What You'll Learn
Beach pollution impacts over 800 wildlife species globally
Beach pollution has had a detrimental impact on over 800 wildlife species globally. The majority of pollutants that end up on beaches and in the ocean come from human activities, such as land-based sources and activities along coastlines and far inland.
One of the biggest sources of beach pollution is nonpoint source pollution, which occurs as a result of runoff from sources like septic tanks, farms, and vehicles. Pollution that comes from a single source, like an oil or chemical spill, is known as point source pollution. These sources of pollution can have large impacts on wildlife and the environment.
Plastics are a significant contributor to beach pollution, with billions of pounds of plastic found in the ocean, making up about 40% of the world's ocean surfaces. Plastic pollution has a direct and deadly effect on wildlife, with thousands of seabirds, sea turtles, seals, and other marine mammals killed each year after ingesting plastic or getting entangled in it. Research indicates that half of the sea turtles worldwide have ingested plastic, choking, sustaining internal injuries, or starving by thinking they are full. It is estimated that 60% of all seabird species have eaten plastic, with that number predicted to increase to 99% by 2050.
In addition to plastics, beach pollution also includes other debris such as derelict fishing gear, abandoned vessels, and litter. Heavy metals and other contaminants can accumulate in seafood, making it harmful for both wildlife and humans to consume. Microplastics, smaller than 5 mm, can be ingested by fish and other species that filter their food from the water. This has affected over one-third of the shellfish-growing waters in the United States, posing a threat to human health and wildlife.
The impact of beach pollution on wildlife is not limited to marine species. Pollution from sources such as agricultural fertilizers and greenhouse gas emissions has had strong negative effects on freshwater habitats, soil, and the atmosphere, which many species depend on. Contaminants, excess light, and noise directly or indirectly threaten many species, including birds, whales, fish, and turtles.
To address the impact of beach pollution on wildlife, urgent action is needed to reduce plastic pollution, improve waste management practices, and regulate the discharge of pollutants into the ocean and coastal environments. By protecting and preserving the sensitive beach environment, we can safeguard the plants and animals that depend on it and ensure a sustainable future for all.

Billions of pounds of trash and other pollutants enter the ocean annually
Plastic pollution is a significant contributor to the billions of pounds of trash and other pollutants that enter the ocean each year. Plastic waste can come from thousands of sources worldwide, and improper waste management in many countries has made it a global problem. Plastic pollution not only damages the environment but also poses risks to human health and economies. It is estimated that plastic pollution costs governments, tourism, and fisheries up to $19 billion annually.
The impact of plastic pollution on marine life is devastating. Worldwide, hundreds of marine species have been negatively affected by plastic and other debris, which they can ingest or become entangled in. Seabirds, sea turtles, seals, and other marine mammals are particularly vulnerable, with over 100,000 dying each year from ingesting plastic or getting entangled in it. Plastic pollution has also been shown to alter the temperature of the sand where sea turtles typically incubate their eggs, impacting their reproduction rates.
Beach pollution from litter, sewage, plastic, and other pollutants poses a serious health risk to humans who come into contact with contaminated water or sand. It can also limit the economic and recreational value of beaches, reducing property values and inhibiting economic growth in coastal communities. Closed beaches due to pollution can adversely affect local businesses and the tourism industry in the region.
Addressing the billions of pounds of trash and other pollutants that enter the ocean each year requires a global response. Understanding the devastating effects of pollution on beaches and the ocean is the first step towards finding solutions. Policy enforcement and change are essential in tackling this issue on a national level.

Sewage overflows are a major cause of beach closures
Beach pollution is any harmful substance that contaminates coastal environments, including lakes and oceans. It can include plastic, trash, litter, sewage, pesticides, and oil. Sewage overflows are a major contributor to beach pollution and are a significant cause of beach closures.
Sewage overflows can occur when there is a blockage or collapse in the sewer system, causing untreated sewage to spill into nearby waterways and, ultimately, onto beaches. For example, in 2022, a pipe collapse in Los Angeles County resulted in the release of 8.5 million gallons of untreated sewage into the Dominguez Channel, forcing the closure of at least five beaches. Similarly, in 2023, a blockage in a sewer in Downey, California, caused an overflow of 250,000 gallons of sewage into the Los Angeles River, leading to the closure of beaches in Long Beach.
Untreated sewage contains bacteria and nitrogen pollution that can contaminate recreational waters, posing a significant risk to human health. Fecal bacteria in sewage can cause gastrointestinal illnesses and infections of the eyes, ears, nose, and throat. As a result, communities are often forced to close local beaches to prevent residents from coming into contact with contaminated water.
The impact of sewage overflows and beach closures extends beyond public health concerns. Beach closures can have negative economic consequences for coastal communities, affecting revenue from admission fees, concession stands, restaurants, and tourism businesses. Additionally, beach pollution can destroy unique beach habitats needed by animals and plants, impacting the ecosystem and biodiversity.
To reduce the frequency of beach closures due to sewage overflows, it is crucial to invest in upgrading and modernizing wastewater infrastructure. This includes fixing combined sewer overflows (CSOs) and sanitary sewer overflows (SSOs) to prevent the discharge of raw sewage into coastal waters. By addressing these issues, we can protect public health, support local economies, and preserve the delicate balance of coastal ecosystems for future generations.

