What You'll Learn
Plastics are derived from fossil fuels and contribute to climate change
Plastics are derived from fossil fuels, such as natural gas, crude oil, gas, and petroleum, and their production and disposal contribute to climate change. The extraction and creation of plastics emit vast amounts of greenhouse gases. The refinement of plastics emits an additional 184 to 213 million metric tons of greenhouse gases each year. Landfills, where single-use plastics often end up, account for more than 15% of methane emissions.
The production of plastics is closely tied to the extraction of fossil fuels. 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. This land clearing also limits the amount of carbon dioxide that can be removed from the atmosphere.
The global plastic problem is pervasive, with plastic waste reaching every corner of the planet, from Mount Everest to the Mariana Trench. Plastic pollution is persistent and can take anywhere from 100 to over 1,000 years to decompose, depending on environmental conditions. During this slow decomposition process, plastic can fragment into smaller pieces, known as microplastics and nanoplastics, which are found in every ecosystem on Earth.
Microplastics, ranging in size from five millimeters to one nanometer, and nanoplastics, smaller than one micrometer, pose a significant threat to marine life. Marine species are at high risk of ingesting plastic, suffocating, or becoming entangled in plastic pollution. More than 1,500 species in marine and terrestrial environments are known to ingest plastics, and this number is expected to increase.
The impact of plastic pollution extends beyond the environment and has significant implications for human health. Humans are exposed to toxic chemicals and microplastics through inhalation, ingestion, and direct skin contact. Scientific research indicates that exposure to plastics can cause diseases, disabilities, and premature death. The toxic chemical additives and pollutants found in plastics have been linked to endocrine disruption, reproductive issues, growth impairment, and cognitive problems.

Plastics pollute the seas, land and air
Plastic pollution is a pressing issue that affects the seas, land, and air. It is a major contributor to biodiversity loss, ecosystem degradation, and climate change. With over 460 million metric tons of plastic produced annually and an estimated 20 million metric tons of plastic litter ending up in the environment, plastic pollution has become ubiquitous.
Plastics pollute the seas primarily through land runoff, paint shed from shipping, discarded fishing gear, and synthetic textiles. It is estimated that 85% of marine litter originates from land-based sources, and this has severe consequences for marine life. Marine species are at higher risk of ingesting plastic, suffocating, or becoming entangled in plastic pollution. The ingestion of plastics can lead to the ingestion of toxic chemicals, which can cause developmental, reproductive, neurological, and immune disorders. Furthermore, plastic pollution in the oceans contributes to the growing issue of microplastics and nanoplastics, which are plastic particles smaller than five millimeters and one micrometer, respectively. These microplastics and nanoplastics are ingested by marine organisms and can accumulate in their bodies, potentially leading to unknown health effects.
On land, plastic pollution is prevalent through littering, industrial activities, construction, and agriculture. The durability of plastics means that discarded items can remain in the environment for generations, leading to the contamination of ecosystems and the food chain. Microplastics have been found in human food and drinks, and their ingestion can have adverse health effects, including cancer, endocrine disruption, and reproductive, growth, and cognitive impairments. Landfills, where single-use plastics are often disposed of, account for more than 15% of methane emissions, contributing to air pollution and climate change.
The production and disposal of plastics also contribute to air pollution. The extraction and creation of single-use plastics emit vast amounts of greenhouse gases, and the refinement of plastics emits additional greenhouse gases. Additionally, the incineration of plastic waste releases toxic chemicals into the air, further contributing to air pollution and posing risks to human health. The global trade of plastic products and waste exacerbates the issue, as plastic waste is often sent to locations lacking sufficient infrastructure for safe and environmentally sound management.

Plastics contaminate the food chain and water supply
Plastic pollution is a pressing issue that poses a significant threat to both the environment and human health. With over 460 million metric tons of plastic produced annually and an estimated 20 million metric tons of plastic polluting the environment each year, the impact of plastic on the food chain and water supply is a growing concern.
Plastics contaminate the food chain through the release of microplastics and nanoplastics into ecosystems. Microplastics, ranging in size from five millimeters to one nanometer, and nanoplastics, smaller than one micrometer, are pervasive in every ecosystem, from the Antarctic tundra to coral reefs. These tiny plastic particles can be ingested by organisms, leading to bioaccumulation and potential health risks. Research indicates that more than 1,500 species in marine and terrestrial environments ingest plastics, contributing to the contamination of the food chain.
The presence of microplastics and nanoplastics in water supplies is a significant concern. These particles have been detected in tap water, demonstrating their ability to infiltrate water sources intended for human consumption. The infiltration of microplastics and nanoplastics into water supplies can occur through various pathways, including runoff from land, industrial activities, and improper waste management.
The health impacts of ingesting microplastics and nanoplastics are still being studied, but initial findings indicate potential risks. While the full extent of their impact on human health is not yet fully understood, studies suggest that these plastic particles can act as a vector for toxic chemicals, including endocrine disruptors, which can lead to reproductive, growth, and cognitive impairments. The ubiquity of plastics and the potential for human exposure through the food chain and water supply highlight the urgency of addressing plastic pollution to safeguard human health and the environment.
Furthermore, the production and disposal of plastics contribute to climate change, which indirectly affects the food chain and water supply. The extraction and creation of plastics emit vast amounts of greenhouse gases, and the refinement process releases additional emissions. Landfills, where single-use plastics often end up, contribute significantly to methane emissions. Climate change impacts weather patterns, influencing water availability and agricultural productivity, which, in turn, affect the food chain and water supply.

