The Plastic Pollution Of Henderson Island

Henderson Island, an uninhabited island in the South Pacific Ocean, has the highest density of plastic pollution in the world. In 2019, an expedition team to the island collected nearly 55,000 pieces of trash, concluding that nearly 18 tons of plastic had piled up, giving Henderson the highest density of plastic in the world. The plastic waste, carried by the powerful South Pacific Gyre, poses a danger to the island's wildlife, including birds, crabs, and sea life.

Plastic pollution solutions

Henderson Island, a tiny island in the South Pacific Ocean between Australia and Chile, is one of the most remote places on Earth. It is uninhabited and supports only a limited number of plant and animal species. However, despite its isolation, Henderson Island has the world's highest density of plastic pollution. An estimated 18 tons of plastic waste have washed ashore, with an accumulation of 38 million pieces, arriving at a rate of about 3,500 pieces per day. The plastic waste on Henderson Island is a stark reminder of the global plastic pollution crisis and the urgent need for solutions. Here are some measures that can be implemented to address plastic pollution:

Individual Actions

Individuals can make a significant impact by changing their daily habits and reducing their plastic consumption. This includes refusing single-use plastics, such as plastic bags, straws, and disposable water bottles, and opting for reusable alternatives instead. Carrying a reusable water bottle, for example, saves money and reduces plastic waste. It is also important to avoid products with microplastics, which are tiny plastic particles found in some beauty and cosmetic products. These microplastics can slip through water treatment plants and are often ingested by marine animals. Choosing products with natural exfoliants, like oatmeal or salt, is a more environmentally friendly option.

Proper Waste Disposal and Recycling

Proper waste disposal and recycling are crucial in reducing plastic pollution. Individuals can ensure they dispose of plastic waste responsibly and recycle whenever possible. However, it is important to note that recycling alone is not enough. The complex recycling process can be inefficient, and not all plastics are recyclable. Therefore, it is essential to prioritize reducing plastic consumption and supporting initiatives that promote sustainable alternatives.

Support Non-Profit Organizations

There are many non-profit organizations dedicated to combating plastic pollution, such as the Oceanic Society, Plastic Pollution Coalition, 5 Gyres, Algalita, and the Plastic Soup Foundation. These organizations rely on donations and support from individuals to continue their important work. By donating or volunteering with these organizations, individuals can actively contribute to finding solutions and raising awareness about plastic pollution.

Advocate for Legislation

Addressing plastic pollution requires systemic change, and individuals can play a role by advocating for legislation that targets plastic production and waste management. Supporting initiatives like the 2021 Break Free From Plastic Pollution Act in the United States or international efforts like the global plastics treaty are essential. These legislative actions aim to hold plastic producers and distributors accountable for their products' entire lifecycles, reducing the environmental impact of plastic pollution.

Innovative Repurposing

Innovative solutions, such as the process of turning plastic waste into low-cost housing material, offer promising alternatives to traditional recycling methods. For example, the Center for Regenerative Design and Collaboration in Costa Rica can transform non-recyclable plastic into aggregate, which is then added to concrete. This approach not only reduces plastic waste but also creates economic opportunities and addresses housing needs.

The plastic pollution crisis on Henderson Island serves as a stark reminder of the far-reaching consequences of our plastic consumption. By implementing these solutions and working together globally, we can make a significant impact in reducing plastic pollution and protecting our environment for future generations.

Impact on wildlife

Henderson Island, a raised coral atoll in the South Pacific Gyre, is one of the most remote places on Earth. The island is uninhabited, but its beaches are home to the world's highest density of trash, with an estimated 18 tons of plastic waste. This plastic pollution has had a significant impact on the local wildlife.

One of the most affected species is the hermit crab. Crabs on the island have been observed using plastic containers as homes, only to become trapped and starve to death in the hot sun. The decaying corpses of these crabs then attract other crabs, leading to further fatalities. In addition, crabs and other marine life may be exposed to harmful chemicals as the plastics they live in or ingest break down.

Sea birds are also heavily impacted by the plastic pollution on Henderson Island. Single-use plastics have been found in the stomachs of dead seabirds, and nesting birds may be exposed to harmful chemicals leached from the plastics they use as nesting materials. In addition, the plastic pollution on the island attracts other wildlife, such as turtles searching for nesting sites, putting them at risk of entanglement or ingestion of plastic debris.

The plastic pollution on Henderson Island also has broader ecological impacts. The island is home to a unique ecosystem, including several endemic plant and animal species. The plastic debris, which can break down into microplastics and nanoplastics, can be ingested by marine life and enter the food chain, threatening the delicate balance of this isolated ecosystem.

While the full extent of the impact of plastic pollution on Henderson Island's wildlife is still unknown, it serves as a stark reminder of the need to reduce plastic waste and transition to a more sustainable, circular economy. Efforts by private groups and innovative repurposing initiatives, such as turning plastic waste into low-cost housing materials, offer some hope for mitigating the effects of plastic pollution on this fragile ecosystem.

Plastic's origin

Henderson Island is a raised coral atoll located in the South Pacific Ocean, around 193 km from Pitcairn Island. It is one of the last two raised coral atolls in the world whose ecosystems remain relatively untouched by human contact. The island is uninhabited and is known for its pristine beaches and diverse wildlife, including land birds, plants, and a large colony of seabirds.

However, despite its remote location, Henderson Island has become a dumping ground for plastic pollution. The island has the unfortunate distinction of having the world's highest density of plastic pollution, with an estimated 18 tons of plastic waste washing ashore over the years. The plastic pollution on Henderson Island originates from various parts of the world, including South America, Russia, the United States, Europe, Japan, China, and even specific countries like Japan, Scotland, Puerto Rico, the Netherlands, and the United States.

