Preventing Marine Pollution: Strategies For A Cleaner Ocean

Marine pollution is a pressing issue that poses a severe threat to ocean health and the planet's wildlife. With plastic production skyrocketing and a lack of efficient waste management, it is estimated that between 4 and 13 million metric tons of plastic enter the ocean each year. This plastic pollution affects marine life, including sea turtles, whales, seabirds, fish, and coral reefs, and mars beaches and coastlines. To address this issue, it is crucial to focus on preventing plastic pollution and other forms of ocean pollution. This includes reducing plastic production and waste, improving wastewater and stormwater management, adopting eco-friendly products and practices, and supporting legislation and initiatives aimed at curbing plastic pollution. Individual efforts, such as reducing single-use plastic consumption and participating in beach cleanups, are important. However, they must be coupled with governmental and organisational actions to implement effective waste management systems and discourage plastic waste. By tackling the root causes of marine pollution and working together, we can protect the health and prosperity of marine ecosystems and the millions of people who depend on them.

Reduce plastic production and waste

Reducing plastic production and waste is one of the most important ways to prevent marine pollution. Plastic pollution is one of the greatest threats to ocean health, with skyrocketing plastic production, low levels of recycling, and poor waste management. Between 4 and 12 million metric tons of plastic enter the ocean each year, and this amount is projected to triple in the next 20 years.

On an individual level, there are several ways to reduce plastic waste. Firstly, avoid single-use plastics and opt for reusable alternatives. This includes refusing plastic bags, straws, takeout utensils, and containers, and instead carrying your own reusable versions, such as grocery bags, bottles, utensils, and coffee cups. Additionally, boycott products containing microbeads, as these tiny plastic particles can pass through water-treatment plants and end up in the oceans, where they are ingested by marine animals.

Another way to reduce plastic waste is to support legislation that curbs plastic production and waste. While individual efforts are important, they are not enough to solve the problem alone. Support local, national, and international legislation that reduces plastic production, improves waste management, and holds plastic producers accountable for the waste they generate. For example, the 2021 Break Free From Plastic Pollution Act in the United States is a federal bill addressing the plastic pollution crisis. Similarly, the UK's recent ban on a range of single-use plastic products is a positive step.

Improving wastewater infrastructure is also crucial in reducing plastic waste. Sewage pollution is a significant issue, and untreated wastewater contains plastics and other pollutants that pose risks to both the environment and human health. By improving wastewater systems, we can prevent plastic and other harmful substances from entering our oceans.

Finally, using eco-friendly products can significantly reduce plastic pollution. Opt for reusable bags, water bottles, and containers made from materials like cloth and stainless steel. Choose natural cleaning and beauty products with biodegradable ingredients, avoiding harmful chemicals that can damage marine ecosystems.

Improve wastewater systems

Improving wastewater systems is crucial in preventing marine pollution. Wastewater is a significant threat to nature and human health, and without proper treatment, it can contribute to habitat loss and extinction. Every day, 80% of the world's wastewater enters the environment untreated, endangering nature and public health. It introduces a cocktail of contaminants, including pathogens, pharmaceuticals, microplastics, heavy metals, and endocrine disruptors, which have far-reaching consequences for aquatic life and human food and water security.

To address this issue, it is essential to invest in and upgrade wastewater treatment infrastructure. The current systems in many places, such as London, are outdated and unable to handle the waste of growing populations. By improving wastewater infrastructure, we can effectively treat and manage wastewater, reducing the amount of untreated wastewater that ends up in our oceans. This includes upgrading old sewage systems and ensuring proper maintenance and expansion of wastewater treatment plants.

Additionally, implementing innovative and nature-based solutions can be highly effective. Constructed wetlands, for example, are engineered systems that use natural biological technologies, incorporating wetland vegetation, soils, and microorganisms to remove contaminants from wastewater. This approach has been successfully applied in places like the Dominican Republic and India, improving water quality and restoring wildlife habitats.

Another aspect of improving wastewater systems is raising awareness and education about wastewater pollution. Many people are unaware of the critical threat it poses to humans and natural systems. By collaborating with organizations, such as the Reef Resilience Network, and building partnerships, we can develop and disseminate educational resources and training programs to increase understanding and inspire action. This includes working across sectors to share research, tools, and best practices related to wastewater pollution, public health, and environmental protection.

Furthermore, policy reform is necessary to address wastewater pollution effectively. Many existing wastewater policies and regulations are inadequate and based on outdated science. Advocating for stronger legislation and working with policymakers to develop and implement regulations that address modern-day stressors and recognize the economic opportunity of wastewater resource recovery is essential. This includes holding industries accountable for their waste and promoting sustainable wastewater management practices.

Use eco-friendly products

Using eco-friendly products is an effective way to reduce marine pollution. This involves opting for reusable options over single-use items, such as cloth bags, stainless steel water bottles, and containers. By choosing reusable products, you can significantly reduce the amount of plastic waste that ends up in the ocean. Single-use plastics, such as plastic bags, water bottles, straws, and disposable cutlery, are a major contributor to marine pollution.

In addition to reusable items, you can also choose natural and biodegradable cleaning products. Many traditional cleaning products contain harmful chemicals that can damage marine ecosystems. Eco-friendly alternatives, made from natural ingredients, are safer for the environment and can effectively reduce pollution.

When it comes to seafood, it is important to buy sustainably caught options that support responsible fishing practices. Unsustainable fishing harms marine life and contributes to ocean pollution. By choosing sustainable seafood, you can help protect marine ecosystems and ensure the long-term viability of the fishing industry.

Another way to use eco-friendly products is to opt for non-toxic health and beauty products. Many self-care products contain chemicals that can be toxic to marine life. By choosing natural and non-toxic alternatives, you can take care of yourself while also protecting the ocean and its inhabitants.

Finally, when shopping for clothing, opt for natural fibres such as cotton and wool instead of synthetic materials. Synthetic fibres, such as nylon, acrylic, and polyester, are a significant source of microplastics in the ocean. These microplastics are released from our clothes and end up in the water supply, causing harm to marine life. By choosing natural fibres, you can reduce your impact on the environment and support a more sustainable fashion industry.

By incorporating these eco-friendly product choices into your daily life, you can make a significant contribution to reducing marine pollution and protecting our oceans.

Manage oil spills

Oil spills are a significant contributor to marine pollution and can cause severe damage to marine ecosystems. It is imperative that governments and industries take measures to prevent oil spills and respond quickly to contain and clean up any spills that occur.

To manage oil spills effectively, it is crucial to invest in spill response technology and improve safety standards for offshore drilling. This includes enforcing strict preventative regulations and addressing the root causes of spills, which are often human and organisational factors. Understanding these factors can help prevent future spills and minimise environmental damage.

For example, in Washington state, spills from small vessels like privately owned boats and fishing boats accounted for 75% of the oil spilled in local waters between 2006 and 2016. To prevent such incidents, boat owners and operators should prioritise proper vessel maintenance and emergency planning. This includes removing vessels from the water during hurricanes, identifying safe harbours, and checking anchors and lines.

Additionally, recreational boaters and small vessel operators can play a crucial role in preventing oil from entering the water. Staying on top of maintenance and being cautious during refuelling can help reduce oil pollution. It is also essential to dispose of oil and oily waste properly, avoiding dumping it into sewers or garbage, as this contributes to pollution.

By addressing oil spills through prevention, preparedness, and quick response, we can minimise the environmental, economic, and public health impacts of oil spills.
