Implement "Fishing for Litter" Programs

Collaborating with the fishing industry to collect marine litter can be an effective way to remove existing plastic and other waste from the ocean. "Fishing for Litter" programs can provide the necessary infrastructure and incentives for fishers to collect and dispose of waste responsibly, contributing to a cleaner marine environment.

Adopting green chemistry practices requires a combination of regulatory measures, research and development, and public-private partnerships. By implementing these steps, we can simultaneously reduce plastic pollution and other forms of ocean pollution, protecting marine ecosystems and human health for future generations.

Improve stormwater management

Stormwater management is implemented at the operational level through management plans, administrative regulations, and decisions of individual managers or institutions. Effective management is contingent on operational objectives that are linked to feasible and measurable indicators and reference levels.

Implement Stormwater and Storm Drain Filtration:

Stormwater and storm drain filtration can prevent wastes such as macroplastics (littered items) and microplastics (tire dust) from flowing into rivers and eventually reaching the ocean. This can be done through pretreatment systems, flow spreaders, sand beds, and underdrain piping, which can reduce Total Suspended Solids (TSS) by 80%.

River Mouth Trash Collection:

Implementing river mouth trash collection can help prevent wastes, such as macroplastics and microplastics, from flowing into the ocean. This can be done in addition to stormwater filtration to further reduce the amount of waste entering the ocean.

Regulate the Use of Nutrients and Pesticides:

The use of nutrients and pesticides can be regulated to ensure they do not enter the ocean through stormwater. For example, the cultural norm of having a manicured lawn can increase the use of pesticides, herbicides, and fertilizers, which can eventually find their way into water bodies.

Implement Green Stormwater Infrastructure:

Green stormwater infrastructure mimics natural processes by encouraging stormwater to infiltrate the ground by slowing down flows and filtering out pollutants. Constructed wetlands, for example, can remove more than 70% of metal pollution in stormwater.

Street Sweeping:

Street sweeping can effectively remove pollutants from stormwater. Studies have shown that street sweeping can reduce Total Suspended Solids (TSS) by up to 78%.

Develop Scale-Appropriate Operational Objectives:

Clear and specific operational objectives are essential for effective stormwater management. These objectives should be measurable, achievable, realistic, and time-bound. They should also be linked to specific management actions and ecological outcomes.

Increase Cross-Scale Collaboration:

Collaboration across different scales, such as local, regional, and national levels, is crucial for successful stormwater management. This includes collaboration between governments, organizations, and individuals to address the complex and unpredictable mixtures of chemicals found in urban stormwater.

Implement Stormwater Credit Programs:

Cap and trade policies targeting total daily maximum loads (TMDLs) at the catchment or watershed scale can encourage management performance and progress toward meeting operational objectives. This can also promote cross-sector collaboration and integrated credit trading among polluters.

Ban plastic bags

Plastic pollution is a significant threat to ocean health, with millions of tons of plastic entering the ocean each year. Plastic debris breaks down into microplastics, which are ingested by marine animals, causing harm and even death. One of the most common forms of plastic pollution is plastic bags, which are often mistaken as food by whales and turtles.

Banning plastic bags is an effective way to reduce plastic pollution in the ocean. Here are some reasons why banning plastic bags is a crucial step towards a healthier ocean:
