Ocean Pollution's Economic Impact: A Costly Affair

Marine plastic pollution has far-reaching consequences for the economy, with an estimated cost to society of up to $2.5 trillion per year. The impact of plastic waste on the environment and human health is significant, with plastic pollution damaging food supplies and the air we breathe. The leading sources of plastic pollution include inadequate waste disposal, nonpoint source pollution from runoff, and point source pollution from oil spills or chemical releases. These sources contribute to the billions of pounds of trash and pollutants that enter the ocean each year, affecting marine life and human communities that depend on ocean-related industries. The economic costs are wide-ranging, including clean-up operations, reduced fishing catches, and declines in coastal tourism.

Marine pollution reduces economic opportunities in industries like tourism and fishing

Marine pollution poses a significant threat to economic opportunities in industries such as tourism and fishing. The presence of marine debris and plastic pollution can deter tourists from visiting beaches and coastal areas, leading to a decline in tourism revenue and local job losses.

In the United States, for example, marine debris has been shown to negatively impact the tourism and recreation sector, which is the largest employer in the ocean and Great Lakes economy. A study funded by the NOAA Marine Debris Program found that increasing the amount of marine debris on beaches led to a decrease in the number of days visitors spent at these locations, resulting in reduced tourism spending and a decrease in local employment opportunities. This is particularly detrimental to coastal communities that heavily rely on tourism for their livelihoods.

The issue of marine debris also extends beyond aesthetics and has practical implications for fishing and fisheries. Marine debris can interfere with active fishing gear, reduce commercial catches, and result in lost revenue for fishers. Lost or derelict fishing gear can damage sensitive habitats, create navigation hazards, and continue to catch species through "ghost fishing," further impacting the profitability of fishing operations.

Additionally, plastic pollution in the ocean poses a threat to marine life, including fish and charismatic" animals such as turtles and whales. The perceived threat of consuming plastic-infested seafood could harm fisheries and deter tourists, further exacerbating the economic losses.

The economic impact of marine pollution is not limited to direct losses in tourism and fishing but also includes the costs associated with cleanup efforts. Beach clean-up campaigns incur significant expenses, and failing to address marine pollution can result in higher costs for both local governments and beachgoers who may need to travel farther to find cleaner beaches.

Overall, marine pollution has far-reaching consequences, reducing economic opportunities and affecting the well-being and livelihoods of communities that depend on marine environments for their survival.

Marine debris can keep tourists away from beaches, reducing local jobs

Marine debris can be a significant deterrent for tourists considering a beach visit. The presence of debris negatively impacts the aesthetic appeal of beaches, creating an eyesore that may drive tourists away. This has a direct impact on the local economy, as a reduction in tourist numbers leads to decreased spending and a subsequent loss of local jobs.

The tourism and recreation sector is the largest employer in the ocean and Great Lakes economy in the United States. Marine debris on beaches can deter tourists from visiting and spending money in coastal communities, many of which are heavily reliant on tourism. This loss of revenue can have a ripple effect on the local economy, affecting businesses and residents alike.

Research supports this, with a study in coastal Alabama finding that doubling marine debris on beaches led to an estimated decrease of 1 million visitor days, resulting in a loss of $113 million in tourism spending and a reduction of nearly 2,200 jobs. Conversely, reducing marine debris can have a positive impact on tourism-related spending and employment. For example, the same study found that minimising marine debris on Ohio's beaches was estimated to generate an additional $217 million in tourism revenue and create over 3,700 jobs.

The impact of marine debris on tourism preferences is not limited to a specific region. A study in Orange County, California, revealed that beachgoers were willing to travel further and spend more to find a clean beach, free from debris. This resulted in losses of millions of dollars annually, and by reducing marine debris on beaches by just 25%, residents could save a significant amount of money during the summer months.

The issue of marine debris is not confined to a single source. While a portion of it can be attributed to ocean-based sources such as commercial fishing vessels and cargo ships, the majority originates from land-based activities, including litter from pedestrians and beachgoers, industrial discharges, and improper disposal of waste.

Marine debris can compete with fishing gear and reduce commercial catches

Marine debris, such as derelict fishing gear, can compete with active fishing gear and reduce commercial catches. Derelict fishing gear is lost or discarded gear that includes lines, nets, pots, traps, floats, and other equipment. Once in the ocean, this gear can continue to trap economically important species of fish, crustaceans, and other marine life, resulting in lost catch opportunities and financial losses for fishers.

