The Dark Side Of Plastic: Harming Our Planet

Plastic pollution is one of the most pressing environmental issues, threatening both the environment and human health. The production of disposable plastic products has increased rapidly, overwhelming the world's ability to deal with them. Plastic waste is improperly disposed of, ending up in oceans, rivers, and landscapes, causing significant ecological damage and affecting human health. It is estimated that 19-23 million tonnes of plastic waste leak into aquatic ecosystems annually, with plastic items being found everywhere from Mount Everest to the ocean depths. Plastic pollution has severe consequences for wildlife, with millions of animals dying each year from ingestion, entanglement, or starvation due to plastic waste. It also poses risks to human health, with toxic chemical additives causing diseases, disabilities, and premature deaths. The impact of plastic pollution is felt globally, and addressing this crisis requires systemic transformation and improved waste management practices.

Plastic pollution is a global problem, threatening wildlife, habitats, and human populations

The production and use of plastic have led to a throw-away culture, with single-use plastics accounting for 40% of all plastic produced annually. These products have a very short lifespan but can persist in the environment for hundreds of years. The improper disposal of plastic waste is a significant issue, with lightweight single-use plastic products often being discarded at or near the location where they are used, instead of being deposited in containers for proper removal to landfills, recycling centres, or incinerators. This has led to landscapes littered with plastic packaging, clogged drainage systems, and the pollution of lakes, rivers, and seas.

The impact of plastic pollution on wildlife has been devastating, with millions of animals killed by plastic waste every year. Nearly 2,1000 species, including endangered ones, are known to be affected by plastics, with nearly every species of seabird consuming plastic. Animals are entangled in plastic waste, such as abandoned fishing gear or six-pack rings, or starve to death due to stomachs packed with plastic reducing their urge to eat. Microplastics have also been found in more than 100 aquatic species, with potential consequences for human health as these species are part of our food chain.

In addition to the environmental impacts, plastic pollution poses a significant threat to human health. Humans are exposed to toxic chemicals and microplastics through inhalation, ingestion, and direct skin contact at every stage of the plastic lifecycle. While research on the health impacts of plastic is still emerging, scientific results indicate that plastic causes diseases, disabilities, and premature death. The toxic chemical additives and pollutants found in plastics have been linked to cancer, endocrine disruption, reproductive issues, growth impairment, and cognitive impairment. The health effects of plastic production have also resulted in significant monetary costs, with an estimated global cost of more than $250 billion in 2015.

Plastic waste is often mismanaged, ending up in oceans, rivers, and lakes

Improper disposal of plastic waste is a significant contributor to plastic pollution in water bodies. Plastic products, particularly lightweight single-use items and packaging materials, are often discarded at or near the location where they are used, instead of being placed in designated containers for proper removal to landfills, recycling centres, or incinerators. This includes litter dropped on streets, thrown out of car windows, or added to already full trash bins, which can be carried away by wind or rainwater into streams, rivers, and eventually the ocean. Improper disposal also includes flushing plastic items down toilets, such as wet wipes, cotton buds, and sanitary products, which can release microfibres into waterways.

Littering and illegal dumping further exacerbate the problem. Plastic waste that is not properly secured or contained can be blown away or washed into drains and waterways, ultimately reaching oceans and lakes. This is particularly prevalent in areas with overflowing containment structures or inadequate waste management systems, which struggle to keep up with increasing plastic consumption.

The plastic that ends up in oceans, rivers, and lakes poses a significant threat to the environment and human health. It affects marine life, with over 1,500 species known to ingest plastics, and it can alter habitats and natural processes, reducing ecosystems' ability to adapt to climate change. Additionally, plastic pollution impacts human health, with plastic materials being carcinogenic and affecting the endocrine system. The economic costs of plastic pollution in the ocean are also substantial, estimated to be between $6-19 billion USD annually, due to impacts on tourism, fisheries, and clean-up efforts.

To address this issue, it is crucial to improve waste management systems, promote recycling, and reduce the use and production of plastic, especially single-use plastics. Individual behaviour changes, such as reducing plastic consumption and properly disposing of waste, are important, but systemic transformations are also necessary to achieve a circular economy and effectively tackle plastic pollution in oceans, rivers, and lakes.

Plastic production and disposal contribute to greenhouse gas emissions, exacerbating climate change

Plastic pollution is a significant threat to the environment, and its production and disposal contribute to greenhouse gas emissions, exacerbating climate change. The life cycle of plastics, from production to disposal, emits heat-trapping gases at every stage. The production stage, which involves converting fossil fuels into plastics, accounts for the majority of these emissions, primarily in the form of carbon dioxide. The Organisation for Economic Co-operation and Development (OECD) estimated that in 2019, the life cycle of plastic products was responsible for 3.4% of global greenhouse gas emissions, with 90% coming from the production and conversion of fossil fuels.

