How to Prevent Coastal Water Pollution

Reduce plastic waste

Plastic waste is a major component of marine litter, with plastic bottles, bags, straws, utensils, and packaging all contributing to the problem. To reduce plastic waste and prevent coastal water pollution, several measures can be taken:

Reduce, Reuse, and Recycle:

• Avoid single-use plastics: Choose reusable water bottles, shopping bags, coffee cups, and food storage containers instead of disposable plastic ones.
• Reuse and recycle plastic items whenever possible: For example, plastic bottles can be reused, and recycling practices can be improved to reduce plastic waste.
• Refuse plastic utensils when dining out: Opt for reusable metal utensils instead.
• Avoid products with plastic microbeads: Check cosmetic ingredient labels for "polyethylene" and "polypropylene" to identify and avoid products containing microplastics.

Improve Waste Management:

• Properly dispose of waste: Ensure that waste is disposed of in designated bins and recycle whenever possible.
• Support local and national initiatives: Engage in community-led cleanup programs and support government efforts to improve waste management infrastructure.
• Address uncollected waste: Advocate for improved waste collection services, especially in developing countries, to prevent plastic waste from reaching coastal waters.

Educate and Advocate:

• Spread awareness: Educate yourself and others about the impacts of plastic pollution on coastal waters and encourage sustainable alternatives.
• Support sustainable practices: Encourage businesses and industries to adopt sustainable practices and reduce the use of plastics in their operations.
• Integrate education into school curricula: Teach children about the importance of environmental protection and the impacts of plastic pollution on coastal ecosystems.

Reduce Plastic Use:

• Choose alternatives to plastic: Opt for products packaged in glass, metal, or paper instead of plastic whenever possible.
• Refuse plastic packaging: When purchasing items, try to avoid unnecessary plastic packaging and opt for products with minimal or recyclable packaging.
• Minimize the use of plastic straws: Unless necessary for medical reasons, avoid using plastic straws, and choose reusable metal or paper straws instead.

Avoid harmful products

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. This is projected to triple in the next 20 years.

To avoid contributing to plastic pollution, opt for reusable products over single-use plastic items. For example, you can use cloth bags, stainless steel water bottles, and containers. Avoid products containing plastic microbeads, often found in face scrubs, toothpastes, and body washes. Look for "polythelene" and "polypropylene" on the ingredient labels of your cosmetic products.

Choose natural and non-toxic products. One of the leading causes of ocean pollution is chemical spillages and non-point pollution (runoff). When it rains, excess water containing pollutants like fertilisers, pesticides, litter, and other soil contaminants can flow into rivers and streams, eventually reaching the ocean. To reduce the amount of harmful chemicals that enter the ocean, avoid using toxic chemicals in your garden. Instead, opt for harmless, natural alternatives.

Buy less plastic and choose sustainable seafood. Unsustainable fishing practices harm marine ecosystems and contribute to ocean pollution. Support responsible fishing practices by opting for sustainably caught seafood options.

Improve stormwater management

Stormwater runoff is rainwater contaminated with bacteria, toxic chemicals, oil, dirt, and trash that flows through storm drains into local waterways. This eventually ends up in the ocean, causing coastal water pollution. To improve stormwater management, the following actions can be taken:

Implement Stormwater and Storm Drain Filtration and River Mouth Trash Collection

This can prevent wastes such as macroplastics (littered items), microplastics (tire dust), and chemicals on roadways from flowing into rivers and, eventually, the ocean.

Regulate the Use of Nutrients, Pesticides, and Fertilizers

Nitrogen and phosphorus from fertilizers and sewage can cause harmful algal blooms, which deplete oxygen levels in coastal waters, suffocating marine life. Reducing the use of these chemicals and adopting organic alternatives can help prevent this.

Maintain Your Septic System

A leaking septic system can leach harmful bacteria into storm sewer systems and local waterways. Regular inspections, maintenance, and pumping are necessary to prevent this.

Properly Dispose of Hazardous Substances

This includes used motor oil, antifreeze, paint, cooking oil, grease, and other fluids. Many automotive repair shops will accept used motor oil, and local waste management services can provide guidance on disposing of other hazardous household chemicals.

Plant a Rain Garden or Use a Rain Barrel

These can help absorb and collect stormwater runoff, reducing the amount that flows into storm sewers and local waterways.

By implementing these measures, we can significantly improve stormwater management and reduce coastal water pollution.

Raise awareness

Raising awareness is a crucial step in preventing coastal water pollution. It is essential that people understand the impact of their actions and how pollution will ultimately affect us all. Public education through various platforms such as local television, radio, social media, and websites can play a significant role in spreading awareness. Educational institutions also have a vital role to play in teaching students about the environment and its importance to regional welfare. Ministries of education can introduce new material into school curricula, ensuring that future generations grow up with a strong understanding of environmental issues.

Public-private partnerships can be established to improve public awareness and promote proper waste disposal practices. These partnerships can also develop innovative approaches to reducing pollution. For example, the Solid Waste Management Guide for Developing Countries provides best practices for local decision-makers to improve solid waste management, addressing marine litter globally. Additionally, the Trash Free Waters International Implementation Guide offers guidance on involving stakeholders and prioritizing low-cost projects to tackle marine litter.

Community-led programs and initiatives can also play a vital role in raising awareness and taking action against coastal water pollution. Beach and harbor cleanup services, natural drainage systems, and urban design to prevent direct littering into waterways are all effective strategies that communities can implement. Furthermore, understanding key pollutants, identifying pollution hotspots, and recognizing their impacts on marine biodiversity, fisheries, and human health are essential steps in developing effective regional cooperation and policies.

Raising awareness about the economic impacts of marine pollution is also crucial. Common policy reforms and standards for measuring existing and potential losses can help prioritize changes in pollution control policies. By understanding the economic consequences, stakeholders can make more informed decisions and allocate resources effectively to address coastal water pollution. Public awareness campaigns can highlight the economic and environmental costs of pollution, encouraging individuals, businesses, and governments to take preventive action.

Implement better waste management

Implementing better waste management is crucial to preventing coastal water pollution. Here are some strategies to achieve this:

Public Education and Awareness

Educating the public about the impacts of marine pollution and promoting better waste management practices are essential. Utilizing platforms such as local television, radio, social media, and websites can help spread awareness and engage communities in the issue. Integrating environmental education into school curricula will ensure that future generations understand the importance of waste management and its impact on coastal ecosystems.

Reduce Plastic Waste

Plastic pollution is a significant contributor to coastal water pollution. Encouraging the reduction of single-use plastics, such as plastic bags, straws, plastic bottles, and packaging, is vital. Promoting reusable alternatives, such as metal utensils and bottles, can significantly reduce plastic waste. Implementing bans on certain single-use plastics, as seen in some Caribbean countries, can also be effective. Additionally, improving recycling systems and supporting innovations to prevent plastic from entering waterways are crucial steps.

Proper Waste Disposal and Collection

Ensuring proper waste disposal and improving waste collection systems are essential. This includes addressing the issue of uncollected waste, which is a significant source of land-based marine litter.
