What You'll Learn
Plastic in the human food chain
Plastic in the ocean has a direct and deadly effect on wildlife. Marine animals suffer the most direct and damaging effects of ocean plastic pollution. Thousands of seabirds, sea turtles, seals, and other marine mammals die each year from ingesting plastic or getting entangled in it. Sea turtles, for example, can mistake floating plastic garbage for food, choke on it, and sustain internal injuries or die. It can also cause starvation by making them feel full. Research indicates that half of the sea turtles worldwide have ingested plastic.
Plastic in the ocean has entered the human food chain. Animals carry microplastics in their bodies, and when they are eaten, those microplastics are passed on to the consumer. This process is called "trophic transfer". Microplastics can move through the food chain because animals are eaten by other animals. For example, arrow worms consume plastic microfibers, and they are in turn eaten by animals higher up the food chain.
Microplastics have been found in human blood, placentas, and food and drinks, including tap water, beer, and salt. They enter the human body through ingestion (by food and water), inhalation (indoor and outdoor air), and skin contact (by personal care products, dust, and textiles).
The chemicals used in the production of plastic materials are known to be carcinogenic and can cause developmental, reproductive, neurological, and immune disorders. Microplastics can also carry other toxic chemicals and microorganisms, which can induce adverse health effects, including intestinal damage, immune problems, and neurotoxicity.
Plastic pollution in the ocean can also affect food safety and economic activities. It can contaminate seafood and, in turn, affect the income of those in the fisheries sector.

Impact on human health
Plastic pollution in the ocean has a detrimental impact on human health in several ways. Firstly, it poses a direct threat to human health through the ingestion of contaminated seafood. Plastic waste in the ocean acts as a magnet for persistent organic pollutants, which adhere to its surface. These pollutants include toxic chemicals such as per- and polyfluoroalkyl substances (PFAS), which are resistant to biodegradation and have been detected in drinking water sources. When fish ingest these plastic fragments, the pollutants can accumulate in their bodies and subsequently enter the human food chain. This has been evidenced by studies showing that fish in the North Pacific ingest substantial amounts of plastic each year, leading to intestinal injuries and death.
Secondly, plastic pollution contributes to biodiversity loss and ecosystem degradation, which indirectly affects human health and well-being. The disruption of natural ecosystems compromises conservation efforts and impacts key economic sectors such as agriculture, fisheries, and water safety. This, in turn, influences human livelihoods, food production capabilities, and social well-being.
Moreover, the chemicals used in the production of plastic materials are known to have harmful effects on human health. These chemicals have been linked to various disorders, including developmental, reproductive, neurological, and immune issues. Microplastics, which are tiny plastic particles, have been detected in human blood, placentas, and everyday consumables like tap water, beer, and salt. This indicates that humans are inadvertently consuming microplastics, potentially leading to adverse health consequences.
The impact of plastic pollution extends beyond the direct ingestion of contaminated seafood or microplastics. It also includes the broader ramifications on ecosystems and economies, ultimately influencing human health and quality of life. Addressing plastic pollution requires a systemic transformation towards a circular economy, phasing out harmful plastic production, and implementing strong national plans and compliance mechanisms.
In summary, the effects of plastic pollution in the ocean on human health are multifaceted and significant. They range from direct ingestion of contaminated seafood to the insidious presence of microplastics in our daily lives, compromising ecosystems, and impacting socio-economic factors that influence human health and well-being. Recognizing the magnitude of this global crisis is crucial to galvanizing collective efforts for change.

Economic impact
Plastic pollution in the ocean has far-reaching economic impacts, affecting countries, communities, and industries worldwide. Firstly, it disrupts trade systems and economies at a national level. Sectors such as small and medium-sized enterprises, the informal sector, tourism, fisheries, agriculture, and water safety experience income declines due to the negative perception and reality of plastic-infested environments. This is particularly true for coastal communities, which rely on the ocean's health and the attractions of marine life for tourism revenue. The presence of plastic pollution in these environments discourages visitors, reducing income for local businesses and the community at large.
Secondly, plastic pollution in the ocean affects fisheries and aquaculture industries. Fish are ingesting more plastic pollution, and research indicates that approximately 35% of fish in a 2008 Pacific Gyre study had ingested plastic pieces. The perceived threat of consuming seafood infested with plastic has the potential to harm the fishing industry, reducing income and affecting the livelihoods of those who depend on it. This is especially pertinent given that marine life is increasingly ingesting plastics coated with pollutants, which can be absorbed into their bodies and eventually passed on to humans through the food chain.
Thirdly, plastic pollution in the ocean impacts the provision of materials for agricultural use. As plastic breaks down into microplastics, these tiny particles can contaminate soil and water sources, affecting crop growth and reducing yields. This, in turn, can lead to economic losses for farmers and agricultural businesses, as well as contribute to food insecurity and increased prices for consumers.
Lastly, the economic burden of addressing plastic pollution and its consequences is significant. Cleanup operations and infrastructure development require public and private investment. While these efforts are essential, they also divert resources that could have been allocated elsewhere for economic development or community initiatives. Additionally, the transition to sustainable alternatives to plastic can be challenging, especially for impoverished communities, due to the higher initial costs of sustainable materials. However, it is important to note that a sustainable economy has the potential to create numerous jobs and generate substantial economic value.

