Plastic pollution is a pressing environmental issue that affects people, wildlife, and ecosystems worldwide. It is caused by the overwhelming rise in disposable plastic products, with single-use plastics being a major contributor. Plastic waste, when not properly managed through recycling or adequate disposal methods, becomes an environmental pollutant. This mismanagement is more prevalent in low- to middle-income countries, particularly in Asia, due to insufficient waste management infrastructure. Plastic pollution has infiltrated every ecosystem, from oceans to freshwater systems and the Antarctic tundra to tropical coral reefs. It poses risks to biodiversity, climate change, human health, and human rights. The pervasive nature of plastic pollution has prompted efforts for a global treaty to address this crisis.

Humans: microplastics found in human organs, blood, and placentas
Plastic pollution is a global problem, with around 19-23 million tonnes of plastic waste entering aquatic ecosystems every year. This waste can alter habitats and natural processes, impacting millions of people's livelihoods, food production capabilities, and social well-being. People are exposed to plastic waste through various routes, including ingestion of contaminated food and water, inhalation, and skin contact. The health risks associated with plastic waste exposure are a growing concern, especially with the discovery of microplastics in human organs, blood, and placentas.
In a groundbreaking discovery, microplastics were detected in the blood of humans for the first time. The study, conducted by Prof Dick Vethaak, an ecotoxicologist, found plastic particles in the blood samples of 17 out of 22 healthy adult donors. This finding indicates that microplastics can circulate in the human body and may have potential health impacts. Previous research has shown that microplastics were found in higher concentrations in the faeces of babies compared to adults, suggesting that infants may be more vulnerable to the effects of plastic exposure.
The presence of microplastics in the blood raises concerns about their potential to affect human organs. Studies have already indicated the presence of microplastics in human biological samples such as breast milk, stool, sputum, and urine. Additionally, microplastics have been detected in human tissues and organs, including the spleen, where they may accumulate environmental contaminants. The exact entry routes of microplastics into these organs remain unclear, and further research is needed to assess their potential health effects.
Furthermore, microplastics have been detected in the placentas of pregnant women, raising concerns about potential impacts on fetal development. A study published in 2020 analyzed six human placentas and found microplastic fragments in four of them, with particles present on both the maternal and fetal sides. While the long-term effects of these findings are unknown, microplastics have the potential to act as endocrine disruptors, which could result in long-term health consequences.
The discovery of microplastics in human blood, organs, and placentas underscores the urgent need for further research on the health impacts of plastic pollution. As plastic production continues to increase, it is crucial to allocate resources towards understanding the potential risks posed by microplastics to human health, particularly in vulnerable populations such as infants and pregnant women. While the exact mechanisms and health effects remain to be fully elucidated, the presence of microplastics in these vital parts of the human body highlights the far-reaching impact of plastic pollution and the need for global efforts to address this pressing environmental and health issue.

Wildlife: ingestion, entanglement, and starvation caused by plastic waste
Plastic waste is a global crisis, with an incredibly harmful impact on wildlife. It is estimated that up to 90% of seabirds and over half of sea turtles have ingested plastic. Marine mammals, from small finches to blue whales, are dying from eating and getting caught in plastic.
Ingestion
Plastic ingestion can cause intestinal injury and death. It can also transfer plastic up the food chain to bigger fish, marine mammals, and humans. Research has found plastic in the guts of fish sold at markets in California, mostly in the form of plastic microfibers. Sea turtles often mistake plastic garbage floating in the water for food. This can lead to choking, internal injury, or death. Even when plastic ingestion does not immediately kill sea turtles, it can cause them to feel full and starve. Tragically, research indicates that half of sea turtles worldwide have ingested plastic.
Entanglement
Entanglement in plastic debris has also led to injury and mortality in many marine species. Abandoned fishing gear, or "ghost gear," is estimated to make up 10% of plastic waste in oceans by volume. This type of plastic waste is the most harmful to marine life, as it continues to capture wildlife, pollute habitats, and enter the food web as it degrades. "Ghost gear" impacts 45% of all marine mammals on the Red List of Threatened Species. For example, large amounts of plastic debris have been found in the habitat of critically endangered Hawaiian monk seals, including in areas that serve as pup nurseries. Similarly, entanglement in plastic has injured and killed the endangered Steller sea lion, with packing bands being the most common entangling material.
Starvation
Plastic ingestion can also lead to starvation in seabirds. Plastic reduces the storage volume of the stomach, causing a feeling of fullness and subsequent starvation. It is estimated that 60% of all seabird species have eaten plastic, with that number predicted to increase to 99% by 2050.

