The Ocean's Plastic Crisis: How Much Is Reaching Our Seas?

Plastic pollution is a pressing issue that affects all ecosystems, including marine life. It is estimated that 8 million metric tons of plastic waste are dumped into our oceans annually, with a further 33 billion pounds of plastic entering the marine environment each year. This plastic waste comes from a variety of sources, including single-use products, microplastics, and abandoned fishing gear. The impact of plastic pollution is far-reaching, with over 1 million seabirds and 100,000 marine animals dying from plastic ingestion or entanglement every year. As plastic production is expected to double in the next decade, the problem of plastic pollution in our oceans will only worsen unless we take decisive action to reduce, reuse, and recycle plastic waste.

Plastic production and consumption are predicted to double by 2034

Plastic pollution is a pressing issue that affects all ecosystems, including land, freshwater, and marine environments. It is a significant contributor to biodiversity loss, ecosystem degradation, and climate change. The impact of plastic pollution is felt disproportionately by islands, developing countries, indigenous peoples, local communities, women, and children, as many nations lack the capacity and infrastructure to properly manage plastic waste.

The world currently produces over 460 million metric tons of plastic annually, according to the United Nations Environment Programme. Plastic is used in almost all consumer and industrial activities, from construction and electronics to agriculture and vehicles. It is estimated that around 12.7 million tonnes of plastic waste enter our oceans each year, with 5000 items of marine plastic pollution found per mile of beach in the UK. This plastic pollution comes from various sources, including urban and stormwater runoff, littering, industrial activities, tyre abrasion, construction, and agriculture.

The problem of plastic pollution is expected to worsen, with predictions that plastic production and consumption will double by 2034. This means that the amount of plastic entering our oceans and polluting our ecosystems will significantly increase unless drastic action is taken. The impact of plastic pollution on marine life is devastating, with more than 1 million seabirds and 100,000 marine animals dying from plastic pollution annually. Additionally, 100% of baby sea turtles have plastic in their stomachs, and microplastics have been found in human blood and placentas, as well as in food and drinks.

To address this growing crisis, a global plastics treaty is needed to reduce plastic production, phase out harmful products and chemicals, and implement strong national plans and reporting mechanisms. Individual actions, such as reducing, reusing, and recycling plastic items, as well as participating in cleanup efforts, are also crucial in combating plastic pollution. Without collective action from individuals, communities, and nations, the damage to our oceans and ecosystems will have irreversible consequences.

88% of the sea's surface is polluted by plastic waste

Plastic pollution is a pressing issue that affects all ecosystems, including marine environments. It is estimated that 88% of the sea's surface is polluted by plastic waste, with billions of pounds of plastic found in swirling convergences that make up about 40% of the world's ocean surfaces. This plastic pollution comes from a variety of sources, including single-use products such as bottles, caps, straws, cups, bags, and packaging, as well as microplastics from sources like synthetic textiles, tyres, and personal care products.

The impact of plastic pollution on marine life is devastating. It is estimated that more than 1 million seabirds and 100,000 marine animals die from plastic pollution each year, and 100% of baby sea turtles have plastic in their stomachs. Plastic debris can be ingested by marine animals, leading to internal injuries and death, or entanglement, causing injury and mortality. Additionally, toxic contaminants can accumulate on the surface of plastics, which are then transferred to humans through seafood consumption.

The problem of plastic pollution is not limited to the oceans; it also affects freshwater and land ecosystems. It contributes to climate change and is a major driver of biodiversity loss and ecosystem degradation. The economic costs of plastic in the ocean are estimated to be between $6-19 billion USD annually, impacting tourism, fisheries, and clean-up efforts. Furthermore, the global trade of plastic products and waste disproportionately affects islands, developing countries, indigenous peoples, local communities, women, and children, as they often lack the capacity and infrastructure to properly manage plastic waste.

To address this issue, it is crucial to reduce plastic use, improve waste management systems, and promote recycling. Individual actions, such as reducing disposable and single-use plastic items, reusing and recycling, and participating in cleanup efforts, are important steps towards mitigating plastic pollution. Additionally, supporting legislation that aims to reduce plastic use, improve recycling facilities, and enhance waste management is essential. The recent adoption of the resolution "End plastic pollution: towards an International legally binding instrument" by 175 countries is a positive step towards addressing this global issue.

The Great Pacific Garbage Patch is twice the size of Texas

The Great Pacific Garbage Patch is a massive accumulation of plastic waste in the Pacific Ocean, located between California and Hawaii. It is a stark reminder of the severity of marine plastic pollution, which affects all land, freshwater, and marine ecosystems. The patch, which is approximately twice the size of Texas, or 620,000 square miles, serves as a stark reminder of the urgent need to address plastic pollution.

The Great Pacific Garbage Patch is not a solid mass of trash but rather a collection of plastic debris, mostly microplastics, swirling within a giant gyre. This gyre, the North Pacific Subtropical Gyre, is one of five major ocean gyres that act as accumulation zones for plastic waste. The patch is estimated to contain 1.8 trillion pieces of plastic, weighing around 80,000 tonnes. This includes macroplastics, such as abandoned fishing nets, and microplastics, which can come from larger plastics breaking down or be produced as small plastics like microbeads found in personal care products.

