Health Risks of Microplastics and Plastic in Humans

Science is only beginning to understand the long-term effects of plastic on human health, yet the evidence so far is alarming. Microplastics have been found in the air we breathe, the food we eat1, and even in our organs and blood2. From production to disposal, our constant exposure and intake of plastic threaten our well-being.

Microplastics: Everywhere Even Inside Us

Microplastics are tiny plastic particles that result from the breakdown of larger plastic items or are manufactured as small pellets for industrial use. These particles have infiltrated almost every aspect of our environment:

There are more chemicals in plastic than previously thought. Plastics contain over 16,000 chemicals, many of which remain untested and may be toxic to human health. At least 4,200 (or 26%) of these are highly hazardous to human and environmental health.3

Scientists have found microplastics in human stools4, demonstrating how these particles are ingested and excreted by our bodies. Even more concerning is the discovery of microplastics in human lungs5, blood6, placentas, and breast milk7. This suggests that exposure to microplastics begins at a very early stage of development, potentially affecting health from the womb onward.

Inhalation and Ingestion of plastic:

Microplastics have been detected in the air we breathe and the food we eat 1. Research indicates that over 90 percent of samples of commercially available food-grade table salt from global brands contain microplastics 8. This widespread contamination highlights how pervasive microplastics and plastic in humans are becoming.

Plastic Food Contamination:

Microplastics have been found in a variety of commercially available foods, including seafood (such as fish, lobster, mussels, and clams)9. This contamination raises significant concerns about the potential health impacts of ingesting microplastics through our diet. The amount of microplastics a person might consume in food is difficult to quantify, but the implications for health are troubling.

The Hidden Dangers of Plastic Chemicals

Plastics contain over 16,000 chemicals, many of which remain untested and may be toxic to human health. At least 4,200 of these chemicals (or 26%) are highly hazardous to human and environmental health. The presence of these chemicals in everyday plastic products means that we are constantly exposed to potentially harmful substances.10


The presence of microplastics and plastic in humans is a clear indication of the pervasive nature of plastic pollution. While much remains to be understood about the long-term health effects of microplastics, the evidence so far underscores the urgent need for action.

A global threat needs a global response. Please help support the creation of a global plastics treaty by signing our petition today- before our planet chokes to death. Help end plastic pollution at the source and protect the health of future generations.

‘Step up and lead’: All eyes on Australia as it takes the reins of UN COP31 climate negotiations

Published

on

ANTALYA, Türkiye, Saturday 7 November 2026 — As leaders and delegates gather for the UN COP31 climate summit, Greenpeace Australia Pacific is calling on the Australian government in its role as President of Negotiations to ensure the just transition away from fossil fuels is central to negotiations, rigorously defend the 1.5°C temperature goal, and significantly scale up climate finance commitments.

This year’s climate talks take place amidst a deepening global energy shock, and grim reports that the world will barrel past the 1.5°C temperature goal. They also follow a deadly summer of extreme weather disasters that swept the northern hemisphere, with fears that a severe El Niño will see similar dangerous impacts in Australia.

But recent election wins by progressive candidates in the United States and Brazil are set to breathe energy and optimism into the negotiations as people around the world, bearing the brunt of soaring cost of living and climate disasters, shun regressive and divisive politics.

Speaking from Antalya, Dr Simon Bradshaw, COP31 Lead at Greenpeace Australia Pacific, said: “The world is in a moment of flux. We know it is in moments of huge upheaval that era-defining progress can happen — but only when countries step up and lead.

“As Australia takes control of COP31 Negotiations, we have an opportunity and responsibility to shepherd global climate cooperation through this moment of interlocking crises. That means backing Pacific leadership and priorities, and leading by example at home to end fossil fuels and deliver new, multi-year climate finance commitments.

“As a major coal and gas exporter, Australia plays an outsized role in fuelling the climate crisis, and has approved 38 new, extended and expanded fossil fuel projects since first elected in 2022. More than half the world’s coal export project pipeline is in Australia, and the Albanese Government is poised to make decisions on massive new gas projects. Australia must reckon with this reality.

“Domestically, we have made significant strides on ramping up renewables and the global ‘35 by 35’ electrification goal is welcome and necessary. But electrification must end fossil fuel dependence, not be an end in itself — its ultimate success depends on ensuring electricity comes from renewable sources that displace fossil fuels and align with a 1.5°C pathway.

“In Türkiye, the Australian government can rise to the occasion and show what true climate leadership looks like, but we can not move the world towards a clean energy future while expanding the industry we need to leave behind.”

Speaking from Antalya, Shiva Gounden, Head of Pacific at Greenpeace Australia Pacific, said: “As leaders meet in Türkiye amidst warnings that we will pass the 1.5°C threshold, the stakes have never been higher. Every heatwave, every flood, every storm is being unleashed on communities with the deadly force of accumulated emissions and gives a warning of what is to come.

