America's Plastic Ocean: A Troubling Impact

Plastic pollution in the ocean is a pressing issue that poses a threat to marine life and ecosystems. While it is challenging to determine the exact amount of plastic in the ocean, it is estimated that around 8 million metric tons of plastic entered the ocean in 2010, and the problem has only grown since. America is a significant contributor to plastic pollution, with an estimated 37,825,550 metric tons of plastic waste generated in the country. Additionally, studies indicate that America has the highest per capita plastic waste, with 105kg of plastic thrown away per person per year. The impact of plastic pollution on marine life is devastating, with entanglement, ingestion, and the release of harmful pollutants being among the most detrimental effects.

America's plastic waste per capita

The United States generates the most plastic waste of any country in the world, with 42 million metric tons, or 286 pounds per person, produced in 2016 alone. This equates to 105kg of plastic thrown away per person per year. However, the US contributes just 0.2% of the world's ocean plastic, as most of the country is landlocked, and the plastic ends up in landfills.

The US is the third-largest contributor to plastic pollution in coastal environments, with 1.5 million tons ending up in coastal areas that directly feed into the ocean. This is a fivefold increase since 2010. Less than 10% of plastic waste in the US was collected for recycling in 2016, and as much as half of this plastic was shipped overseas to countries with ineffective waste management systems.

The US's high per-capita plastic waste generation is partly due to its large packaging market, which accounts for just over 40% of total plastic usage. In 2014, 100.7 billion plastic beverage bottles were sold in the US, or 315 bottles per person, with 57% of these being plastic water bottles. Single-use plastic bags are also a significant contributor, with several US states, such as California and New York, introducing bans in recent years.

While the US has taken steps to reduce its plastic waste, the problem is a global one, with developing countries responsible for the highest quantities of ocean plastic due to poor waste management. To end plastic pollution, adequate waste management is crucial, and richer countries can contribute through foreign investments in waste management infrastructure in developing nations.

The impact of plastic on marine life

Plastic pollution is a pressing issue that poses a grave threat to marine life. The impact of plastic on marine life is extensive and detrimental, causing fatalities and injuries among various species. The presence of plastic in the ocean is primarily due to land runoff, littering, and the disposal of plastic products such as plastic bags, straws, bottles, and fishing gear.

One of the most significant consequences of plastic pollution in the ocean is the ingestion of plastic by marine animals. Seabirds, sea turtles, and whales are among the most affected by this issue. Seabirds, in particular, mistake floating plastic debris for food, leading to detrimental effects on their growth and survival. Studies have found high amounts of plastic in the stomachs of chicks, indicating that adults inadvertently feed plastic to their offspring. Sea turtles also struggle to differentiate between plastic and their prey, often consuming plastic bags, balloons, and food wrappers. In a Mediterranean study, it was found that almost half of the examined loggerhead sea turtles had ingested plastic, with one turtle containing an alarming 67 pieces.

Whales, one of the largest marine creatures, are not exempt from the dangers of plastic pollution. They accidentally gulp down balloons and other plastic items while feeding, leading to fatal blockages in their digestive tracts. This can cause them to become too weak to surface or strand themselves, ultimately resulting in death. Additionally, smaller pieces of plastic, known as microplastics, can be ingested by marine life. These microplastics can absorb harmful pollutants and later release them into the ocean, contaminating the water and affecting the health of marine organisms.

Plastic pollution also poses a threat to marine life through entanglement. Sea turtles, whales, and other marine species can become entangled in discarded fishing nets, plastic bags, and other plastic debris. This entanglement can lead to injuries, loss of limbs, and even death. The impact of plastic pollution on marine life is not limited to fatalities and physical harm. It also disrupts the natural ecosystems that are fundamental for conservation and human well-being. For example, the build-up of plastic litter can negatively impact coastal protection services provided by healthy mangroves and freshwater provision by wetlands.

To address the impact of plastic on marine life, it is crucial to reduce plastic use, improve waste management practices, and support the development of fundamental waste collection and management systems. By taking action and making conscious choices, we can work towards mitigating the detrimental effects of plastic pollution on marine ecosystems and the diverse range of species that inhabit them.

