Pollution's Inequality: Poor Suffer More

Air pollution is a pressing global issue, causing approximately 7 million deaths annually. It is estimated that 94% of the world's population breathes unsafe air, with 2.8 billion people exposed to hazardous pollution levels, increasing their mortality rate by more than 24%. This issue disproportionately affects the poor, with socioeconomic inequalities contributing to higher exposure and vulnerability among low-income communities. Factors such as residential segregation, proximity to pollution sources, limited access to healthcare, and political dynamics contribute to the burden of pollution faced by impoverished groups. Addressing this inequity requires targeted measures, such as improving healthcare access, steering pollution sources away from low-income areas, and promoting equitable adoption of clean technologies.

Poorer people are exposed to higher levels of pollution

In the United States, low-income communities are disproportionately exposed to air pollution. Contributing factors include a lack of emissions regulations, the placement of pollution sources near low-income neighborhoods, and the excessive political power of large emitters. These factors lead to negative consequences for low-income individuals, including physical and mental health issues and impaired cognitive function.

The impact of pollution on poorer communities is also evident in developing countries, where most recorded air pollution-linked deaths occur. In these countries, weak laws, less stringent vehicle emission standards, and prevalent coal power stations contribute to poor air quality. Additionally, in big cities, the poorest often live in cramped settlements near rubbish dumps, exposing them to toxic fumes that affect their health and well-being.

The correlation between poverty and pollution is further exacerbated by limited access to healthcare, good jobs, and clean technologies. As a result, low-income populations experience more severe health risks and vulnerabilities due to the compounding effects of pollution and poverty.

Addressing this issue requires targeted measures such as improving access to affordable healthcare, mandating transparent accounting for environmental and health externalities, and removing incentives for the over-consumption of polluting fuels.

Ethnic minorities are disproportionately affected by pollution

Poor people and certain racial and ethnic groups are exposed to higher levels of pollution and may experience more severe consequences. This is due to a variety of factors, including racism, class bias, housing market dynamics, and land costs. Pollution sources are often located near disadvantaged communities, increasing exposure to harmful pollutants.

Another study found that Hispanics and Asians, but especially blacks, had a higher risk of premature death from particle pollution than whites. This study suggested that factors other than income, such as chronic stress due to discrimination, may play a role in the increased risk for minorities. Additionally, due to decades of residential segregation, African Americans tend to live in areas with greater exposure to air pollution.

The impacts of climate change are largely felt by those who suffer from socioeconomic inequalities, and people of colour are particularly vulnerable to heatwaves, extreme weather events, environmental degradation, and subsequent labour market dislocations. Environmental racism refers to the unequal access to a clean environment and basic environmental resources based on race. Communities of colour are disproportionately harmed by environmental hazards and are more likely to live in heavily polluted areas.

To address these disparities, targeted measures are needed to reduce the pollution intensity of economic growth and directly address the disproportionate exposure of poor and minority communities to pollution. This includes improving access to affordable and adequate healthcare in large urban centres and steering pollution sources away from low-income and minority communities.

Poor air quality impacts physical and mental health

Poor air quality is estimated to cause around 7 million deaths each year, contributing to 1 in 6 deaths globally. It is a pressing public health hazard, with 94% of the world's population breathing air that is deemed unsafe by the WHO. Those from low-income communities are most at risk from the adverse health effects of air pollution.

The main pathway of exposure to air pollution is through the respiratory tract. Pollutants cause inflammation, oxidative stress, immunosuppression, and mutagenicity in cells throughout the body, impacting the lungs, heart, and brain, among other organs. Fine particulate matter, such as PM2.5, is a critical pollutant, as these tiny particles can penetrate deep into the lungs, enter the bloodstream, and travel to organs, causing systemic damage to tissues and cells. This can lead to respiratory and heart diseases, adverse birth outcomes, and potentially, cancer.

Low-income individuals suffer from both physical and mental health consequences due to overexposure to air pollution. Contributing factors to this disproportionate exposure include the placement of pollution sources near low-income neighborhoods, a lack of emissions regulations, and the excessive political power of large emitters. Additionally, low-income communities may have poorer housing conditions, such as inadequate ventilation systems, and face higher traffic exposure, further increasing their risk of harm.

The health risks associated with air pollution are compounded by limited access to affordable healthcare in these communities. Furthermore, certain racial and ethnic minority groups, such as African Americans and Hispanics, are more likely to live in areas with higher particle and ozone pollution, facing higher health risks.

