Plastic pollution is a pressing global issue that affects all ecosystems, from the Antarctic tundra to tropical coral reefs. It is caused by the improper disposal of plastic waste, which breaks down into microplastics and nanoplastics, persisting in the environment for centuries. Plastic pollution has severe ecological, economic, and health impacts, threatening biodiversity, altering habitats, and causing potential harm to humans and wildlife through ingestion, suffocation, or entanglement. Addressing this crisis requires collective action on a global scale, including reducing plastic production, improving waste management, adopting circular economy solutions, and implementing international agreements and policies to curb plastic pollution.

What You'll Learn
Plastic in natural ecosystems
Plastic pollution has become a ubiquitous issue in natural and built environments, with single-use plastic products being a major contributor. These products, such as plastic bags, bottles, straws, and food wrappers, have a very short lifespan but can persist in the environment for hundreds of years. The throw-away culture associated with these products has led to an overwhelming rise in plastic pollution, with garbage collection systems in many developing nations being inefficient or non-existent.
The impact of plastic pollution is felt across all ecosystems, including land, freshwater, and marine environments. Rivers play a significant role in transporting plastic waste to the oceans, with more than 1000 rivers accounting for 80% of global plastic emissions into the sea. Once in the ocean, plastic pollution can spread worldwide through ocean currents. Marine plastic pollution breaks down into microplastics and nanoplastics due to natural factors like sunlight, wind, and waves. These small plastic particles have been found in every ecosystem, from the Antarctic tundra to tropical coral reefs.
The presence of plastic in natural ecosystems has severe consequences for wildlife and the environment. Animals, including birds, whales, fish, and turtles, mistake plastic waste for food, leading to ingestion, suffocation, and entanglement. Floating plastics also contribute to the spread of invasive alien species, causing biodiversity loss and species extinction. Additionally, plastic pollution can release toxic chemicals into the soil and water, impacting the health of species that come into contact with these contaminants.
To address plastic pollution in natural ecosystems, it is crucial to focus on waste management, recycling, and reducing single-use plastic production. The circularity of supply and value chains needs to be improved, and consumer behaviour must change to reduce the use of disposable plastic products. Ambitious reductions in plastic production, phasing out harmful products, and implementing strong national plans and compliance mechanisms are essential steps towards mitigating the impact of plastic pollution on natural ecosystems.

Microplastics in the human body
Plastic pollution has become a ubiquitous issue, affecting natural and built environments alike. Plastic pollution can fragment into smaller pieces, known as microplastics, which range in size from five millimetres to one nanometre. These microplastics are pervasive across ecosystems and present a growing concern for human health.
Microplastics can enter the human body through ingestion, inhalation, or skin contact. Inhalation is of particular concern, as these particles can reach deep into the lungs, potentially causing lung disease. Microplastics have also been detected in the human spleen, liver, kidneys, placenta, and lungs. While the exact entry routes and health effects are still being researched, microplastics have been identified as potential vectors for pollutants and chemicals, facilitating their entry into human tissues.
Studies have shown that microplastics contain toxic chemicals, such as phthalates and BPA, which have been linked to serious health issues, including cancer, developmental and reproductive disorders, and cardiovascular problems. The presence of microplastics in the body may also contribute to oxidative stress and the production of reactive oxygen species (ROS), further exacerbating health risks.
To reduce exposure to microplastics, individuals can take measures such as avoiding disposable plastic water bottles, plastic containers for food storage and microwaving, and plastic cutting boards. Regular dusting and vacuuming can also minimise the presence of microplastic fibres in the home environment.

