Additionally, participating in beach and waterway cleanup events can help remove plastic pollution from oceans and prevent further contamination.

Beyond plastic pollution, there are various non-plastic pollutants that need to be addressed, such as nutrients like nitrogen and phosphorus, antibiotics, heavy metals, pesticides, oil, and gas. These substances enter the ocean directly or through rivers, stormwater, or wind. To improve waste management and reduce these pollutants, individuals can take several measures. This includes proper disposal of herbicides, pesticides, and cleaning products, as well as reducing the use of toxic chemicals in gardens and opting for harmless, natural alternatives.

At a larger scale, improving wastewater management is essential. Developing sustainable wastewater infrastructure can reduce plastic and nutrient pollution, improving the health of fisheries and coral reefs. This involves ensuring access to controlled waste disposal facilities, as untreated wastewater contains pollutants like plastics, chemicals, and pathogens that pose risks to human and environmental health. Stormwater management is another crucial aspect, including implementing stormwater and storm drain filtration and river mouth trash collection to prevent wastes and chemicals from reaching oceans.

Furthermore, improving waste management in the fishing industry is vital. Abandoned, lost, or discarded fishing gear, known as "ghost gear," is one of the most deadly forms of marine plastic debris, impacting a significant percentage of marine mammals, seabirds, and sea turtles. Working with fishers to keep ghost gear out of the ocean not only benefits marine life but also improves the coastal environment for fishing communities.

Additionally, individuals can contribute by buying sustainable seafood. Unsustainable fishing practices harm marine ecosystems and contribute to ocean pollution. Opting for sustainably caught seafood options supports responsible fishing practices and helps reduce the pollution associated with unsustainable fishing.

Reduce oil pollution

Oil pollution is a significant threat to the ocean and the environment. Oil spills are a major source of oil pollution, and they can have devastating effects on marine life, ecosystems, and human health. Oil spills can occur due to various factors, including accidents, severe weather, and improper waste disposal. To reduce oil pollution and protect our oceans, several preventive measures and regulatory actions can be implemented:

Prevent Oil Spills

The first step is to prevent oil spills from occurring. This involves proper vessel maintenance and emergency preparedness by boat owners and operators. When facing challenging conditions, such as severe weather, it is crucial to remove vessels from the water, identify safe harbors, and secure anchors and lines. By taking proactive measures, the risk of oil spills can be significantly reduced.

Improve Wastewater Management

Implementing sustainable wastewater management practices is essential. Improving wastewater infrastructure and treatment processes can prevent the discharge of oily waste and other pollutants into water bodies that eventually flow into the ocean. This includes regulating and treating industrial and municipal wastewater to remove oil and other contaminants before discharge.

Promote Sustainable Transportation

Encouraging the use of fuel-efficient vehicles, carpooling, and alternative modes of transportation, such as biking or walking, can help reduce the demand for oil. By decreasing our reliance on oil, we can lower the risk of oil spills and reduce the overall impact of oil transportation and production on the environment.

Proper Disposal of Oil and Oily Waste

It is crucial to dispose of oil and oily waste responsibly. Dumping oil into sewers or garbage can contribute to pollution. Instead, individuals should properly recycle or dispose of oil at designated facilities. This helps prevent oil from entering water bodies and the ocean, reducing the impact on marine life and ecosystems.