For example, a study found that 3.3 million blue crabs are killed annually in derelict crab pots in the Chesapeake Bay, along with many other non-target animals. This leads to a substantial loss of revenue for fishers as they compete with the derelict gear for their catch. The removal of derelict fishing gear is, therefore, crucial to increasing gear efficiency, reducing costs for fishers, and boosting commercial landings.

The presence of marine debris on beaches also negatively impacts tourism, a significant contributor to the economies of coastal communities. Tourists may choose to avoid beaches littered with debris, opting for cleaner alternatives. This results in decreased tourism spending and a reduction in local jobs. Marine debris also incurs clean-up costs for local governments and volunteer organizations, further straining limited resources.

The economic losses due to marine debris are significant. A study estimated that reducing marine debris on beaches in Ohio by almost zero would result in an additional $217 million in tourism revenue and over 3,700 jobs. Similarly, removing less than 10% of derelict pots and traps from major crustacean fisheries globally could increase annual landings by $831 million.

The issue of derelict fishing gear is widespread, with debris accumulating in areas such as the Great Pacific Garbage Patch and the Papahānaumokuākea Marine National Monument in Hawaii. Addressing marine debris through clean-up efforts and promoting plastic reduction and recycling are essential to mitigating the economic impacts on fisheries and tourism-dependent communities.

Plastic pollution can threaten the cultural heritage and history of communities

Plastic pollution poses a significant threat to the cultural heritage and history of communities. The presence of plastic waste, which is now ubiquitous across ecosystems worldwide, can be seen as a "toxic heritage", with plastic waste undergoing a phase of plasticity before eventually fracturing into hazardous micro- and nano-plastics. This process poses a threat to the cultural heritage and history that has been preserved over time.

The degradation of plastic waste into microplastics can have detrimental impacts on human well-being. Certain animals, such as turtles and whales, hold cultural or emotional importance, and witnessing their suffering due to plastic pollution can negatively affect people's mental health. This can lead to decreased recreational activities, causing a range of physical and mental health costs.

The impact of plastic pollution on fisheries and aquaculture can also threaten cultural heritage. As fish ingest more plastic, the perceived threat of consuming seafood infested with plastic could harm fisheries and aquaculture industries, which are a source of livelihood for many communities. Additionally, the presence of plastic debris on beaches can deter tourists from visiting, further impacting the economy of coastal communities.

Communities that rely on marine environments for their livelihoods are particularly vulnerable to the economic and societal repercussions of plastic pollution. The marine environment holds immense cultural significance for these communities, and the pollution poses a direct threat to their cultural heritage and history. The transboundary nature of the problem is more significant for islands, as many are heavily dependent on tourism. A clean ocean is essential for the well-being, biodiversity, and livelihoods of these island communities.

Marine debris can damage sensitive habitats and create safety and navigation hazards

Marine debris can cause serious harm to sensitive habitats and create safety and navigation hazards, which can have a significant impact on the economy.

Damage to Sensitive Habitats

Marine debris can be found in various habitats, including nearshore wetlands, mangroves, coral reefs, seagrass meadows, sandy beaches, and oyster reefs. This waste can smother or crush sensitive plants and corals, reducing their access to light and oxygen, and hindering their growth and survival. For example, derelict fishing gear and abandoned vessels can smother and crush coral reefs, with the latter also releasing fuel, anti-fouling paints, and other chemicals that contaminate the surrounding water. Mangroves, which provide protection and stabilisation to coastlines, can be trapped with trash, derelict fishing gear, and abandoned vessels, blocking the movement of water and smothering mangrove seedlings. Marine debris can also alter the physical properties of sandy beaches, causing the sand to warm more slowly and impacting the wildlife that calls these beaches home.

Safety and Navigation Hazards

Marine debris, especially larger items like abandoned vessels, shipping containers, and derelict fishing gear, can pose significant safety and navigation hazards. These objects can be difficult to spot, especially if they are floating below the water's surface, and can damage vessels and put people's lives at risk. Derelict fishing gear, such as lines, nets, and traps, can wrap around propellers and rudders or tangle with active fishing gear, leading to costly vessel damage and potentially dangerous situations for those on board. Additionally, during natural disasters, high winds, heavy rains, and tidal surges can carry marine debris far out to sea, blocking navigational channels and making it challenging to reach people during emergencies.

The economic impact of marine debris is significant. Damage to sensitive habitats, such as coral reefs and mangroves, can affect industries like tourism and fishing that rely on these ecosystems. Additionally, the presence of marine debris can deter tourists, leading to decreased tourism revenues. The clean-up costs associated with removing marine debris from beaches and other affected areas can also be substantial.