The primary source of plastic waste on Henderson Island is the South Pacific Gyre, a powerful ocean current that acts like a conveyor belt, carrying plastic trash from across the globe and depositing it on the island's shores. The isolation of the island, while protecting it from human intrusion, has not been able to shield it from the influx of plastic pollution. The plastic waste consists of a variety of items, including fishing nets and floats, water bottles, bottle caps, helmets, laundry baskets, toilet seats, razors, and shoe laces.

The impact of this plastic pollution is devastating for the local wildlife. Single-use plastics have been found in the stomachs of dead seabirds and whales, and other marine creatures become entangled and trapped, leading to their deaths. The issue of plastic pollution on Henderson Island has garnered international attention, with various organizations conducting expeditions to the island to study and address the problem. Efforts have been made to clean up the beaches, and there is a focus on finding innovative solutions, such as repurposing plastic waste into low-cost housing material.

The plastic pollution on Henderson Island serves as a stark reminder of the excessive use of single-use plastics and the need for a circular economy to address this global issue. It highlights the importance of raising awareness about the environmental impact of plastic pollution and the necessity of changing how consumers use and dispose of plastic products.

Beach clean-up efforts

Henderson Island, a tiny, uninhabited island in the South Pacific Ocean, has the highest density of plastic pollution in the world. The island is extremely remote, located roughly 5,000 km from the nearest continent, South America, and 3,200 km from the nearest inhabited island, Pitcairn Island. Despite its isolation, Henderson Island is inundated with plastic waste, with an estimated 18 tons of plastic waste piling up on its beaches. The plastic pollution on Henderson Island is a stark reminder of the excessive use of single-use plastics and their detrimental impact on the environment.

In 2019, a group of scientists, journalists, filmmakers, and artists, including PERC enviropreneur Brett Howell, embarked on an expedition to Henderson Island to address the plastic pollution crisis. The team's efforts focused on two main objectives: cleaning up the island and collecting valuable scientific data to address the broader issue of plastic pollution. The density of waste on the beach was staggering, taking a full-time, four-person team an entire day to clean a mere 300-foot stretch of sand. The waste included items attributable to the global fishing industry, such as buoys and fish aggregation devices, as well as everyday household items like laundry baskets, razors, and toothbrushes.

The 2019 expedition successfully cleared 100% of the beach down to bottle cap-sized materials, amounting to approximately 14,000 pounds of trash. The collected waste was securely stored on Henderson Island, awaiting further solutions for recycling and repurposing. The cleanup efforts also yielded significant scientific data, contributing to a deeper understanding of plastic pollution's impact on remote beach ecosystems. This data has since been shared through various publications and media outlets, raising awareness of the plastic pollution crisis.

The Henderson Island Plastic Pollution Expedition continues to make strides, with a 2024 expedition building upon the previous work. The expedition team has collaborated with various organizations, such as the Howell Conservation Fund, Exponent Philanthropy, and Charities Aid Foundation of America, to secure funding and support for their efforts. The ultimate goal is not just to clean up Henderson Island but to address the root cause of plastic pollution and pioneer innovative solutions to environmental issues.

One potential solution proposed by Howell is to repurpose the collected plastic into low-cost housing material. The non-recyclable plastic can be heated and crushed into lightweight aggregate, which can then be added to concrete. This process not only creates useful material but also generates jobs and contributes to sustainable development. By addressing the issue of plastic pollution through circular economy solutions, the expedition team hopes to curb the growing problem of plastic waste in our oceans and protect vulnerable ecosystems worldwide.

The island's history

Henderson Island is an uninhabited island in the South Pacific Ocean, located about halfway between Peru and New Zealand. It is one of four islands that make up the Pitcairn Islands, along with Pitcairn, Oeno, and Ducie. The island was first settled by Polynesians, possibly as early as 800 AD, and there is evidence that it was continuously occupied for a 600-year period before being abandoned by the 1600s. The reasons for the disappearance of the original inhabitants are uncertain, but it is believed that it may have been due to resource exhaustion and the disappearance of the Polynesians on nearby Pitcairn Island, on whom the people of Henderson relied for resources and tools.

In 1902, Henderson Island was annexed to the Pitcairn Islands colony, which is now a British Overseas Territory. The island is one of the last two raised coral atolls in the world whose ecosystems remain relatively unaffected by human contact, and in the 1980s, it was designated a UNESCO World Heritage Site due to its pristine state.

However, in recent years, Henderson Island has gained attention for a different reason: its plastic pollution. In 2015, an expedition to the island revealed that its once pristine beaches were covered in an alarming amount of plastic debris. The team, which included scientists Jennifer Lavers and Alex Bond, found an estimated 38 million pieces of plastic, with a density of 672 items per square meter. This gave Henderson Island the highest density of plastic debris recorded anywhere in the world at the time. Much of the plastic pollution on the island is believed to come from industry and passing ships, with items originating from various countries, including Japan, the United States, Europe, and South America.

Since the 2015 expedition, there have been ongoing efforts to address the plastic pollution on Henderson Island. In 2019, a team of scientists, conservationists, and journalists from New Zealand spent two weeks collecting six tons of rubbish. However, due to weather conditions, the collected rubbish had to be left on the beach, with only some samples removed for research. Another expedition in 2024, led by Plastic Odyssey, successfully cleaned up the beach using innovative low-tech solutions, and the collected plastic waste was recycled and transformed into street furniture for the neighbouring island of Pitcairn.
