Us Children: Victims Of Air Pollution Fatalities

Air pollution is a significant global health concern, causing approximately 8.1 million deaths worldwide in 2021. It is the second-leading risk factor for death, surpassing tobacco use and poor diet. While air pollution impacts people of all ages, children under five are particularly vulnerable. According to a 2024 report, almost 2,000 children under five die daily due to air pollution, with malnutrition being the only higher risk factor for mortality in this age group. This issue is more prevalent in low- and middle-income countries, with Africa and Asia experiencing the highest death rates. The primary sources of air pollution contributing to these deaths include household combustion devices, motor vehicles, industrial activities, and forest fires, leading to increased respiratory and other health issues.

Global deaths of children under five due to air pollution

Air pollution is a significant threat to children's health and is the biggest environmental health risk factor. In 2021, it was the second leading risk factor for death among children under five globally, after malnutrition. According to the 2024 State of Global Air report, air pollution was linked to a total of 709,000 deaths in children under five, representing about 15% of all global deaths in this age group. This means that almost 2,000 children under five die every day due to health issues linked to air pollution. UNICEF's analysis of global air pollution and child health impact data from 2000 to 2021 revealed that in East Asia and the Pacific, air pollution is linked to more than 100 deaths in children under five every day.

Household air pollution, caused by burning solid fuels for cooking and heating, accounts for most pollution-linked deaths in children. In 2021, an estimated 2.3 billion people, about 30% of the global population, relied on polluting fuels and technologies for cooking, generating harmful household air pollution. More than 70% of air pollution-related deaths among children under five are linked to household air pollution. In addition, ambient PM2.5, which comes from emissions from power plants, transportation, industries, waste combustion, and other sources, also contributes to air pollution-related deaths.

Children under five face special risks from air pollution due to their developing organs and immature immune systems. They inhale more polluted air than adults, and this polluted air affects their health differently due to their immature lungs, brains, and other organs. The health effects of air pollution on children include premature birth, low birth weight, asthma, lung diseases, developmental delays, and an increased risk of serious health problems such as pneumonia, which accounts for 22% of all deaths in children between one and five years of age.

UNICEF is working to protect children from the devastating effects of air pollution by partnering with governments, businesses, health systems, and communities. Initiatives include advocating for climate and environmental policies, implementing programs to reduce children's exposure to household air pollution, improving air quality monitoring, strengthening healthcare systems, and collaborating with communities to raise awareness and push for stronger policies.

Air pollution sources

According to a report by UNICEF, almost 2,000 children under five years of age die every day due to health issues linked to air pollution. This figure corresponds to a total of 700,000 children under five dying annually from air pollution.

Mobile sources, such as vehicles, are a significant contributor to air pollution. This includes cars, trucks, trains, construction equipment, boats, and snowmobiles. The federal government has played a crucial role in reducing vehicle emissions by regulating car manufacturing and fuel production. For example, the removal of lead from gasoline and the reduction of sulfur in diesel fuel have drastically reduced pollutant levels in the air. Additionally, older diesel engines have been found to produce significantly more fine particulate pollution than newer models, emphasizing the importance of transitioning to more efficient and environmentally friendly vehicles.

Stationary sources, like power plants, are another major source of air pollution. These facilities emit large quantities of pollutants from a single location, also known as point sources. Coal-fired power plants, in particular, have been associated with high levels of mercury emissions and haze-forming pollutants. However, regulatory efforts such as the Minnesota Mercury Emissions Reduction Act have successfully reduced mercury emissions by 90% and significantly lowered greenhouse gas emissions.

Area sources, while consisting of smaller individual contributors, collectively play a significant role in air pollution. This includes neighborhood sources such as local businesses, heating and cooling equipment, wood fires, and gas-powered yard equipment. Residential wood burning has been increasing over time, with home heating and recreational fires as the primary reasons. In Minnesota, residential wood burning accounted for 55% of the state's direct fine particle emissions.

Air pollution in the US

Air pollution is a severe issue in the United States, with far-reaching health implications for its citizens, especially children. According to the World Health Organization (WHO), air pollution is a mixture of outdoor and indoor air pollution, caused by biological, chemical, or physical agents that modify the natural characteristics of the atmosphere. This includes household combustion devices, motor vehicles, industrial facilities, and forest fires.

In 2021, air pollution was responsible for an estimated 8.1 million deaths globally, with children under five being a vulnerable demographic. While the number of deaths in the US is not specified, it is part of the global statistics, and the issue of air pollution is prevalent in the country. The State of Global Air report, published by the Health Effects Institute (HEI) in collaboration with UNICEF, revealed that nearly every person breathes unhealthy levels of air pollution daily, with children in low-income countries suffering the worst impacts.

