​This year the theme of World Earth Day is Planet vs Plastics. Plastic pollution, with 12 million tonnes entering our oceans annually, poses a severe threat to aquatic ecosystems and marine life. This issue predominantly stems from land-based sources, including plastic bags, bottles, and other forms of plastic waste, leading to the degradation of ocean health and safety.

Addressing ocean plastic pollution requires a multifaceted approach, focusing on reducing plastic marine pollution at the source and cleaning existing debris. Strategies include improving waste management to curb the flow of plastic waste into aquatic ecosystems and enhancing public awareness about the critical impact of microplastics on marine biodiversity.

The Scale of the Crisis

The escalation in global plastic production has been staggering, growing from a mere 2 million tonnes in 1950 to a colossal 460 million tonnes by 2019. This exponential increase has not been without dire consequences, particularly for our oceans. Each year, an estimated 8 to 12 million tonnes of plastic are dumped into the ocean, a figure that starkly highlights the severity of the crisis. This mass of waste primarily originates from land-based sources like urban runoff, littering, and inadequate waste disposal, further compounded by ocean-based sources such as the fishing industry.

The impact on marine life is both profound and devastating. Approximately 1.6 million square kilometres of the ocean are covered by the Great Pacific Garbage Patch, largely composed of plastics from fisheries. This floating debris not only poses physical risks through ingestion and entanglement but also introduces toxic pollutants into marine ecosystems. Shockingly, research indicates that 1 in 3 fish caught for human consumption now contains plastic, underscoring the direct threat to food safety and human health.

Moreover, the longevity of plastics, which can take 500-1000 years to degrade, means that the problem is not just immediate but will persist across centuries. Currently, a staggering 79% of plastic waste accumulates in landfills or the natural environment, with only 9% being recycled. This inefficiency in managing plastic waste exacerbates the pollution crisis, threatening not only marine life and ecosystems but also global human populations through impacts on coastal tourism, climate change, and overall ocean health.

Proven Strategies to Combat Oceanic Plastic Pollution

Reduce, Refuse, and Recycle

1. Minimize Single-Use Plastics: Start by refusing single-use plastics such as bags, bottles, and straws. Opt for reusable alternatives like cloth bags, metal bottles, and bamboo utensils.

2. Recycling and Proper Disposal: Ensure proper recycling of plastics by using local directories like Earth911 to find recycling centres. This helps keep recyclable plastics out of the ocean.

3. Participate in Local Cleanups: Engage in community beach cleanups or organize your own to physically remove plastic waste from marine environments.

Legislative Actions and Global Movements

1. Supporting Plastic Bans: Advocate for and support legislation that bans single-use plastics. Examples include Canada’s 2021 ban on plastic cutlery and straws, and the European Union’s directive to ban common beach litter items by 2021.

2. Extended Producer Responsibility (EPR): Push for policies where manufacturers are responsible for the lifecycle of their products, including post-consumer waste.

3. Global Treaties and Agreements: Promote global cooperation like the UNEA’s decision to negotiate a legally binding treaty on plastic pollution, aimed at significant international reductions.

Innovations in Product Design and Consumer Habits

1. Alternatives to Plastic Packaging: Use sustainable packaging options like beeswax wraps instead of cling film, and purchase products with minimal plastic packaging.

2. Biodegradable Options: Choose plastic-free teabags and chewing gum made from natural chicle to minimize your plastic footprint.

3. Product Redesign and Innovation: Support initiatives that redesign products to reduce waste, such as companies creating fully recyclable or biodegradable items.

Individual and Community Actions

Refusing and Reducing Plastic Use

To combat plastic pollution effectively, individuals and communities play a pivotal role. Starting with simple steps, such as refusing single-use plastics and opting for reusable items like water bottles, shopping bags, and straws, can significantly reduce the amount of plastic waste entering our ecosystems. It's also beneficial to purchase products with minimal or no plastic packaging and choose alternatives for items typically containing microplastics, such as certain cosmetics and personal care products.

Participating in Cleanup Initiatives

Active participation in local cleanups, whether at beaches, rivers, or urban areas, is crucial for removing existing waste and preventing future pollution. These activities not only help clean our environment but also raise public awareness about the severity of plastic pollution. Communities can organize these events with local schools, businesses, and non-profits to increase impact. Additionally, supporting technologies like river barriers and innovative projects like the Bubble Barrier in Amsterdam can amplify these efforts.

Advocacy and Education

Educating oneself and others about the impacts of plastic pollution and staying informed on legislative measures are powerful tools for change. By advocating for policies that restrict single-use plastics and improve waste management, individuals can influence larger systemic changes. Supporting organizations dedicated to fighting plastic pollution, such as the Oceanic Society or Plastic Pollution Coalition, through donations or volunteer work, also contributes to a broader impact. Sharing knowledge and resources within one’s network can further amplify the reach and effectiveness of these actions.

Moving Towards Policy and Global Solutions

Global Policies and Treaties

The urgency to tackle plastic pollution has led to significant strides on the policy front globally. The 2021 Break Free From Plastic Pollution Act in the United States sets a precedent by aiming to curtail plastic waste comprehensively. Concurrently, the Extended Producer Responsibility (EPR) legislation is gaining traction, holding manufacturers accountable for the lifecycle of their products, including disposal. On a broader scale, the Global Plastics Treaty, endorsed by 175 member states, marks a critical step towards reducing global plastic pollution, signalling a unified international commitment.

National and Regional Initiatives

Various countries are implementing robust measures to mitigate plastic pollution. The European Union's Marine Strategy Framework Directive is a prime example, aiming for a good environmental status of European seawaters by addressing marine litter. Similarly, economic incentives like taxes on plastic bags are being adopted in several nations to discourage their use and reduce marine pollution. Notably, Canada and the EU are investing in waste collection infrastructure in Southeast Asia, a region significantly impacted by oceanic waste, to improve waste management and reduce plastic discharge into the ocean.

Supportive Actions and Collaborative Efforts

Support structures and collaborative initiatives play a pivotal role in combating plastic pollution. The Aquarium Conservation Partnership in the U.S. is persuading businesses to reduce plastic usage, starting with straws. The New Plastics Economy Global Commitment and the University of Portsmouth’s Revolution Plastics Initiative both push for a circular economy and sustainable plastic use. Furthermore, the Global Partnership on Plastic Pollution and Marine Litter, led by the United Nations Environment Programme, is fostering international collaboration to prevent marine litter, showcasing the power of collective global action in addressing plastic pollution.
