====Indoor air pollution====
[[Indoor air pollution in developing nations]] is a major health hazard.<ref>{{cite journal | vauthors = Bruce N, Perez-Padilla R, Albalak R | title = Indoor air pollution in developing countries: a major environmental and public health challenge | journal = Bulletin of the World Health Organization | volume = 78 | issue = 9 | pages = 1078–92 | date = 2000 | pmid = 11019457 | pmc = 2560841 }}</ref> A major source of indoor air pollution in developing countries is the burning of [[biomass]]. Three billion people in developing countries across the globe rely on biomass in the form of wood, [[charcoal]], [[Manure|dung]], and [[crop residue]], as their domestic cooking fuel.<ref>{{cite journal|vauthors=Duflo E, Greenstone M, Hanna R|year=2008|title=Indoor air pollution, health and economic well-being|url=http://sapiens.revues.org/index130.html|journal=S.A.P.I.EN.S|volume=1|issue=1|access-date=30 April 2018|archive-date=10 January 2010|archive-url=https://web.archive.org/web/20100110102416/http://sapiens.revues.org/index130.html|url-status=live}}</ref> Because much of the cooking is carried out indoors in environments that lack proper ventilation, millions of people, primarily poor women and children face serious health risks.

Globally, 4.3 million deaths were attributed to exposure to IAP in developing countries in 2012, almost all in low and middle income countries. The South East Asian and Western Pacific regions bear most of the burden with 1.69 and 1.62 million deaths, respectively. Almost 600,000 deaths occur in Africa.<ref name="WHO1">{{cite web|title=Burden of disease from Indoor Air Pollution for 2012|url=https://www.who.int/phe/health_topics/outdoorair/databases/FINAL_HAP_AAP_BoD_24March2014.pdf?ua=1|publisher=WHO|access-date=28 March 2014|date=24 March 2014|archive-date=5 April 2022|archive-url=https://web.archive.org/web/20220405141320/https://www.who.int/phe/health_topics/outdoorair/databases/FINAL_HAP_AAP_BoD_24March2014.pdf?ua=1|url-status=live}}</ref> An earlier estimate from 2000 put the death toll between 1.5 million and 2 million deaths.<ref name="Ezzati">{{cite journal | vauthors = Ezzati M, Kammen DM | title = The health impacts of exposure to indoor air pollution from solid fuels in developing countries: knowledge, gaps, and data needs | journal = Environmental Health Perspectives | volume = 110 | issue = 11 | pages = 1057–68 | date = November 2002 | pmid = 12417475 | pmc = 1241060 | doi = 10.1289/ehp.021101057 | bibcode = 2002EnvHP.110.1057E }}</ref>

Finding an affordable solution to address the many effects of indoor air pollution is complex. Strategies include improving combustion, reducing smoke exposure, improving safety and reducing labor, reducing fuel costs, and addressing sustainability.<ref>{{cite journal |vauthors=Duflo E, Greenstone M, Hanna R |title=Indoor air pollution, health and economic well-being |journal=S.A.P.I.EN.S |volume=1 |issue=1 |year=2008 |url=http://sapiens.revues.org/index130.html |access-date=30 April 2018 |archive-date=10 January 2010 |archive-url=https://web.archive.org/web/20100110102416/http://sapiens.revues.org/index130.html |url-status=live }}</ref>