The refining process for plastics is particularly greenhouse-gas intensive. For example, the production of ethylene, a building block for polyethylene plastics, emitted 184.3 to 213 million metric tons of carbon dioxide equivalent in 2015. This is projected to increase by 34% between 2015 and 2030. Additionally, about 40% of plastics are used for packaging, which often ends up in landfills, is incinerated, or recycled. Incineration has the most significant climate impact among these options, and emissions from plastics incineration are expected to increase.

The plastic industry's plans for expanded production threaten to worsen the climate impact of plastics. Projections indicate that by 2050, plastic production and incineration could emit 2.8 gigatons of CO2 per year. This cumulative emission will accumulate in the atmosphere over time, making it increasingly challenging to limit global temperature rise to 1.5°C. The continued growth in plastic production and incineration is predicted to result in greenhouse gas emissions of over 56 gigatons of CO2 equivalent by 2050, exceeding the remaining carbon budget.

To mitigate the climate impact of plastics, urgent action is required. Suggested measures include ending the production and use of single-use disposable plastics, halting the development of new oil, gas, and petrochemical infrastructure, and fostering a transition to zero-waste communities. Without intervention, the global plastics industry is projected to account for 20% of total oil consumption and up to 15% of global carbon emissions by 2050. Addressing plastic pollution and its contribution to climate change requires a systemic transformation towards a circular economy and responsible production and consumption practices.

Plastic waste affects human health, causing diseases, disabilities, and premature death

Plastic waste is a global crisis that negatively affects the environment and human health at every stage of its lifecycle. Humans are exposed to toxic chemicals and microplastics through inhalation, ingestion, and direct skin contact.

The average person is estimated to ingest approximately 5 grams of plastic every week, although the amount is not known with scientific certainty. These plastic particles can enter the digestive system and contribute to health issues. They can also be inhaled and impact the lungs and bloodstream. Even vegetarians and those who only eat fruit and vegetables are at risk of consuming plastics, as microplastics are found in the air, water, and crops.

The health effects of plastic waste include causing diseases, disabilities, and premature death. Scientific results indicate that toxic chemical additives and pollutants found in plastics threaten human health on a global scale. These chemicals can cause cancer, change hormone activity (known as endocrine disruption), and lead to reproductive, growth, and cognitive impairment. They have also been linked to infertility, obesity, diabetes, thyroid problems, and an increased risk of cardiovascular disease and stroke.

Vulnerable groups, including children, pregnant people, women, workers in the informal waste sector, and marginalized communities, are particularly exposed to the health risks of plastic waste. For example, studies have found increased risks of prematurity, stillbirth, birth defects of the reproductive organs, neurodevelopmental impairment, impaired lung growth, and childhood cancer in these populations.

The long-term effects of plastic waste on human health are still being studied, and the full impact may not be known for some time. However, it is clear that plastic waste is a significant threat to human health and well-being.

Plastic pollution is particularly harmful to children, with increased risks during fetal development and early life

Plastic pollution is a pressing global issue that poses significant risks to the environment and human health, especially during fetal development and early childhood. The impact of plastic pollution is felt across a wide range of areas, from biodiversity and climate change to human health and human rights.

Plastic pollution encompasses not just plastic items themselves but the entire lifecycle of plastic, from the extraction and refining of fossil fuels to disposal in landfills, incineration, or exportation overseas as waste. This waste is often dumped, burned, or picked through by millions of people worldwide, particularly women and children, exposing them to toxic chemicals. These toxic chemicals, such as endocrine disruptors, can accumulate in the body's fat cells, leading to health issues like cancer, reproductive problems, growth impairment, and cognitive impairment.

Children, with their developing bodies, sensitive hormones, and immune systems, are among the most vulnerable to the toxic impacts of plastic pollution. This vulnerability is heightened during fetal development and early life, as these are critical periods for establishing the foundations of lifelong health and well-being. Exposure to plastic pollutants during these stages can have long-lasting effects on fetal growth, child development, and health in later life.

Evidence suggests that plastic pollutants can be transmitted to unborn children through placental transfer, ingestion, and breastmilk, as well as dermal absorption and inhalation. Studies have found microplastics in human placentas on both the maternal and fetal sides, indicating that exposure to plastic pollution can occur even before birth. Additionally, playgrounds and outdoor spaces, where children often spend time, have been found to contain high concentrations of microplastics due to plastic equipment and ground coverings.

The widespread presence of plastic and the associated health risks underscore the importance of education and community-level change to reduce plastic pollution exposure. Initiatives like the Healthy Pregnancy Guide and Healthy Baby Guide offer guidance to expecting parents and guardians on minimizing toxin exposure during pregnancy, infancy, and childhood.
