When Mermaids Cry: The Great Plastic Tide is an article by Claire Le Guern Lytle that discusses the plastic pollution affecting our oceans, beaches, coasts, and seafloor. The article highlights the dramatic increase in plastic production and consumption over the last 50 years, with an estimated 299 million tons of plastic produced in 2013. This has led to an unprecedented plastic tide, with plastic debris washing up on shores and affecting marine life and ecosystems. The issue is exacerbated by people's inability to properly dispose of plastic waste, leading to pollution that originates from land and is carried by wind and rain into the sea. The consequences of this pollution are sobering, with marine animals ingesting plastic and experiencing harmful effects on their health and fertility rates. The article calls for a behavioural change in our relationship with plastics to address this crisis.

What You'll Learn
The plastic pollution spectacle
The impact of this plastic pollution goes beyond the immediate toxicity to marine life. Studies have shown that plastic is causing a decrease in the fertility rates of fish, as they ingest tiny plastic particles that harm their digestive systems. Additionally, the plastic pollution spectacle is a stark reminder of the long-lasting nature of plastic as a pollutant. Unlike natural pollutants like excess CO2 or methane, plastic is not biodegradable and cannot be assimilated into nature. Once plastic enters the marine environment, it persists for centuries, breaking down into microplastics that continue to inflict damage.
Addressing the plastic pollution spectacle requires a twofold approach: behavioural change and a reduction in plastic consumption and production. While it may be uncomfortable to confront the role of human activity in creating this crisis, it is essential to acknowledge our collective responsibility in driving the dramatic behavioural changes needed to limit the plastic tide. Additionally, we must advocate for a decrease in the global production and consumption of plastics, which has been steadily increasing for over 50 years. By tackling this issue at its source and in its manifestations, we can begin to stem the tide of plastic pollution and work towards a healthier, more sustainable future for our oceans and ourselves.

The Great Pacific Garbage Patch
The GPGP is one of five offshore plastic accumulation zones in the world's oceans. It covers an estimated surface area of 1.6 million square kilometres, twice the size of Texas or three times the size of France. The patch is made up of microplastics, tiny bits of plastic that are often microscopic and cannot be seen by the naked eye. These microplastics give the water a cloudy soup appearance and are intermixed with larger items such as fishing gear and shoes.
The plastic in the GPGP comes from a variety of sources, including land-based sources such as improper waste disposal and marine sources such as boats. A 2018 study reported that synthetic fishing nets made up nearly half the mass of the GPGP, and a 2022 study found that 75% to 86% of the plastic pollution in the patch came from fishing and agriculture, with the most identified emissions originating from Japan, China, South Korea, the US, and Taiwan.
The amount of debris in the GPGP continues to increase as more plastics are discarded into the environment. The plastic breaks down into smaller microplastics over time due to the effects of the sun, waves, and marine life, but it does not fully biodegrade. This means that the microplastic concentration in the GPGP will continue to grow, posing a significant threat to marine life and the environment.
The Ocean Cleanup organisation has been working to clean up the GPGP, and by the end of 2024, they had removed more than one million pounds of trash from the patch. However, the GPGP is believed to have increased rapidly, with a ten-fold increase each decade since 1945. The crisis is of massive proportions, with plastic pollution affecting the world's oceans, beaches, coasts, seafloor, and animals.

The South Gyre
The plastic pollution in the South Gyre has far-reaching consequences for the marine environment and beyond. Plastic particles can be ingested by marine organisms, affecting their fertility and causing blockages in their digestive systems. This has a detrimental impact on marine ecosystems, including fish and bird populations. For example, on Midway, bird corpses were found with intact stomach-sized piles of plastic, indicating that the plastic had caused their death.
The plastic pollution in the South Gyre is not an isolated issue. It is part of a global plastic pollution crisis affecting oceans, beaches, coasts, and seafloors worldwide. The plastic waste originates from human activities, including shoreline recreation, sewage, and fishing practices. With the world population increasingly congregating along coasts, the impact of plastic pollution on marine environments is likely to intensify.
Addressing the plastic pollution crisis, including the South Gyre, requires a significant behavioral change in our relationship with plastic. This includes reducing plastic consumption, properly disposing of plastic waste, and exploring alternatives to plastic that are more environmentally friendly and biodegradable. By taking action, we can help mitigate the devastating impact of plastic pollution on our oceans and the organisms that depend on them.