Biodiversity: plastic pollution affects all ecosystems, driving biodiversity loss
Plastic pollution is a pressing environmental issue, threatening ecosystems and driving biodiversity loss. It is a global crisis, with plastic waste found in all ecosystems, from the oceans to freshwater and terrestrial environments. With over 460 million metric tons of plastic produced annually, plastic pollution is a significant threat to biodiversity and ecosystems.
Plastic pollution affects all ecosystems, driving biodiversity loss. Marine ecosystems are particularly affected by plastic pollution, with plastic making up 80% of all marine debris. From surface waters to deep-sea sediments, plastic waste is ingested by marine life, causing entanglement and toxic impacts. Recent studies have found over 170 trillion plastic particles afloat in the world's oceans, resulting in an estimated $13 billion in annual environmental damage to marine ecosystems.
Freshwater ecosystems are also impacted by plastic pollution. Rivers act as conveyor belts, carrying plastic waste from land to the sea. Even when plastic waste remains in freshwater ecosystems, it can still harm local wildlife and contaminate water sources. Plastic pollution can alter habitats and natural processes, reducing ecosystems' ability to adapt to climate change and provide essential services to humanity.
Terrestrial ecosystems are not immune to plastic pollution either. Improperly discarded plastic waste can pollute soil and release toxic chemicals. Incineration of plastic waste releases toxic chemicals and microplastics into the air, while landfills contaminate the soil. Plastic pollution can also transport invasive alien species, which contribute to biodiversity loss and species extinction.
The impacts of plastic pollution on biodiversity are far-reaching. Wildlife, including birds, whales, fish, and turtles, mistake plastic waste for food, leading to starvation and internal injuries. Farm animals are also affected, and the ingestion of plastic by livestock can have indirect consequences for human health. With plastic pollution affecting all ecosystems, driving biodiversity loss, it is essential to address this global issue through improved waste management, recycling, and reduced production of single-use plastics.

Climate Change: plastic production and pollution contribute to emissions
Plastic pollution is a global problem that affects millions of people, ecosystems, and wildlife. It is estimated that every day, the equivalent of 2,000 garbage trucks full of plastic are dumped into the world's oceans, rivers, and lakes, with 19-23 million tonnes of plastic waste leaking into aquatic ecosystems annually. This plastic waste comes primarily from middle-income countries, particularly in Asia, where waste management infrastructure is often lacking. As a result, plastic pollution has become ubiquitous in natural and built environments, with microplastics found in every ecosystem on the planet, from the Antarctic tundra to tropical coral reefs.
The production and incineration of single-use plastics contribute significantly to climate change by emitting vast amounts of greenhouse gases at every stage of their life cycle. The extraction and transportation of fossil fuels used to create plastics emit 1.5 to 12.5 million metric tons of greenhouse gases annually. Additionally, the removal of forested land for oil extraction and pipeline construction has released over 1.6 billion metric tons of carbon dioxide into the atmosphere, reducing the planet's ability to absorb carbon dioxide. The refinement of plastics emits an additional 184 to 213 million metric tons of greenhouse gases each year. Landfills, where a significant portion of single-use plastics end up, account for more than 15% of methane emissions, further contributing to climate change.
The rapid growth of the global plastics industry, fueled by natural gas, undermines efforts to reduce carbon pollution. Projections indicate that without intervention, the global plastics industry will account for 20% of total oil consumption and up to 15% of global carbon emissions by 2050. This reliance on plastics will have a significant climate impact, with greenhouse gas emissions from plastics projected to increase to 49 million metric tons by 2030 and 91 million metric tons by 2050.
To address this issue, a transition towards ""zero waste"" is recommended, emphasizing responsible production, consumption, reuse, and recovery of materials without incineration or landfilling. This will require a significant cultural shift and improvements in waste management infrastructure, particularly in low-to-middle-income countries. By reducing the overall use of plastic and eliminating unnecessary plastics, we can jointly tackle the climate and plastic pollution crises.

Economies: plastic litter impacts trade, income, and sectors like tourism and agriculture
Plastic waste has far-reaching economic impacts, affecting trade, income, and sectors such as tourism and agriculture. Marine plastic pollution poses a significant threat to economies, particularly those of coastal nations and islands that are heavily dependent on tourism. The presence of plastic litter on beaches and in the ocean reduces tourism revenues, as people are less inclined to visit areas affected by plastic pollution. This decrease in tourism has a direct impact on the income and livelihoods of local communities, businesses, and industries that rely on tourism for their economic well-being.
The fishing industry, a vital source of income for many coastal communities and countries, is also adversely affected by plastic waste. Marine plastic pollution harms fisheries through dumped catch, fouling incidents, net repairs, and time lost cleaning nets. Additionally, ghost fishing, where lost or abandoned fishing gear continues to trap and kill fish, can lead to further revenue losses for the fishing industry. Plastic pollution also impacts fish themselves, as they ingest plastic waste, potentially leading to health issues and affecting the provision of fisheries as an ecosystem service.
The economic repercussions of plastic pollution extend beyond the tourism and fishing sectors. Plastic waste can contaminate agricultural land and water resources, impacting the productivity and economic output of the agriculture industry. This is especially concerning in low and middle-income countries, where plastic pollution has outpaced the development of waste management infrastructure. The accumulation of plastic waste can have detrimental effects on local ecosystems, leading to environmental degradation and loss of ecosystem services that are crucial for sustainable economic development.
The financial damage caused by plastic pollution to marine ecosystems is significant, amounting to an estimated US$13 billion each year. This economic impact is felt across various sectors and underscores the importance of implementing effective plastic waste management practices. By reducing, recycling, and redesigning plastic products, economies can mitigate the environmental and economic costs associated with plastic pollution while also fostering innovation and bringing about green economy benefits.