In the US, air pollution is a significant concern, especially in densely populated urban areas. Traffic exhaust, for example, is a major source of nitrogen dioxide (NO2), which has detrimental health effects, particularly on the development of childhood asthma. The impact of air pollution on children's health in the US is evident, with UNICEF USA reporting that air pollution is the second-leading cause of death for children under five, surpassed only by malnutrition.

While the US has made progress in reducing air pollution, it still faces challenges. The climate crisis, for instance, is worsening air quality, and higher temperatures can increase the impact of airborne pollutants like nitrogen oxides, which can transform into ozone, an irritant gas. Additionally, the US has historically struggled with air pollution, and while emissions of local air pollutants have decreased significantly, the issue remains a pressing concern.

To address air pollution in the US, various interventions and initiatives have been implemented. The WHO, for instance, has developed strategies to raise awareness about the risks of air pollution and promote solutions to mitigate exposure. Additionally, policies supporting sustainable land use, cleaner energy and transport, energy-efficient housing, and improved waste management can effectively reduce ambient air pollution.

Air pollution and climate change

Air pollution is a leading cause of death for children under five, second only to malnutrition. According to a 2024 report by the HEI, nearly 2,000 children under five die every day due to air pollution, with children in low-income countries suffering the worst impacts. The report also highlights the vast inequalities in air quality between high- and low-income countries, with the death rate linked to air pollution in children under five being 100 times higher in most of Africa than in wealthy nations.

The primary sources of air pollution include the use of fossil fuels for power generation, industry, and transport, which are also major sources of CO2 emissions. The burning of fossil fuels in these sectors results in the emission of particulate matter, such as black carbon, a significant contributor to global warming and climate change. In addition to outdoor air pollution, indoor air pollution from residential energy use, primarily heating and cooking, also significantly impacts premature mortality, particularly in developing countries where cookstoves emit black carbon.

Climate change and air pollution are closely interconnected, with certain air pollutants, such as black carbon and methane, contributing to climate change while also adversely affecting human health. The impacts of climate change, such as rising temperatures, prolonged droughts, and increased carbon dioxide concentrations, can worsen air quality by increasing ground-level ozone, pollen, and particulate matter. Wildfires, which are becoming more frequent and severe due to climate change, release smoke and particulate matter that reduce air quality and harm human health.

Regulatory initiatives, partnership programs, and individual actions can help reduce air pollutants and greenhouse gas emissions, improving both air quality and climate change mitigation. Phasing out fossil fuels and transitioning to clean energy sources offer a "win-win" strategy, improving public health and reducing emissions that contribute to global warming.

While I could not find specific data on the number of US children who die annually from air pollution, the HEI report and other sources highlight the severe impact of air pollution on children's health, with thousands of children dying prematurely each year worldwide.

Solutions to air pollution

According to a UNICEF report, almost 2,000 children under five years of age die every day due to health issues linked to air pollution. This is a pressing global issue, with children in poorer countries suffering the worst impacts. Air pollution is the second-leading risk factor for death in this age group, after malnutrition.

To address this dire situation, here are some solutions to reduce air pollution and protect children's health:

Policy Changes and Government Intervention

Passing laws and implementing policies to regulate air pollution is crucial. Governments should prioritize creating and enforcing regulations that limit emissions and improve air quality. For instance, the Clean Air Act in the United States, passed in 1970, has successfully reduced pollution while allowing for economic growth. Similar legislation, like China's frequently updated five-year national plan, can be implemented in other countries to meet targeted reductions in air pollution.

Phasing Out Fossil Fuels

Transitioning from fossil fuels to clean and renewable energy sources is essential. According to studies, phasing out fossil fuels could prevent approximately 3.6 million premature deaths annually, which are currently caused by burning fossil fuels in power generation, transportation, and industry.

Reducing Vehicle Emissions

Vehicle exhaust is a significant contributor to air pollution. Encouraging the use of public transportation, carpooling, biking, and electric vehicles can help reduce vehicle emissions. Additionally, maintaining vehicles properly and fixing exhaust problems promptly can lower emissions.

Improving Industrial Practices

Industrial activities, including factories and power plants, release toxic pollutants. By adopting new technologies and stricter emissions standards, emissions from these sources can be decreased. For example, the phasing out of lead in motor vehicle gasoline has led to significant health benefits.

Addressing Residential Energy Use

Residential energy use, particularly heating and cooking, significantly contributes to both indoor and outdoor air pollution. Promoting the use of clean and efficient energy sources for residential purposes can help reduce pollution levels.

Community Education and Action

Educating communities about air pollution and providing guidance on reducing it is essential. This includes encouraging the use of electric or hand-powered lawn equipment, limiting backyard fires, and choosing energy-efficient appliances. Additionally, local businesses, city offices, and school districts should be directed towards programs that can help them become more sustainable.

By implementing these solutions and recognizing the urgency of the problem, we can work towards reducing air pollution and protecting the health and future of children worldwide.
