Sadly, most people have no idea how severe plastic pollution in the ocean actually is. Each year at least 8-14 million tons of plastic finds its way into the world’s oceans, making up roughly 80% of all marine debris, devastating marine life and the ecosystems that support them.

Welcome to Eco Vitality. Here we will review one of the most pressing environmental issues of our time: plastic pollution in our oceans. In this post, we’ll look into the alarming scope of this crisis, exploring its widespread impacts on marine life, ecosystems, and even human health.

Through this exploration, we aim to bring awareness to the urgency of addressing plastic pollution and inspire action towards a cleaner, healthier future for our oceans and, in turn, our planet as a whole.

The Scope of the Problem

Plastic pollution is a global environmental crisis that is characterized by the buildup of plastic waste in marine environments. From plastic bags to bottles, straws to packaging materials, our oceans have essentially become a massive trash receptacle for discarded plastics. Over time, these items break down into smaller fragments, exacerbating the problem and posing serious threats to marine life.

The scale of plastic pollution in our oceans is hard to comprehend. According to a study from 2014, it was estimated that more than 5 trillion plastic pieces weighing over 250,000 tons were afloat in the sea; the numbers have likely only increased since then. By 2050, it’s projected that there will be more plastic than fish in the ocean by weight if current trends continue. These statistics paint a grim picture of the immensity of the challenge we face.

Plastic pollution poses a grave threat to marine ecosystems and the creatures that inhabit them. Marine animals, from seabirds to whales, often mistake plastic debris for food, leading to ingestion and entanglement. This can cause internal injuries, starvation, and even death. Additionally, plastics can leach harmful chemicals into the water, further compromising the health of marine organisms and ecosystems. 

The consequences of plastic pollution echo through the marine food web, ultimately impacting human populations that depend on the ocean for sustenance and livelihood.

To put it simply, this is a really big issue—one that requires urgent attention seeing that oceans cover about 71% of the Earth’s surface.

Sources and Types of Ocean Plastic

Plastic waste in the oceans originates from a variety of sources, including:

   1. Land-based sources: The majority of plastic pollution in the oceans comes from land-based activities, such as short-sighted waste management systems, careless littering, and runoff from urban areas. Rivers serve as major conduits for transporting plastic waste from inland areas to the sea.

   2. Marine activities: Shipping, fishing, and aquaculture activities also contribute to ocean plastic pollution. Lost or discarded fishing gear, known as ghost gear, can persist in the ocean for years, entangling marine life and damaging habitats. An estimated 640,000 metric tons of ghost gear are left in our oceans each year.

   3. Microplastics: Microplastics, tiny plastic particles less than 5 millimeters in size, are another significant source of ocean plastic pollution. These particles typically come from the breakdown of larger plastic items but also exist in “micro” form in many consumer goods.

The types of plastic found in the ocean vary widely, including:

   1. Single-use plastics: Items such as plastic bags, bottles, straws, and food packaging are among the most commonly found plastics in the ocean. These items are designed for short-term use but often persist in the environment for hundreds of years. Research has shown that upwards of 80% of plastic pollution in oceans is from single-use plastics. 

   2. Microplastics: Microplastics come in various forms, including microbeads used in personal care products, microfibers shed from synthetic clothing, and fragments resulting from the breakdown of larger plastic items.

   3. Abandoned fishing gear: Lost or discarded fishing nets, lines, and traps contribute significantly to ocean plastic pollution. These items can continue to trap and kill marine life long after they are abandoned.

Repercussions of Plastic Pollution

Environmental Consequences

Plastic pollution poses a myriad of environmental consequences, which includes but is not limited to:

   1. Harm to Marine Life: Marine animals often mistake plastic debris for food, leading to consumption, and often end up entangled in nets and various forms of packaging like drinking can rings and plastic bags. This can result in internal and external injuries, starvation, and premature death. Additionally, plastic debris can smother and damage sensitive habitats such as coral reefs and seagrass beds which play fundamental roles in many marine ecosystems.

   2. Disruption of Ecosystems: Plastic pollution can disrupt marine ecosystems by altering habitats, displacing native species, and introducing invasive species. This can have cascading effects throughout the food web, affecting biodiversity and ecosystem functioning.

   3. Contamination of Water and Soil: Plastics can leach harmful chemicals, like polychlorinated biphenyls (PCBs), into the water—poisoning marine environments and posing toxic risks to aquatic organisms. Additionally, plastic pollution on beaches and coastlines can degrade soil quality and harm land-based wildlife.

Economic Consequences:

The economic impacts of plastic pollution are substantial and far-reaching, including:

   1. Losses to Fisheries and Tourism: Plastic pollution can harm industries such as fishing and tourism, which rely on healthy marine ecosystems. Entanglement in fishing gear can damage fishing equipment and significantly reduce catch yields due to declining marine populations, while plastic-littered beaches can deter tourists and damage coastal economies.

   2. Cleanup Costs: The cost of cleaning up plastic pollution from beaches, coastlines, and waterways can be significant, placing significant burdens on local governments and taxpayers—like you. The economic costs of plastic pollution also extend beyond cleanup efforts to include lost revenue from the abovementioned reduced tourism and losses in the fishing industry.

Human Health Consequences

Plastic pollution also poses severe risks to human health through:

   1. Contaminated Seafood: Plastics can accumulate toxic chemicals from the environment and also release them themselves as they break down. These chemicals enter the food chain through seafood consumption. This can and often does expose humans to harmful chemicals such as bisphenol A (BPA), phthalates, and polychlorinated biphenyls (PCBs).

   2. Airborne Microplastics: Recent studies have found microplastics in the air we breathe, raising concerns about potential health effects from inhalation. While the health impacts of airborne microplastics are still being studied, preliminary research suggests they could pose serious risks to respiratory health. 

Efforts to Combat Plastic Pollution

Policy Initiatives

Governments and international organizations have implemented policy initiatives in attempts to address plastic pollution. These efforts have taken the form of bans and restrictions on single-use plastics such as plastic bags, straws, and utensils, aiming to reduce the consumption and production of disposable plastics and encourage the use of reusable alternatives. 

Additionally, Extended Producer Responsibility (EPR) programs have been introduced to shift the responsibility for managing plastic waste from taxpayers to producers, incentivizing manufacturers to design more environmentally friendly products. International agreements such as the Basel Convention and the Montreal Protocol have also begun to include provisions for regulating the transboundary movement and disposal of hazardous wastes, including plastic waste.

Innovation and Technology

Innovative solutions and technologies are being developed to mitigate plastic pollution from various angles. Biodegradable plastics, designed to break down more quickly in the environment, offer a potential solution to reducing the persistence of plastic waste.

Ocean cleanup initiatives led by organizations and startups are deploying technologies like floating barriers, skimmers, and autonomous drones to remove plastic pollution from the oceans. While these initiatives show promise, their effectiveness and scalability are still being evaluated. Circular economy approaches also give hope for minimizing waste and maximizing resource efficiency by designing products for reuse, recycling, and composting, thereby reducing the total amount of plastic entering the oceans.
