The Atlantic's Plastic Problem: An Ominous Overview

Plastic pollution in the ocean is a pressing issue, with scientists warning that there will be more plastic in the ocean than fish by 2050. While the exact amount of plastic in the Atlantic Ocean is unknown, studies indicate that the scale of the problem is far greater than previously thought. Research has revealed high concentrations of microplastics below the ocean's surface, threatening marine life and human health. With plastic production expected to increase, addressing this issue is crucial to safeguard our oceans and ecosystems.

The Atlantic's total plastic load is estimated to be 200 million metric tons

The Atlantic Ocean is one of the five oceans contaminated with plastic pollution. A recent study published in Nature Communications in 2020 revealed that the Atlantic's total plastic load is estimated to be 200 million metric tons, which is approximately 220.4 million US tons. This estimate is 10 times more than previously predicted, with earlier estimates suggesting that the Atlantic Ocean held between 17 million and 47 million tons of plastic released between 1950 and 2015.

The 2020 study, led by Katsiaryna Pabortsava from the National Oceanography Centre in the United Kingdom, focused on the three most common and polluted types of plastic: polyethylene, polypropylene, and polystyrene. These three types of plastic are commonly used in food packaging and other products. The study analyzed seawater samples collected from 12 locations across the Atlantic Ocean between September and November 2016.

The findings highlight a critical need to reassess the impact of plastic contamination on the ocean environment and human health. The study also emphasizes the importance of improving waste management practices to reduce the amount of plastic entering our oceans.

While the 2020 study provides valuable insights, the exact amount and location of plastic pollution in the Atlantic Ocean remain largely unknown. The impact of plastic contamination on the ocean ecosystem and human health is a growing concern, and further research is needed to fully understand the extent of the problem and develop effective solutions.

To address the issue of plastic pollution in the Atlantic and other oceans, it is crucial to reduce plastic use, improve waste management practices, and participate in cleanup efforts. By raising awareness, implementing sustainable alternatives, and supporting initiatives that tackle plastic pollution, we can collectively work towards mitigating the harmful effects of plastic waste on our oceans and the environment.

Microplastics are found in sea animals, including turtles

The amount of plastic in the Atlantic Ocean is difficult to determine, but it is estimated that there are 21,000 pieces of plastic floating in the ocean for every person on the planet. The problem is only growing, with around 300 million plastic bags entering the Atlantic Ocean annually, and plastic production expected to increase over the next decade.

Microplastics, small plastic pieces less than 5mm in size, are a significant concern in the Atlantic Ocean and other marine environments. They are generated directly for commercial purposes and indirectly from the breakdown of larger plastics. These microplastics can enter the ocean through a range of land and sea sources, including river runoff, disposable fishing gear, plastic cages, packages, and buoys.

Sea turtles are among the marine animals affected by microplastics. Studies have found microplastics in the digestive contents of sea turtles' guts, with concentrations ranging from 2.5 to 12.5 particles per turtle. The polymer composition of these microplastics includes polyethylene, polypropylene, polystyrene, and other synthetic materials.

The presence of microplastics in sea turtles has raised concerns about potential bioaccumulation and biomagnification in the trophic chain. Sea turtles share similar marine trophic chains with humans, making them valuable indicators of the potential human health risks associated with microplastic ingestion.

In addition to sea turtles, over 220 species of marine animals (excluding birds) have been found to ingest microplastics. This has increased the risk of human consumption of microplastics, as half of these species are relevant for commercial purposes.

The number of plastic particles in the sea doubles every six years

The number of plastic particles in the sea is a pressing issue that threatens marine life and human health. According to the Washington Post, the number of plastic particles in the sea doubles every six years. This alarming rate of increase was revealed in a study conducted by a team of international researchers led by Marcus Eriksen of the 5 Gyres Institute. The study, published in the PLOS One journal, analyzed nearly 12,000 samples collected over 40 years from all the world's major ocean basins.