Climate change contribution
Plastic pollution in the ocean has a detrimental impact on human health, food and water safety, economic activities, and contributes to climate change.
Plastic pollution in the ocean is not just an environmental concern but also a significant contributor to climate change. Firstly, plastics are predominantly made from fossil fuels, with 99% of plastics derived from this source. The production of plastics is closely linked to the fossil fuel industry, which is a major emitter of greenhouse gases. By 2050, it is estimated that 20% of our oil consumption will be directed towards plastic production. This shift in oil usage will impact our transition to cleaner energy sources and contribute to the accumulation of greenhouse gases in the atmosphere.
Secondly, the presence of plastic in the oceans can interfere with the ocean's ability to absorb and sequester carbon dioxide. The oceans play a crucial role in mitigating climate change by absorbing a significant portion of the carbon dioxide emitted by human activities. However, microplastics tend to concentrate on the surface of the ocean, disrupting the natural process of carbon absorption. This disruption will accelerate climate change, as highlighted by Dr. Warner: "The oceans have been taking up 30 to 50% of all of this carbon dioxide that we've emitted. So, if we disrupt the ability of the ocean to do this, it will just make climate change that much worse."
Additionally, the connection between plastic pollution and climate change is bidirectional. Climate change itself can worsen plastic pollution. Extreme weather events and flooding associated with climate change increase the risks of accidents and unauthorized pollution releases, leading to higher levels of plastic and chemical pollution entering our oceans.
Furthermore, plastic pollution and climate change share a common denominator in fossil fuels. The production and use of plastics contribute to the demand for fossil fuels, perpetuating the cycle of carbon emissions and climate change.
To effectively address the climate crisis, it is imperative to recognize plastic pollution as a contributing factor and take decisive steps to reduce plastic production and transition towards cleaner alternatives. This includes phasing out harmful subsidies, eliminating products and chemicals that harm the environment, and adopting strong national plans that align with the goals of international agreements, such as the Paris Climate Agreement.

Threat to biodiversity
Plastic pollution in the oceans is a pressing issue that poses a significant threat to biodiversity. It endangers marine life, disrupts ecosystems, and has far-reaching consequences for the environment and human well-being.
The presence of plastic in the oceans is a direct consequence of human activities, with pollution originating primarily from land runoff, including urban and stormwater runoff, littering, industrial activities, and agricultural practices. The durability of plastic materials means that once they enter the marine environment, they persist for long periods, causing ongoing harm.
One of the most devastating impacts of plastic pollution on biodiversity is the direct harm it causes to marine organisms. From fish to turtles, seals, crustaceans, seabirds, microorganisms, and many other forms of life, plastic ingestion and entanglement have been documented. Endangered species are particularly vulnerable, with entanglement in fishing gear listed as the second leading cause of death for Mediterranean monk seals. Sea turtles, for instance, mistake floating plastic garbage for food, leading to choking, internal injuries, or starvation as plastic reduces the storage volume of their stomachs. Research indicates that half of the sea turtles worldwide have ingested plastic, and it is estimated that 60% of all seabird species have eaten plastic, with a projected increase to 99% by 2050.
The impact of plastic pollution extends beyond the immediate harm to individual organisms. It also disrupts marine ecosystems and food chains. Plastic debris acts as a transport mechanism for invasive species and pollutants, which can be absorbed by marine life that ingests plastic. This contamination of the food chain ultimately affects human consumers as well. Furthermore, plastic pollution can alter habitats and natural processes, reducing ecosystems' ability to adapt to climate change and impacting millions of people's livelihoods, food production, and social well-being.
The scale of the problem is immense, with plastic pollution affecting all five of the Earth's major ocean gyres and accumulating in swirling convergences that make up about 40% of the world's ocean surfaces. While people in high-income countries consume the most plastic, effective waste management systems in these countries help keep plastic out of the natural environment. The challenge is more significant in middle-income countries, where plastic consumption is increasing, and inadequate waste management systems struggle to keep up with the rising consumption.
To address the threat to biodiversity posed by plastic pollution, a systemic transformation is necessary. This includes ambitious reductions in plastic production, phasing out harmful products and chemicals, improving waste management practices, and implementing legally binding control measures that prioritize the protection and restoration of biodiversity.