Plastic production and consumption

The US plastic industry is massive, with plastic production exceeding 107 million metric tons annually. This makes the US one of the largest plastic producers globally, accounting for nearly 20% of the world's plastic production. Much of this plastic is intended for single-use applications, such as packaging, which has a short lifespan before becoming waste. The country's high consumption rates further exacerbate the issue, with Americans discarding an estimated 30 million tons of plastic waste each year. This waste often ends up in landfills, but a significant portion also makes its way into the environment, including oceans, due to improper disposal and inadequate waste management infrastructure.

Plastic consumption in the US spans various sectors, including packaging, consumer goods, construction, and automotive. Plastic packaging, in particular, is ubiquitous, accounting for nearly half of all plastic waste generated in the country. The convenience and versatility of plastic have led to its widespread use in products ranging from food and beverage containers to personal care items and household goods. However, the linear model of plastic production and consumption, where resources are extracted, products are manufactured, used, and then discarded, has resulted in an unprecedented plastic waste crisis.

The impact of plastic consumption is felt most acutely in the oceans. While riverine input is the primary source of plastic waste in the oceans, with an estimated 8 million metric tons entering annually, the US contributes significantly to this through its waste generation and export of plastic waste to countries with inadequate waste management systems. Plastic waste, due to its durability and resistance to degradation, persists in the marine environment, breaking down into microplastics over time. These microplastics can be ingested by marine organisms, leading to bioaccumulation and potential toxic effects on marine ecosystems.

Mismanagement of plastic waste

Plastic pollution is a critical issue that poses a severe threat to the health of our oceans and the environment as a whole. The mismanagement of plastic waste is a significant contributor to this crisis. Mismanagement refers to the improper handling, treatment, and disposal of plastic materials, leading to their unintended release into natural environments. This mismanagement takes various forms and has far-reaching consequences, with plastic's durability and resistance to decomposition exacerbating its impact.

One aspect of mismanagement is the lack of proper collection and disposal systems. Insufficient infrastructure, limited resources, and inadequate legislation contribute to this issue. Many countries, particularly those with lower to middle incomes, lack the necessary infrastructure and technical skills for effective waste management. This results in open burning, unwise dumping, and poorly managed disposal sites, which can lead to plastic pollution in the ocean.

Inadequate waste management practices also extend to recycling and recovery operations. Recycling infrastructure is often underdeveloped, and a lack of awareness about rules and regulations further exacerbates the problem. As a result, a significant portion of plastic waste ends up in landfills, where it can still pose environmental risks. Improper disposal techniques, such as dumping plastic waste on land or at sea, contribute to soil infertility, groundwater contamination, and disturbances to marine life.

The probability of mismanaged plastic waste entering the ocean varies globally, influenced by factors such as proximity to coastlines, terrain, precipitation patterns, and the presence of river systems. Middle-income countries, particularly in Asia, are major contributors to ocean plastic pollution due to these factors. However, it is important to note that the complex movement of plastic waste across borders, as seen with plastic waste exports and imports, makes it challenging to determine the exact sources of ocean plastic.

To address the mismanagement of plastic waste, a multi-faceted approach is necessary. This includes improving waste collection and management practices, particularly in rapidly growing economies with increasing disposable plastic usage. Supporting the development of fundamental waste management infrastructure and promoting recycling and responsible waste disposal practices are crucial steps. Additionally, reducing plastic production and usage, as well as holding plastic producers accountable for the harmful waste they generate, are essential components of a comprehensive solution.

The future of plastics in the ocean

The impact of plastic pollution on marine life and ecosystems is devastating. Marine animals die from ingesting or becoming entangled in plastic debris, and microplastics are now part of the food chain, found in drinking water, salt, beer, and soil. Plastic pollution is also detrimental to human health, as the materials are carcinogenic and can affect the endocrine system.

To combat this issue, individuals can reduce their plastic use, reuse and recycle plastic items, and participate in cleanup efforts. However, the root of the problem lies in the production and management of plastic. Half of all plastics have been manufactured in the last 20 years, and the plastic industry's control over waste disposal is a growing concern. California has introduced a law holding producers and vendors of plastic packaging responsible for waste, and similar policies are being advocated for to keep oceans trash-free.

The implementation of waste collection and recycling infrastructure is crucial to addressing ocean plastic pollution. This includes supporting developing countries with rapid economic growth and high disposable plastic usage to manage their plastic waste effectively. Additionally, addressing the issue of ocean plastic pollution has the added benefits of improving public health, reducing respiratory illnesses, and preventing food chain contamination.