The health effects of plastic pollution
One of the primary ways humans are exposed to plastic pollution is through the food chain. Microplastics have been found in seafood, including fish and shellfish, as well as in tap water, bottled water, and even beverages like beer. A recent study estimates that the average adult consumes approximately 2,000 microplastics per year through salt alone. These microplastics can also carry toxic chemicals, which can leach into our bodies and have been linked to serious health issues. These include endocrine disruption, weight gain, insulin resistance, decreased reproductive health, and cancer.
In addition to the food chain, humans are also exposed to plastic pollution through the products we use daily, such as plastic water bottles, knives, and dermatological products. This exposure can also occur through plastic-based medical supplies and airborne plastic pollution. Recent studies have detected microplastics in human blood, lungs, and even the placenta, indicating that plastics can enter the human bloodstream and reside in our bodies permanently.
Vulnerable groups, including children, women, workers in the waste sector, and marginalized communities, are particularly at risk from the health effects of plastic pollution. For example, exposure to plastics during pregnancy has been linked to increased risks of prematurity, stillbirth, birth defects, impaired lung growth, and childhood cancer. Additionally, plastics contribute to the health risks associated with climate change, including warming temperatures and extreme weather events.
The impact of plastic pollution extends beyond human health, also affecting plant and animal life. For example, the "Great Plastic Tide" has resulted in unprecedented plastic waste in our oceans, on our beaches, and along our coasts, endangering marine life and the environment. With plastic production and consumption continuing to rise globally, it is crucial to address this issue through better management of plastics, a reduction in plastic usage, and a transition to a more sustainable economy.

The difference between atmospheric pollution and plastic pollution
The world is currently facing an unprecedented crisis in the form of plastic pollution. The oceans, beaches, coasts, seafloor, animals, and ultimately humans are all affected by this crisis. For more than 50 years, the global production and consumption of plastics have been steadily increasing. Plastic is versatile, lightweight, flexible, moisture-resistant, strong, and relatively inexpensive. However, it is not biodegradable and does not fully break down, instead forming microplastics that can last on Earth for centuries.
Plastic pollution is not limited to the oceans and beaches; it has also been found in the air we breathe. Recent studies have shown that tiny pieces of plastic, known as microplastics, are constantly being lofted into the atmosphere. These particles can travel thousands of miles and affect the formation of clouds, potentially impacting temperature, rainfall, and even climate change. While plastic pollution in the atmosphere is a concerning issue, it is important to distinguish it from atmospheric pollution, which refers to the contamination of the air by harmful gases and particles.
Atmospheric pollution, also known as air pollution, is primarily caused by human activities such as the combustion of fossil fuels, vehicle emissions, industrial processes, and agricultural activities. It includes pollutants such as carbon monoxide, sulfur dioxide, nitrogen oxides, particulate matter, and volatile organic compounds. These pollutants have detrimental effects on both human health and the environment, contributing to respiratory problems, cardiovascular diseases, and the formation of smog and acid rain. Unlike plastic pollution, atmospheric pollution does not involve the presence of physical particles like plastic debris or microplastics.
While plastic pollution and atmospheric pollution differ in their specific nature and causes, they are interconnected in some ways. For example, the production, incineration, and combustion of plastics contribute to atmospheric pollution by releasing greenhouse gases, particularly carbon dioxide (CO2). Studies have shown that plastic pollution-related emissions have a minor impact on atmospheric CO2 concentrations compared to fossil fuel combustion. However, the overall impact of plastic production and incineration on the climate is significant.
In conclusion, while atmospheric pollution and plastic pollution have distinct characteristics and sources, they are both critical environmental issues that require attention and action. Addressing these problems involves individual efforts, such as reducing plastic waste and advocating for green policies, as well as global initiatives to regulate plastic production and improve recycling practices. By understanding the differences between these two types of pollution, we can develop more effective strategies to mitigate their impacts and protect our planet for future generations.
