For example, implementing bans or taxes on single-use plastic items, such as plastic bags, takeout containers, and bottles, can be an effective way to reduce plastic consumption and encourage the use of reusable alternatives. Extended producer responsibility (EPR) legislation, which holds plastic producers and distributors accountable for their products and packaging at the end of their life cycle, is another legislative approach that can drive change.

Finally, technological advancements and innovative solutions are being developed to address plastic waste. For instance, the Dutch nonprofit Ocean Cleanup has designed a system that uses a large floating net-like barrier to collect plastic from the ocean's surface. While this method has faced some criticism, it has successfully removed a significant amount of plastic from the Great Pacific Garbage Patch. Other technologies, such as river cleanup systems, solar-powered vessels, and bubble barriers, are also being employed to intercept plastic waste before it reaches the ocean.

By combining individual actions, legislative changes, and technological solutions, we can make significant progress in reducing plastic production and waste, ultimately contributing to a cleaner and healthier marine environment.

Improve wastewater systems

Improving wastewater systems is crucial in reducing marine pollution. Wastewater contains various pollutants, including plastics, chemicals, and other contaminants, which can have detrimental effects on both the environment and human health.

One of the main issues with wastewater is the presence of microplastics. These tiny plastic particles can pass through wastewater treatment plants (WWTPs) and end up in the ocean, contributing to the global microplastic pollution problem. While WWTPs can remove larger microplastic particles, they are often ineffective in capturing particles smaller than 100 μm. As a result, innovative technologies are needed to improve the removal of microplastics from wastewater.

Another issue with wastewater is the presence of contaminants, such as nutrients, pathogens, and solids. These contaminants can have severe impacts on marine life and ecosystems. For example, excess nutrients from agricultural runoff and wastewater can cause coral bleaching, decreased coral reproductivity, and algal blooms, which contribute to ocean warming and acidification. Wastewater can also introduce pathogens, such as viruses and bacteria, which can cause diseases in coral, fish, and shellfish.

To improve wastewater systems, there is a need for better wastewater infrastructure and treatment processes. This includes investing in new technologies to capture microplastics and remove contaminants before they are released into the ocean. Additionally, regulations and policies should be implemented to require the removal of microplastics and other pollutants during wastewater treatment. By improving wastewater systems, we can significantly reduce the amount of pollution entering our oceans and protect both the environment and human health.
