What You'll Learn
Reduce plastic waste
Plastic pollution is one of the greatest threats to ocean health. It takes hundreds of years for plastic to fully degrade, and during this time, it leaches toxic chemicals. Marine animals often mistake plastic for food, and plastic pollution mars beaches, coastlines, and dive sites.
Reducing plastic waste is key to tackling this issue. Firstly, avoid single-use plastics such as plastic bags, straws, utensils, and bottles. Opt for reusable alternatives instead. You can also reduce plastic waste by avoiding products that contain plastic microbeads, often listed as "polyethylene" or "polypropylene" on cosmetic ingredient labels.
Recycling is another important way to reduce plastic waste. While it won't solve the plastics crisis, it helps reduce the impact of plastic on the environment. Check the number on the bottom of containers to see if they can be recycled. Urge local officials to support legislation that discourages plastic bag use, following the example of over 500 cities that have already done so.
Additionally, choose organic fertilizers over chemical fertilizers, as excess chemicals can make their way into the oceans. Finally, stay informed about plastic pollution and educate others. By making a few small changes, we can all play a part in reducing plastic waste and protecting our oceans.

Improve wastewater systems
Improving wastewater systems is crucial to reducing human marine pollution. Here are some ways to achieve that:
Upgrade Wastewater Infrastructure
Investing in modern wastewater treatment plants with advanced technologies can effectively remove pollutants, including microplastics, chemicals, and nutrients, before they reach the oceans. Upgrading infrastructure ensures that wastewater treatment facilities can handle the waste generated by growing populations, reducing the risk of untreated sewage discharge due to overwhelmed or ageing systems.
Implement Strict Regulations and Policies
Governments and regulatory bodies should establish and enforce stringent regulations to minimize the dumping of harmful substances into the oceans. This includes regulating the disposal of materials like dredged materials, fish wastes, and sewage sludge, as well as implementing policies that require the removal of microplastics during wastewater treatment.
Improve Waste Management
Encouraging the use of eco-friendly and non-toxic products in households can significantly reduce the amount of harmful chemicals that enter wastewater systems. Promoting sustainable practices, such as using reusable bags, bottles, and containers, opting for natural cleaning products, and supporting responsible fishing practices, can lessen the pollution burden on wastewater systems.
Enhance Sanitation Globally
According to the World Health Organization (WHO), billions of people lack access to safe sanitation services, contributing to marine pollution. Increasing access to improved sanitation facilities and ensuring proper waste treatment can help reduce the amount of untreated sewage that ends up in the oceans, especially in low- and middle-income countries.
Increase Funding for Ocean Sewage Pollution Research and Solutions
Ocean sewage pollution has received relatively limited philanthropic funding compared to other environmental causes. By increasing investment in research and solutions for ocean sewage pollution, we can develop and implement more effective measures to treat and reduce sewage pollution entering marine ecosystems.

Use eco-friendly products
Using eco-friendly products is a great way to reduce human marine pollution. Plastic pollution is one of the greatest threats to ocean health, with between 4 and 12 million metric tons of plastic entering the ocean each year. This plastic pollution comes from a combination of skyrocketing plastic production, low recycling rates, and poor waste management practices.
One way to reduce plastic pollution is to opt for reusable products over single-use items. For example, instead of using plastic bags, you can use a cloth bag, and instead of using single-use plastic bottles, utensils, and straws, you can use reusable stainless steel or glass alternatives. You can also avoid products that contain plastic microbeads, which are commonly found in face scrubs, toothpastes, and body washes. These microbeads are tiny plastic particles that are not effectively filtered out by sewer systems, and thus easily enter our oceans and affect marine life.
Another way to use eco-friendly products to reduce marine pollution is to choose natural cleaning and self-care products. Many traditional cleaning products contain harmful chemicals that can end up in the ocean and damage marine ecosystems. Instead, opt for natural and biodegradable cleaning products that are less likely to harm marine life. Similarly, many self-care and beauty products contain harmful chemicals that can be toxic to marine life. Choose non-toxic health and beauty products to reduce the number of harmful chemicals you release into the environment.
Additionally, you can reduce marine pollution by buying sustainable seafood. Unsustainable fishing practices harm marine ecosystems and contribute to ocean pollution. By choosing sustainably caught seafood, you can support responsible fishing practices and reduce the impact of fishing on marine environments.
Finally, you can reduce pollution by shopping organic and reducing your use of toxic chemicals in your garden. Excess chemical fertilizer can make its way into the oceans, so choosing organic fertilizers and using them sparingly can help reduce marine pollution. Additionally, challenging the cultural norm of having a perfectly manicured lawn can reduce the use of toxic chemicals in gardens. Instead of using harmful pesticides and herbicides, opt for harmless, natural alternatives that are less likely to damage marine ecosystems.

Improve solid waste management
Marine pollution is a pressing issue that poses a threat to marine ecosystems, human health, and economic activities. One significant contributor to this problem is inadequate solid waste management. To address this challenge, it is essential to implement strategies that improve solid waste management practices. Here are some detailed suggestions to enhance solid waste management and mitigate marine pollution:
Firstly, it is crucial to establish robust systems for solid waste collection, transportation, recycling, reuse, and final disposal. This involves investing in the necessary infrastructure and equipment to efficiently collect, transport, and process solid waste. Developed countries can assist developing nations in this regard through knowledge sharing and capacity building. For instance, the US Environmental Protection Agency (EPA) has developed a Solid Waste Management Guide for Developing Countries, offering guidance on best practices for local decision-makers to improve solid waste management.
Secondly, addressing marine litter, particularly plastic waste, is essential. Plastic waste, including single-use plastic items like bags, bottles, and containers, constitutes a significant portion of marine litter. To tackle this, individuals can opt for reusable alternatives, such as switching from single-use plastic bottles to reusable ones. Governments and organizations can also implement policies and projects to reduce plastic pollution, such as the Trash Free Waters International Implementation Guide, which provides strategies to address marine litter.
Thirdly, proper waste disposal and dumping regulations are critical. The EPA, for instance, designates ocean disposal sites and manages the times, quantity, and characteristics of materials disposed of at these sites. They also monitor the dumping process to ensure it does not endanger human health or the environment. Additionally, the EPA provides technical support and collaborates with other agencies to address marine pollution issues that arise during and after large-scale emergencies, such as oil spills.
Lastly, public-private partnerships and community engagement are vital. Solid waste management requires collaboration between governments, private entities, and local communities. The Caribbean Environment Programme (CEP), for instance, emphasizes the importance of addressing solid waste and marine litter through public-private partnerships. Community-based efforts, such as those supported by the US Peace Corps, empower local communities to implement small-scale projects that address solid waste and marine litter at the grassroots level.
By implementing these measures and fostering cooperation among various stakeholders, we can significantly improve solid waste management and, consequently, reduce marine pollution.
