What You'll Learn
Reduce plastic waste
Plastic pollution is one of the greatest threats to ocean health. It is estimated that 1 trillion plastic bags are used worldwide each year, and plastic debris can take hundreds of years to break down into microplastics. These microplastics are ingested by marine animals, causing health issues and even death.
To reduce plastic waste entering the ocean, individuals can make small changes to their daily routines. For example, instead of using single-use plastic bottles, utensils, straws, and bags, opt for reusable alternatives. When it comes to bottles, choose BPA-free or glass options, and for straws, silicone or metal varieties are great substitutes. These simple swaps will help keep plastics out of landfills and oceans.
Another way to reduce plastic waste is to cut down on the overall amount of plastic you throw away and bring reusable bags when shopping. This can be challenging, as plastic is prevalent in many products, but being mindful of product packaging and choosing alternatives with less plastic can make a difference.
Additionally, individuals can advocate for and support initiatives that improve wastewater management and stormwater filtration systems. These systems can prevent plastic litter and microplastics from entering rivers and, eventually, the ocean. Supporting regulations on the use of nutrients and pesticides can also help reduce plastic pollution, as these chemicals can enter the ocean through stormwater and contribute to harmful algal blooms.
Finally, participating in beach clean-up programs and volunteering in the community can help remove plastic litter from beaches and raise awareness about pollution. These collective efforts can significantly reduce plastic waste in the marine environment.

Avoid single-use plastics
Plastic pollution is one of the greatest threats to ocean health worldwide. Single-use plastic products (SUPs) are a major contributor to this, as they are used once or for a short period of time before being discarded. These products, such as bags, bottles, wrappers, and straws, often end up in our oceans, harming marine life and the environment.
To avoid single-use plastics, it is important to make conscious choices and adopt sustainable alternatives. One effective way is to carry reusable bags when shopping. Reusable totes are more environmentally friendly than plastic bags, even if a paper bag may need to be reused several times to have a lower environmental impact. You can also invest in a metal or glass straw that can be washed and reused, instead of single-use plastic straws.
Another way to reduce single-use plastic consumption is to cook at home more often and store leftovers in the freezer. This reduces the need for takeout containers, which are often made of plastic. Composting food waste is another way to reduce plastic waste, as it shrinks your overall waste output.
When shopping, avoid individually packaged goods, such as snack packs, and opt for products with minimal packaging. Zero-waste shops are a great alternative, as they encourage you to bring and fill your own containers. Buying products with recycled content and sourcing locally can also help reduce the environmental impact of single-use plastics.
Finally, it is important to understand that recycling alone cannot solve the plastics crisis. However, recycling can reduce the footprint of the plastic we use. Polyethylene terephthalate, the material commonly used for water and soda bottles, can be recycled into new products. But it's important to note that the majority of recycling centres do not accept small single-use plastic items like straws, bags, and cutlery, as they can fall into the machinery.

Improve wastewater management
Improving wastewater management is crucial to reducing marine pollution. Wastewater is a significant source of marine pollution, as it contains various pollutants, including plastics, chemicals, and other contaminants. These pollutants can have detrimental effects on marine life and ecosystems. Here are some ways to improve wastewater management and mitigate marine pollution:
Understand Your Local Water System
Knowing where your water comes from and how it is treated is essential. Learn about the wastewater treatment processes in your area and whether the treated water is discharged into nearby waterways. Understanding the unique qualities of your local water system will help you identify areas where you can reduce your contribution to water contamination.
Support Wastewater Infrastructure Improvements
Advocate for investments in wastewater infrastructure upgrades and improvements. Aging and overwhelmed sewage treatment systems can release untreated wastewater, contributing to marine pollution. By supporting initiatives for modern and efficient wastewater treatment facilities, you can help reduce the amount of untreated pollutants discharged into marine environments.
Properly Dispose of Hazardous Substances
Many household chemicals and substances can be harmful if they end up in the wastewater stream. Properly dispose of items such as chemical cleaners, oils, herbicides, pesticides, and non-biodegradable products. Ensure that these substances do not go down the drain or enter stormwater drains, as they can contaminate water bodies and harm marine life.
Choose Eco-Friendly and Non-Toxic Products
Opt for eco-friendly, natural, and non-toxic health, beauty, and cleaning products. Many traditional products contain harmful chemicals that can pollute oceans and harm marine life. By choosing biodegradable and non-toxic options, you can reduce the amount of chemical pollutants entering the wastewater system and, ultimately, the oceans.
Practice Responsible Waste Management
Proper waste management is crucial in preventing marine litter. Dispose of waste responsibly, and support initiatives for improved solid waste management in your community and globally. Reduce, reuse, and recycle whenever possible, especially with plastic products. Participate in beach and river clean-up efforts to remove plastic waste and raise awareness about the importance of proper waste management.
By implementing these measures and advocating for improved wastewater management practices, we can significantly reduce the impact of wastewater pollution on our oceans and marine ecosystems.

