Plastic pollution is a global crisis. It is found all over the world, from Mount Everest to the Mariana Trench, and is negatively impacting biodiversity, climate change, human health, and human rights. The average person ingests approximately 5 grams of plastic weekly, and microplastics have been found in human blood, placentas, food, drinks, and the air. Plastic pollution is threatening wildlife, with millions of animals killed by plastics every year, and nearly 2,100 species, including endangered ones, affected. It is also altering habitats and natural processes, reducing ecosystems' ability to adapt to climate change, and directly affecting millions of people's livelihoods, food production, and social well-being.

Plastic waste is traded and shipped overseas, polluting the ocean
Plastic pollution is a pressing global issue, with an estimated one to two million tonnes of plastic entering our oceans each year. This plastic waste comes from a variety of sources, including litter in parks, beaches, and streets, which is then carried into drains, streams, and rivers. Additionally, a significant amount of plastic pollution in the oceans comes from marine sources such as fishing nets and lines.
While many countries ship plastic waste overseas, the impact of this practice on ocean pollution is complex. Rich countries are often net exporters of plastic waste, sending it to low-to-middle-income countries with poorer waste management systems. However, it is important to note that most of the waste that enters the oceans originates from these low-to-middle-income countries, highlighting the critical need to improve waste management practices in these regions.
The contribution of traded plastic waste to ocean pollution is estimated to be around 5%. While banning the export of plastic waste from rich countries to those with poor waste management could reduce pollution by up to 5%, it would not completely solve the issue. Only a small fraction of the world's plastic waste is traded, and the majority of traded waste ends up in richer countries where it is unlikely to reach the ocean.
To effectively tackle plastic pollution, a two-pronged approach is necessary. Firstly, rich countries should scale their waste management systems and invest in improving waste management infrastructure and practices in low-to-middle-income countries. Secondly, the management of plastic waste must be improved worldwide, especially in poorer countries where most ocean plastics originate. This includes recycling, incinerating, or properly disposing of plastic waste to prevent it from polluting the environment and entering our oceans.
The plastic pollution crisis requires a systemic transformation towards a circular economy. Plastic waste is not only detrimental to the environment but also poses risks to human and animal health. Microplastics, for example, have been found in municipal drinking water systems and are present in human blood, lungs, and feces. Addressing plastic pollution is crucial for the well-being of ecosystems and the millions of people whose livelihoods and food production capabilities are impacted.

Plastic waste is ingested by wildlife, causing starvation and injury
Plastic pollution is a global problem. Every year, about eight million tons of plastic waste escape into the oceans from coastal nations, polluting lakes, rivers, and seas. This is the equivalent of setting five garbage bags of trash on every foot of coastline around the world. Once in the ocean, plastic waste can spread worldwide, carried by ocean currents.
Plastic pollution is not limited to the oceans. Land-based animals, including elephants, hyenas, zebras, tigers, camels, cattle, and other large mammals, have consumed plastic, in some cases leading to death. Plastic ingestion has been found to cause liver and cell damage and disrupt reproductive systems.
The impact of plastic pollution extends beyond wildlife. Microplastics have been detected in municipal drinking water systems and have been found in human blood, lungs, and even feces. While the health effects of microplastics are still being studied, several chemicals used in plastic production are known to be carcinogenic and can cause developmental, reproductive, neurological, and immune disorders.
To address plastic pollution, improved waste management systems, better product design, and a reduction in single-use plastics are crucial. While recycling is important, it is not sufficient to solve the plastic pollution crisis. A systemic transformation is necessary to transition to a circular economy and reduce the vast amounts of plastic waste entering our oceans and other ecosystems.

Microplastics are in our blood, lungs, and food and drinks
Plastic pollution is a pressing issue, with plastic waste dumped across the planet, from Mount Everest to the deepest oceans. Mismanaged plastic waste is a significant contributor to this problem, with a large portion of waste neither recycled nor disposed of properly. This waste breaks down into microplastics, tiny plastic particles that contaminate our environment and our bodies.
Recent studies have found microplastics in human blood for the first time, with plastic particles detected in the blood samples of healthy adult donors. These particles can travel through the body and may lodge in organs, including the brain. The presence of microplastics in the body has been linked to an increased risk of cardiovascular events, as well as inflammation, immune dysregulation, and metabolic disruptions. While the specific health impacts are still being researched, the absence of established safety thresholds for microplastic levels in the body indicates that this is a cause for concern.
Microplastics have also been identified in human lung tissue, with higher levels found in lung tissue samples from industrial settings, suggesting that inhalation is a significant route of exposure. Airborne microplastic concentrations are known to be higher in areas of high human population and activity, particularly indoors.
In addition to inhalation, microplastics enter our bodies through the food and water we consume. Filter-feeding shellfish, such as shrimp, mussels, clams, and oysters, are known to accumulate microplastics from their environment, which are then passed on to consumers. Instant rice and washed rice have also been found to contain significant amounts of plastic. To minimise microplastic exposure, experts recommend opting for filtered tap water stored in stainless steel or glass containers and diversifying protein sources to include plant-based proteins, poultry, and sustainably sourced fish.

Plastic production increased from 2.3 million tons in 1950 to 448 million tons by 2015
Plastic is a cheap, versatile, and durable material that has added a lot of value to our lives. It is used in various applications, including construction, home appliances, medical instruments, and food packaging. However, the exponential increase in plastic production has had a detrimental effect on our planet.
Plastic production has increased significantly over the last few decades, with the annual production of plastics increasing nearly 230-fold in 70 years. Specifically, plastic production increased from 2.3 million tons in 1950 to 448 million tons by 2015. This rapid growth in plastic production has contributed to the plastic pollution crisis the world is facing today.
The high durability of plastics, which is often enhanced by additives, is a double-edged sword. While it is beneficial for the intended use of the plastic product, it becomes a problem when the product becomes litter. Plastic waste can take at least 400 years to break down, and during this time, it can cause significant harm to the environment and ecosystems.
Every year, about eight million tons of plastic waste escape into the oceans from coastal nations. This waste is often carried by major rivers, acting as conveyor belts, and ends up polluting lakes, rivers, and seas. Plastic pollution can alter habitats and natural processes, affecting the ability of ecosystems to adapt to climate change. It also directly impacts the livelihoods, food production capabilities, and social well-being of millions of people.
The plastic pollution crisis requires a systemic transformation towards a circular economy. While reducing plastic production is important, the more critical issue is improving the management of plastic waste. Domestic policies and foreign investments in waste management infrastructure are crucial to addressing the plastic pollution crisis effectively.

Plastic pollution threatens human health and the environment
Plastic pollution is a global problem. Every year, about 19 to 23 million tons of plastic waste leaks into aquatic ecosystems, polluting lakes, rivers, and seas. This waste primarily comes from single-use plastic products, such as bottles, caps, bags, cups, and straws. The impact of this waste is felt across the world, threatening human health, wildlife, and the environment.
Plastic waste is ingested by wildlife, causing internal injuries, reducing their ability to swim and fly, and leading to starvation as their stomachs become filled with indigestible plastic. It is estimated that millions of animals, including nearly 2,100 species of endangered wildlife, are killed by plastic pollution annually. Plastic pollution also affects domesticated farm animals and facilitates the spread of invasive species, a leading cause of biodiversity loss and species extinction.
In addition to the harm caused to wildlife, plastic pollution has severe impacts on human health. Microplastics, which are plastic particles smaller than 5mm, have been found in human blood, lungs, placentas, and even feces. These microplastics can cause a range of health issues, including cardiovascular disease, chronic kidney disease, birth defects, and cancer. They can also act as vessels for pathogens, increasing the spread of diseases. The toxic chemical additives and pollutants found in plastics, such as carcinogens, have been linked to developmental, reproductive, neurological, and immune disorders.
The environmental impact of plastic pollution is also significant. Plastic debris can alter habitats and natural processes, reducing ecosystems' ability to adapt to climate change. It can also release carcinogenic chemicals into the soil, which can then run into groundwater or rivers, affecting both human and wildlife ecosystems. Furthermore, the production of plastics contributes to climate change, as it involves the extraction of fossil fuels and the use of refining processes.
To address the threat of plastic pollution, effective waste management is crucial. Currently, only 9% of plastic waste is recycled globally, with half going straight to landfills and a significant portion being mismanaged. Improving waste management practices and reducing plastic production can help mitigate the negative impacts of plastic pollution on human health and the environment.
