The Rising Tide of Marine Debris: Understanding and Combating Ocean Pollution

Marine debris, the unwanted remnants of human activity, has insidiously pervaded our oceans, threatening marine life and our health. This article investigates the myriad sources contributing to this silent crisis, assesses its profound repercussions, and highlights collective efforts to tackle the floating menace. Join us to uncover how global action is making a difference.

Key Takeaways

• Marine debris, primarily plastic waste, poses a severe environmental crisis affecting marine wildlife and ecosystems. It's estimated that 400 million metric tons of plastic are produced annually. With less than 0.5% of this production ending up in the ocean, this still translates to over 1 million metric tons of marine debris.

• International cooperation is key to combating marine pollution, with efforts such as the anticipated global plastics treaty to regulate plastic life-cycle and UN resolutions to reduce marine litter, highlighting the need for comprehensive governance and accountability.

• The Dive Against Debris initiative by PADI AWARE involves divers globally in underwater cleanups and data collection to inform policies, with over 37,000 sea creatures rescued and over 2 million pieces of debris removed, showcasing the significant impact of collective conservation efforts.

The Peril of Plastic in Our Oceans

It’s hard to imagine a world without plastic. This versatile material has revolutionised industries, from healthcare to aerospace. However, our reliance on disposable plastic products has birthed a global pollution issue, with over 400 million metric tons of plastic produced annually. Less than 0.5 percent of this colossal amount ends up in our oceans, translating to over 1 million metric tons of marine debris. Alarmingly, around 90% of visible marine debris is discarded plastic, evident in massive accumulation areas like the Great Pacific Garbage Patch.

The marine environment and its inhabitants, including various marine organisms, bear the brunt of this pollution. From tiny plankton to majestic whales, marine wildlife is suffering significantly from marine debris through ingestion, entanglement, and habitat disruption. The sheer volume of plastic waste in our oceans is not just an environmental issue; it’s a crisis that’s disrupting entire ecosystems and impacting marine life.

But where does all this plastic come from, and how does it end up in our oceans? Let’s unravel this journey.

The Invention and Proliferation of Plastic

The invention of plastic was truly revolutionary, enabling the development of life-saving medical devices, facilitating space travel, and creating systems for clean drinking water. Over time, plastic found its way into nearly every aspect of our lives. From the phone you’re holding to the plastic bags you use for groceries, plastic is everywhere. The convenience and versatility of plastic, especially single-use plastics, have led to a throw-away culture. Today, plastic waste is one of the most pressing environmental challenges we face.

About 40 percent of the plastic produced every year is composed of single-use plastics, making it a significant contributor to marine pollution. The majority of these items are used once and then discarded, ending up in landfills, rivers, and eventually, our oceans. As consumers, we must acknowledge the whole life-cycle of plastic products, from their design to end-of-life, to shift towards more sustainable consumption patterns. Embracing alternatives to single-use plastic items, such as stainless steel straws, bamboo utensils, and glass containers, can significantly reduce personal contributions to marine debris.

Tracking the Journey: From Landfills to Ocean Currents

Plastic doesn’t just magically appear in our oceans. It embarks on a perilous journey from our landfills, through our rivers, and is carried by ocean currents into the marine environment. Heavy rain events can surge plastic emissions by up to tenfold as waterways carry trash into the ocean. The proximity of plastic waste to rivers and the ocean increases the likelihood of it reaching marine environments. Moreover, the debris that enters the ocean does not always stay on the surface. Nearly half of the plastic that enters the ocean sinks immediately due to low buoyancy, while the remainder can beach on coastlines or become trapped in ocean gyres.

Understanding this journey is critical to mitigating the issue. It’s not just about cleaning up the debris; it’s about stopping it from reaching the oceans in the first place. We must focus on improve solid waste management, particularly in areas close to rivers and coasts, to prevent the escape of plastic waste into the marine environment.

When we understand the journey of plastic waste, we can implement targeted strategies to intercept it along its route, reducing the amount that reaches our oceans.

The Visible and Invisible: Macro and Microplastics

When we think of marine debris, we often visualise large pieces of plastic floating on the ocean’s surface or washed up on beaches. However, there’s another side to the plastic pollution story – the invisible threat of microplastics. These are small plastic particles often less than one fifth of an inch across, originating from the breakdown of larger plastic waste or manufactured at a microscopic size as in the case of nurdles and microbeads.

Microplastics pose a significant threat to aquatic species, which often mistake these small particles for food. This ingestion leads to:

• blocked digestive tracts

• pierced organs

• altered feeding impulses

• in severe cases, death

But it’s not just marine life at risk. Microplastics have been detected in human blood, lungs, and feces, raising urgent questions about their potential effects on human health. The issue of microplastics illustrates that the plastic pollution problem is not just visible but also invisible, seeping into the very fabric of our ecosystems and bodies.

Dive Against Debris: A Global Movement

As daunting as the marine debris issue is, there’s a global movement rising to meet the challenge. Dive Against Debris, an initiative by PADI AWARE, is the largest underwater cleanup operation globally.
