Plastic Pollution: Harming Our Atmosphere And Environment

Plastic pollution is a pressing issue that affects all ecosystems and has serious consequences for human health and the environment. It is a significant contributor to biodiversity loss, ecosystem degradation, and climate change. With an annual production of over 460 million metric tons, plastic has become an omnipresent pollutant, from Mount Everest to the Mariana Trench. The problem is not just limited to the oceans but extends to the atmosphere as well. Recent studies have found that microplastics, tiny pieces of plastic, are being lofted into the skies and can travel thousands of miles, potentially impacting cloud formation and influencing temperature, rainfall, and climate change. The burning of plastic waste, a common practice, releases toxins and greenhouse gases, further contributing to air pollution and climate change.

Plastic pollution affects climate change

Plastic pollution is a pressing issue that affects every corner of the planet, from Mount Everest to the Mariana Trench. It is a significant contributor to climate change, and its impact is expected to grow in the coming decades. Here are some ways in which plastic pollution affects climate change:

Greenhouse Gas Emissions

Plastic is derived from fossil fuels, such as natural gas and crude oil, and its production emits vast amounts of greenhouse gases. The extraction and transportation of these fossil fuels, as well as the refining and manufacturing processes, result in significant carbon dioxide emissions. For example, the refinement of plastics emits an additional 184 to 213 million metric tons of greenhouse gases annually. The incineration of plastic waste, a common method of disposal, further contributes to these emissions, with the United States alone emitting 5.9 million metric tons of carbon dioxide equivalent in 2015.

Microplastics and the Atmosphere

Microplastics, tiny pieces of plastic, are being lofted into the atmosphere and can travel thousands of miles. They have been found in the air, water, soils, crops, and even in human lungs. These microplastics can affect cloud formation, potentially influencing temperature and rainfall patterns and, consequently, climate change. While the proportion of plastics to total airborne aerosols is currently small, the production and accumulation of plastic in the environment continue to increase.

Endangerment of Marine Organisms

Plastic pollution in the oceans poses a significant threat to marine life. Marine animals, such as turtles, often ingest or become entangled in plastic waste. Additionally, toxic chemicals can bind to microplastics, creating poison pills that aquatic organisms consume. Plankton, which plays a crucial role in sequestering carbon dioxide from the atmosphere, has been found to have its ability to remove carbon dioxide diminished after ingesting microplastics.

Deforestation and Land Disturbance

The extraction of fossil fuels for plastic production also contributes to deforestation and land disturbance. Clearing forested land for oil extraction and pipeline construction releases carbon dioxide into the atmosphere and limits the planet's ability to remove carbon dioxide through photosynthesis. This land disturbance contributes to greenhouse gas emissions associated with the extraction process.

Impact on Vulnerable Communities

Plastic pollution and its consequences disproportionately affect vulnerable communities, particularly during the disposal stage. Incineration facilities and landfills are often located near communities of color and low-income populations. These communities bear the brunt of the pollution and health risks associated with plastic waste incineration and the release of toxic substances.

Plastic extraction and transportation contribute to air pollution

Plastic is derived from fossil fuels, including natural gas and crude oil. The extraction of these raw materials and their transportation to plastic factories emit 1.5 to 12.5 million metric tons of greenhouse gases. Oil and gas drilling releases enormous amounts of contaminants into the air, including benzene, toluene, ethylbenzene, xylene, carbon monoxide, hydrogen sulfide, ozone, sulfur dioxide, particulate matter, and volatile organic compounds. Removing forested land for oil extraction and pipeline construction has also released more than 1.6 billion metric tons of carbon dioxide into the atmosphere. This land clearing also limits the amount of carbon dioxide removed from the atmosphere. The refinement of plastics emits an additional 184 to 213 million metric tons of greenhouse gases each year.

The transportation of plastics also contributes to air pollution. The enormous floating mass of plastic in the Pacific Ocean, twice the size of Texas, is growing due to plastic waste from coastal nations and rivers that act as conveyor belts, picking up trash as they move downstream. Once caught up in ocean currents, plastic waste can be transported around the world. For example, scientists found plastic items from Russia, the United States, Europe, South America, Japan, and China on Henderson Island, an uninhabited atoll in the South Pacific.

The extraction and transportation of plastics contribute to air pollution by releasing greenhouse gases and other contaminants into the atmosphere. The decomposition of plastics also contributes to air pollution, as landfills, where single-use plastics are sent, account for more than 15% of methane emissions.

Plastic incineration releases toxins into the atmosphere

Plastic incineration is a major source of air pollution. Burning plastic waste releases toxic gases and pollutants into the atmosphere, posing a significant threat to human health and the environment.

The process of incineration involves burning waste, often mixed municipal solid waste, to generate a small amount of electricity in what are known as waste-to-energy (WTE) facilities. However, this process produces carbon dioxide emissions, air pollutants, fly-ash, and other solid waste residues. For every tonne of plastic burned, up to three tonnes of CO2 are released into the atmosphere. Incineration also generates toxic emissions, including dioxins, particulate matter, carbon monoxide, nitrogen oxides, acidic gases, metals, polychlorinated biphenyls (PCBs), and brominated polyaromatic hydrocarbons (PAHs). These emissions pose risks to the well-being of workers, nearby residents, and the environment.

