Environmental Racism: Air Pollution's Injustice

Environmental injustice refers to the unequal distribution of environmental burdens and risks among socially and economically marginalized communities. It is a pervasive issue, with air pollution disproportionately affecting communities of color, low-income communities, and ethnic minorities. These communities are more likely to be located near industrial facilities, power plants, and major roadways, bearing the brunt of toxic emissions and poor air quality. The adverse health effects of air pollution on underserved populations can lead to higher rates of respiratory and cardiovascular issues, pregnancy complications, and even premature death. The interconnection between environmental injustice and systemic racism has been highlighted by the COVID-19 pandemic and the Black Lives Matter movement, with Black Americans experiencing higher mortality rates due to pollution-induced health conditions. The fight for environmental justice aims to address these disparities by advocating for stricter environmental regulations, equal access to decision-making processes, and the empowerment of affected communities to promote sustainable change.

Marginalised communities are disproportionately affected by air pollution

Several factors contribute to the disproportionate impact of air pollution on marginalised communities. Firstly, low-income communities tend to be more exposed to unsafe air pollution levels due to their proximity to pollution sources, such as industrial zones or power plants, and their dependence on jobs that require outdoor physical labour. For example, a study of New Jersey residents found that communities with larger African American populations, lower home values, and lower median incomes were at a higher risk of premature death from long-term exposure to particle pollution.

Secondly, marginalised communities may have limited access to adequate and affordable healthcare, which increases their vulnerability to pollution-related health issues and mortality rates. This lack of resources and healthcare can perpetuate cycles of poverty and oppression, making it difficult for individuals to escape poverty. Additionally, low-income communities may rely on polluting, low-cost fuels such as charcoal, kerosene, or firewood for cooking and lighting, further exacerbating their exposure to indoor air pollution.

Furthermore, historical discrimination in housing, education, employment, and healthcare has contributed to the increased vulnerability of underserved communities. This includes underinvestment in communities of colour and other marginalised groups, leading to a lack of green spaces and guaranteed access to basic natural resources like clean water. The negative impacts of air pollution on marginalised communities can also have transgenerational effects, affecting the health and well-being of future generations.

Addressing this environmental injustice requires recognising the link between fighting climate change and promoting environmental justice. This includes ensuring equal participation of communities in decision-making processes affecting their environment and implementing stricter environmental regulations that protect vulnerable groups. Additionally, expanding access to affordable and quality healthcare in low-income areas can help reduce mortality rates and mitigate the disproportionate impact of air pollution on marginalised communities.

Systemic racism and segregation

Residential segregation creates worse physical environments for racial and ethnic minorities, with higher concentrations of air pollution and limited opportunities to move away from polluted areas. Segregation also contributes to spatial segmentation within metropolitan areas, increasing commute times and air pollution from mobile sources. Furthermore, the spatial concentration of poverty and lack of socioeconomic opportunities associated with residential segregation perpetuate power differentials that influence the siting of hazardous pollution sources.

Low-income communities and ethnic minorities often bear the brunt of environmental pollution, facing higher exposure to air pollutants and a lack of access to green spaces and basic natural resources like clean water. This inequality in exposure to air pollution is a result of systemic racism, where people of color and pollution have been pushed together due to housing policies and other factors. The economic interests of industries and large corporations often take precedence over environmental concerns, exacerbating the problem.

The adverse health effects of air pollution disproportionately impact marginalized communities, affecting both physical and mental health. Children are particularly vulnerable, as exposure to air pollution during their developmental years can have detrimental effects on their health that may persist into adulthood and even have transgenerational impacts. The lack of resources and adequate healthcare in underserved communities contributes to cycles of poverty and oppression, hindering their ability to escape these detrimental living conditions.

Addressing environmental injustice requires the active participation of affected communities in decision-making processes related to their environment. Environmental justice aims to defend social and environmental equity through legal obligations, ensuring equal opportunities for all to enjoy a healthy environment. Stricter environmental policies and regulations are necessary to protect marginalized communities from the negative consequences of air pollution and to promote environmental equity.

Lack of access to basic natural resources

Environmental injustice refers to the unequal distribution of environmental risks and the disproportionate impact of environmental hazards on certain communities. This is often due to systemic racism, segregation, and discriminatory practices and policies over time.

One key aspect of environmental injustice is the lack of access to basic natural resources, such as clean air, water, and green spaces. This is particularly prevalent in communities of color and low-income communities. For example, in the United States, African Americans and low-income communities are disproportionately affected by air pollution, with many living near industrial facilities and natural gas facilities, exposing them to toxic chemicals and increasing their risk of health issues.

The lack of access to basic natural resources is often a result of historical disinvestment in these communities, as well as the siting of toxic facilities in these areas due to lower property values. Redlining, a practice of designating certain areas as hazardous, has denied residents in these communities access to basic public and private services, such as healthcare and parks. Additionally, the weakening of environmental rules and regulations by governments has further exacerbated the issue, with marginalized communities suffering from inadequate enforcement of safe drinking water acts and clean power plans.

The impacts of a lack of access to basic natural resources can be devastating, leading to higher rates of child mortality, respiratory issues, and other health problems. It also contributes to cycles of poverty and oppression, as low socioeconomic status and poor health make it difficult for individuals to improve their economic situation.

To address this issue, it is crucial to involve affected communities in decision-making processes and provide resources in languages other than English. Additionally, organizations such as the NAACP's Environmental and Climate Justice Program work to address harmful practices and rectify past injustices. By recognizing the intersection of environmental issues with racial and economic inequalities, we can work towards fair and sustainable solutions.

Transgenerational health effects

Air pollution is a serious threat to human health and is one of the leading causes of death in Southeast Asian countries, including India. It has been linked to various diseases, including cardiovascular disease, respiratory disease, and cancer. Recent studies have also found a link between air pollution and poor mental health, with an increased risk of internalizing psychopathology, including anxiety and depressive disorders.

The impact of air pollution may be transgenerational, affecting not just the exposed individual but also their children and grandchildren. This is because exposure to air pollutants can cause epigenetic modifications, which provide the basis for phenotypic changes that underlie the development of complex non-communicable diseases. These modifications may persist through downstream generations, resulting in transgenerational epigenomic inheritance. For instance, exposure to air pollution during pregnancy can impact the health of the fetus, with changes to their genes that can be passed on to future generations.

Several environmental exposures have suggestive evidence of transgenerational epigenetic inheritance, including pesticides, lead, and diesel exhaust. Additionally, maternal exposure to fine particulate matter (PM2.5) has been linked to neurodevelopmental disorders in offspring, with alterations in brain regions implicated in the risk of psychopathology.

While the full extent of the transgenerational health effects of air pollution is not yet fully understood, the recent literature strengthens the contention that air pollution contributes to the transmission of epimutations from gametes to zygotes. Larger prospective studies are needed to assess the air pollution-induced transgenerational epigenetic inheritance and its impact on human health.

Climate change and environmental injustice are linked

Climate change and environmental injustice are undeniably linked. Environmental injustice occurs when communities are disproportionately affected by environmental degradation, such as air pollution, due to factors like socioeconomic status, race, and historical discrimination. Climate change exacerbates these injustices, disproportionately impacting marginalized communities, including communities of color, immigrants, low-income populations, and non-native English speakers.

Underserved and marginalized communities often bear the brunt of environmental injustices. They suffer from higher concentrations of air pollution, inadequate healthcare, and a lack of access to basic natural resources like clean water and green spaces. This is a result of historical discrimination in housing, education, employment, and healthcare, as well as underinvestment in these communities. Climate change intensifies these injustices, as marginalized communities are more vulnerable to its effects due to limited resources and adaptive capacity.

The negative impacts of climate change, such as rising temperatures, increased frequency and intensity of natural disasters, and sea-level rise, disproportionately affect marginalized communities. For example, communities of color in the United States are more prone to flooding due to historical racism and redlining policies that forced them into substandard housing and minority neighborhoods. As a result, they are often unable or unwilling to move to safer locations, exacerbating the impacts of climate change-induced flooding.

Addressing environmental injustice and combating climate change go hand in hand. It is crucial to acknowledge the historical neglect and racism that have contributed to the vulnerability of marginalized communities. By recognizing the link between climate change and environmental injustice, we can work towards creating sustainable, cooperative, and regenerative communities that uphold the rights of all people in harmony with the Earth. This includes ensuring equal access to decision-making processes, advocating for transportation equity, and facilitating participatory democracy to address the injustices faced by marginalized communities.
