The Water's Plastic Problem: An Ominous Overview

Plastic pollution is a pressing global issue. Humans produce over 380 million tons of plastic annually, with some reports indicating that up to 50% of this is for single-use purposes. It is estimated that more than 10 million tons of plastic enter our oceans each year, with plastic debris impacting marine life and ecosystems. The true extent of plastic pollution in our seas may never be known, but current estimates suggest urgent action is required. While plastic has numerous applications and benefits, its durability means it persists in the marine environment for long periods, causing significant harm to marine animals and the environment.

Mismanagement of plastic waste

Plastic waste that is not recycled, incinerated, or kept in sealed landfills is considered mismanaged. Mismanaged plastic waste becomes an environmental pollutant, affecting wildlife and ecosystems. It is vulnerable to leaking into the environment, with a fraction making its way into the ocean. The probability of mismanaged plastic waste entering the ocean varies depending on factors such as location, proximity to coastlines, terrain, and precipitation patterns.

The main causes of mismanaged plastic waste include poor municipal waste handling, inconsistent recycling policies between countries, profit-first business models, and resource-hungry industries. While tougher laws and regulations have led to improvements in plastic waste management, they have not kept pace with the increase in plastic waste generation.

To address the issue of mismanaged plastic waste, improvements in waste management systems, such as tighter waste collection and more robust legal frameworks, are necessary. Additionally, preventing plastic waste generation in the first place is crucial. This can be achieved through reducing the use of disposable and single-use plastic items, reusing and recycling them, and participating in cleanup efforts.

The consequences of mismanaged plastic waste are severe. Plastic debris in the ocean does not fully biodegrade and can persist indefinitely, breaking down into microplastics that wreak havoc on marine life. The ingestion of plastic by animals and the entanglement of wildlife in abandoned fishing nets are significant concerns. With plastic production expected to increase, the problem of mismanaged plastic waste entering the water is set to worsen unless decisive action is taken.

Plastic production and consumption

Plastic is a versatile material used in a wide variety of products, including construction, home appliances, medical instruments, and food packaging. The proliferation of plastic products has been extraordinary, with global plastic production doubling in the last two decades. In 1950, the world produced just two million tonnes of plastic, but today, the world produces over 450 million tonnes of plastic waste each year. The bulk of this ends up in landfill, is incinerated, or leaks into the environment, with only a small percentage successfully recycled.

The largest producer of plastic in the world is Asia, with China alone accounting for 32% of global production in 2022. North America ranks second in terms of plastic production, with a 17% share in 2022. However, rich countries tend to produce the most plastic waste per person, and it is these countries that are responsible for most of the ocean plastics.

The amount of plastic waste produced each year is staggering, and a significant portion of it is not properly managed. Plastic waste that is not recycled, incinerated, or disposed of in sealed landfills can become an environmental pollutant. It is estimated that between one and two million tonnes of plastic enter our oceans each year, with some estimates reaching as high as eight million tonnes. This plastic waste comes from a variety of land and ocean-based sources, including littering, intentional or improper disposal of trash, and plastic that is lost or abandoned, such as fishing gear.

The problem of plastic pollution is set to worsen, with plastic production expected to grow by 40% in the next decade. However, there is hope that this crisis can be averted through international cooperation, innovation, better product design, and the development of environmentally friendly alternatives. Bans and taxes on single-use plastics exist in over 120 countries, but more needs to be done to reduce overall plastic consumption and improve waste management and recycling.

Plastic's impact on marine life

Marine life is facing a grave threat from plastic pollution. It is estimated that more than 10 million tons of plastic enter our oceans every year, with plastic production expected to increase by 40% in the next decade. This plastic waste comes from a variety of land and ocean-based sources, including littering, industrial activities, tyre abrasion, construction, and agriculture. Once in the water, plastic debris never fully biodegrades and can have devastating consequences for marine animals.

One of the primary ways plastic impacts marine life is through ingestion. Small plastic fragments can sit on the surface of the water and be mistaken for food by seabirds, fish, sea turtles, and other marine species. This leads to issues such as internal injuries, starvation, and toxic contamination over time. In a recent study of mussels sourced from UK waters, 100% of the samples were found to contain microplastic pieces. Even apex predators like great white sharks and orcas are at risk from the cumulative impact of microplastics in the food chain and the bioaccumulation of toxic chemicals found in plastics.