The toxic substances released from burning plastic have severe health implications. They have been linked to the development of asthma, endocrine disruption, reproductive issues, and cancer. These toxins can also settle on crops and in waterways, eventually entering our food systems and bodies. The impact of plastic incineration on human health is particularly evident in communities near incinerator facilities, with increased rates of adverse health outcomes such as preterm births, wheezing, headaches, stomach aches, and fatigue in schoolchildren, and increased risk of miscarriages and lymphoma.

Furthermore, plastic incineration contributes to the microplastics found in the atmosphere. Microplastics can be lofted into the skies from various sources, including seafoam bubbles or spinning tires on highways, and can travel thousands of miles. These tiny plastic particles have the potential to affect cloud formation and influence temperature, rainfall, and even climate change.

The release of toxins through plastic incineration highlights the urgent need for sustainable alternatives and effective waste management strategies to reduce the impact on human health and the environment.

Microplastics can be inhaled and cause health issues

Plastic pollution is a pressing issue that affects every part of the planet, from Mount Everest to the Mariana Trench. A less obvious aspect of this crisis is plastic pollution in the atmosphere. Recent studies have found that microplastics are constantly lofted into the air and can travel thousands of miles, affecting cloud formation and potentially influencing temperature, rainfall, and climate change.

Microplastics, defined as plastic fragments smaller than 5mm in size, are a growing cause for concern due to their potential adverse effects on the environment and human health. These tiny plastic particles are present in both outdoor and indoor air and can be inhaled by humans, posing risks to respiratory health.

Research has shown that microplastics are abundantly present in the air we breathe, both indoors and outdoors. They can be found in household dust, textile fibres, and even in our food and drinking water. The smallest particles can pass into the bloodstream and cause cardiovascular and cerebrovascular diseases. Microplastics have also been detected in human lung tissue, indicating their persistence in the body and potential to cause inflammation.

The health risks associated with inhaling microplastics are still being studied, but preliminary results suggest that they can induce pro-inflammatory or pro-carcinogenic effects. The impact may depend on factors such as particle concentration, size, type, and surface charge. Longer fibres appear to be more damaging, and the presence of microplastics in the lungs may be linked to an increased risk of lung cancer.

Inhalation is a major route of exposure to microplastics, and their presence in the atmosphere has significant implications for human health. As plastic production continues to increase, addressing this issue becomes increasingly crucial to mitigate potential respiratory and other health risks.

Plastic pollution impacts human health and economies

Plastic pollution is a pressing issue that poses risks to human health and economies. The impact of plastic pollution on human health is extensive, affecting people at every stage of plastic's lifecycle, from extraction to disposal. Here are some key ways in which plastic pollution impacts human health and economies:

Impact on Human Health

• Endocrine Disruption: Plastics contain chemicals that are known endocrine disruptors. These chemicals can interfere with hormone production and balance, leading to reproductive problems, hormonal imbalances, and even cancer.
• Ingestion and Inhalation: Microplastics, tiny plastic particles, are present in the air, water, and food we consume. According to the WWF, an average person may ingest approximately 5 grams of plastic every week. These microplastics can accumulate in the body and cause various health issues, including intestinal blockages and punctured organs.
• Cardiovascular and Respiratory Issues: The smallest microplastic particles can enter the bloodstream and cause cardiovascular and respiratory diseases. They have been found in human lung, muscular, and lung tissue.
• Developmental and Reproductive Issues: Plastic pollution has been linked to adverse effects on fetal and child development, including increased risks of prematurity, birth defects, impaired lung growth, and childhood cancer.
• Toxic Chemical Exposure: The production and incineration of plastics release toxic chemicals into the air, water, and soil. These chemicals include heavy metals, persistent organic pollutants (POPs), and other toxic substances, which can have both short-term and long-term health impacts, such as asthma, endocrine disruption, and cancer.
• Impact on Vulnerable Groups: Vulnerable groups, including children, women, workers in the waste sector, and marginalized communities, are particularly exposed to the health risks associated with plastic pollution, raising concerns about human rights and environmental injustice.

Impact on Economies

• Environmental Cleanup Costs: The economic impact of plastic pollution is significant, with the costs of addressing and cleaning up plastic waste falling on governments and communities. For example, the costs of diseases and disabilities caused by plastic-associated chemicals in the USA alone were estimated at over $920 billion in 2015.
• Damage to Natural Resources: Plastic pollution contaminates soil, water, and natural resources, threatening food security and economic activities dependent on a healthy environment, such as agriculture, fisheries, and tourism.
• Negative Effects on Wildlife: Plastic pollution harms wildlife, with over a million creatures in the sea estimated to die from plastic waste each year. This has a direct impact on economies, particularly in industries such as fishing and eco-tourism.
• Ineffective Waste Management Systems: Ineffective waste management systems struggle to keep up with the growing plastic waste stream, leading to increased disposal costs and challenges in recycling and waste management.
• Impact on Developing Countries: Developed countries often send their plastic waste to developing countries for processing, overwhelming these communities with plastic trash and creating economic and social burdens.
