The Ocean's Plastic Problem: Seastewards' Call To Action

Plastic waste in the ocean is a pressing global issue that poses a threat to marine life, ecosystems, and human health. It is estimated that billions of pounds of plastic are present in the oceans, with around 80% of this waste originating on land due to poor waste management. This waste includes items such as plastic bags, bottles, containers, and straws, which, once in the water, never fully biodegrade and can release toxic contaminants. The presence of plastic in the ocean has led to the deaths of thousands of marine animals, including seabirds, sea turtles, and seals, who ingest or become entangled in plastic litter. With the amount of plastic in the ocean doubling every six years, it is predicted that by 2050, plastic will outweigh fish in the sea unless drastic action is taken.

Marine life endangered by plastic

Marine life is facing a grave threat from plastic pollution in the oceans. It is estimated that marine plastics contribute to the death of more than 100,000 marine mammals every year. The problem is twofold: ingestion (eating) and entanglement in plastic debris.

Marine species often mistake plastic for food. Small but visible plastic fragments can sit on the water surface and be mistaken for prey by seabirds and other marine species. Even species that do not rely on sight to identify prey are not safe. Toothed whales and many dolphin species use echolocation to find their prey, but some scientists believe that unnatural objects such as plastic waste confuse this sonar, leading them to mistakenly ingest plastic. This ingested plastic can cause inflammation of abdominal tissues, as well as suffocation and starvation. It can also lead to toxic contamination as microplastics can absorb toxins, which then transfer to the fatty tissues of the organisms that ingest them.

Large marine mammals are highly vulnerable to plastic entanglement, particularly from abandoned fishing gear. An estimated 640,000 tonnes of the 8 million tonnes of plastic that enters the oceans annually is abandoned fishing equipment. This includes plastic fishing ropes, nets, and pots that can trap and entangle a variety of marine life, from large whales to smaller creatures.

The impact of plastic pollution on marine life is widespread and devastating. It is estimated that 800 species worldwide are affected by marine debris, with plastic comprising up to 80% of this litter. From the tiniest seahorses in coral reefs to majestic whales, no marine creature is immune to this crisis. According to the United Nations, 81 out of 123 marine mammal species have ingested or become entangled in plastic, and all seven sea turtle species are affected. Endangered wildlife, such as Hawaiian monk seals and Pacific loggerhead sea turtles, are among nearly 700 species that consume and get entangled in plastic litter.

The issue of plastic pollution in the oceans is a pressing one. With an estimated 15-51 trillion pieces of plastic currently in the world's oceans, the future looks bleak for marine life unless drastic action is taken. While global awareness about plastic pollution has grown, it is imperative that we continue to address this urgent problem to protect the rich diversity of marine life from the toxic threat of plastics.

Plastic waste sources

Plastic waste in the ocean is a pressing global crisis. It is estimated that there are 358 trillion microplastic particles floating on the surface of the oceans, with countless more found at the bottom of the seabed. Marine life, such as seabirds, sea turtles, seals, and other marine mammals, is being killed due to the ingestion of plastic or entanglement.

The most common sources of plastic waste are everyday items, such as food and beverage packaging. Food wrappers, chocolate bar wrappers, snack bags, fast-food containers, and beverage bottles are some of the most prevalent forms of plastic pollution. These single-use plastics are particularly hazardous because many cannot be recycled or reused due to technological limitations and the lack of recovery markets. Bottle caps are also a significant contributor to ocean plastic pollution, as marine life often mistakes them for food.

Takeout containers contribute substantially to plastic waste. While it can be challenging to address this issue, individuals can take action by using their containers for takeout or supporting businesses that employ sustainable practices and reusable packaging.

Poor waste management is another critical factor in the plastic pollution of oceans. Improper disposal of single-use plastics and inadequate management of waste lead to plastic ending up in rivers and the sea. As a result, plastic debris, which does not fully biodegrade, wreaks havoc on marine ecosystems.

Plastic waste management

The issue of plastic waste in the oceans is a pressing one, with an estimated 70% of plastic waste remaining uncollected and entering our oceans, landfills, or being burned in 2023. This statistic highlights the urgent need for effective plastic waste management strategies.

One key aspect of plastic waste management is the implementation of policies and regulations that promote extended producer responsibility (EPR). This concept shifts the burden of plastic waste management from consumers to producers, encouraging manufacturers to consider the entire life cycle of their plastic products and take responsibility for their disposal or recycling. This can be facilitated through deposit-return systems (DRS), where consumers return used products or packaging to the producer, who then manages the recycling or proper disposal.