Plastics have severe health impacts on humans and animals
Plastic pollution is a pressing issue that poses severe health risks to both humans and animals. It is pervasive in natural and built environments, with microplastics and nanoplastics present in every ecosystem, from the Antarctic tundra to tropical coral reefs. The persistence of plastic pollution, which can take hundreds to thousands of years to decompose, exacerbates its detrimental impact on health.
Effects on Humans
Humans are exposed to toxic chemicals and microplastics through inhalation, ingestion, and direct skin contact. The average person may ingest approximately 0.1 to 5 grams of plastic per week, with inhalation rates reaching up to 22,000,000 micro- and nanoplastics annually. These plastic particles can cross the gut barrier and travel through the body, causing harmful effects. Scientific studies indicate that exposure to plastics contributes to various diseases, disabilities, and premature deaths. The toxic chemical additives in plastics can cause cancer and disrupt hormones (endocrine disruption), leading to reproductive abnormalities, growth, and cognitive impairments. Vulnerable groups, including children, women, and marginalized communities, are particularly at risk, with increased chances of prematurity, stillbirth, birth defects, neurodevelopmental issues, impaired lung growth, and childhood cancer.
Effects on Animals
Plastic pollution severely impacts wildlife, including marine, terrestrial, and aquatic species. Over 1,500 species in marine and terrestrial environments are known to ingest plastics, leading to physical problems and even death. Microplastics contaminate soil and water sources, threatening the survival of smaller creatures like mites, larvae, and other invertebrates. Chlorinated plastic can release harmful chemicals into the soil and groundwater, further endangering wildlife that relies on these resources. Additionally, marine species face higher risks of suffocation or entanglement in plastic waste, contributing to the decline of biodiversity.
The pervasive nature of plastic pollution and its severe health impacts on humans and animals underscores the urgency of addressing this global crisis. With plastic production and consumption continuing to rise, sustainable practices, improved disposal methods, and international collaboration are essential to mitigate the detrimental effects of plastic pollution on health and the environment.

Plastics are persistent and do not decompose for hundreds of years
Plastic is a relatively new invention, with the first examples dating back to the late 1800s. However, its durability has led to a persistent environmental problem. Plastic does not decompose for hundreds, if not thousands, of years, with estimates ranging from 100 to over 1,000 years. This means that every plastic bottle, straw, and container ever thrown away is still intact somewhere on Earth.
The durability of plastics means that discarded items remain in the environment for generations, with plastic pollution found in every ecosystem on the planet, from the Antarctic tundra to tropical coral reefs. Plastic pollution is a transboundary issue, affecting all land, freshwater, and marine ecosystems. It is a major driver of biodiversity loss, contributing to the more than 1,500 species in marine and terrestrial environments known to ingest plastics. Plastic can fragment into smaller pieces, known as microplastics and nanoplastics, which are found in every ecosystem. These microplastics can end up in the human body, with unknown health effects, although initial research indicates they can cause diseases, disabilities, and premature death.
The persistence of plastics in the environment is due to their synthetic, organic polymer composition, derived from fossil fuels such as natural gas, crude oil, gas, and petroleum. The extraction and creation of these plastics emit vast amounts of greenhouse gases, contributing to climate change. The refinement of plastics emits an additional 184 to 213 million metric tons of greenhouse gases each year. Landfills, where single-use plastics often end up, account for more than 15% of methane emissions.
The global trade of plastic products and waste exacerbates the issue, as plastic waste is often sent to locations lacking the infrastructure for safe and environmentally sound management. This disproportionately impacts islands, developing countries, Indigenous peoples, local communities, women, and children. The environmental, social, and economic risks of plastics are far-reaching, and the annual emissions related to plastic production in the EU amount to around 13.4 million tonnes of CO2.
The persistence of plastics in the environment is a critical issue, with plastic waste accumulating in the environment at an alarming rate. The global consumption of plastic is accelerating, and plastic pollution poses a long-term threat to ecosystems and human health.
