Plastic Oceans: Earth's Crisis And Solutions

Plastic pollution in our oceans is a pressing global crisis. It is estimated that there are 15–51 trillion pieces of plastic in the world's oceans, with billions of pounds of plastic in swirling convergences that make up about 40% of the ocean's surfaces. The impact of this pollution on marine life is deadly, with thousands of marine animals dying each year from ingestion of plastic or entanglement. The problem is growing, with the amount of plastic in our oceans doubling every six years. Poor waste management and littering are significant contributors to this issue, with plastic waste often ending up in rivers and the sea. While there are strategies to reduce plastic use and clean up efforts, urgent action is needed to address this epidemic.

Plastic pollution is a global crisis

The sources of plastic pollution are varied, with single-use packaging, consumer goods, clothing, and microplastics from products like toothpaste and face wash all contributing to the problem. Poor waste management, particularly in middle-income countries across Asia, is a significant factor, with plastic ending up in rivers and the sea. The fishing industry also plays a role, with an estimated 10% of ocean waste consisting of abandoned fishing gear.

The impact of plastic pollution is widespread and severe. Plastic can be found in every square mile of surface ocean on Earth, from the equator to the poles, and from Arctic ice sheets to the sea floor. It is estimated that there are 358 trillion microplastic particles floating on the ocean's surface, with countless more at the depths of the seabed. These microplastics are ingested by marine life, causing intestinal injuries and death, and transferring plastic up the food chain.

Urgent action is needed to address this crisis. Individuals can play a role by reducing their use of disposable and single-use plastic items, reusing and recycling, and participating in local clean-up efforts. However, systemic change is also necessary, with advocacy for regulations to manage and reduce plastic pollution and hold industries accountable for their contributions to this global issue.

The plastic pollution crisis in our oceans is a pressing issue that requires collective efforts from individuals, communities, and industries to mitigate and reduce the harmful impacts of plastic on our marine environments and wildlife.

Sources of plastic pollution

Plastic pollution in the ocean is a pressing issue that poses a threat to marine life and ecosystems. The sources of this pollution are diverse and far-reaching, with a significant portion originating from land-based activities and waste mismanagement. Here are the key sources of plastic pollution:

Land-Based Sources

The majority of plastic pollution in the ocean, ranging from 70% to 80% by weight, originates from land-based sources. This includes plastic waste that is improperly disposed of or mismanaged, eventually making its way into rivers and coastlines that flow into the sea. Poor waste management practices, particularly in areas with large populations and inadequate waste disposal systems, contribute significantly to this issue.

Marine Sources

About 20% to 30% of plastic pollution in the ocean comes from marine sources. This includes fishing gear, such as nets, lines, ropes, and abandoned vessels. The fishing industry is a significant contributor, with estimates suggesting that 10% of ocean waste is "ghost gear"—fishing equipment lost or discarded at sea. Some of these nets can be kilometres long, trapping marine life and causing entanglement and death.

Single-Use Plastics

The prevalence of single-use plastics in our daily lives cannot be understated. From packaging to consumer goods, the convenience of disposable plastics has led to a severe pollution problem. More than half of the plastic we consume is used only once before being discarded, ending up in landfills and the marine environment. Single-use plastics, such as food wrappers, beverage bottles, grocery bags, straws, and take-out containers, are among the top contributors to ocean plastic pollution.

Microplastics

Microplastics, tiny plastic particles less than 5mm in size, are another significant source of pollution. They can form when larger plastics break down, or they can be produced as small plastics like microbeads found in personal care products. These microplastics are easily ingested by marine life and can have detrimental effects on ecosystems.

Global Trade and Shipping

The global trade of plastic waste also contributes to ocean plastic pollution. While Asia is the largest recipient of plastic waste, it's important to note that many European countries ship their waste to these regions. This complex web of international waste trade makes it challenging to address the issue effectively.

Impact of plastic pollution on wildlife

Plastic pollution in the ocean has become a global crisis. Billions of pounds of plastic can be found in swirling convergences that make up about 40% of the world's ocean surfaces. According to the Washington Post, the number of plastic particles in the sea doubles every six years, and there are now 15-51 trillion pieces of plastic in the oceans, with an estimated 358 trillion microplastic particles floating on the surface. Marine life, from microscopic animals to large predators, is severely impacted by this pollution.