Another important strategy is the development of national action plans that are tailored to each country's unique circumstances. A meta-analysis of 192 countries identified six distinct plastic waste management and recycling maturity categories, demonstrating that there is no one-size-fits-all solution. By understanding the specific challenges and resources available, countries can design effective action plans that address their particular needs and priorities.

Additionally, plastic waste management involves improving waste management systems and recycling rates. This includes investing in infrastructure and technologies for proper collection, sorting, and recycling of plastic waste. Educating communities about the importance of recycling and proper waste disposal is also crucial, ensuring that individuals understand what can be recycled and how to prepare their recyclables for collection.

Finally, plastic waste management also entails exploring alternatives to traditional plastics and reducing plastic consumption. This can involve promoting reusable items, such as shopping bags and water bottles, and encouraging consumers to opt for more sustainable packaging options. By reducing the demand for single-use plastics and finding more environmentally friendly alternatives, we can significantly decrease the amount of plastic waste generated.

Plastic waste removal

Plastic waste in the ocean is a pressing global issue that poses a threat to marine life, ecosystems, and human health. The accumulation of plastic in our oceans and on our beaches has severe consequences, with billions of pounds of plastic making up about 40% of the world's ocean surfaces. It is estimated that there are 15-51 trillion pieces of plastic in the oceans, with 358 trillion microplastic particles floating on the surface and settling at the seabed. The impact of this waste is devastating, with thousands of marine animals, including endangered species, being killed from ingestion or entanglement.

To address this crisis, several organizations are dedicated to removing plastic waste from the oceans and preventing further pollution. One notable example is The Ocean Cleanup, a non-profit organization that has been working for over a decade to tackle plastic pollution in oceans and rivers globally. They employ advanced technologies, such as river interception systems and ocean cleanup systems, with the ambitious goal of removing 90% of floating plastic by 2040. Their efforts have already resulted in the removal of millions of kilograms of plastic waste.

Another initiative, Free the Ocean, takes a unique approach by combining trivia and sustainability. They offer an opportunity to remove a piece of plastic from the ocean by answering a daily trivia question. Additionally, they provide eco-friendly and plastic-free products, funding groups focused on plastic removal, and promoting sustainable swaps for a positive environmental impact.

In addition to these large-scale efforts, local clean-up initiatives and individual actions play a crucial role in addressing plastic waste. Participating in local clean-up activities and properly disposing of waste are simple yet effective ways to contribute to the cause. Reducing, reusing, and recycling plastic products are essential habits to adopt, as most plastic originates on land due to poor waste management.

Innovative technologies are also being explored to capture microplastics. For instance, Wasser 3.0, a German company, utilizes a non-toxic compound that clumps microplastics together for collection. Scientists at the University of Adelaide have developed carbon nanotube magnets that grab and break down microplastics into harmless substances. These advancements showcase the potential for effective microplastic removal, addressing the challenge of removing smaller plastic particles from the ocean.

Impact of plastic on human health

Plastic waste in the ocean is a pressing issue that jeopardizes aquatic life and human health. Around 80-81% of all marine litter is plastic, and it is estimated that there are currently 15-51 trillion pieces of plastic in the world's oceans, with this number expected to double every six years. Poor waste management is a significant contributor to this issue, as plastic often ends up in rivers and the sea.

The impact of plastic on human health is a growing concern and an area of ongoing research. Humans are exposed to toxic chemicals and microplastics through inhalation, ingestion, and direct skin contact. An average person may ingest approximately 5 grams of plastic every week, and microplastics have been found in seafood, tap and bottled water, and even commonly consumed beverages like beer and salt. The health effects of ingesting microplastics are still being studied, but current evidence suggests that plastic causes diseases, disabilities, and premature death at every stage of its life cycle.

The toxic chemical additives and pollutants found in plastics have been linked to endocrine disruption, which can lead to reproductive, growth, and cognitive impairments. Additionally, the production and refining of plastic involve the use of carcinogenic and highly toxic substances, which can cause cancer, leukemia, and genetic impacts like low birth weight. Vulnerable groups, including children, pregnant women, and marginalized communities, are particularly at risk of the adverse health effects of plastic exposure.

To address the health risks associated with plastic, it is crucial to adopt a lifecycle approach that considers the distinct risks at each stage, from extraction and production to consumption and waste management. Reducing the threats posed by plastic requires a global effort to curb the growth in plastic production, use, and disposal, as well as improved waste management practices to prevent plastic from ending up in our oceans.