The findings of the study highlight a concerning trend in plastic pollution. Researchers observed a significant rise in plastic pollution starting in 2004, coinciding with an increase in plastic production globally. This trend indicates that the amount of plastic entering our oceans is rapidly growing, and once in the water, it can travel long distances. The weight of the plastic particles in the ocean is estimated to be around 2.4 million metric tons, equivalent to about 28 Washington Monuments.

The impact of plastic pollution is far-reaching. It affects not only the health of our oceans and aquatic life but also human health. With poor waste management and littering, plastic waste makes its way into rivers and the sea. Once in the ocean, plastic can break down into tiny pieces called microplastics, which can be ingested by marine life and absorb harmful pollutants. These microplastics, measuring less than 5 millimeters in length, are difficult to detect and remove from the ocean.

The Atlantic Ocean, like other major ocean basins, is significantly affected by plastic pollution. Studies have revealed high concentrations of plastic hidden beneath the surface of the Atlantic, with quantities greater than previously estimated. The mass imbalance between the plastic litter supplied and observed in the ocean indicates a missing sink, suggesting that the true extent of plastic pollution may be even worse than what we currently observe.

As plastic production is expected to increase over the next decade, the issue of plastic pollution in the Atlantic and other oceans will only become more dire. It is crucial to address this problem through improved waste management, reduced plastic use, and participation in cleanup efforts to minimize the impact of plastic pollution on our oceans and the environment.

300 million plastic bags enter the Atlantic Ocean annually

The Atlantic Ocean is one of the five oceans that contain massive patches of garbage, according to the National Oceanic and Atmospheric Administration (NOAA). The Great Pacific Garbage Patch, located in the Pacific Ocean, is the most infamous, believed to be around three times the size of France.

The Atlantic Ocean is not exempt from this issue, with around 300 million plastic bags entering it every year. This is part of a wider problem, with humans using an estimated 5 trillion plastic bags annually, of which less than 1% are recycled. The fate of these plastic bags is often ingestion by marine life or breaking down into small fragments. This is a critical issue, as scientists believe that over 50% of all marine life has ingested plastic.

Plastic bags are not the only plastic waste entering the ocean. Plastic bottles, fishing nets, food wrappers, straws, and take-out containers are also common forms of plastic waste. The impact of plastic waste on the ocean is severe, with plastic jeopardizing marine life, aquatic life, and human health. Furthermore, the mass-imbalance between the plastic litter supplied to and observed in the ocean indicates a missing sink, with high loads of small-sized plastic debris concealed below the ocean surface.

The plastic crisis is not limited to the Atlantic Ocean. It is a global issue, with plastic waste affecting all five oceans. The exact amount of plastic in the ocean is challenging to determine, but it is estimated that 8 million metric tons of plastic entered the ocean in 2010, and this problem continues to grow. With plastic production expected to double in the next decade, the amount of plastic entering the ocean will likely increase unless drastic action is taken.

The fate of plastics once they enter the ocean is a puzzle for researchers

The amount of plastic in the ocean is a pressing environmental issue. While the exact quantity of plastic in the ocean is uncertain, it is estimated that around 0.5% of the world's plastic waste ends up in the ocean, which equates to around 6 million tonnes. This waste predominantly originates from land, with nearly one-quarter of plastic waste being mismanaged or littered.

The plastic that does make its way into the ocean has a devastating impact on marine life and ecosystems. It can cause damage to animals through suffocation, entanglement, laceration, infection, and internal injury. Plastic can also transport invasive species, threatening marine ecosystems, biodiversity, and the food web. Microplastics, in particular, are consumed by marine animals, entering the food chain and leading to disastrous health consequences for the planet and its inhabitants.

The risks posed by plastic contamination are challenging to assess as the amount and location of plastic in the ocean remain largely unknown. However, studies have shown that the ocean interior contains high loads of small-sized plastic debris, with the combined mass of certain plastics in the top 200 meters of the Atlantic Ocean alone being between 11.6 and 21.1 million tonnes.

The best solution to the issue of plastic in the ocean is to prevent plastic waste from entering rivers and seas in the first place. This can be achieved through improved waste management systems, increased recycling, and the reduction of single-use plastic manufacturing.
