Ocean pollution is a pressing issue that poses serious threats to marine life, human health, and the environment. It is primarily caused by human activities, with personal waste being a significant contributor. This waste, including plastic and other pollutants, enters the ocean through various pathways, such as littering, improper waste management, and natural events. The impact of personal waste on ocean pollution is evident in the Great Pacific Garbage Patch, a collection of litter in the North Pacific Ocean, and the estimated 171 trillion plastic particles polluting the world's oceans. The sources of this pollution are diverse, ranging from single-use plastics to industrial fishing and manufacturing processes. With plastic production projected to increase, addressing personal waste management is crucial to mitigating ocean pollution and its far-reaching consequences.
What You'll Learn
Plastic waste
The majority of plastic pollution in the ocean is caused by littering, with only 9% of plastic waste being recycled globally. Improper waste management in many countries, including both developing and developed nations, has led to plastic pollution becoming a worldwide problem. Lower-income countries often have inefficient or non-existent garbage collection systems, while middle-income countries are struggling to keep up with increasing plastic consumption due to a lack of adequate waste management systems.
Once plastic waste enters the ocean, it is extremely difficult to retrieve. It breaks down into smaller pieces called microplastics, which spread throughout the water column and have been found in every corner of the globe, from Mount Everest to the Mariana Trench. These microplastics are consumed by marine organisms, leading to intestinal injuries and death, and transferring plastic up the food chain to bigger fish, marine mammals, and even human seafood eaters.
The impact of plastic waste on marine life is devastating. Seabirds, sea turtles, seals, and other marine mammals are killed each year after ingesting plastic or becoming entangled in it. Endangered species such as Hawaiian monk seals and Pacific loggerhead sea turtles are among the nearly 700 species affected by plastic litter. Plastic waste also alters habitats and natural processes, reducing ecosystems' ability to adapt to climate change and directly affecting millions of people's livelihoods, food production, and social well-being.
To address the issue of plastic waste in the ocean, it is crucial to improve waste management practices and reduce plastic consumption. This includes increasing recycling rates, properly disposing of plastic waste, and adopting reusable alternatives to single-use plastics. Global efforts, such as the UNEA-5.2 resolution "End plastic pollution: towards an International legally binding instrument," are also working towards addressing plastic pollution throughout its entire lifecycle, from source to sea.

Poor waste management
The impact of poor waste management is exacerbated by the durability of plastic products, which are designed to be strong, flexible, and long-lasting. As a result, plastic waste can persist in the environment for hundreds of years, breaking down into microplastics that are challenging to remove from the water column. These microplastics, smaller than 5mm in size, are spread by ocean currents and have been found in every region, from Mount Everest to the Mariana Trench.
Another consequence of poor waste management is the release of toxic chemicals into the ocean. This includes mercury from coal combustion and small-scale gold mining, as well as chemical fertilizers from industrialized agriculture. These pollutants contaminate marine ecosystems and harm marine life, with potential impacts on human health through the consumption of seafood.
Furthermore, poor waste management can lead to sewage and stormwater discharge into the ocean. Sewage contributes to ocean pollution, even though it has been banned in certain countries like the USA. Stormwater runoff carries pollutants from land, including oil, chemicals, and litter, into the ocean, adding to the overall degradation of marine environments.
To address the issue of poor waste management and reduce its impact on ocean pollution, several strategies can be implemented. These include improving waste collection and recycling infrastructures, promoting proper waste disposal through education and legislation, and supporting research and policies aimed at reducing plastic use and production. By combining these approaches, we can work towards minimizing the negative consequences of poor waste management on our oceans.

Nonpoint source pollution
NPS pollution has harmful effects on drinking water supplies, recreation, fisheries, and wildlife. It can come from many sources, including runoff from septic tanks, vehicles, farms, livestock ranches, and timber harvest areas. Personal waste, such as litter, pet waste, fertilizers, pesticides, and sediments, also contributes to NPS pollution when it ends up in street gutters and storm drains, which directly drain into lakes, streams, rivers, and wetlands.
The impact of NPS pollution on coastal areas has led to federal actions and programs, such as the Nonpoint Source Management Program and efforts to protect coastal waters. Additionally, individual habits play a crucial role in preventing NPS pollution. Citizens are educated about actions to reduce pointless pollution, such as keeping litter, pet waste, and leaves out of storm drains and properly disposing of household chemicals.
Furthermore, improper waste management and plastic pollution are significant contributors to ocean pollution. Plastic waste accounts for 80% of all marine pollution, with an estimated 8 to 10 million metric tons of plastic ending up in the ocean annually. This plastic pollution comes from disposable plastic items such as food wrappings, plastic bags, razors, and bottles, which are not properly disposed of and eventually make their way into waterways and the ocean.

Sewage and industrial waste
Industrial activities, such as offshore oil and gas production, shipping, and aquaculture, have a significant ecological footprint on the marine environment. Oil spills from shipping and offshore extraction are a major source of ocean pollution, damaging marine habitats and wildlife. Additionally, ballast water discharges, ship strikes, noise pollution, and dredging for shipping channels contribute to habitat destruction and marine mammal mortality. The aquaculture industry introduces invasive species, diseases, and chemical use, impacting wild fisheries and coastal habitats.
Another critical aspect of industrial waste is plastic pollution. Plastics leak into the oceans from thousands of sources worldwide due to improper waste management and inadequate waste collection systems. While high-income countries have effective waste management, middle-income countries with increasing plastic consumption and lacking infrastructure face challenges. Rivers are a significant pathway for plastic pollution, with 1000 rivers contributing to 80% of plastic emissions into the oceans.
To address sewage and industrial waste pollution, investments in infrastructure and sanitation facilities are crucial. Upgrading drainage systems and improving waste management practices can help reduce the volume of sewage and plastic waste entering our oceans, protecting marine life and ecosystems and ensuring a healthier environment for all.

Atmospheric pollution
The breakdown of waste releases gases such as methane, a major factor in global climate change. Methane is released as organic matter decomposes, and it has a warming potential over 80 times greater than carbon dioxide. Municipal solid waste landfills, accounting for 31% globally, are the third-largest source of human-related methane emissions in the US. Landfills also release carbon dioxide and other greenhouse gases into the atmosphere, contributing to global climate change. Poor waste management strategies, such as open dumps and burning sites, allow these gases to enter the atmosphere directly.
In addition to methane and carbon dioxide, waste disposal contributes to air pollution through the release of other harmful substances. For example, hazardous household waste, if not properly collected or managed, can cause health and environmental hazards. This includes corrosive, explosive, flammable, toxic, and reactive substances that can pollute the wider environment and affect human health. Open landfills and dumps can also lead to the escape of toxic chemicals and microplastics into the surrounding soil, groundwater, and waterways.
The impact of atmospheric pollution from waste disposal is worsened by the fact that nearly 50% of the world's waste is not managed properly. This results in waste ending up in places where it can cause air pollution, such as open dumps and burning sites. Improper waste management practices can also lead to the spread of pests, like rats, which flourish in dirty environments, and the contamination of drinking water sources.
To combat atmospheric pollution caused by personal waste, individuals, companies, and governments must take action. Individuals can reduce their waste, reuse and recycle, and separate their waste correctly. Companies can use less packaging, design easily recyclable products, and support improved waste management regulations. Governments can work with local waste teams to develop better waste management plans and improve waste-handling techniques to reduce the impact of waste disposal on the atmosphere.