Reduce nonpoint source pollution
Nonpoint source pollution is a significant issue that can have detrimental effects on marine life and the environment. While the exact locations of nonpoint source pollution are challenging to identify, certain environments and operations are known to produce high volumes of pollution. Here are some ways to reduce nonpoint source pollution:
Riparian Corridors and Buffer Strips
Riparian corridors are buffer zones between used land and streams, often planted with vegetation. These corridors can regulate water temperature, protect banks from erosion, and filter pollutants from stormwater. Establishing and maintaining riparian corridors can be done by allowing natural growth, planting native vegetation, and adding trees and bushes. Buffer strips, or grass strips, can also be planted between impervious surfaces like parking lots and sidewalks and bodies of water. These strips absorb soil, fertilizers, pesticides, and other pollutants, preventing them from reaching the water.
Responsible Land Management
In urban areas, impermeable pavement increases stormwater runoff, leading to downstream flooding, erosion, and nonpoint source pollution. To mitigate this, individuals can implement solutions like planting rain gardens, connecting downspouts to rain barrels for irrigation, and using porous pavement that allows stormwater to infiltrate the ground. Additionally, conservation practices like conservation tillage, crop nutrient management, and integrated pest management can reduce erosion and pesticide usage, minimizing agricultural runoff.
Livestock Management
Livestock can contribute to water pollution by trampling stream banks and depositing feces, leading to higher E. coli levels. To reduce this impact, farmers can limit livestock access to streams and rivers with fences and provide alternative drinking water sources. Implementing rotational grazing systems and allowing vegetation to grow can also reduce pasture erosion.
Proper Waste Disposal
Improper disposal of household and agricultural waste can contribute to nonpoint source pollution. It is essential to keep litter, pet waste, leaves, and debris out of street gutters and storm drains. Oils, chemicals, herbicides, pesticides, and cleaning products should be disposed of at designated drop-off sites or hazardous waste programs. Proper maintenance of septic tanks and vehicles can also prevent leaks and spills.
Community Initiatives
Volunteer groups, water quality professionals, and local communities can work together to clean up and protect lakes, rivers, streams, and wetlands. Individuals can advocate for the establishment of household hazardous waste collection programs and support local initiatives. Additionally, following "catch and release" fishing practices, volunteering for beach and community cleanups, and choosing sustainable seafood can positively impact marine environments.

Choose organic fertilisers
Marine pollution is a pressing issue, with plastic pollution being one of the greatest threats to ocean health. Another significant contributor to marine pollution is chemical agriculture, which includes the use of synthetic herbicides, fertilisers, and pesticides. These chemicals can have detrimental effects on marine life and ecosystems. To mitigate this issue, choosing organic fertilisers is a crucial step in the right direction.
Organic fertilisers play a vital role in protecting our oceans by minimising or eliminating the runoff of synthetic chemicals into waterways and, subsequently, the ocean. Chemical fertilisers contain toxic substances that can contaminate water bodies through a process known as runoff. Runoff occurs when more water enters the soil than it can absorb, causing excess water to flow into nearby rivers or oceans, carrying harmful chemicals with it. This toxic runoff has been recognised as a severe issue by scientists, who advocate for stricter regulations to safeguard marine ecosystems.
Organic fertilisers help reduce the negative impact of chemical agriculture on marine life. Unlike synthetic fertilisers, organic fertilisers do not contain toxic chemicals that can harm marine organisms. They also contribute to improving soil health, particularly topsoil, which is essential for preventing water pollution. By enhancing the quality of the soil, organic fertilisers reduce the amount of sedimentation and pollution that enters waterways, thereby protecting water habitats and the species that depend on them.
Additionally, organic fertilisers do not cause the same level of nutrient loss as chemical fertilisers. Chemical fertilisers can introduce excess nitrogen and phosphorus into farm fields, which can then be washed into nearby waterways. This excess of nutrients stimulates the growth of microorganisms, reducing the dissolved oxygen levels in the water and creating hypoxic or "dead zones" where marine life cannot survive. Organic fertilisers, on the other hand, do not contribute to the creation of these dead zones and help maintain a healthy balance of nutrients in the water.
By choosing organic fertilisers, we can significantly reduce the pollution that ends up in our oceans. This simple switch encourages sustainable farming practices that protect marine life and ecosystems, ensuring a healthier future for our planet's waters and the countless species that depend on them.
