For many families, the ocean provides a peaceful and meaningful setting to honor a loved one through ash scattering or burial at sea. Because these memorials take place in a natural environment, protecting the health of our oceans is an important responsibility.
Plastic pollution has become one of the most significant environmental challenges affecting marine ecosystems today. Understanding how ocean pollution impacts marine life helps families and service providers make thoughtful choices that respect both the ocean and the memory of the person being honored.
Scope of Plastic Pollution in the Ocean
Plastic pollution has become one of the most significant environmental challenges affecting the world’s oceans. Each year, millions of tons of plastic waste enter marine environments from a combination of land-based sources, shipping activities, and fishing industries.
Researchers estimate that approximately 8 million metric tons of plastic enter the ocean every year. Once in the water, plastic debris can travel long distances on ocean currents, eventually accumulating in large concentrations known as ocean garbage patches. One of the most well-known examples is the Great Pacific Garbage Patch, located in the North Pacific Ocean.
Unlike natural materials, most plastics do not biodegrade quickly. Instead, they gradually break down into smaller fragments known as microplastics, which are tiny plastic particles less than five millimeters in size. These particles can remain in the ocean for decades and are easily ingested by marine organisms.
Because of their size and persistence, microplastics have become widespread throughout marine ecosystems. They have been detected in ocean water, sediments, and in many species of fish and marine life.
Understanding the scale of plastic pollution highlights why protecting ocean environments has become an important global priority.
Environmental Impact of Ocean Plastic
Plastic pollution can have serious consequences for marine ecosystems. Many marine animals—including fish, seabirds, sea turtles, and marine mammals—encounter plastic debris in the ocean and may mistake it for food. When plastic is ingested, it can block digestive systems, reduce nutrient absorption, and weaken the animal’s ability to survive.
Sea turtles, for example, sometimes mistake floating plastic bags for jellyfish, one of their natural food sources. Ingesting plastic can lead to internal injury or starvation. Seabirds and fish may also consume small plastic fragments or microplastics, which can accumulate in their bodies over time.
Plastic debris can also entangle marine animals. Discarded fishing nets, plastic rings, and other debris may trap animals, restricting their movement and making it difficult for them to swim, hunt, or breathe. In some cases, entanglement can lead to severe injuries or death.
In addition to harming individual animals, plastic pollution can damage marine habitats. Coral reefs, which support a large portion of ocean biodiversity, are particularly vulnerable. Plastic debris can physically damage coral structures and increase the risk of disease, threatening these important ecosystems.
Because marine life and habitats are interconnected, the effects of plastic pollution can ripple throughout the entire ocean environment.
Human Health and Economic Impacts
Plastic pollution in the ocean does not only affect marine life—it can also impact human health and coastal economies. As plastics break down into smaller fragments known as microplastics, these particles can enter the marine food chain. Fish and other seafood species may ingest microplastics, which can then make their way into the human diet.
Researchers are still studying the long-term health effects of microplastic exposure in humans. Some studies suggest potential concerns related to inflammation, chemical exposure, and other health risks, though more research is needed to fully understand these impacts.
Plastic pollution also affects industries that depend on healthy oceans. Coastal tourism can decline when beaches and shorelines are polluted with plastic debris. Communities that rely on fishing may experience economic losses when marine ecosystems are damaged or fish populations decline.
In addition, governments and local communities often spend significant resources on cleanup efforts to remove plastic waste from beaches, harbors, and waterways. These costs can place additional financial pressure on coastal regions.
Protecting the health of the ocean is therefore not only an environmental issue, but also an economic and public health priority.
Solutions to Combat Ocean Plastic Pollution
Addressing plastic pollution in the ocean requires cooperation between individuals, businesses, and governments. While the problem is global in scale, meaningful progress can be made through a combination of responsible consumption, improved waste management, and supportive public policies.
One of the most effective ways to reduce plastic pollution is to limit the use of single-use plastics. Products such as disposable bags, bottles, and packaging often end up in waterways and eventually reach the ocean. Choosing reusable alternatives—such as cloth bags, refillable bottles, and durable containers—can significantly reduce the amount of plastic waste entering the environment.
Improving waste management systems is another critical step. Communities that invest in effective recycling programs, waste collection infrastructure, and public education can prevent large amounts of plastic from reaching rivers and coastal waters. Proper disposal and recycling of plastics helps keep these materials out of marine ecosystems.
Government policies also play an important role. Many regions have introduced measures such as restrictions on plastic bags, bans on certain single-use plastic items, and regulations that require manufacturers to take greater responsibility for packaging waste. These policies can help reduce the overall production and disposal of plastics.
Innovation and research are also contributing to potential solutions. Scientists and manufacturers are developing biodegradable materials, improved recycling technologies, and alternative packaging options that may help reduce the environmental impact of plastic products in the future.
Reducing ocean plastic pollution will require continued awareness and cooperation, but small changes at both individual and institutional levels can contribute to healthier oceans over time.
Protecting the Ocean During Ash Scattering
Families who choose ash scattering at sea often feel a deep connection to the ocean and want to ensure their memorial honors both their loved one and the environment. Responsible burial at sea practices help protect marine ecosystems while allowing families to hold meaningful ceremonies on the water.
Using biodegradable urns, natural flowers, and environmentally responsible materials helps minimize impact on the ocean. Federal environmental guidelines also require that cremated remains be scattered at least three nautical miles offshore, helping ensure that memorials take place in appropriate ocean waters.
To help protect marine life, we also encourage families to avoid releasing items that can become ocean debris. For example, balloons are not permitted on board, as balloons can travel long distances and eventually harm marine animals when they fall back into the ocean.
By making thoughtful choices, families can create a respectful memorial while also supporting the long-term health of the ocean.
Respecting the Ocean During Burial at Sea
Plastic pollution is a growing challenge for oceans around the world, affecting marine life, coastal communities, and the health of marine ecosystems. Greater awareness of this issue helps encourage responsible choices that protect the ocean for future generations.
For families who choose full body burial at sea or ash scattering at sea, simple decisions—such as using biodegradable materials and avoiding items that may become ocean debris—can help ensure that memorial ceremonies respect both the environment and the memory of the person being honored.
By making thoughtful choices, families can create a respectful memorial while also supporting the long-term health of the ocean. Families who would like to learn more about how burial at sea works can visit our burial at sea FAQ page for additional information.
At San Diego Burial at Sea, we are committed to conducting memorials with care, dignity, and respect for the ocean that surrounds us.