The impact of the Great Pacific Garbage Patch extends beyond just the physical presence of plastic waste. It has become a permanent home to coastal species, with thriving communities of organisms, including tiny crabs and anemones, living and reproducing on the plastic debris. This has led to the creation of new floating ecosystems, as species that would typically survive in coastal habitats now find themselves thousands of miles from their original homes. The introduction of these new species into remote areas of the ocean may have unknown consequences, including potential competition for space, food, and predation.

The Great Pacific Garbage Patch is a sobering example of the long-term impact of plastic pollution. Unlike organic material, plastic debris can float in the oceans for extended periods, providing a long-lasting platform for creatures to survive and reproduce. This highlights the importance of addressing plastic pollution through a combination of reduced plastic use, improved waste management, and global cooperation to curb the flow of plastic into our oceans.

In conclusion, the Great Pacific Garbage Patch, twice the size of Texas, is a pressing environmental concern. Its existence underscores the urgent need to address plastic pollution through collective efforts and global awareness. By reducing, reusing, and recycling plastic items, we can work towards mitigating the impact of plastic waste on our oceans and the ecosystems they support.

100% of baby sea turtles have plastic in their stomachs

An estimated 20 million metric tons of plastic waste ends up in the environment every year, polluting all ecosystems. This number is expected to increase significantly by 2040. Plastic is a synthetic, organic polymer made from fossil fuels, and it is used in almost all consumer and industrial activities. As a result, plastic pollution has become one of the most pressing threats to marine wildlife, with an estimated 75 to 199 million tons of plastic waste currently circulating in our oceans.

One of the most affected marine species is sea turtles, with 100% of baby sea turtles having plastic in their stomachs. A study published in Frontiers in Marine Science examined the contents of the stomachs, intestines, cloaca, and bladder of stranded or bycaught turtles from the Indian Ocean off Western Australia and the Pacific Ocean off Eastern Australia. The researchers found that the amount of plastic ingested varied by ocean and species, with green turtles in the Indian Ocean containing up to 343 pieces of plastic and those in the Pacific Ocean containing up to 144 pieces.

The ingestion of plastic by sea turtles can have devastating consequences for their health and survival. Turtles may mistake plastic debris for food, leading to a false sensation of fullness and subsequent starvation. Additionally, the ingestion of plastic can cause internal injuries, such as punctures or blockages in the gut. Research by the University of the Sunshine Coast found that even a single piece of plastic can kill a turtle, with a 22% chance of mortality associated with consuming just one piece.

The presence of plastic in the stomachs of baby sea turtles highlights the urgent need to address plastic pollution in our oceans. While it is challenging to determine the exact amount of plastic in the ocean, it is clear that our actions have severe consequences for marine life. By reducing plastic use, reusing and recycling items, and participating in cleanup efforts, we can work towards mitigating the impact of plastic pollution on vulnerable species like sea turtles.

Mismanaged waste is much higher in low-to-middle-income countries

Plastic pollution is a pressing issue that affects all ecosystems, including marine life. It is estimated that between 4.8 and 12.7 million tonnes of plastic are dumped into our oceans annually, with around 8 million pieces of plastic entering the oceans each day. This plastic pollution comes from a variety of sources, including single-use products such as bottles, caps, bags, cups, and straws, as well as paint shed from shipping, discarded fishing gear, tyre abrasion, construction, and agriculture.

While plastic pollution is a global issue, the mismanagement of plastic waste tends to be much higher in low-to-middle-income countries. This is due to a lack of capacity and infrastructure to properly manage plastic waste. Many developing countries lack the necessary infrastructure to handle plastic waste safely and environmentally soundly. As a result, they often become dumping grounds for plastic waste from wealthier nations. For example, Turkey, which accounts for roughly 2.7% of global mismanaged plastic waste, received approximately 700,000 metric tons of plastic waste exports from the European Union in 2020.

The top 10 countries with the largest shares of global mismanaged plastic waste in 2019 were primarily low-to-middle-income countries, including India (21%) and China (20%). China, despite being one of the largest producers of plastic waste, had one of the lowest per capita productions of plastic waste in the world in 2016, at 15.6 kilograms per person per year. This indicates that the issue is not solely about production but also about the capacity to manage and dispose of plastic waste properly.

Domestic policies and foreign investments in waste management infrastructure are crucial to addressing this issue. Studies have shown that Asian countries contribute significantly to plastic emissions in the ocean, with a 2017 study estimating that Asian nations were responsible for 86% of plastic emissions in the ocean. This highlights the importance of improving waste management strategies and infrastructure in low-to-middle-income countries to reduce plastic pollution.

The impact of plastic pollution is far-reaching and long-lasting. Plastic can break down into microplastics, which can absorb harmful pollutants and release them into the ocean. These microplastics have been found in human blood, placentas, food, and drinks, posing risks to human health. Additionally, plastic pollution can lead to biodiversity loss, ecosystem degradation, and contribute to climate change. Therefore, addressing the mismanagement of plastic waste in low-to-middle-income countries is essential to mitigating the environmental and health risks associated with plastic pollution.