“In Antalya, the COP31 Presidency must respond to the accelerating climate crisis and defend the 1.5°C goal based on the law and the science. 1.5°C is a non-negotiable survival line for Pacific communities and climate-vulnerable nations facing rising seas, extreme weather disasters, food insecurity and soaring economic costs. It is a fundamental component of the Paris Agreement and enshrined as a binding legal benchmark by the world’s highest court, the International Court of Justice.

“Australia must arrive at COP31 with more than meaningless speeches. The Pacific and the world need concrete dates, credible plans to deliver roadmaps away from fossil fuels built on the best available science, and a commitment to put people, energy security and the planet ahead of fossil fuel interests.

“We need real action to advance multilateral climate cooperation, ensure the just transition away from fossil fuels is high on the agenda, and back longstanding Pacific priorities — including keeping 1.5°C alive and significantly scaling-up climate finance.”

‘Blue COP31’ set to spotlight need for ocean protections amid record heat

Published

on

As an extreme El Niño breaks marine temperature records, COP31 is set to boost the profile of the ocean’s role in solving climate change, but finance and clear conservation measures will be needed for it to move the needle, experts said.

The Turkish presidency has announced plans for an Antalya Ocean Declaration that recognises the centrality of the global ocean – the world’s largest carbon sink – in regulating the climate and minimising the now unavoidable overshoot of global temperatures above 1.5C over pre-industrial levels.

Meanwhile, as part of the formal UN negotiations, Australia has announced plans to land a cover decision in Antalya, which, according to veteran former US negotiator Sue Biniaz, would be the only section of the formal negotiations where the role of oceans could be included.

She added that an outcome at COP31 seems likely, given the initiative from both presidencies and a push from over 100 countries – including Brazil, the EU and the African Group of countries – calling for the UN negotiations to deliver a plan for implementing ocean measures.

Governments will arrive in Antalya with a “super El Niño” adding stress to marine ecosystems and expected to continue to intensify until December 2026, with parts of the Pacific averaging almost 30C (86F) – over 3C more than normal – in October, according to monthly EU sea temperature data.

    Needs for ocean conservation and funding

    While elevating the ocean agenda is “critical”, it must lead to funding for ocean conservation and a clear plan for reaching the global target – set at UN biodiversity talks in 2022 – of protecting 30% of the global ocean by 2030, said Pradeep Singh, senior ocean governance expert at Oceano Azul Foundation.

    The ocean is precisely where governments are farthest off track from meeting this target – informally known as the 30×30 goal. Even if countries meet all their nature conservation plans, only about 12% of the global ocean would be protected, the UN says.

    “Acknowledgment of marine protected areas and the 30×30 target as climate infrastructures will certainly boost efforts and funding for science and management,” Singh told Climate Home News.

    Shamini Selvaratnam, director of international climate and clean energy at Ocean Conservancy, said an ocean commitment that makes a difference in coastal communities “takes funding, local capacity and support that countries can actually access”.

    An analysis by climate think tank Zero Carbon Analytics shows that investment in the blue economy – through activities like sustainable fisheries or cleaner shipping – is only at about 2% of the needs, which are estimated at $550 billion per year.

    Following-through on commitments

    Selvaratnam added that countries must also establish mechanisms to follow through on these measures, which currently only exists in the form of a non-binding dialogue that is not expected to produce any negotiated agreements.

    She said that countries at COP31 must find ways for their ocean commitments to inform the next global stocktake, the UN’s five-yearly review of progress on climate action. Some countries – including African countries, Latin American nations, small island states and the European Union – have backed a process that culminates in the next global stocktake.

    At climate negotiations, countries are not mandated to include ocean conservation measures in their climate plans. But a group of countries led by France and Brazil is pushing them to do so voluntarily through an initiative called Blue NDC Challenge. Seventeen countries have joined the initiative so far.

    In its list of COP31 priorities, the EU has called for the “critical role” of oceans to be recognised, but falls short of calling for any specific actions to feature marine action more prominently in climate plans.

    As part of their demands, ocean campaign groups have called for the establishment of an “Antalya Ocean Compact”, a platform where countries can coordinate efforts across different environmental treaties, including the UN climate, biodiversity and high seas negotiations.

    Ultimately, Selvaratnam said a strong deal “must accelerate emissions cuts, clean energy, and a transition away from fossil fuels, including offshore oil and gas”.

    Ilana Seid, chair of the AOSIS group of small island states and permanent representative of Palau to the UN, said during a press briefing last week that “meaningful progress” on emissions reduction is “the best way” to alleviate stress on the ocean.

    Nepal seeks stronger recognition of mountain issues in UN climate process

    Published

    on

    In the wake of its recent glacial flooding disaster, Nepal and the kingdom of Bhutan have proposed a new agenda item on mountains and climate change for the COP31 summit which opens on Monday in the Turkish city of Antalya.

