Ocean Pollution: Tons Of Devastation

Plastic pollution in the ocean is a pressing environmental issue that requires global cooperation. It is estimated that between one and two million tons of plastic enter our oceans annually, threatening marine life, ecosystems, food safety, human health, and contributing to climate change. While the majority of plastic pollution in the ocean is caused by littering, a significant amount also comes from improper manufacturing processes and industrial fishing. With plastic production projected to increase, addressing plastic waste management, especially in middle to low-income countries, is critical to tackling this problem.

Plastic pollution: the leading cause of marine species extinction

Plastic pollution is one of the most pressing environmental issues that requires worldwide cooperation. It is estimated that between 1 and 2 million tons of plastic enter the oceans annually, with around 8 to 10 million metric tons of plastic ending up in the ocean each year. Plastic waste makes up 80% of all marine pollution. The majority of plastic pollution in the ocean is caused by littering, with items such as food wrappings, plastic bags, razors, and bottles ending up in waterways and eventually in the ocean. In addition, about 20% of ocean plastic pollution comes from industrial fishing and improper manufacturing processes.

The consequences of plastic pollution affect the entire planet and its inhabitants. It threatens ocean health, marine species, food safety and quality, human health, coastal tourism, and contributes to climate change. Marine wildlife suffers direct and damaging effects from plastic pollution. From fish to turtles, seals, crustaceans, microorganisms, and many other forms of life, the damage caused by plastic pollution to marine animals is increasingly visible. One of the biggest dangers of plastic pollution is its durability. Once plastic enters the ocean, it can persist for long periods, with estimates of several hundred years for it to degrade. Even then, it may not fully degrade but instead become microplastics, which can be ingested by marine animals and enter the food chain.

Plastic pollution in the ocean has led to the entanglement and ingestion of plastic by marine animals, causing injury and death. Large items of plastic can entangle marine mammals and fish, leading to starvation, injury, and increased vulnerability to predators. Discarded fishing nets can also smother and break coral reefs, hindering their healthy growth. Microplastics, on the other hand, can be mistaken for food by seabirds and other marine species, leading to suffocation, starvation, and toxic contamination. It is estimated that marine plastics contribute to the death of more than 100,000 marine mammals every year, with hundreds of thousands of seabirds ingesting plastic annually.

The presence of plastic in the ocean also affects marine ecosystems and biodiversity. Floating plastic items can transport invasive species, threatening the marine food web. Microplastics have been found in drinking water, salt, beer, soil, and the bodies of marine organisms, including fish consumed by humans. These microplastics can adsorb toxins, transferring them to the fatty tissues of the organisms that ingest them. As a result, plastic materials have been linked to various health issues, including developmental, neurological, reproductive, and immune disorders.

Overall, plastic pollution is a significant contributor to the extinction of marine species. Its persistence in the ocean, coupled with improper waste management and littering, has led to the entanglement, ingestion, and toxicity of marine life. The far-reaching consequences of plastic pollution on ocean health, ecosystems, and biodiversity highlight the urgent need for global cooperation to address this environmental crisis.

Plastic waste: the mismanagement of recycling and waste disposal

Plastic waste is a critical global issue that requires immediate attention and action. The mismanagement of plastic waste and recycling processes has led to widespread pollution, damaging the environment, human health, and economies. The consequences of plastic pollution are far-reaching, threatening ocean health, marine life, food safety, ecosystems, and contributing to climate change.

Plastic, a durable material, takes hundreds of years to degrade, and even then, it may only break down into microplastics, which remain in the environment. The presence of plastic in our oceans is a significant concern, with an estimated 1 to 2 million tons of plastic entering the oceans each year. This plastic pollution comes from various sources, including littering, improper waste management, and industrial activities.

The majority of plastic pollution in the ocean is caused by littering and improper disposal. Disposable plastic items such as food wrappings, plastic bags, razors, and bottles are often not disposed of properly, ending up in waterways and, eventually, the ocean. While high-income countries have effective waste management systems that minimize the impact of plastic pollution, lower-income countries often struggle with inadequate waste management infrastructure, contributing to the issue.

The mismanagement of plastic waste includes a lack of recycling, incineration, or proper landfill disposal. This mismanagement leads to plastic leaking into the environment and, ultimately, the ocean. It is estimated that only 9% of plastic waste is recycled globally, with half going straight to landfills and another fifth being mismanaged. The probability of mismanaged plastic entering the ocean varies depending on factors such as proximity to coastlines, river systems, terrain, and precipitation patterns.

To address the issue of plastic waste mismanagement and reduce ocean pollution, it is crucial to improve waste management practices, especially in lower- and middle-income countries. This includes investing in infrastructure, developing adequate dumping techniques, and implementing effective legislation. By preventing plastic waste from entering rivers and seas, we can mitigate the damaging effects of plastic pollution on marine life, ecosystems, and human health, working towards a more sustainable future.

Microplastics: the tiny particles that enter the food chain

Plastic waste makes up 80% of all marine pollution. While estimates vary, it is thought that between 1 and 2 million tons of plastic enter the oceans annually. Some earlier estimates placed this figure at 8 million tons.