Global plastic treaties
Plastic pollution is ubiquitous in natural and built environments, threatening both human and natural ecosystems. It is a major driver of biodiversity loss, ecosystem degradation, and climate change. Plastic pollution is transboundary, meaning it does not respect national borders and is a global issue that requires a global solution. This is where global plastic treaties come in.
The United Nations Environment Programme (UNEP) and the Intergovernmental Negotiating Committee (INC) are leading efforts to develop a legally binding global plastic treaty. The process began in 2022 with the first intergovernmental negotiating meeting (INC-1) in Punta del Este, Uruguay, where more than 145 countries expressed support for strong global rules to stop plastic pollution. This was followed by INC-2 in Paris, France, and INC-3 in Nairobi, Kenya, where negotiations continued and a “zero draft" of the treaty was published.
The "zero draft" sets the stage for further negotiations and includes rules to prohibit problematic and avoidable plastic products. However, it remains to be seen whether the treaty will include measures to reduce plastic production and consumption. Civil society groups, nongovernmental organizations, and businesses have also urged UN member states to negotiate a legally binding treaty, with over 700 groups from 113 countries signing a Civil Society Manifesto.

Single-use plastics
Plastic pollution is everywhere, from Mount Everest to the Mariana Trench, and it is having a devastating impact on the environment and wildlife. Single-use plastics, in particular, are a major culprit, making up 40% of all plastic produced annually. These are plastics designed for one-time use, such as water bottles, soda bottles, plastic bags, product packaging, straws, coffee cups, and plastic baggies. They are often not recycled due to their small size and the fact that many recycling centres do not accept them. As a result, they end up in landfills, incinerators, or the environment, where they can persist for hundreds of years.
The production of single-use plastics is also contributing to climate change. They are derived from fossil fuels, and the extraction and manufacturing processes emit vast amounts of greenhouse gases. The shift towards single-use plastics, away from durable plastics, has been driven by convenience and a throw-away culture. This has resulted in an overwhelming rise in plastic waste, with more than 300 million tons of plastic waste produced yearly.
The best way to reduce plastic pollution is to prevent plastics from entering waterways and improve waste management systems. Recycling and product design are also crucial, as well as reducing the manufacturing of single-use plastics. Some companies are piloting reuse and refill systems, and governments are also taking action, with dozens of countries adopting policies to reduce disposable plastic use. Africa stands out as a continent where most countries have banned the production and use of plastic bags.
Microplastics, which are smaller than 5mm, are another concern. They are shed by synthetic textiles and tyres and are now found everywhere, including in our food supply. One study found microplastics in 90% of 16 types of commonly consumed proteins. The impact of microplastics on human health is still being understood, but exposure to certain chemicals in plastics is known to cause hormonal imbalances, reproductive problems, and even cancer.
To address plastic pollution, it is essential to reduce the number of plastic products made, increase the circularity of supply and value chains, and change consumer behaviour. This includes using reusable water bottles, bags, and containers, and avoiding overly packaged items. By taking action, we can reduce the devastating impacts of plastic pollution on our planet and our health.

Plastic waste in oceans
Plastic pollution in oceans has detrimental effects on marine life, leading to ingestion, suffocation, and entanglement. Marine species mistake plastic waste for food, filling their stomachs and causing starvation. Microplastics, due to their small size, are often consumed by marine organisms and can enter the food chain, eventually reaching humans. These microplastics have been found in human livers, kidneys, and placentas, raising concerns about potential health impacts.
The sources of oceanic plastic pollution are primarily land-based, including urban and stormwater runoff, littering, industrial activities, tyre abrasion, construction, and agriculture. Asia is a significant contributor, with China, Indonesia, the Philippines, and other countries being the largest emitters. Plastic waste is also generated by marine activities, such as discarded fishing gear and paint shed from shipping.
Addressing plastic waste in oceans requires a multifaceted approach. It involves reducing plastic production and consumption, improving recycling practices, and promoting circular economy solutions like reuse and refill. Global cooperation between governments, industries, scientists, and consumers is essential to tackle this issue effectively.
While some countries have implemented bans on certain single-use plastics, a global plastics treaty is necessary to reduce plastic production, phase out harmful practices, and protect marine ecosystems from the detrimental effects of plastic pollution. The impacts of plastic waste in oceans highlight the urgent need for collective action to preserve the health of our oceans and the countless species that depend on them.
