson |first1=Steve |title=Why a famous biologist wants to eradicate killer mosquitoes |url=https://theworld.org/stories/2016-04-04/why-famous-biologist-wants-eradicate-killer-mosquitoes |work=The World from PRX |date=4 April 2016 |access-date=9 February 2022 |archive-date=9 February 2022 |archive-url=https://web.archive.org/web/20220209131520/https://theworld.org/stories/2016-04-04/why-famous-biologist-wants-eradicate-killer-mosquitoes |url-status=live}}</ref>

There have been many campaigns – some successful – to locally eradicate [[tsetse fly|tsetse flies]] and their [[trypanosoma|trypanosome]]s in areas, countries, and islands of Africa (including [[Príncipe]]).<ref name="Costa-et-al-1916">{{cite book |title=Sleeping Sickness, A Record of Four Years' War against It in the Island of Principe |first1=B.