Plastic is one of the most enduring materials ever created by humans. It can take hundreds of years to degrade, and even then, it may not fully degrade but instead become what we call microplastics. These are tiny particles of plastic that can be eaten by marine animals, entering their bodies and tissues and threatening their health. Even if plastic waste is correctly recycled, incinerated, or kept in sealed landfills, it can still enter the oceans via landfills. Here, plastic can be spread by wind into rivers and, ultimately, the sea.

Microplastics have been found in the land, sea, and air, across the food chain, and throughout the human body. They have been detected in blood, lungs, livers, lower limb joints, and even brains. A 2022 study found microplastics in blue mussels off the Australian coast, and microplastics have also been found in honey, tea, sugar, fruit, and vegetables. They are also making their way onto farmland through sewage sludge used as fertilizer. While the full extent of the environmental and health impacts of microplastics is not yet known, studies indicate that they can increase the likelihood of heart attack, stroke, or death.

Scientists have declared that the best solution to the problem of microplastics in the ocean is to prevent plastic waste from entering rivers and seas in the first place. One innovative method for removing microplastics from water involves using vegetable oil, iron oxide, and magnets, and has been found to be 87% effective.

Marine wildlife: the direct impact of plastic pollution

Marine wildlife is facing a direct and deadly threat from plastic pollution. Plastic waste makes up 80% of all marine pollution, with an estimated one to two million tons of plastic entering our oceans each year. Plastic's durability is one of its greatest assets, but this means that once it enters the ocean, it will remain there for a long time, with plastic persisting in the ocean for decades. Marine animals are bearing the consequences of our plastic waste.

Plastic pollution in the ocean affects all kinds of marine life, from fish to turtles, seals, crustaceans, microorganisms, and many other forms of life. One of the most common and devastating impacts is entanglement. Large items of plastic can capture marine mammals and fish, preventing them from escaping and leading to starvation, injury, and increased vulnerability to predators. This is a particular threat to endangered species, such as the Hawaiian monk seal, for which fishing gear entanglement is the second leading cause of death after deliberate killing. Endangered Pacific loggerhead sea turtles are also among the nearly 700 species that eat and get caught in plastic litter.

Ingestion of plastic is another significant issue, with plastic debris causing suffocation, starvation, and drowning in fish, seabirds, sea turtles, and marine mammals. Seabirds and other marine species may mistake small plastic fragments floating on the water for food, leading to toxic contamination over time. Microplastics, which are invisible to the naked eye, are easily consumed by wildlife and can adsorb up to one million times more toxic chemicals than the surrounding water, transferring these toxins to the fatty tissues of the organisms that ingest them. A recent study found that 100% of mussel samples sourced from UK waters contained microplastic pieces.

The presence of plastic in the ocean also encourages the growth of pathogens. Corals that come into contact with plastic have an 89% chance of contracting diseases, compared to a 4% likelihood for corals that are not exposed to plastic. Plastic pollution is a pressing environmental issue, threatening ocean health, marine species, food safety, human health, and contributing to climate change. It is a global crisis that requires worldwide cooperation to address.

Oil in the sea: the runoff from roads, rivers and drainpipes

The ocean is one of the most important natural resources on Earth, but it is facing a growing threat from pollution. Plastic waste makes up 80% of all marine pollution, with an estimated one to two million tons of plastic entering our oceans annually. This plastic pollution has severe consequences for marine life, human health, and the environment.

While large oil spills often grab headlines, it is important to recognize that they account for only about 10% of the oil that reaches the sea due to human activity. The remaining 90% is a result of chronic low-level releases associated with petroleum extraction and consumption, with nonpoint source pollution being the biggest problem.

One significant contributor to oil pollution in the sea is runoff from roads, rivers, and drainpipes. When it rains, oil and grease deposited on roadways by motor vehicles are washed away, eventually making their way into coastal waters. This runoff can have detrimental effects on the environment, including marine life and ecosystems.

Oil runoff from roads is a significant issue, as the oil and grease can be quickly washed away by rainwater, creating slick road conditions and impacting driving experiences. Additionally, the environmental impact of this runoff is concerning, as it can contaminate nearby bodies of water and eventually reach the sea, causing a range of ecological problems.

Furthermore, rivers and streams play a crucial role in transporting oil pollution to the sea. These water bodies receive runoff from various land-based activities, delivering millions of gallons of oil to coastal waters each year. The impact is particularly noticeable in watersheds that drain heavily populated areas, where the oil and other pollutants accumulate and eventually find their way into the marine environment.

To address the issue of oil runoff from roads, rivers, and drainpipes, it is essential to implement effective pollution prevention measures. This includes proper waste management practices, such as ensuring that motor oil is disposed of responsibly and not dumped into drains or leaked onto the ground. By addressing these sources of pollution, we can significantly reduce the amount of oil that reaches the sea and mitigate its harmful effects on the marine environment and ecosystems.
