What You'll Learn
Reduce plastic waste
Marine ecosystems are affected by plastic pollution, which poses a serious danger to marine life. Plastic pollution in the oceans is a significant issue as it takes hundreds of years to degrade, all the while leaching toxic chemicals. Plastic debris can cause the ingestion, suffocation, and entanglement of species. Wildlife such as birds, whales, fish, and turtles mistake indigestible plastic waste for food, which leads to starvation as their stomachs become filled with plastic. Plastic pollution also causes internal and external injuries that reduce the ability of these animals to swim and fly.
To reduce plastic waste, one can start by avoiding products that contain microbeads. Microbeads are tiny plastic particles found in some face scrubs, toothpastes, and body washes that enter oceans and waterways through sewer systems, affecting hundreds of marine species. It is important to check the ingredient labels of cosmetic products and avoid those containing "polyethylene" and "polypropylene".
Another way to reduce plastic waste is to opt for reusable products instead of single-use items. This includes choosing reusable bags, water bottles, and containers made from materials like cloth and stainless steel. Reusable options reduce the amount of plastic waste that ends up in the ocean and helps protect marine life.
Recycling is also an important strategy in reducing plastic waste. While it is not a complete solution to the plastic crisis, it helps reduce the footprint of our waste stream. Individuals can check the numbers on the bottom of containers to determine if they are recyclable in their locality. However, it is important to prioritize reduction and urge officials to implement policies that discourage plastic bag use, such as those in San Francisco and Chicago.
Beach and river cleanups are another direct way to reduce plastic waste and fight sea pollution. These cleanups not only remove plastic waste from the ocean but also help raise awareness and inspire others to take action. Supporting organizations like The Ocean Cleanup and Surfers Against Sewage, which undertake large-scale projects, can also make a significant impact.
Finally, it is important to advocate for stronger legal targets and put pressure on policymakers and industries to address plastic pollution. This includes pushing for ambitious reductions in plastic production, phasing out harmful subsidies, and eliminating products and chemicals that contribute to the plastic crisis. Collective action on a global scale is necessary to effectively tackle this issue.

Improve wastewater systems
Wastewater systems are a significant contributor to marine pollution, particularly in the case of microplastics. Without adequate treatment, wastewater can introduce pathogens, pharmaceuticals, microplastics, heavy metals, and endocrine disruptors into the marine environment, threatening aquatic ecosystems and contributing to biodiversity and habitat loss.
To improve wastewater systems and reduce their impact on marine life, several actions can be taken:
Upgrade Wastewater Treatment Plants
Upgrading to secondary and tertiary wastewater treatment methods can help filter out microplastics and improve marine water quality. For instance, many wastewater treatment plants in the Salish Sea are transitioning to these advanced treatment methods, which will significantly enhance their ability to capture microplastic particles.
Implement Innovative Technologies
There are promising technologies in development that can improve the removal of microplastics and other contaminants from wastewater. However, there is a lack of policies and regulations mandating the removal of microplastics during treatment. Incentivizing research and development through better policies and regulations can accelerate the adoption of innovative practices and technologies.
Public Awareness and Pressure
Public awareness and pressure on policymakers and industries can lead to more ambitious legal targets and stronger regulations. This can include supporting organizations dedicated to ocean conservation and participating in beach and river cleanups, which help remove plastic waste and raise awareness about the issue.
Beneficial Landscaping Techniques
Implementing beneficial landscaping techniques, such as rain gardens, rain barrels, green roofs, and permeable paving, can help reduce the need for chemical fertilizers and minimize runoff into ditches and storm drains. This, in turn, reduces the amount of pollution entering waterways and, ultimately, the ocean.
Proper Sewage Management
For boat owners, it is essential to properly manage sewage wastes. Treated or untreated sewage should never be discharged into waterways. Many marinas provide sewage pump-out services at low or no cost. Similarly, those with septic systems at home or in business settings should learn about their systems and maintain them properly.

Prevent oil spills
Oil spills are a significant contributor to marine pollution and can cause severe damage to marine ecosystems. While large spills like the 2010 BP Deepwater Horizon incident are rare, smaller spills from vessels and facilities are more common and can add up to significant pollution levels. To prevent oil spills, several measures can be implemented:
Regular Maintenance and Inspections
Boat owners and operators should perform regular maintenance on their vessels to reduce the risk of oil spills. This includes tightening bolts on engines, proper vessel upkeep, and planning for emergencies. Regular inspections of vessels, tanks, and transfer operations are crucial for early detection of potential issues.
Spill Prevention Plans and Regulations
Facilities that store and handle oil should have a Facility Response Plan (FRP) or Spill Prevention, Control, and Countermeasure (SPCC) plan in place. These plans outline specific rules, regulations, and procedures to prevent and contain oil spills. SPCC plans are required for facilities with specific storage capacities and those located near navigable waters.
Safety Standards and Training
Improving safety standards for offshore drilling and implementing strict preventative regulations can help reduce the risk of spills. Regular training and education for workers are essential to ensure they are equipped to handle oil properly and respond effectively in the event of a spill.
Quick Response and Containment
In the event of a spill, a quick response is critical to contain and clean up the oil before it spreads and causes further damage. Having the necessary cleanup equipment readily available is crucial for an efficient response.
Public Awareness and Pressure
Public awareness and pressure on policymakers and industries can lead to stronger legal targets and regulations to prevent oil spills. Staying informed about oil pollution issues and supporting organizations working on large-scale projects to combat marine pollution are also important.
By implementing these measures and working together, we can significantly reduce the number of oil spills and minimize their impact on marine ecosystems.

Proper waste management
Marine ecosystems are deteriorating due to increasing coastal development, marine litter, excess nutrients, untreated wastewater, and other pollution threats. Proper waste management is crucial in protecting these ecosystems.
Marine litter, largely caused by insufficient solid waste management, is a significant problem in the world's oceans. Uncollected waste, poor waste disposal practices, and illegal dumping are major sources of land-based marine litter. To combat this, individuals can start by reducing plastic consumption and properly recycling and disposing of waste. This includes opting for reusable products, such as cloth bags, stainless steel water bottles, and containers, over single-use plastic items. Additionally, avoiding products containing microbeads, found in some face scrubs, toothpastes, and body washes, is essential to reducing plastic pollution.
On a larger scale, governments and industries must take responsibility for improving waste management practices. This includes investing in recycling infrastructure, implementing regulations, and enforcing proper waste disposal procedures. The EPA, for example, has developed an International Marine Litter Toolbox to guide countries in addressing marine litter and improving solid waste management. They also work with other agencies to address marine pollution issues that arise during and after large-scale emergencies, such as oil spills.
Furthermore, it is imperative to address the issue of untreated wastewater, which significantly contributes to marine pollution. Proper wastewater treatment and disposal methods must be implemented and regulated to protect marine ecosystems. This includes establishing designated ocean disposal sites for various materials, such as dredged materials and fish wastes, and ensuring that these sites are carefully monitored to minimize any potential impacts on the marine environment.
By implementing these waste management strategies and working together on a global scale, we can significantly reduce the amount of pollution entering our oceans and protect marine ecosystems for future generations.
