Plastic Pollution: Harming Humans, Damaging Our Health

Plastic pollution has a detrimental impact on the environment, animals and humans. The effects on one system have consequences for another, and so the interconnections of plastic pollution affect human health through multiple pathways. For example, plastic pollution can cause chemical toxicity, alter soil's physical structure, and contaminate water supplies. Plastic additives and toxic chemicals can leach into the soil and water, affecting food systems and human health. Microplastics have been found in human livers, kidneys, and placentas, and the carcinogenic chemicals found in plastic products may cause developmental, reproductive, neurological, and immune disorders.

Plastic pollution is a growing problem that affects human health through multiple pathways. One of the ways it can harm human health is by causing chemical toxicity. When plastic degrades, it can release toxic chemicals into the soil and water supplies. These chemicals can then be ingested by humans, leading to potential health risks.

One of the most concerning aspects of plastic pollution is its impact on vulnerable groups, including children, pregnant women, and marginalised communities. Children are particularly at risk, with increased chances of prematurity, stillbirth, birth defects of the reproductive organs, neurodevelopmental impairment, impaired lung growth, and childhood cancer. The adverse effects of plastic pollution on children in the womb and young children have been documented by the Minderoo-Monaco Commission on Plastics and Health in 2023.

In addition to the direct health impacts, plastic pollution can also contribute to climate change, biodiversity loss, and reduced food supplies. This, in turn, can have further consequences for human health, such as malnutrition and the increased prevalence of infectious diseases.

While more research is needed to fully understand the potential human health impact of microplastics, the existing evidence suggests that plastic pollution can have significant and far-reaching consequences for human health. The global health sector must work together to address this growing problem and find solutions to mitigate the impact of plastic pollution on human health.

Plastic pollution can cause climate change, which can lead to numerous health risks

The health impacts of plastic pollution are observed along the entire plastic value chain. Vulnerable groups, including children, women, workers in the informal waste sector, and marginalised communities, are particularly exposed to the adverse effects of plastic. The health risks associated with plastic pollution include exposure to toxic chemicals, disruption of food supplies, and contamination of water and soil.

Plastics may degrade into microplastics, which can alter the physical structure of soil and reduce its ability to hold water. This can impact plant development and nutrient absorption, affecting food systems and human health. Plastic additives and toxic chemicals can also leach into the soil and contaminate groundwater and other water supplies, harming ecosystems and human health.

Microplastics have been found in human livers, kidneys, and placentas, and the chemicals found in plastic products can leach into tap water, potentially causing developmental, reproductive, neurological, and immune disorders. Climate change, fuelled by plastic pollution, exacerbates these health risks, particularly for vulnerable groups.

While the direct public health harm caused by plastic pollution requires further research, the interconnected impacts on the environment, animals, and humans are clear. The global health sector must address plastic pollution through improved information sharing, collaboration, and capacity building to mitigate the health risks associated with climate change and plastic pollution.

Plastic pollution can contaminate water supplies, which can lead to harmful effects on human health

The health impacts of plastic pollution are observed all along the plastic value chain. Examples include pollution at extraction sites, workers' exposure to chemicals, air pollution from waste incineration, and water and soil contamination. Vulnerable groups, including children, women, workers in the informal waste sector, and marginalised communities, are particularly exposed, raising concerns about human rights and environmental injustice. The adverse effects of plastic are particularly acute for children in the womb and young children, with increased risks of prematurity, stillbirth, birth defects of the reproductive organs, neurodevelopmental impairment, impaired lung growth, and childhood cancer.

The interconnectedness of plastic pollution means that its impact on one system has consequences for another. For example, the environmental effects of plastics can affect animals and humans. Plastic pollution contributes to climate change, biodiversity loss, disruption of carbon dioxide absorption by marine organisms, impacts on soil with possible implications for agriculture, and reduced food supplies and threats to food safety through impacts on marine and land ecosystems. While the evidence about the direct public health harm caused by plastic pollution is incomplete, the downstream consequences of threats to human health, such as disruptions to marine food supplies, must be considered immediately.

Plastic pollution can also alter the physical structure of soil, reducing its ability to hold water. This can impact plant development by inhibiting root growth and nutrient absorption. Plastic additives can also leak into the soil, affecting food systems and human health. When plastic leaches toxic chemicals into the soil, it can contaminate groundwater and other water supplies, which can be harmful to the ecosystem and the animals that consume the water. Microplastics have been found in human livers, kidneys, and placentas, and carcinogenic chemicals found in plastic products can leach into tap water, potentially causing developmental, reproductive, neurological, and immune disorders.

The adverse effects of plastic pollution are particularly acute for children in the womb and young children, with increased risks of prematurity, stillbirth, birth defects of the reproductive organs, neurodevelopmental impairment, impaired lung growth, and childhood cancer. Plastic pollution also contributes to the health risks associated with warming temperatures and extreme weather events due to climate change.

Overall, plastic pollution can have significant impacts on human health, including reduced food supplies and threats to food safety, through its effects on the environment and ecosystems.

Plastic pollution can cause harm to wildlife, which can lead to disruptions in marine food supplies

Plastics can degrade into microplastics, which can alter the physical structure of soil and reduce its ability to hold water. This can impact plant development and nutrient absorption, affecting food systems and human health. Plastic additives and toxic chemicals can also leak into the soil, contaminating groundwater and other water supplies. This can harm the ecosystem and the animals that consume the water, including marine organisms that absorb carbon dioxide.

The health impacts of plastic pollution are observed along the entire plastic value chain. This includes pollution at extraction sites, worker exposure to chemicals, air pollution from waste incineration, and water and soil contamination. Vulnerable groups, including children, women, and marginalised communities, are particularly exposed to these health risks.

While direct evidence of the public health harm caused by plastic pollution is still incomplete, the threats to environmental and animal health are clear and have downstream consequences for human health. Improved information sharing, collaboration, and capacity building are needed to better understand and address the potential health impacts of plastic pollution.