The impacts of air pollution on physical and mental health are evident, and the disproportionate exposure of low-income communities exacerbates the issue. It is crucial to address this disparity through measures such as improving healthcare access and steering pollution sources away from these vulnerable areas.

Pollution sources are disproportionately placed near low-income areas

Air pollution is a pressing public health hazard, causing approximately 9 million deaths per year globally. It is linked to several health issues, including respiratory diseases, heart disease, and adverse birth outcomes. While air pollution affects everyone, those from low-income communities are at a higher risk of exposure and experience more severe health consequences.

Several factors contribute to the disproportionate exposure of low-income communities to air pollution. Firstly, pollution sources, such as industrial plants, transport corridors, and factories, are often disproportionately placed near low-income neighborhoods. This proximity increases the exposure of individuals living in these areas to harmful pollutants. Additionally, low-income individuals may have limited options to escape their exposure to pollution due to their geographical proximity to busy roads, schools, or workplaces. For example, the inquest hearing into the death of Ella Kissi-Debrah, a 9-year-old London schoolgirl, attributed her asthma-related death to her home's close proximity to a busy road.

Secondly, socioeconomic inequalities play a significant role. Ethnic minorities and low-income populations often face higher exposure to pollution due to residential segregation, lack of emissions regulations, and the excessive political power of large emitters. Furthermore, low-income individuals may have constrained access to healthcare, making them more vulnerable to the health impacts of pollution. They may also be more likely to rely on public transportation, increasing their exposure to traffic pollution.

Lastly, housing market dynamics and land costs contribute to the disparity. Low-income individuals may be priced out of areas with better air quality, such as the leafy suburbs with fewer highways. Instead, they may be concentrated in cramped informal settlements near rubbish dumps, power stations, or industrial zones, further exposing them to toxic fumes and indoor air pollution from burning wood, charcoal, or kerosene for cooking, heating, or lighting.

Addressing this issue requires targeted measures to reduce the pollution intensity of economic growth. This includes supporting the uptake of clean technologies and fuels, improving healthcare provisions in large urban centers, and mandating transparent accounting for environmental and health externalities in planning decisions to steer pollution sources away from low-income communities.

Poor people have less access to affordable healthcare

Air pollution is a pressing issue that affects billions of people worldwide. It is a major problem in the United States, and low-income communities are disproportionately exposed to air pollution compared to wealthier individuals. This is due to various factors, including the placement of pollution sources near low-income neighborhoods, a lack of emissions regulations, and the political power of large emitters. The negative consequences of air pollution exposure include physical and mental health issues, impaired cognitive function, respiratory diseases, heart disease, and adverse birth outcomes.

Poor people are more vulnerable to the adverse effects of air pollution due to their limited access to affordable healthcare. In the United States, the high cost of health insurance is a significant barrier for many, with 63% of uninsured adults aged 18-64 citing cost as the main reason for lacking coverage. Even with the expansion of Medicaid and Marketplace coverage, which provided a safety net for many during the pandemic, the cost of healthcare remains unaffordable for some. This lack of financial protection means that families in the US and other affluent regions, such as Eastern Asia, Latin America, and Europe, spend a significant portion of their household budgets on out-of-pocket health expenses.

The lack of access to affordable healthcare has severe consequences for the health and well-being of poor people. Studies show that uninsured individuals are less likely to receive preventive care and services for major health conditions and chronic diseases. They are more likely to delay or forgo care due to costs, leading to higher hospitalization rates and increased mortality. This disparity in access to healthcare exacerbates the impact of air pollution on low-income communities, as they bear the brunt of both the exposure to pollution and the lack of adequate healthcare.

The issue of inadequate access to affordable healthcare among the poor is not limited to the United States. Globally, half of the world's population lacks access to essential health services, according to the World Bank and WHO. This lack of access pushes approximately 100 million people into extreme poverty due to the high cost of healthcare. The financial strains of accessing health services can negatively impact health behaviors and outcomes, creating a cycle of poverty and poor health that is difficult to break.

To address these disparities, targeted measures are necessary. Improving the provision of affordable and adequate healthcare in urban centers, mandating transparent accounting for environmental and health externalities, and removing incentives for the over-consumption of polluting fuels can help reduce the burden of air pollution on low-income communities. Additionally, universal health coverage can play a crucial role in ensuring that everyone has access to the health services they need, breaking the cycle of poverty and improving health outcomes for disadvantaged populations.