Climate change increases beach erosion and pollution
Climate change poses a significant threat to beaches, increasing erosion and pollution and negatively impacting the environment, local economies, and communities.
Sea level rise, a consequence of climate change, is a key factor contributing to the heightened vulnerability of beaches to erosion. As sea levels continue to rise, beaches face the risk of inundation, resulting in the loss of valuable coastal land. This loss directly affects the surrounding environment and communities, threatening the habitats of diverse species, including sea animals, birds, and other wildlife. Additionally, coastal wetlands, which play a crucial role in providing habitats and mitigating storm impacts, are also at risk, further exacerbating the impacts of climate change.
The combination of rising sea levels and more intense and frequent storms creates optimal conditions for severe beach erosion. Climate change intensifies the frequency and strength of storms, leading to increased coastal erosion. The impact of storms on beaches is particularly damaging when high tides and strong waves converge, causing extensive wear and tear on rocks, soils, and sands along the coast.
Moreover, climate change contributes to beach pollution, which has far-reaching consequences. Pollution of coastal environments by plastic, trash, litter, sewage, pesticides, and oil restricts the use of beaches for economic, recreational, and aesthetic purposes. It degrades and destroys unique habitats, poses health risks to humans, reduces property values, and hinders economic growth. Beach pollution also severely impacts marine life, with over 800 species affected worldwide. Seabirds, sea turtles, seals, and other marine mammals suffer from ingestion of plastic or entanglement, leading to injuries, starvation, and death.
To address the challenges of beach erosion and pollution exacerbated by climate change, communities are exploring various solutions. Nature-based approaches, such as living shorelines, green spaces, sand dunes, and oyster reefs, are being utilized to mitigate the impacts of storm surges, coastal flooding, and erosion. These natural solutions enhance the resilience of coastlines while preserving the natural movement of sand and water currents. Additionally, communities are encouraged to learn about beach health and participate in cleanup efforts to protect beaches and the surrounding ecosystems.
In summary, climate change intensifies beach erosion through rising sea levels and more frequent and intense storms. It also contributes to beach pollution, which has adverse effects on the environment, local economies, and communities. Addressing these challenges requires a combination of nature-based solutions, community engagement, and proactive measures to protect and restore the sensitive beach environment.

Beach pollution negatively impacts human health
Beach pollution is any harmful substance that contaminates coastal environments, including lakes and oceans. It can include plastic, trash, litter, sewage, pesticides, oil, and heavy metals. These pollutants can have significant negative impacts on human health, and it is important to understand these effects to address the problem effectively.
One of the primary ways beach pollution affects human health is through the ingestion of contaminated seafood. Heavy metals and other contaminants can accumulate in seafood, making it unsafe for human consumption. For example, microplastics can be ingested by fish and other marine species, which can then be consumed by humans. This can lead to the presence of harmful substances in the human body, potentially causing various health issues.
Beach pollution also contributes to the destruction of marine life and ecosystems. It is estimated that beach pollution impacts over 800 wildlife species globally. Seabirds, sea turtles, seals, and other marine mammals often ingest plastic or become entangled in garbage, leading to choking, internal injuries, or starvation. This disruption in the marine food chain can have indirect effects on human health. As humans consume seafood, the ingested plastic and other pollutants can move up the food chain, eventually reaching seafood-eating humans.
Additionally, beach pollution can lead to the closure of coastal areas, impacting local economies and communities. Beaches are important for economic activities, tourism, and recreational purposes. However, pollution can make beaches unsafe for human use, leading to closures to protect public health. For instance, in 2013, an NRDC report found that beaches in the United States experienced over 20,000 closings due to pollution, primarily related to near-shore bacteria levels that violated public health standards. These closures not only disrupt the enjoyment of beachgoers but also adversely affect local businesses and the tourism industry in the region.
Furthermore, beach pollution can have indirect health impacts on humans through the destruction of habitats and ecosystems. For example, harmful algae blooms (HABs) consume oxygen when they die and decompose, creating "dead zones" with little to no oxygen. These dead zones can kill off feeding sources for larger aquatic animals and destroy habitats, disrupting the balance of marine ecosystems. The loss of biodiversity and the accumulation of pollutants in the food chain can have long-term consequences for human health, as the quality and safety of seafood sources are compromised.
To address beach pollution and mitigate its negative impacts on human health, it is essential to implement proper waste management practices and reduce the use of single-use plastics and other harmful substances. Public education and policy enforcement are crucial steps towards creating a sustainable future for both marine life and human well-being.