Another way plastic harms marine life is through entanglement. Large items of plastic can entangle marine mammals and fish, leading to loss of limbs, injury, and increased vulnerability to predators. Sea turtles, for example, often eat plastic bags, balloons, and food wrappers, mistaking them for their prey of invertebrates like jellyfish or sponges. In a recent Mediterranean study, almost half of the examined loggerhead sea turtles had consumed some type of plastic, with one turtle ingesting 67 pieces.

The impact of plastic pollution on marine life is far-reaching and devastating. It is estimated that marine plastics contribute to the death of more than 100,000 marine mammals annually. With plastic production and pollution showing no signs of slowing, the future of marine ecosystems looks increasingly dire unless drastic action is taken to address this issue.

Plastic's durability in water

Plastic is a relatively new invention in human history, with some of the first examples dating back to the late 1800s. However, its versatility, durability, and low production cost have made it one of the most widely used materials in modern times. It is estimated that we produce over 380 million tons of plastic annually, and some reports indicate that up to 50% of that is for single-use purposes. This "disposable" lifestyle has led to a significant environmental crisis, with unprecedented amounts of plastic waste entering our oceans every day.

The durability of plastics is due to their chemical structure. All plastic materials are polymers, which consist of very long chains of molecular units, with carbon as the defining element, almost always combined with hydrogen. Other elements that may be included are nitrogen, oxygen, fluorine, and chlorine. These long molecular chains make polymers strong, durable, flexible, and pliable. This durability becomes a curse when plastic is discarded into the environment, as it does not decompose in water and can remain in the environment for generations, causing aesthetic, ecological, and health issues.

The problem of plastic waste in water is twofold: the plastic items themselves, and the microplastics they break down into. Larger plastic items can trap and kill aquatic species, while microplastics can be ingested by marine life and enter the human food chain. Microplastics can also be released into the environment through certain products like soaps, face washes, and toothpaste. While photodegradable plastics can break down into microplastics, they never fully decompose and persist in the environment.

The impact of plastic waste in water is far-reaching. It is estimated that more than 10 million tons of plastic enter the oceans each year, with a significant portion coming from mismanaged waste and the fishing industry. The plastic waste already in the oceans is also concerning, with estimates suggesting there could be up to 10,000 times more plastic particles on the seafloor than on the surface. With plastic production expected to increase in the coming years, the crisis will only worsen unless decisive action is taken to address plastic pollution.

Global efforts to reduce plastic waste

Plastic pollution is a pressing issue that threatens the health of our oceans and the planet as a whole. Global efforts to reduce plastic waste are gaining momentum, with various initiatives and legislation being implemented to address this crisis.

One notable international effort is the Global Tourism Plastics Initiative, which aims to reduce plastic pollution generated by the tourism industry. This industry is notorious for its extensive use of single-use plastic products, which are often discarded after one or a few uses, leading to a significant increase in plastic pollution during peak travel seasons. The initiative strives to ensure that businesses, governments, and stakeholders take responsibility and work towards concrete agreements to tackle this issue by 2025.

At the country level, several nations have taken decisive action to ban or restrict single-use plastics. For instance, in 2019, Guatemala implemented a ban on single-use plastics, including plastic bags, plates, cups, and straws, with a two-year transition period for the public to adopt alternatives. Similarly, Bangladesh was one of the first countries to ban plastic bags, inspiring 76 other nations to follow suit, while 32 countries have imposed taxes or other limitations on the production and sale of plastic bags.

In 2022, the UN Environmental Assembly convened in Nairobi to discuss a potential landmark environmental policy. Their goal is to create a science-based agreement, utilizing an Intergovernmental Negotiating Committee, to address all aspects of plastic pollution by 2024. This agreement aims to recognize diverse approaches, emphasize the issue's importance, and advocate for a legal framework to combat plastic pollution.

Additionally, the Break Free From Plastic Pollution Act in the United States is a comprehensive federal bill introduced in 2021 to tackle the plastic pollution crisis. This act aims to address plastic pollution by reducing plastic production, enhancing waste management, and holding plastic producers accountable for the waste generated by their products and packaging.

The fight against plastic pollution is also gaining support from businesses and the public. Major companies are collaborating to address this issue, and organizations like the World Wildlife Fund (WWF) are leading the charge to reduce, redesign, and reuse plastic materials.

These global efforts to reduce plastic waste demonstrate a growing awareness and commitment to mitigating the harmful impacts of plastic pollution on our oceans and the environment.