    In a submission addressed to the COP31 presidency and the head of the UN climate secretariat (UNFCCC), Nepal said the agenda item, entitled “1.5°C Warming in Mountains”, is an effort to strengthen the response of the international community to the climate risks facing the world’s mountain regions.

    The item proposes that mountain issues should become a regular part of the formal UN climate change process, with a focus on scientific assessment of the risks associated with warming overshooting 1.5C, an annual high-level dialogue, a dedicated work programme and improved access to climate finance.

    Maheshwar Dhakal, chief of the climate change management division of Nepal’s Ministry of Agriculture, Forests and Environment, told Climate Home News that Himalayan countries face similar problems such as collapsing glaciers and flooding from glacial lakes. 

    “We are trying to bring all Himalayan countries together under this agenda item,” he said.

    COP31 Briefing: What to expect from the Antalya climate summit?

    At this year’s UN General Assembly, Nepal’s Prime Minister Balendra Shah called for strong global action to ensure climate justice and proposed creating a Himalayan Climate Resilience Mechanism led by India, China and Nepal. It would share satellite data, monitor glacial slopes and lakes, strengthen early warning systems and coordinate cross-border disaster response.

    Nepal has experienced significant infrastructure losses and human casualties from flooding every year since 2020. In late August, the collapse of a glacial slope on the border with Tibet caused a torrent of water and debris to course down the Bhote Koshi River, leaving more than 6,000 people dead or missing.

    According to a government needs assessment, the disaster caused an estimated $2.7 billion in physical damage and economic losses, while around $4.8 billion will be required for recovery and reconstruction.

    More research needed on threats

    Although high mountain regions are known to be fragile ecosystems, especially as global warming accelerates glacier melt, the extent of their vulnerability is still not fully understood. When the devastating Bhote Koshi floods hit, it opened the eyes of the world to the risks.

    Dhakal said the Bhote Koshi floods “have proved the impacts of climate change in the Himalayan region”, which were linked to rising temperatures by scientists with the World Weather Attribution group. “Therefore, Nepal wants scientific studies, research and political discussions on mountain climate risks to receive greater attention at international climate conferences,” he added.

    Nepal has been making efforts on this front since 2009, when it held a cabinet meeting at Kalapatthar near Mount Everest. Since COP28 in Dubai, Nepal has organised high-level events and dialogues on mountain issues at COPs and is co-hosting one at COP31 with Bhutan, Pakistan, Kyrgyzstan and Tajikistan.

    Dhakal said the dialogues held so far have raised awareness, but mountain concerns must become part of the formal UN climate process to unlock climate finance and technical support that can bolster countries’ capacity to tackle climate threats.

    If specific indicators and priorities are developed for mountain regions, vulnerable developing countries like Nepal would have better access to finance to help them adapt to the climate warming they have done very little to cause, he added.

    More detailed data would enable them to prepare stronger project proposals for international climate funds, including the Green Climate Fund (GCF). In 2025, the GCF backed a project to protect livelihoods from climate-induced flooding in Nepal but it took seven years to get approval.

    Sindhu Dhungana, an alternate board member at the GCF, said the problem is becoming more widespread and urgent for the Hindu Kush Himalaya region.

    “The economies, cultures and almost everything in Himalayan countries depend on mountains,” he explained. “For us, climate change is mountain change… [it has] affected everything, including the economy and biodiversity.”

    Destroyed development projects

    Nepal wants the UN climate process to address mountain risks both before and after disasters. Countries need better research, technology, early warning systems and other adaptation measures to protect people and infrastructure. But even when countries take precautions, loss and damage is likely to occur and will require international support to address it.

    Nepal has been provisionally allocated $21.6 million from the United Nations’ new Fund for Responding to Loss and Damage (FRLD) to help with the aftermath of the Bhote Koshi disaster, but this is just a fraction of needs and the money will come only months after it made an initial request.

    Dhakal pointed to the damage caused by floods to infrastructure built with loans, such as the Melamchi Drinking Water Project, which received $312 million from the Asian Development Bank but was destroyed by a major flood in 2021, shortly after it began operating. The recent Bhote Koshi disaster wiped out a dozen hydropower facilities, as well as solar energy systems.  

    Nepal flood destruction shows “limits to adaptation”, scientists say

    Nepal wants international discussions on what should happen when climate-related disasters destroy development projects built using credit, and how the loans should be treated afterwards.

    “Climatic disasters wash out… projects, but the burden of loan is still paid by Nepal,” Dhakal said.

    For now, it remains unclear whether the opening session of COP31 will consider or adopt the proposed agenda item on mountains and climate change, with consultations on how to respond still underway among governments and the COP31 co-presidencies.

    “If countries agree to discuss the proposal and include it in the agenda, that would be another step forward,” Dhakal said. “Further discussions in the coming years could gradually give the mountain agenda a stronger shape.”