Plastic pollution affects marine life in two main ways: ingestion and entanglement. Marine animals can easily mistake plastic debris for food, leading to intestinal injury and death. Fish in the North Pacific ingest 12,000 to 24,000 tons of plastic each year, causing intestinal injuries and transferring plastic up the food chain. Research indicates that half of the sea turtles worldwide have ingested plastic, choking or starving them by creating a false sense of fullness. Plastic ingestion also reduces the storage volume in the stomach, causing starvation, as seen in hundreds of thousands of seabirds found dead with stomachs full of plastic.

Endangered wildlife, such as Hawaiian monk seals and Pacific loggerhead sea turtles, are among the nearly 700 species that eat and get entangled in plastic litter. Large amounts of plastic debris have been found in the habitats of these critically endangered seals, including areas that serve as pup nurseries. Entanglement in plastic debris has also led to injuries and deaths in the endangered Steller sea lion, with packing bands being the most common entangling material.

The impact of plastic pollution extends beyond the ocean to terrestrial animals and humans. Microplastics leech into soil and water sources, leading to a decline in species that live below the surface, such as mites, larvae, and other tiny creatures. Chlorinated plastic can release harmful chemicals into the surrounding soil and groundwater, contaminating the food we grow and the wildlife that consumes it. According to Greenpeace, fruits like apples and pears have been found to contain microplastics.

How to reduce plastic pollution

Plastic pollution in the oceans is a pressing issue that poses a serious danger to marine life, the climate, and human health. It is estimated that there are 15-51 trillion pieces of plastic in the world's oceans, with around 80% of marine plastic pollution originating on land. To reduce plastic pollution, several measures can be taken:

Reduce Plastic Consumption

The first step is to reduce the use of disposable and single-use plastic items. This includes items such as plastic packaging, consumer goods, and clothing that sheds microplastic fibers. Instead, opt for reusable alternatives, such as water bottles, containers, and shopping bags.

Reuse and Recycle

Reuse plastic items whenever possible, and recycle them when they can no longer be used. Check with your local recycling program to find out which types of plastic they accept. Also, consider purchasing products made from recycled plastic materials.

Proper Waste Disposal

Ensure that plastic waste is disposed of properly. Do not litter and participate in local clean-up initiatives to remove plastic litter from your community and prevent it from reaching the ocean.

Support Regulations and Initiatives

Support regulations and initiatives that aim to address plastic pollution. This includes advocating for policies that regulate plastics as pollutants and promote proper waste management practices.

Educate and Raise Awareness

Educate yourself and others about the impact of plastic pollution and the importance of reducing, reusing, and recycling plastic waste. Spread awareness about the dangers of plastic pollution to marine life and the environment.

Alternative Products

Opt for products that use minimal or no plastic packaging. Support businesses that prioritize sustainable practices and offer plastic-free alternatives.

By implementing these measures, we can collectively work towards reducing plastic pollution and mitigating its harmful effects on our oceans and the environment.

The future of ocean plastic pollution

By 2050, it is estimated that there will be more plastic in the oceans than fish, with plastic production projected to triple by that time. This poses a dire threat to marine ecosystems, as plastic pollution has already led to the deaths of thousands of seabirds, sea turtles, seals, and other marine mammals through ingestion and entanglement. The problem is not limited to the oceans, as microplastics are also making their way into our food systems, with potential unknown consequences for human health.

To address this growing crisis, a multifaceted approach is necessary. Firstly, reducing plastic consumption and improving waste management practices are crucial. This includes promoting reusable and recycled products, properly disposing of waste, and participating in local clean-up efforts. Additionally, advocating for policy changes and regulations that address plastic pollution as a hazardous form of waste is essential. Holding companies accountable for their plastic waste and runoff is also vital to reducing plastic pollution at its source.

Furthermore, a shift in perspective is needed, where waste is viewed as a resource rather than simply something to be discarded. This could potentially open up new avenues for waste management and reduction. Additionally, addressing the issue of plastic waste on a global scale is critical. While the epicentre of plastic pollution is currently in Asia, with five countries contributing 60% of plastic waste in the ocean, it is important to recognise that waste management and consumption patterns vary worldwide. Collaborating with countries that are major contributors to ocean plastic pollution and providing support for improved waste management infrastructure is essential.
